The Barcelona connection

Luis Enrique arrived at the Camp Nou famous for being a man that likes to take care of every tiny detail. One of the most striking techniques that the manager uses is the use of advanced technology during the game to improvise and adopt new tactics on the fly.

It is common to see Juan Carlos Unzue, his assistant manager, wearing an earpiece with which he receives vital information. But who is at the other end of this technology and what is being said?

Two people from Luis Enrique’s team position themselves higher up in the stadium. From their elevated position, Robert Moreno and Joan Barbara can see how everyone is moving around on the pitch, the spaces that are being made, the chances that might be had. With this privileged information, they speak directly to Unzue down in the dugout, who in turn talks to the Barca manager.

Barbara has known Luis Enrique since the Asturian coached Barcelona’s B team. The man’s keen eye and experience in evaluating the other team’s strengths and weaknesses are invaluable. What he thinks is relevant he tells Moreno, who passes it on directly to Unzue wearing the earpiece.

This way of working is nothing new. Guardiola used the mobile in his time at Barcelona. One of his assistants used to talk to him on the phone from high up, giving his perspective of the game. The man doing the calling was Carlos Naval. Today, Luis Enrique has now perfected the technique that he adopted when training Barca B in the 2010-11 season.

Martian Homes Could Be Built In Just 24 Hours

By the end of this century, it seems highly likely that people will be living on Mars. It sounds utterly mad, until you consider that there were only 66 years between the first powered and sustained Human flight and Neil Armstrong setting foot on the moon…

However, a major problem with this idea (aside from the fact that no Human being has ever actually set foot on the red planet) is the difficulty posed by building habitation in such a hostile and extremely remote environment.

At the moment, even landing an unmanned rover on Mars represents a major scientific achievement, which makes Elon Musk’s plans to build a city there seem especially far fetched and ambitious.

Besides, at current costs, taking one kilogram of material to the moon costs between £61,000 and £122,000. That’s a lot of money, even for bare essentials like building materials and water reserves.

Now, however, one man thinks he may have the answer…

Dr. Behrokh Khoshnevis of the University of Southern California’s Viterbi School of Engineering is working on a groundbreaking new method of building that, if applied to lunar or Martian colonisation, could bring us all that much closer to seeing cities on Mars or the moon in our lifetimes.

Essentially, Dr. Khoshnevis has come up with a way to ‘print’ buildings.

The construction technology, called Contour Crafting, fashions an entire building, layer by layer, according to a predetermined outline. Khoshnevis initially created the technology in order to provide cheap, quick and safe housing for emerging nations, or victims of natural disasters.

It is hoped that such building methods will also lower the demand for wood, thus having a beneficial effect on the rainforests and other areas that are being aggressively deforested for timber.

In addition, the concrete walls built by the Countour Crafter are three times stronger than a brick wall.

Writing for Nasa, Dr. Khoshnevis said, “Automated building technologies will revolutionize the way structures are built on Earth, in dense urban environments, in difficult-to-build and difficult-to-service sites, or in remote and hostile regions of the globe. The technologies under development by our group have the potential to simplify construction logistics, reduce the need for hard physical labor by assigning humans to a strictly supervisory role, eliminate issues relating to human safety and produce intricate, aesthetically refined designs and structures at significantly reduced construction cost”.

Theoretically, these buildings could be described via a computer model and built remotely, using the Martian landscape in lieu of bricks and mortar. The buildings could be ‘printed’ in around 24 hours and would be every bit as strong, (or stronger) than the building you are currently living in.

What Type Of Kenwood Radio Earpiece Should You Use With A Kenwood Radio

Although there are multiple types and designs of Kenwood radios out there, there are only two earpiece connectors compatible with these radios. Kenwood has been able to design their earpiece connectors in such a way that they are compatible with all their vast types of radios. A large percentage of Kenwood radios utilize the 2 pin earpiece connector. Among the most popular radios using the 2 pin earpiece connector include TK3000 and TK3300. The difference between the two-pin connector and the multi pin connector is straightforward. The former features two pins while the latter features multiple pins. However, their performance may not be the same depending on usability and the type of Kenwood radio.

The Two-Pin Earpiece Connector

The earpiece of the Kenwood 2 pin connector is featured by an incredible in-line push-to-talk button (PTT) with an in-built microphone. In addition, it comes with a complete clothing clip and a surveillance acoustic audio tube. This Kenwood earpiece connector can be used with most of the Kenwood radios and it normally sells out at a fair price.

This Kenwood radio earpiece connector is Kevlar reinforced for added security. It also features a secure fit tube connector as well as the lapel clip button. These features integrate themselves easily thus ensuring that the final sound output is of high quality. They are also designed with hi-tech microphones which help in reducing the noise level. Unlike other connectors, its wire PTT (microphone) and acoustic tube are separate. This is meant to reduce the amount of vibrations and echoes produced which would otherwise compromise the sound quality.

When it comes to style, the Kenwood radio earpiece connector is a RoHS compliant connector which has the ‘Over the ear’ FBI style acoustic tube which helps in monitoring sound levels. When you see that the plugs have worn out, there is no reason to worry because these pieces feature replaceable mushroom plugs. This is a changeable earpiece connector which allows you to change the connector to the accessory available. Apart from being compatible with Kenwood two-pin, it also works well other devices such as Motorola 2 pin and Icom 2 pin.

The Multi-Pin Earpiece Connector

The Kenwood multi-pin connected earpiece is a unique and tech savvy type of earpiece. But the earpiece is the same to the 2 pin connected earpiece in other areas. For example, both of them share very important features crucial to the audio type produced. Some of these identical features include an in-line PTT button, the surveillance acoustic tube and the clothing clip. When it comes to its value, it is a little bit pricy than the two-pin version.

The Kenwood Radio Earpieces

The performance andkenwood can be fostered by spending a little bit more on optional features such as the ‘swivel’ ear loop. Also, you can enjoy better use and comfort by including a steel clothing clip that reduces noise. Kenwood composes their earpieces from high quality cables featuring a toughened surface. The durable surface protects the cable from accidental strain and offers exemplary cushion to wear and tear. These pieces are lightweight allowing them to be carried and used in wherever you travel. They have been designed to withstand consistent strains common with all earpieces making it easier to be used in any environment.

Actually, the types of connectors which are compatible with Kenwood radios are limited compared to its counterparts. Nevertheless, the Kenwood two-pin and multi-pin connectors provide an excellent performance in all Kenwood’s radios making other connectors of no importance. But some people would say it is worth trying using other connectors to taste the difference. Kenwood radio earpieces consist of polycarbonate microphones which cushions your ears from unexpected high sound levels. When the acoustic tube gets damaged it can be easily replaced ensuring that communication remains uninterrupted. Also, the button or the controller is strategically placed allowing easier management of communication.

Most of Kenwood 2 way radios may only be connected by the two varieties of connectors. Thankfully, their equipment is among the best and it can hardly be rivaled. If you would want to have a Kenwood radio for your company, it is futile searching other compatible connectors because the aforementioned two works superbly. Many companies have started using Kenwood radio earpieces because of these hi-tech unparalleled features. Remember that, to gain advantage of uninterrupted communication, safe audio output and additional exclusive capabilities you will have to consider a good earpiece connector for your radio.

Record Calls (Literally) On The Go With Bluewire

Today’s smartphones really live up to their name, as they are filled with almost every tool we can imagine. From cameras that are more potent than most compact ones to high-end processing and computing power, they are as good as the next personal computer – I know for a fact that my actual phone is way better than the first computer I had, more than a decade ago.

There is one feature that most, if not all, smartphones come with by default, that is actually not used by most people: call recording. While the feature is quite handy on a situation where the phone is being used the normal way, there are some situations where it is not so much, like when you are using an earpiece and are away from the phone, not being able to hit “record”.

In fact, this is exactly the gap that Bluewire wants to fill. Developed by Senss, it is a project looking for financing on Indiegogo, and is announced as the world’s smartest Bluetooth headset call recorder, which is probably right. Using a common Bluetooth connectivity, it has the ability to record both ends of a smartphone or VoIP conversation, being also able to store it securely on the device itself.

20150114210418-13

Bluewire is an earpiece itself but, if a user already has one and prefers to use it, that is not a problem, as Bluewire can record whatever call is passing through the phone. It has 16GB of memory, Qi wireless charging, built-in flashlight, accelerometer, two-way communication, and several other interesting features.

One of those features is NFC, Near Field Communication. If Bluewire is tapped to a smartphone after a phone call is made, that last call will be transferred and saved to the phone and sent to the user’s email inbox. Bluewire works as far as 33 meters from the smartphone.

Do you find Bluewire useful and plan to pledge for their Indiegogo campaign? Let us know in the comments.

New Sighting Suggests That Extinct Tasmanian Tigers May Yet Live

The Thylacine, an odd, chimera-esque carnivore native to Tasmania, was officially declared extinct in 1986. By that time, no one had seen a live one in 40 years, so it seemed reasonable enough to conclude that a virulent, century-long concoction of wholly barbarous (yet officially sanctioned) hunting methods, disease, deforestation and competition from other predators had wiped the creature from the face of the earth.

However, that may not actually be the case, as recent sightings, including one reported in January of this year, seem to attest.

So convincing are such regular sightings to scientists, cryptozoologists and other interested parties, that a new expedition was launched at around the same time, with the hope of finally capturing proof of the animals long-rumoured survival.

An elusive predator last seen alive in the mid 1930’s, the thylacine, colloquially known as the Tasmanian tiger, has captured the hearts, minds and imaginations of conservationists, explorers, cryptozoologists and, just possibly, a handful of lucky eyewitnesses, for three successive generations.

Dog-like in both size and form, but with an oddly angular head, an enormous gape and chocolate brown stripes running across its tail and back, the thylacine was Tasmania’s apex predator. It was the marsupial equivalent of a wolf, or wild dog (an example of what biologists call convergent evolution) and it existed in Australia and Tasmania for around 23 million years.

The last officially recognised wild Thylacine was shot and killed by a farmer named Wilf Batty in 1930. Six years later, Benjamin, the last captive specimen kept in Hobart zoo, died from a cruel combination of neglect and exposure.

Derided as a pest and a sheep stealer, the extermination of these beautiful, shy and enigmatic twilight hunters was seen, at the time, as a positive step towards the taming of the Tasmanian wilderness.

However, by the time the creature’s numbers had almost completely diminished (if not actually expired entirely), it had become the first poster-child for conservation, an idea practically unheard of before the early 20th century. The Tasmanian tiger was even among was the first animals to be classified as an endangered species.

Concordantly, there is a suggestion that a collection of individuals were shipped over to the Australian mainland and secretly released into the wild there, as an act of conservation.

However, despite the aforementioned declaration of the thylacine’s extinction, evidence occasionally comes to light which suggests that rumours of the Tasmanian tiger’s death may be somewhat exaggerated.

In South Australia, 1973, a very compelling piece of footage was taken on 8mm film stock. The footage appears to show a thylacine running across a rural campsite. The gait and running style are entirely unlike a dog or dingo’s and the animal’s lithe, slender form and bony, tapering tail, potentially offer us a tantalising glimpse of a creature that just may have survived extinction.

In 1985, yet more photographic evidence was offered, this time by Australian Aboriginal tracker Kevin Cameron, who photographed what appears to be a thylacine digging in the ground behind a rock.

In 1982, Parks and Wildlife Service researcher Hans Naarding was gifted with an opportunity to observe a thylacine up close for several minutes, even going as far as to count the stripes across its back (12, in case you wondered). A similar account, also filed by a Parks and Wildlife Service employee, emerged in 1995.

Eyewitness accounts of the creature are both numerous and, for the most part, highly consistent. Although some reports are obviously mistaken accounts of dogs afflicted with mange, or even foxes, others still are surprisingly credible.

The most recent sighting of this incredibly rare creature occurred in January of 2014. It was reported to the Thylacine Research Unit (T.R.U), via the organization’s official website.

The eyewitness, named as Jeremy by the site, revealed that he had seen a 40-50CM tall creature that was about the same length as a small dog (defined as 1metre), whilst out walking in the Landsborough area of Queensland, Australia, not far from the Dularcha National Park. According to Jeremy, the creature had light, sandy coloured skin and faint stripes across its back and tail.

Jeremy says, “As I watched it from the side angle, I saw its head appear and thought, oh its a wallaby, but as it emerged I saw it was on four legs, so thought it was a wild dog. But as it went away into the next thick bush, I noticed light coloured stripes at the rear near its tail”.

Once the animal had retreated into a more heavily forested area, Jeremy decided to “let it be” and tell his friends about what he’d witnessed. Apparently, Jeremy’s girlfriend later revealed that she had also seen the creature in the area.

Emphatic that neither of them had seen a dog, or a dingo, Jeremy searched exhaustively online for any kind of striped, dog-like marsupial, but came up empty handed. There was only one logical conclusion.

Proponents of the thylacine’s continued survival often argue that sightings are increasing because the animal’s population may be enjoying a recovery. It has been estimated that if a breeding population of tigers did survive the 1930’s extinction, that it would take them a reasonably long time to return to sufficient numbers. If that is indeed the case, then 70+ years ought to do nicely.

Hopefully, it should now start to get easier to spot, and conclusively document, a living, breathing 21st century thylacine.

A Look At The Different Motorola Radio Earpieces

When it comes to discreet affairs, there definitely must be a discreet communication. Whether it is a security personnel or just a private group of designated people. Radios are used for communication between compatible devices within a specified location. Nevertheless, it would be less comfortable if someone talks via the radio and everyone hear the entire communication. Given the different types of two-way radios in the market, they usually come with a compatible earpiece. Among the most common radios are the Motorola radios. It would be super discreet and stylish if you had AMotorola radio earpiece to accompany your device. Some of the ideal Motorola 2-way radio earpiece connectors at EarpieceOnline include the following;

CP040 DP1400 2-Pin Connector

This Motorola 2-pin connector can work with a number of Motorola 2-way radios. It can also support some of the old version radios such as the DP1400, GP040 and the GP300. Some of the novel version of radios that are compatible to this earpiece include the DP1400 and the DP1000.

Features of the connector

* It has a changeable Foam sock so that you can replace if it has worn out.

* The earpiece also has a comfortable and flexible C-shaped earpiece.

* There is a secure moulded ear hook, for holding firm on the ear.

* It provides high quality audio.

* It comes with a noise reducing microphone for enhanced reception of incoming voice messages.

* The earpiece has a plastic that is covered by a label clip PTT button. The wire PTT is separated from the microphone and an ear hangar earpiece.

* It has a RoHS compliant feature and comes with Motorola earpiece 2-pin connector GP300/CP040/XTN/DP1400 and GP340 adapters.

DP3400 DP3600 Multi Connector

This is a multi pin connector works with all DP3000 DP4000 range of radios, with a 12-pin connector, it slots perfect onto the side of the DP radio and is securely screwed in so that the earpiece is securely locked in.

Features

* It is incorporated with Kevlar Reinforced for better surveillance and security.

* It has a secure fit tube connector, to avoid accidents of it cut from rough encounters.

* It offers a high quality audio.

* The earpiece has a Lapel clip PTT button and a separate wire PTT. That is separated from a noise reduction microphone and an acoustic tube. The acoustic tube runs over the ear, the FBI style.

* There is a changeable connector for flexible modification and flexible mushroom plugs that you can replace whenever.

DP2400 DP2600 multi connector

This is yet another different multi-pin connector that lets you connect to the DP2000 range of radios. This 8-pin connector fits on to the side of the radio and is locked in with a ‘pull out and slot-in’ connector, reducing the risk of broken screws or damage to the radio.

Features

* The acoustic tube runs over the ear and it has a secure fit connector for super surveillance and comfort.

* It has a separate wire PPT different from the acoustic tube and a microphone that reduces noise from the surrounding.

* The mushroom plugs are changeable and you can simply remove them when they are loose or worn out.

* It produces a high quality audio that reduces strain even when in a noisy environment.

GP340 GP680

This multi connector is compatible the GP range of radios, including the GP340 and GP680. The Connector is a 13-pin connector and is secured on the side of the radio, with a screw-in to secure the earpiece to the radio.

Features

* This multi connector has a high quality audio reception. That makes it comfortable to use anywhere, even in a crowded, noisy place.

* There is a microphone, which is separate from a wire PTT and an acoustic tube. The microphone is a noise reducing microphone, that helps to make the other end-user be comfortable.

* It has a RoHS compliant and an over the ear acoustic tube that holds firm to the ear.

* There is an adjustable connector that is versatile to other devices.

An elegant and well fitted earpiece will not only promote surveillance, but it will also be comfortable on the ear. That will ensure it is safe from damages in rough situations. A Motorola radio earpiece will be beneficial if you want a comfortable communication without having to speak loudly over the radio. Some of the radios are also slightly heavy, which makes them more comfortable when using an earpiece, that is worn beneath the clothing.

Weitz Funds Analyst Corner – A Perspective On Motorola Solutions Inc.

Motorola Solutions (MSI) is a global leader in the sale of public safety communication infrastructure products and services as well as commercial radio systems. The company’s public safety portfolio, which represents over 60% of sales, provides first responders with mission critical, reliable and secure communications necessary for operating during storms, fires and security events where the inability to communicate can result in disastrous consequences. MSI designs, manufactures and installs the underlying infrastructure necessary to run a network as well as the end point radios and other devices carried by local personnel. The company’s commercial radio systems are sold to a diverse set of private and public entities which need a reliable, low cost, two-way push-to-talk method of communicating with customers and employees. We believe the company is the share leader in both of its primary businesses, serving over 10,000 customers located in more than 100 countries.

Old is New Again – With Higher Margins

Motorola was originally founded as Galvin Manufacturing in 1928 with the police radio as one of its first products. In its 86 years, the company invented or commercialized many leading edge products such as the AM/FM car radio, two-way police radio, walkie-talkie and the first cellular phone and network. Over time, Motorola became the owner of a wide range of technologies pertaining to semiconductors, personal computers, mobile phones, cable television and networking equipment. In the early 2000’s the company began a program to divest many of its disparate businesses. With the appointment of CEO Greg Brown in 2008, the divestment program was accelerated through the spin-off of the mobile phone unit and culminated with the sale of the enterprise mobility products business in the 3rd quarter of 2014. MSI management believes that as a result of being able to completely focus on what are two very similar businesses, it will be able to reduce selling and overhead expense and therefore increase operating margins by a significant amount.

Analog to Digital LTE: Opportunity or Threat?

While shrinking its portfolio, Motorola was also investing in the public safety and commercial radio businesses. By refreshing and expanding the product portfolio MSI is well positioned to participate in what is expected to be a long-term transition by customers from aging analog to modern digital and LTE systems. MSI estimates that only 60% of its install base has moved to a digital infrastructure which among many improvements allows for better quality, more efficient use of spectrum and lower costs. The company has long protected its customers by making new equipment compatible with older versions so customers can transition to digital as needed without worrying about obsolescence.

A rush by MSI’s customers to comply with an FCC mandate caused some of the “digital transition” demand to be pulled forward from 2014 into 2012 and 2013. The resulting lull caused negative year-over- year sales growth and created doubts in investor’s minds about the durability of the public safety business. We anticipate that public safety revenues will return to growth in 2015.

Another source of opportunity for MSI is to sell LTE data capabilities into its installed base. LTE systems complement existing digital systems by offering features such as high-speed, two-way data transmission, real-time video and use of “big data” applications. However, Voice over LTE is barely reliable for consumer cell phone use (most consumer smart phones connect to a “3G” network for voice and use LTE for high speed data) much less critical public safety situations and therefore existing analog and digital voice products must still be used for the foreseeable future. Motorola has patiently built out its LTE offering while it waits for the U.S. Government to settle on rules and standards for a national intraoperative public safety LTE network. The process has taken longer than expected and combined with what we believe are unfounded worries that LTE will cannibalize revenue from the analog to digital transition has caused investors to express concern that LTE is more a threat than an opportunity. Our analysis leads us to believe that LTE has significant potential and will be additive to Motorola’s results.

Strong Capital Allocation

The separation of the mobile phone business in early 2011 left the company with significant net cash. Since then Motorola has repurchased over 30% of its diluted shares. Furthermore, the company has committed to moving to a net debt position thus making available more funds to shareholders. These funds, when combined with the proceeds from the sale of the enterprise mobility business are what enabled the company to authorize an additional $5b in repurchases in November 2014. If fully utilized at current prices the repurchase would reduce MSI’s share count by another 25%. In buying a substantial portion of its shares, MSI has materially increased per share value for remaining shareholders.

Attractive Value

We believe Motorola possesses an above average “moat,” good management and a shareholder-friendly capital allocation policy. As a result, we consider the MSI to be a high-quality business. With predictable long-term growth driven by public safety infrastructure upgrades and margin improvement resulting from focus and scale, we believe our discounted cash flow derived estimate of business in the mid $80’s represents a compelling opportunity for the Funds.

What Do You Do With A Radio Earpiece?

What is a radio earpiece? An earpiece as the name suggests is a piece for the ear that can either be put inside the ear, covering it or suspended next to the ear. Its main function is to transmit sound signals converted from electronic waves. Earpieces can either be wired or wireless and with a variety of designs as well.

Some of its designs and features

Radio earpieces are convenient; especially where the user is constantly on the move. They are stylish and whether they have a cord or not are still presentable and handy. They too have special microphones that enable two way communications. A light inline push to talk button is as well present and it can be detached or attached to the earpiece.

You can have one that is over the ear that is usually quite fitting. It can either be circum-aural whereby it covers the entire ear and is usually large or supra-aural which only fits on the ear without surrounding it. For these radio earpieces to be of good quality, the material needs to be flexible to reduce chances of breakage.

Other features of the different earpiece designs include having reinforcements aimed at making them more secure. You can also choose to have a wireless or corded radio micro phone that works just as well. Some of the covert earpieces will come with their own separate cables of different lengths and easily adjustable volumes.

An earpiece that is fitted inside the canal of the outer ear can also be referred to as an ear bud. A good radio ear bud will not have any negative effect in your ear functioning. It also needs to be comfortable for the wearer.

The one with a sound tube connector is even more secure and makes a perfect fit into the ear. The radio earpiece will also come with wire pieces if one decides to use them. One can in addition have more than one connector with a single radio earpiece. These acoustic tubes will also come with mushroom replacements.

An earpiece worn inside the ear canal will obstruct external sounds unlike the ear bud. It is also possible to have a radio transmitter over the ear that ensures that you get clear and quality sound without influence from the noise in the background. The microphones are also able to reduce the sound in the environment and focus on what needs to be transmitted. Over the ear earpieces come in a number of interesting designs such as the D shaped and the G shaped radio earpieces which are especially favourable if the earpiece is being used by more than one person. They are not only sanitary for sharing but comfortable too.

Advantages of covert radio earpiece

Sometimes it will just seem like one is simply listening to their radio but the earpiece is a great communication tool as well. Most of its advantages are drawn from its unique features.

A radio earpiece comes in handy especially because if it’s small size and its hidden nature. You can easily keep your conversation over the radio private and no one will even know you are on it. This is especially when the information being passed is on a need to know basis.

This makes it the earpiece appropriate for those working under cover, security agents, and police officers or even by the government. It is also good for any other occupation or activity that needs a high amount of secrecy or those involving investigations. Another important feature of the earpiece is its ability to enable free flow of information within that particular time. This communication makes it very helpful in such circumstances when one needs to be regularly updated while performing a particular task. This can be because they need to be given instructions or need to be informed about the progress of something.

However, this in combination with the private and convert properties of the radio earpiece also makes it the perfect device for more sinister motives such as illegal spying or cheat in a game or even a test. On the positive side, this communication is extremely helpful in public speaking when one needs some pointers while on stage or in front of an audience without having the listeners know about it.

Being hands free and portable makes it possible for them to be used in occupations where holding a radio to communicate is not an option. This is for instance in works involving heights or need a lot of precision such as engineering or doing a delicate electrical project.

FIVE REASONS TO MIGRATE TO DIGITAL TWO-WAY RADIOS

In the beginning, there was analog technology, which uses frequency modulation (FM) to produce a continuous wave with the voice signal. An analog two-way radio works as both transmitter and receiver, with that continuous wave in between. Analog has been the primary technology platform since the initial development of wireless communications.

Analog radios have been used for business applications as far back as 1933.

  • Analog Advantages: The integration of such a simple system into a single computer

chip has dramatically reduced the cost of analog radios.

  • Analog Disadvantages: The analog radio system has many functional limitations, and

the technology has been around so long that the scope of possible innovations is virtually exhausted.

ALONG COMES DIGITAL

Digital two-way radios operate by encoding, transmitting, and decoding sound waves. The signal is represented by binary numbers—1s and 0s—that correspond with voltage values. Inside the radio, the vocoder—an analysis/synthesis system used to reproduce human speech—encodes the transmission. The radio sends the signal, and the vocoder on the receiving end decodes it.

In addition, the software in digital radios contains an algorithm that recognizes the difference between voice and background noise and cancels undesirable audio for clearer, cleaner sound quality. Digital two-way radios can also include software applications that integrate into existing computer networks and phone systems. As a result, digital radios can enable a multitude of additional functions, including GPS, text messaging, and other information sharing, communications, and operations programs and capabilities.

By proactively transitioning to digital radios now, your organization will enjoy greater benefits immediately, and your fleet is ready for the high-efficiency, app-driven innovations coming in the future.

FIVE REASONS TO GO DIGITAL

  • Improved Audio Quality • Enhanced Clarity throughout the Coverage Range
  • Greater Efficiency • Extended Battery Life • Applications that Add Functionality
  1. Improved Audio Quality: Digital technology reduces external background noises during

transmission, thereby making the digital technology platform ideal for situations such as

noisy manufacturing and processing plants, or outside in windy conditions.

  1. Enhanced Clarity throughout the Coverage

Range: While an analog radio is capable of producing a clear signal within its peak performance range, once the signal moves too far from the transmit point, the analog audio will slowly fade out until it is unrecognizable. By contrast, a digital signal stays much stronger and clearer to the limits of the coverage range.

  1. Greater Efficiency: Digital radios operate in

Dual-Capacity Direct Mode (DCDM), which means that radios can share the same channel by alternating time slots. These time slots move incredibly fast, and since they alternate, more simultaneous talking paths are possible on each channel with no degradation. Plus, key information such as unit ID, status buttons, and enhanced text messages can be embedded into a single digital radio channel. In many cases, migrating from analog to digital allows users to increase talk paths without a repeater.

  1. Extended Battery Life: Since digital radio transmitters are not constantly “on,” digital

radios generally have a significantly longer battery life than analog models. When events run all day, that can mean the difference between efficient communications for the full cycle or the headache of a number of dead batteries that need swapping out and recharging.

  1. Applications that Add Functionality: Software applications are available to optimize digital

platforms using integrated Internet Protocol (IP) networks. For example, some of the leading app providers for Motorola MOTOTRBO digital radios include:

TABLETmedia

NeoTerra Systems

Twisted Pair

TurboVUi

Teldio

MOVING TO DIGITAL

For those switching from analog to digital, there is good news: Digital platforms provide a migration path that allows for simultaneous use of digital and analog radios. Backward compatibility allows organizations to gradually replace analog devices with newer digital models without the added stress of shifting to a new system. Also, many analog radio accessories are compatible with digital devices.

THE MOTOROLA CP200 AND CP200d

The existing CP200 is one of the most popular two-way radios ever produced! So the question is: How can you improve on the Motorola CP200? The answer: By creating a version that leverages all the benefits digital delivers.

Introducing… the CP200d digital two-way radio, a new model that retains the same simplicity and durability that have made Motorola’s CP200 the industry standard for years. The new CP200d uses a nearly identical form factor with similar operation. Plus, this highly flexible digital model is backward compatible, so it uses the same chargers, batteries, and speaker-microphones.

Motorola is adding sensible options to your two-way radio fleet by offering the existing CP200 device in the CP200d digital-capable version that can be fully converted from analog to digital operation at a later date. That means you can use a phased migration approach by using your new CP200d as an analog device now, and then with a simple programming change, switch to digital at any time in the future. Or, you have the option to take out-of-the-box delivery of the CP200d as a digital device from the get-go.

THE TALE OF THE TRBO

MOTOTRBO is Motorola’s next-generation system of digital portable and mobile radios, repeaters, and accessories. Thanks to the advantages of digital technology, this professional line delivers advanced performance to increase capacity and productivity while integrating voice and data communications.

Versatile and powerful, MOTOTRBO combines the best of two-way radio functionality with the latest digital features that deliver ease of use and added performance to meet your communication needs from the field to the factory floor. With exceptional voice quality and long battery life, MOTOTRBO keeps your work teams connected when communication is a must.

Apreciation for the article goes to %link%

Those tiny earbuds you bring along with you here, there, and everywhere are causing you to go deaf. At least that’s what audio specialist, and in-ear monitor pioneer Stephen D Ambrose would have you believe. To save you from the dangers of the common earbud, Ambrose and his team at 1964|Adel have created an entire new wave of %link% designed with patented technology to be safer for your eardrums, all of which are making the rounds in a new Kickstarter campaign.

The link between hearing loss and headphone use being drawn here is not a new one. For its part, 1964|Adel singles out a study from an L.A. Times report which cites an increase in hearing loss for U.S. teens in the last 15 years from 30 to 77 percent. The study in question ruled out ear infections and external environmental factors as causes, pointing instead to the higher prevalence of portable audio players, though it stopped short of specifically laying blame. That said, there are plenty of other studies blaming the blasting of headphones as a major contributor to hearing loss.

But Ambrose argues that hearing loss from in-ear headphones and %link%, specifically, is different due to the way they isolate the eardrum inside the ear canal. In the video below, Ambrose claims it’s not acoustic pressure (i.e. loud noises) that causes hearing loss, but the pounding of air pressure from the moving driver being sealed inside your ear canal, causing “pneumatic pressure” from the movement of the driver itself.

In response, Ambrose and 1964|Adel have proposed a new way to solve the very hearing loss epidemic Ambrose claims to have helped create with his original in-ear monitor design; four ways to be exact, stemming from four different headphone series. The new headphones employ 1964|Adel’s patented RealLoud Technology, which incorporates a “second eardrum” inside the earpiece designed to take the brunt of the air pressure to protect your real eardrum. The company even claims the design makes audio “sound louder,” requiring a lower overall volume level.

The first, and most affordable solution in the arsenal is the new Adel Control, a modular earphone that allows users to adjust features like bass and external noise to taste, tailoring the sound signature. At time of publication, the Control was still available as an Early Bird special for $100, half off the suggested retail price.

Next in line is the Adel Ambient series, which offers 4 multi-driver models, from the entry-level dual-driver Ambient 2, to the Ambient 12 which (you guessed it) is jam-packed with a whopping 12 drivers per side, labeled the “jewel” of the Ambient line. Pricing for the Ambient series starts at $200 for the dual driver set, and goes up to an impressively (relatively) affordable $500 for the 12-driver version, again, priced at half the cost of suggested retail for each. For reference, the quad-driver Westone W40 will run you the same price as the Ambient 12.

Next up are the 1964|Adel U-series, which take the shape of more traditional in-ear monitors, covering the entire ear canal. The U-series starts with a quad-driver pair for $300 — down from a suggested $500 retail price — and the series goes all the way up to the 8-driver U-series 8, which will run you $720. The latter offers 4 drivers for the bass register alone, with two each for the midrange and treble, to create a massive sound.

Finally, the 1964|Adel A-Series includes both 10-driver, and 12-driver models, priced at $1,000 and $1,200 respectively — 40 percent off the claimed MSRP. Like most top-tier in-ear monitors, the A-series are custom tailored to the user’s ears for the ultimate fit and sound, while harboring a RealLoud secondary eardrum for safety.

Not only is 1964|Adel’s new project already funded, but it has already reached its stretch goal of $350,000, which provides an optional inline 3-button mic piece for all of its headphones. All of the new models are slated for release in May of 2015, with the exception of the A-series, which will be available earlier in February.

While we certainly can’t attest to the claim that RealLoud Technology actually makes these headphones safer, they are priced very competitively under the Kickstarter deal. And hey, if they offer competitive sound in their respective genres, what’s the harm in playing it safe, right? If you’re interested in finding out more, or ordering up one of 1964|Adel’s latest designs, you can do so today at its Kickstarter page.

Study ‘makes the case’ for RFID forensic evidence management

What is your favorite feature of my two way radio? In my opinion, I like the design job – It is cooler than an Inuit’s underpants!

Radio frequency identification (RFID) tags—devices that can transmit data over short distances to identify objects, animals or people—have become increasingly popular for tracking everything from automobiles being manufactured on an assembly line to zoo animals in transit to their new homes. Now, thanks to a new NIST report, the next beneficiaries of RFID technology may soon be law enforcement agencies responsible for the management of forensic evidence.

A typical RFID system consists of a microchip programmed with identifying data—the “tag”—and a two-way radio transmitter-receiver, called an interrogator or a reader depending on its use. The tag can be attached or embedded in the item to be tracked, with the radio either sending a signal to the tag or reading its response.

Common examples of RFID systems include the FasTrak and E-ZPass in-car tags for automatically collecting tolls, tagged prescription drugs that help pharmacies meet federal and state safety regulations, and credit cards with embedded RFID chips that provide a more secure way of transmitting card numbers than magnetic strips. RFID systems can read hundreds of tags in a few seconds and track an item as it moves through a process. More advanced RFID tags can sense and report on environmental conditions, or encrypt the data they send.

While some have used barcodes to improve their tracking, storage and retrieval processes, very few have implemented RFID because of concerns about startup costs, the reliability of the technology and the current lack of relevant RFID standards for property and evidence handling. To help agencies better understand these issues and properly assess the pros and cons of RFID evidence management, NIST recently published RFID Technology in Forensic Evidence Management, An Assessment of Barriers, Benefits, and Costs. The report is the result of a NIST-funded study on automated identification technology (AIT). The Technical Working Group on Biological Evidence Preservation, cosponsored by NIST and the National Institute of Justice (NIJ), commissioned the study and report.

The NIST report includes a helpful overview of AITs—focusing primarily on RFID and barcode technologies—and how they work. It describes, in depth, the types of RFID systems available (passive, active and battery-assisted), their price ranges, and the components necessary for a complete system. The report also details the barriers that agencies may encounter, followed by a series of successful RFID management case studies, including examples from the pharmaceutical and retail industries, and one law enforcement agency that has made the switch, the Netherlands Forensics Institute.

The practical question that agencies must consider—and one that the NIST report can help them answer—is whether RFID technology can produce measurable benefits and a positive return on the funds invested in a new system. The NIST report estimates that RFID systems can pay back their initial set-up cost in about two years.

Various factors can affect the payback period. For example, systems that track and manage larger inventories of evidence (100,000 or more items) will recoup costs more quickly than those handling smaller inventories. However, if multiple jurisdictions share the costs of a system, the payback period can be shorter.

Whats’s a Covert Earpiece?

Thanks for reading my blog, here is an article i really loved reading. With their permission i can repost it. I write tons of my own content, but occasionally post other articles i find remarkable, thankyou for reading.

A covert earpiece is a miniature earpiece worn by an individual while being effectively hidden from plain view. It operates as a radio accessory in times when a user does not want other people to know she or he is communicating with others using radio earbuds. Also known as an invisible earpiece or a surveillance earpiece, a covert earpiece is often worn by government agents, corporate security personnel, undercover law enforcement officers and corporate as well as government spies.

covert earpiece

While many occupations require the use of a radio headset for communication, a covert earpiece is primarily used in instances where communication is of an extremely private and sensitive nature. This is common in cases of private security details and surveillance projects. Sometimes people also use a covert earpiece to defraud businesses and others. Examples of such instances would include someone using an invisible earpiece to cheat on an exam or to defraud a casino by receiving remote information while playing a game.

On-air television personalities may also use a covert earpiece, which is not distracting to viewers, but allows the person to hear relevant feedback from producers and engineers in order to make sure a taping or live appearance flows smoothly. Individuals may also wear a covert earpiece when making a public speech. By doing so, the speaker can receive important cues or changes in a speech without the audience even being aware that communication is taking place between someone located behind the scenes and the individual delivering the speech.

Some covert earpieces are accompanied by a discreet microphone, which enables two-way communication. These are commonly used by security forces with a need for such communication, particularly during surveillance operations. These types of accessories are not only convenient because they feature hands-free operation, but also because they allow undercover security forces to blend in with crowds without having to use a visible walkie-talkie system of communication.

A covert earpiece does not contain any visible wires and is designed to fit inside the ear without being noticeable to the general public. Some devices are even designed to fit on a pair of eyeglasses while amplifying sound inside a person’s ear. An inductive wire is sometimes worn around the person’s neck, but is covered by clothing so as not to be discovered by onlookers. This wire is not connected to the covert earpiece, but connects to a separate radio device that helps modulate sound.

Kickstarter marketing campaign launched for an earpiece using biometric sensors

What would you do if i stated I had found a radio accessory piece that isn’t only interesting but informative also? I knew you would not believe me, so here it is the informative, excellent and appealing article

Research and development firm Sensogram Technologies announced it has launched a Kickstarter campaign to raise $250,000 to supplement the manufacturing and refine its wearable health and fitness device, SensoTRACK.

SensoTRACK is able to simultaneously measure and monitor heart rate, respiration rate, oxygen saturation and blood pressure in real time, as well as many other parameters including calories burnt, step count and geophysical location.

Launched on October 14, the Kickstarter campaign is set to run for 60 days through December 12.

Available in six different colors, SensoTRACK will initially be offered in limited availability by February 2015, then expand to full-scale production in the second quarter of 2015.

Though the suggested list price is $245 per device, it is now available for pre-order on Kickstarter for $199.

Operating either as a stand-alone device or a tablet to upload data to a secure cloud server, SensoTRACK can be worn on the ear to wirelessly sense, monitor and track a user’s performance.

SensoTRACK’s algorithms analyze, interpret and present the data in a dashboard display, while the platform allows users to share fitness routines with other users via the cloud platform.

“Whether you are an elite athlete or someone who wishes to chart progress toward greater health, fitness, or just well-being, the feedback SensoTRACK provides can help motivate the owner of the device to reach her/his goal,” said Dr. Vahram Mouradian, founder and chief technical officer of Sensogram Technologies. “Information is power, and SensoTRACK offers users the power to sense, track and manage personal fitness and activities, motivated by the improving health results.”

After four years of development, testing and refinement, SensoTRACK will be manufactured by development partners in Plano, Texas who are in compliance with ISO Standards in both electronics and medical manufacturing.

Have You Ever Thought How Do 2 way radios work?

To put it simply, a two-way radio is a device that can both receive and transmit voice messages. In broader terms, it can be said that most wireless communication, and it may include cellular systems, fall under the definition. However, these days, two-way radio is a term to describe radio system for group call communication. The two-way radio comes in several technical names such as Public Access Mobile Radio, Private Mobile Radio, Land Mobile Radio and Professional Mobile Radio. These present times, two-way radios are often called “walkie talkies”. There are several kinds of two-way radio systems and some are able to make use of base and mobile configuration, while some re able to utilize a radio network infrastructure.

A typical two-way radio includes a PTT button, also known as Push-To-Talk button. The button activates the transmitter and the user simply needs to talk to the device to start communicating. The user must release the PTT button in order to receive transmissions from the other line.

A two-way radio is able to communicate with other radio devices. However, direct radio communication has very limited range. To overcome the problem, a radio network infrastructure may be used to extend the range of communications. The rest of the article is going to cover more details about how 2 way radios work and other useful information.

Receiving Radio Waves

Just like other forms of Wireless communications, a two-way radio sends messages over the air. In order to achieve this, the antenna of a way radio contains a specific set of electrons. If the two-way radio features multiple channels, then there is specific sets of electrons are each channel. Whenever a radio transmission is received by the two-way radio, the electrons get excited. The electrons then create electrical impulses. Electrical impulses are then sent to a small processor, which will then convert the electrical impulses to words and sounds that can be understood by humans. The sounds are produced by the speakers within that two way radio.

Keep in mind that there are always radio waves are floating in the air. Because of it, there is always a nondescript sound that may be produced by the two-way radios. To solve the issue, a lot of two-way radios feature a “squelch” setting; and with it, the user can adjust the signal threshold for clearer communications.

Sending Transmissions

Two-way radios can also send messages across the air. The main idea is to convert the sound to radio waves. However, the defining characteristic about the way radio is its ability the convert back the radio waves back to legible sounds.

Whenever a user speaks into a two-way radio, a membrane within the device will vibrate as a response to the sounds. The vibrations are sent to the processor, which in turn converts them to electrical impulses and readies it for transmission.. Finally, the transmission is sent to the antenna which is then broadcasted in the form of radio waves. These radio waves are then received by another device and convert them back to a legible sound.

Multiple Channels

As two-way radios are getting more and more popular, it is possible for more than one party communicating in the same line or frequency. This can cause a lot of confusion and interference. To solve the problem, modern two-way radios are able to utilize multiple channels.

For a two-way radio to broadcast on multiple channels, the device must be able to generate radio waves in multiple frequencies. Furthermore, the device must be able to send frequencies with very little fluctuations. These fluctuations are actually caused by the transmitted voices. The fluctuations can be minimized through “frequency modulation”. The modulated transmissions are then sent to the device’s antenna.

The device must also excite the proper electrons. Once the proper electrons are excited, an outgoing radio wave is then produced.

These radio waves may be picked up by another device tuning into the same frequency. Furthermore, the device must be within range of the transmitting device. The range of two-way radio is usually determined by a couple of factors such as atmospheric conditions, radio’s battery power and the size of the two-radio’s antenna.

Whenever a device picks up the transmission, the receiving radio must filter the signals through an electronic filter known as a bandpass filter. Finally, the transmission is then converted back to sound.

Why Choose A Two Way Radio

The two-way radio is one of the earliest forms of wireless communication. However, in today’s modernized communication environment, a question arises – is the way radio a viable technology? The answer to that question is a yes. This is because the two-way radio has its own unique advantages that may not be found in other forms of wireless communications. Below are two of them:

Instant Communication – the ability to communicate between two or more parties almost instantly is one of the most defining advantages of the two-way radio. A user only needs to press the “Push-To-Talk” button and within seconds a receiver will be able to receive the audio messages. Furthermore, the entire system is set up around the idea of “quick call” and “quick receive”. This is the main reason why the organizations rely on the two-way radio technology for operational and tactical communications. The system can also make use of encryption technology for a more secure communication.

Group Communications

Another unique advantage of two-way radio is its ability to facilitate “group call” or “one-to-many” communications very efficiently. By efficient, it means that the user can communicate with one, hundreds or thousands at the same time. There is no need for a user to repeat the same message if he/she needs to communicate to more than one individual.

A two-way radio is one of the earliest technologies used for wireless communications. Even though it is a bit outdated compared to other forms of wireless communications, but the usefulness is still very applicable today. The main idea of how 2 way radios work revolves around on sending and receiving radio waves, which in turn is converted to legible sounds. The idea and technology behind two-way radio may be simple, but nevertheless it is still a very well-used form of communication in today’s world.
