New Bluetooth Smart Wallet Thwarts Thieves



Did you know 43% of most known cases of identity theft occur through stolen wallets and not hackers? That’s what the makers of the Ping wallet are banking on. Ping is a super slim aluminum Bluetooth® Smart wallet. When you take your cards out or forget to put them back in, it emits a sound. If you lose your Ping or it goes out of range of your smartphone, your smartphone emits a sound to either help you find it or alert you it is missing. If your smartphone goes out of proximity, the Ping wallet emits a sound as well. The wallet is a current Kickstarter project with a few more dollars to go by the deadline. This option for a Saturday night might be a good bet if you decide to have too much fun out on the town, at least you can keep track of your money and identity.

A Hard Bluetooth Pill to Swallow



Tracking patient medication is a tough thing to do. We’ve seen the movie with the mental patient hiding his medication in his cheek. Proteus Digital Health developed a bill that texts an alert when it reaches the stomach. The pharmacist adds the pills to a specially prepared tray housing all the patient’s medication. When the patient downs the sensor, caregivers assume the patient took all the medication.
Once the sensor reaches the stomach it powers up using electrolytes. It transmits a signal via Bluetooth® technology and a special patch worn on the torso to a smartphone or secure patient database. We’ve seen any different use cases of Bluetooth Smart in the medical industry recently. This is just another example of how Bluetooth Smart helps monitor patient health and helps doctors provide a more holistic diagnosis.

It’s 15-Love for New Bluetooth Tennis Racquet



Babolat introduced the world’s first Bluetooth® enabled tennis racquet, the Babolat Play Pure Drive. Like any other sport, it’s important to be able to gather athlete information to improve performance. The Babolat Play collects data like shot power, ball impact location, number of strokes (forehand, backhand, serve and smash), spin level, total and effective play time, endurance, technique, consistency, energy and rallies. After collecting all the data, the Bluetooth Smart connection sends the information to a smart device. Players can then evaluate performance or share the information through a dedicated platform.

Track Environmental Radiation Exposure with Bluetooth Sensor



I was just thinking to myself the other day I should really be continuously monitoring my background radiation. Enter DO-RA, the dosimeter-radiometer that continuously monitors background radiation. The Bluetooth® enabled sensor attaches to your smartphone and measures the amount of radiation received by the owner, gives off a warning if the radiation dosage is too high and transfers the collected data to any electronic device.
Intersoft Eurasia developed the appcessory in response to the Fukushima Daiichi nuclear disaster in Japan. The sensor takes measurements every four seconds and measures exposure over time to forecast annual exposure. The company is designing a concept watch to take the place of the smartphone and is looking into building a sensor directly into the phone.

Half of Bluetooth enabled devices shipped in 2013 will be Smart ready

Bluetooth Smart node devices accounted for less than 10% of total Bluetooth 4.0 devices shipped in 2012. However, as device vendors have embraced the technology a wider ecosystem of vendors have gained confidence in 4.0 and it is emerging as the key wireless technology in a whole range of devices from heart rate monitors to door locks. Apple has been a key adopter and driver of Bluetooth 4.0 and vital in driving the initial growth; with the recent addition of native 4.0 support in Android a whole new slew of device manufacturers will now embrace 4.0, according to ABI Research.
"The second stage in the growth cycle for Bluetooth v4.0 is driven by its use in wireless sensors and other node devices," said Peter Cooney, practice director at ABI Research. "We have already seen swift adoption of Bluetooth 4.0 in the sports and fitness market, home automation applications are on the rise and no doubt the wearables sector, including smartwatches, will also drive this market forward."
The total Bluetooth enabled device market is expected to go beyond four billion devices shipped annually in 2017 and as the market expands it is increasingly being driven by devices that are 4.0 enabled. It is clear that the development of ultra-low power Bluetooth has, and will continue, to keep Bluetooth as a relevant technology in the burgeoning Internet of Everything market

Why Bluetooth use is on the rise




Bluetooth has been with us for around 15 years. Named after Denmark’s King Harald "Bluetooth" Blatand, who reigned in the 10th Century AD, it is a technology that everyone is aware of on their computers and phones, yet not many people choose to use. As a means of allowing devices to talk to each other cheaply and wirelessly over short distances, it has tended to stay largely in the shadows, leaving the limelight to the technologies it connects.

Now however, with the rapid growth in the use of mobile and sensing technologies, along with the release of an updated version of the system, means the list of its applications is growing steadily. From health and agriculture, to business and electioneering, it is quietly playing an ever more central role in many of our lives.
“It’s a very flexible, low power, and predictable technology,” says Professor Roch Guerin, Chair of Computer Science and Engineering at Washington University, St. Louis. “Bluetooth targets lower transmission ranges and data rates than wi-fi, and as a result has lower cost and lower power consumption.”
These costs have dropped further, in some cases significantly, thanks to recent advances. Bluetooth Smart, launched in 2011, includes a smarter power management system that allows it to turn on, transmit data and shut down more quickly – in just a few milliseconds in some cases. Depending on the devices being connected and the data being transmitted, this updated system consumes anywhere between half and 1/100th of the power of the previous version. As a result, machines using Bluetooth that previously ran for a few months on a coin cell battery, can now run for years.
“Bluetooth classic is for sending steady streams of voice and audio,” says Suke Jawanda, Chief Marketing Officer of the Bluetooth Special Interest Group (SIG), which owns and licenses Bluetooth technology. “Bluetooth Smart is about sending packets of bits and data to applications.”
Life changing
Healthcare is frequently cited as one area that hasn’t witnessed the radical transformations underway elsewhere as a result of the ongoing digital mobile revolution. The growth of novel personal medical sensing technologies, many of which use Bluetooth, could soon change this. Earlier this year, a Silicon Valley-based start-up called Scanadu sought to raise $100,000 on the crowd-funding site IndieGoGo. In fact donors pledged over $1.6 million, making it the most funded project in the site’s history. The product description may have helped: the Scanadu Scout is perhaps best described as something approaching a real version of the medical tricorder wielded by Star Trek doctor Leonard “Bones” McCoy.
Placing the cookie-sized device to your forehead for 10 seconds provides stats on your heart rate, blood pressure, core body and skin temperature, respiratory rate, blood oxygen levels, blood pressure and emotional stress levels. This data is transmitted via Bluetooth to users’ phones or tablets.
"With recent advances in technology such as Bluetooth, we are now able to build medical devices that weren't possible just a decade ago…. at an affordable price [using] existing infrastructure of smart phone telecoms” says Scanadu’s CEO Walter de Brouwer. “For people who live far from hospitals, in places like Africa, this could be life changing.”
On the other side of the Atlantic, a group of researchers at the Ecole Polytechnique Federale de Lausanne, Switzerland, is working on BlueCell, a half inch-long device that, once embedded under the skin monitors substances in the blood such as glucose and cholesterol so that chronic diseases like diabetes or the effects of treatments such as chemotherapy can be monitored. The raw medical data, which is sent wirelessly via Bluetooth to an Android app, can be forwarded automatically to doctors. BlueCell is still a few years from commercialisation.
“We chose Bluetooth because of its wide distribution in consumer devices,” says Jacopo Olivo, one of the researchers. “It’s an interesting way that Bluetooth can interact with the biotech industry.”
Other personal health sensors that use Bluetooth include the Cardiopad, an electrocardiography (ECG) machine developed to monitor heart activity in patients in remote areas of Cameroon, and Monobaby, a device being developed to prevent Sudden Infant Death Syndrome, also known as cot death, using an accelerometer attached to baby clothing.
Growing signal
Bluetooth can improve health prospects beyond humans too. Flower Power, a device due to be launched towards the end of this year by Paris-based wireless tech company Parrot, measures sunlight, soil moisture, temperature and nutrient levels in plants, and sends that information directly to an iPad app via Bluetooth.
By cross-checking this data against a database, the app provides information about the health of plants, when and how much to water them, and whether they should be moved to change sunlight levels.
Flower Power and related technologies could be vital in developing countries with dry climates. Sensors could be linked via Bluetooth to sprinkler systems to automatically optimise moisture levels. The ability to use just the right amounts of water and fertiliser to produce a good harvest without wasting resources can improve crop yields and rural incomes.
Bluetooth is also being used to help those in agriculture in other ways. Kenyan mobile tech company Virtual City has developed AgriManagr, an app designed to speed up and automate the flow of information and reduce costs for farming businesses. Small, rural tea farmers in Kenya, for example, complain that unscrupulous buyers routinely under-weigh their produce by 10-20%. Using AgriManagr, electronic scales are used to transmit the weight of produce via Bluetooth to a mobile phone which records this in farmers’ accounts on a cloud-based server. Hard copy receipts are also printed out.
“When [payments] used to be a paper-based system, farmers would get conned on the weight,” says Virtual City chief executive John Waibochi. “Buyers would tamper with the weight scale.” Going digital and printing receipts “cuts out fraud… and increases the value to farmers 9-13%,” he adds.
This system could of course be done without Bluetooth, but being wireless makes it easier. “Out in the rural areas, cables would not survive,” claims Waibochi. “And I need my devices to go to sleep immediately after they are used. With Bluetooth, our devices do that, and can work for 12 hours without electricity.”
Bluetooth can also provide new ways of communicating in rural settings where internet access is unavailable or out of reach for the poor. Gary Marsden, a computer scientist at the University of Cape Town, developed Big Board, an electronic notice board that disseminates information wirelessly and for free.
The system displays a series of icons representing information on various topics on a screen. Users take a picture of an icon they are interested in with their phone and send it via Bluetooth to a nearby device which sends them the information they want. Files can be pictures, text, video or audio. Potential applications include distributing information on health, job offers or entertainment.
In a pilot project Big Board was used to inform voters about the manifestos of politicians standing in the 2007 Kenyan presidential election. People could take a photo of a candidate and receive an MP3 of that person speaking. Marsden is currently working with NGOs and government agencies to develop new applications.
He also developed Com-Me, a collection of hardware and software components to help people with limited access to electricity and the internet create and share content. This includes a solar-powered phone charging station and a Bluetooth-based local version of Dropbox, designed to allow off-grid communities to share and store information in a variety of formats.
Bluetooth Smart, like its older sibling, may be a relatively straightforward radio wave-based transmission technology. But as we devise more and more ways to benefit from ever greater connectivity between the people, other living organisms, objects and our environments, it seems to be getting smarter by the day.
