Microsoft granted patent for wearable EMG device
Those muscle spasms? They're now good for something. Okay, so Microsoft's just-granted patent for a wearable EMG device doesn't really thrive off of involuntary twitching and such, but it does use your movements to control your smartphone, notebook and other gadgets. The "Wearable Electromyography-Based Controller," which we first glimpsed back in 2010, uses sensors to interpret the electrical signals generated by a user's muscles, and then communicates with the wearer's computer via a wireless (or wired) connection. Redmond envisions the wearable device in various incarnations: as an armband equipped with sensors, a shirt, eyeglasses and even nodes attached directly to the user's body. In the armband example, motion control could be used to interact with a PMP while the user is jogging. No matter the setup, a calibration process allows the system to locate specific sensors and collect information based on specific gestures or movements, which means playing Guitar Hero with only an air guitar may someday be a reality after all.
Bluetooth SIG forms new working group focused on fitness gadgets
We've been seeing Bluetooth make more and more inroads into fitness gadgets as of late, and it looks like the Bluetooth Special Interest Group is intent on seeing that trend continue. It announced the formation of a new Sports and Fitness Working Group today, which will be tasked with increasing the interoperability between wearable gadgets and other sensors and so-called "hub" devices like smartphones, TVs and gym equipment. That's a fairly natural fit for Bluetooth now, but it's taken until Bluetooth 4.0 for the standard to really emerge as a viable alternative to lower-power options like ANT+ (now commonly used in heart rate monitors and the like).
Philips tech enables wearable light therapy device
When Philips was looking for medical applications for their flexible Ledfoil disks, they were probably hoping to find a market of more than 200 people, but luckily for sufferers of the rare Crigler-Najjar syndrome, they happened to come across Dutch student Philomeen Engels. Engels, a recent graduate of the Delft University of Technology, had the idea of creating a wearable light therapy device using the Philips tech, which would free Crigler-Najjar patients -- whose bodies cannot break down the potentially lethal red blood cell by-product called bilirubine -- from the 12 hours they must spend inside converted sunbeds each day. The device, known as the Ledwrap, contains twelve Ledfoils between two layers of cloth and can act as either a sleeping bag or a rather bulky bodysuit for more freedom of movement -- well, as much movement as an extension cord allows, since the LEDs require too much juice to run on batteries. Engels hopes to have the first Ledwraps on the market within a year, although that may be a bit optimistic, as the prototype has yet to undergo the rather non-trivial task of actual medical testing.
