Fujitsu, NICT create indoor navigation for the blind using ultrawideband, Android phones, kind hearts
There's no shortage of navigation outdoors, and even a little bit of help indoors, but there's been precious little aid for the blind indoors -- leaving them little choice but to move cautiously or get outside help. Fujitsu and Japan's NICT have crafted a system that gives the sightless a greater level of autonomy inside through ultrawideband-based impulse radio. A grid of UWB radios positioned around a room gauge the distances between each other and transmit the data to a PC, which then talks to the traveler's Android phone. The device then gives spoken directions based on a 12-o'clock system and far subtler distances than GPS can manage: the positioning is accurate to within a foot. While the indoors navigation is only just getting a demo this week, it's already being refined to detect objects in the room as well as to help even the fully sighted. If Fujitsu and NICT have their way, buildings ranging from hospitals to malls will have their own turn-by-turn navigation. For some, the freedom of movement could be a life-changer.
Flexible wireless charging sheet could eventually turn your skinny jeans into power pants (video)
If you haven't already heard, wireless charging is all the rage -- cars, cameras, and, of course, cellphones have all benefited from the burgeoning technology. Now a team of researchers at Japan's National Institute of Information and Communications Technology (NICT) are showing off a 2D power transmission system that could turn your pockets into wireless charging stations. According to its creators, "When a 2.4GHz high frequency signal is transmitted through the sheet, it becomes a wireless conductive object." Electromagnetic waves are captured in the sheet and can be concentrated in particular areas, allowing for individual activation of multiple devices, and thus increasing efficiency -- systems like Qi currently require a dedicated transmitter per device. The NICT says the power it provides is still relatively weak -- about 1W -- but it has plans to eventually bring the technology to soft fabrics. So maybe that Snuggie charging station you've been dreaming of isn't so impractical after all.
Wearable ECG uses patient's posture for encryption, transmits data over Body Area Network
Though its fun to think of the Body Area Network as another way for cheap employers to get out of paying for properly wiring your workspace, the most obvious uses for this technology would seem to be in the realm of health care. To this end, the National Institute of Information and Communications Technology (NICT) in Japan has developed an ECG that can be worn 24 hours a day, wirelessly transmitting electrocardiographic data as well as measuring changes in body surface temperature and posture. The data can even be transmitted securely using cryptographic keys dynamically generated by the patient's posture and biological data (which are unique to each user). We'll let you guys ponder the cypherpunk ramifications of this technology in the comments -- and be sure to check out the additional pic we have for you after the break.
