Texas Instruments has earned 825 U.S. patents through most of 2015, putting it on pace to perhaps slightly eclipse its 2014 totals. As the text cluster posted here shows our readers, much of TI’s recent R&D has focused on control signals, input signals and semiconductor devices… Short-range, low-power body area networks developed for medical purposes were featured by a pair of patent applications filed recently by Texas Instruments, including the innovation described within U.S. Patent Application No. 20150349839, entitled Ultra Wideband Modulation for Body Area Networks. It would protect a symbol modulation system having a symbol mapper configured to determine a time within a predetermined symbol transmission interval at which a transmission representative of the symbol will occur and then generate a single guard interval within the symbol transmission interval and positioned to terminate the symbol transmission interval. This body area network innovation establishes a physical layer which allows a receiver to identify and correct received data errors caused by channel issues. Physical layers in body area networks are also improved by the innovation discussed within U.S. Patent Application No. 20150350387, which is titled PHY Layer Options for Body Area Network (BAN) Devices. It claims a physical (PHY) layer method that involves performing body area network operations in a limited multipath environment using M-ary pre-shared keys (PSK), differential M-ary PSK or rotated differential M-ary PSK, and then transmitting BAN packets at a constant symbol rate. The use of physical layers to support BAN networking enables smarter medical devices, such as digital bandages that can measure and wirelessly transmit vital signs or pacemakers which can be fine-tuned after implantation.
