Abstract: A passive tracking system is provided with a plurality of ultrawideband (UWB) receivers that is asynchronous with respect to a UWB transmitter. A geometry of the tracking system may utilize a plurality of clusters with each cluster comprising a plurality of antennas. Time Difference of Arrival (TDOA) may be determined for the antennas in each cluster and utilized to determine Angle of Arrival (AOA) based on a far field assumption regarding the geometry. Parallel software communication sockets may be established with each of the plurality of UWB receivers. Transfer of waveform data may be processed by alternately receiving packets of waveform data from each UWB receiver. Cross Correlation Peak Detection (CCPD) is utilized to estimate TDOA information to reduce errors in a noisy, multipath environment.

Abstract: The Electrical Heat and Vibrating Device is a lightweight, portable, completely self-contained low voltage, and self-administered therapeutic apparatus. More particularly, this invention gives the wearer or user comforting sensations to facilitate a temporary reduction in joint stiffness, joint pain, and joint discomfort, within the human body.

Abstract: The Electrical Heat And Vibrating Glove is a fully leather enclosed glove which combines the application of both gentle heat and gentle massage to give the wearer or user comforting sensations to facilitate a reduction in hand stiffness, joint pain and discomfort in the below-wrist area. Configured in left and right hand versions, the glove operates on electricity obtained from conventional wall sockets(heating element) and a 2-AA battery powered massage motor. Additionally, the glove has a portability feature in that the heating element can be alternately powered by a 16 volt transformer. The heat is manually regulated by a top-side heat control dial, and the strength of the massage sensation is governed by the 2-speed battery-powered massage motor. The glove is open at the fingertips so that redness and skin irritation is easily detectible; this also adds a sporty look to the glove.
