SYSTEM AND METHOD FOR WIRELESS DETECTION AND MEASUREMENT OF A SUBJECT RISING FROM REST

A method for wireless detection of a subject rising from a rest state includes producing transmitted wireless signals from one or more transmitting antennas, receiving reflected wireless signals at one or more receiving antennas, and processing the reflected wireless signals in a computer. The compu...

More Information
Summary:A method for wireless detection of a subject rising from a rest state includes producing transmitted wireless signals from one or more transmitting antennas, receiving reflected wireless signals at one or more receiving antennas, and processing the reflected wireless signals in a computer. The computer iteratively aligns candidate trajectories with a template trajectory until the current and previous template trajectories are within a predetermined distance from each other. A final template trajectory is used to determine a lying-down surface exit initiation area, a lying-down surface exit initiation area exit time, a TUG plane or radius entry time, and a TUG time.
