  • Position detection
    Patent number: 8164444
    Abstract: Embodiments of the present disclosure relate to methods, devices, and systems for position detections of an individual. One method to detect a position of an individual includes creating a zone map by mapping locations of a number of fixed sensors in a zone and signal strengths of a number of communications between the fixed sensors and at least two wireless access points. The method also includes determining signal strength values of a number of communications between the wireless access points and a mobile sensor and comparing the signal strength values of the number of communications between at least two wireless access points and the mobile sensor with the zone map to determine the mobile sensor's position in relation to the zone.
