发明名称 PERSONNEL LOCATION MONITORING SYSTEM AND METHOD
摘要 A system and method for monitoring the location of an individual includes (a) a band attached to the individual that has a pressure actuated tamper indicator and (b) a monitoring/tracking unit that may be used to both monitor whether the individual has left a predetermined area and to provide an indication of the direction to the individual. The band may include a latch that applies pressure to a pressure sensitive pad when the latch is closed. When the latch is opened, pressure is removed and the transmitter may provide an indication that the band has been removed. The monitoring/tracking unit may include directional and omnidirectional antennae and a self-contained power source for portable operation of the unit.
