Anti-abduction system and method

摘要

An anti-abduction system and method is disclosed which utilizes a radio frequency transceiver attached to a slave to communicate with a corresponding master transceiver to detect and prevent abductions, which may be advantageously applied to situations in which child abduction is a possibility. The disclosed system and method utilizes communication protocols to notify the master of the proximal locality of the slave unit and any spatial deviation of the slave from the master. Utilization of varying strength transceiver signaling between the master and slave permits the distance between the master and slave to be approximated. Additionally, the slave may contain an optional heartbeat monitor to detect and report situations in which the device is removed from the potential abduction victim. The present invention may be generally targeted towards preventing child abductions, but has applications as an anti-terrorist device in preventing kidnappings of political persons and other innocents by terrorist groups and the like.
