Anti-abduction system and method
First Claim
1. An anti-abduction system comprising:
- (a) a master transceiver, which may be proximal to a monitor;
(b) a slave transceiver, which may be attached to a potential abductee;
wherein said master transceiver communicates with said slave transceiver utilizing varying degrees of power transmission to determine the spatial proximity of said slave to said master;
said master transceiver is notified when communication with said slave transceiver is disrupted;
said slave transceiver has a unique identification code which is broadcasted at high power if said communication is disrupted with said master transceiver.

Abstract
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.

11. An anti-abduction method comprising:
-
(1) a master transceiver communicating with a slave transceiver at low power with limited communication distance;
(2) it said slave transceiver responds, said master transceiver assuming said slave is proximal to said master and in no danger;
(3) if said slave responds to said master, proceeding to step (5). (4) otherwise, said master assumes said slave is in danger and said master attempts to communicate with said slave, then proceeds to step (6);
(5) if said slave issues a panic alert, then proceeding to step (6), otherwise proceeding to step (1);
(6) said slave communicating to said master and/or law enforcement at high transmission power with identification to indicate an alert status, and then proceeding to step (1). - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
