Abstract

Offender presence warning system comprises;

a tracking device securely attached to an offender limb, containing a GPS receiver and a wireless modem an RF transceiver designed to transmit at time interval RF signal. And a victim carry on RF transceiver device which receives offender tracking device transmitted signals when the offender is located within near proximity of a victim. The victim device in response to received RF transmitted signals from the tracking device, generates warning signal(s) to alert the victim the presence of an offender, and automatically transmits a RF signal(s) to the offender tracking device, which upon receipt of the RF signal generates alarm signal to warn the offender being too close to the victim, If the offender becomes non responsive, the offender tracking device transmits a signal to a monitoring station containing information to both the offender, and the victim unit ID along with GPS location information.

Claims

1. Offender presence warning system comprising;

a GPS tracking device securely attached to an offender limb which contains;

a battery or other power means to supply power to said GPS tracking device

a GPS receiver to receive GPS coordination signals from orbiting satellites, and

a cellular, satellite or a wireless RF module to establish long range communication with a monitoring station,

a processor and an RF transceiver designed to transmit at time interval uniquely coded low power short range RF signals, end

a victim carry on RF transceiver warning device having,

a battery or other power means to supply power to said victim unit,

a beeper and a vibrator,

a low power RF transceiver which is designed to receive said offender tracking device transmitted RF signals when said offender is located within near proximity of said victim, the victim carry on device processor in response to received RF transmitted signals from said offender GPS tracking device, said victim unit processor circuitry generates an audio/visual and or vibrating warning alarm signal(s) to alert the victim to the presence of an offender near by, and accordingly said victim device automatically transmits a uniquely coded RF signal to said offender tracking device, which upon receipt of said signal generates audio and or vibrating alarm signal to warn the offender being close to the victim and allow said offender a preset time to move away from said victim, If said offender becomes none responsive to said received warning signal(s), at a pre-determine time said offender GPS tracking device transmits violation signal to a monitoring station containing information both to said offender unit ID, and to said victim unit ID along with GPS location information of offender.

2. Offender presence warning system as claimed in claim 1 wherein said offender GPS tracking bracelet device utilizes two researchable batteries as power source, main researchable battery to provide constant power to said offender tracking device, GPS receiver, RF transceiver, cellular/satellite module, and to said processor circuitry, and utilizes a second removable rechargeable battery which is used for charging the main battery in remote locations.
