Apparatus and method for tracking the location and position of an individual
First Claim
1. A position and location indicating apparatus for locating an individual comprising:
- a mobile target device sized for attachment to said individual to be tracked, said target device having circuits for transmitting and receiving radio frequency signals, a mobile monitor device, said monitor including a circuit capable of providing bi-directional communication with a mobile target device, a processing element associated with said monitor device, said processing element being capable of calculating relative distance and direction from said mobile monitoring device to said mobile target device based upon information derived from the communication between the mobile target device and the mobile monitoring device, and a broadcast element associated with said monitor device, said broadcast element capable of providing relative distance and direction information between a mobile monitor and a mobile target to a mobile monitor operator.

Abstract
An apparatus and method and provided for tracking the location and direction of an individual utilizing a direct radio frequency link between a mobile target and a mobile monitor. The apparatus and method utilize a mobile target device which may be affixed to an individual to be tracked utilizing a secure attachment mechanism. A mobile monitor device in bi-directional communication with the mobile target device is additionally provided. This radio frequency communication is encrypted in nature, thereby preventing unauthorized tracking of an individual by an non-intended third party. The mobile monitor device broadcasts the relative distance and direction between the mobile monitor device and mobile target device to a mobile monitor operator. A Bluetooth® enabled microprocessor may be utilized in transmitting and receiving this encrypted signal. Based upon data derived from the radio frequency information received by a mobile monitor, a relative distance and direction from a mobile monitor to a mobile target may be computed.

25. A method for tracking the location an individual, comprising the steps of:
-
providing a mobile target device on the individual to be tracked, providing a mobile monitor device capable of communication with said mobile target device, requesting the transmission of a data packet from said mobile target device by said mobile monitor, transmitting a data packet from said mobile target via a radio frequency link between said mobile target device and said mobile monitor device, receiving and processing said data packet by said mobile monitor device such that distance and direction from said mobile monitor device to said mobile target device can be computed based upon information derived from the communication between said mobile target device and said mobile monitor device, and broadcasting the relative distance from said mobile monitor device to said mobile target device to a mobile monitor device operator. - View Dependent Claims (26, 27, 28, 29)
