METHOD AND SYSTEM FOR POSITIONAL FINDING USING RF, CONTINUOUS AND/OR COMBINED MOVEMENT
First Claim
1. A system for locating an object, comprising:
- a Master Unit having a first RF transceiver and adapted to interface to a Tag to measure distance to the Tag, wherein the Tag includes a second RF transceiver;
the Master Unit having a first input from which it can derive its current position;
the Tag having a second input from which it can determine a distance the Tag has traveled;
the Master Unit adapted to transmitting instructions to the Tag for movement in a predetermined direction;
the Master Unit being adapted to receiving information from the Tag relating to the Tag'"'"'s movement;
the Tag being adapted to receiving instructions for movement in the predetermined direction;
the Tag being adapted to transmitting the information related to its movement to the Master Unit;
the Master Unit adapted to determine distance to the Tag after the movement of the Tag; and
the Master Unit adapted to determine position of the Tag after the movement of the Tag.

Abstract
A system for determining location of an object, the system including a Master Unit having an RF transceiver and adapted to measure distance to the Tag. The Master Unit has a first input from which it can derive its current position. The Master Unit transmits instructions to the Tag for movement in a predetermined direction. The Master Unit measures distance to the Tag after the movement in the predetermined direction. The Master Unit determines position of the Tag after the movement in the predetermined direction. The Tag can include a compass, a pedometer, and optionally an accelerometer, a solid-state gyroscope, an altimeter inputs for determining its current position by the Master Unit. The Master can optionally include a compass as well as a pedometer, an altimeter, an accelerometer, a solid-state gyroscope, an altimeter and a GPS receiver. Also, the Tag movement does not have to follow the Master'"'"'s direction. However, the Master Unit still will be able to determine the Tag location(s). Also, the roles of the Master Unit and Tag can be reversed.
