  • Patent number: 8886223
    Abstract: A system for determining location of an object including a Master Unit having an RF transceiver and adapted to measure distance to a Tag. The Master Unit has a first input from which it can derive its current position, transmits instructions to the Tag for movement in a predetermined direction, measures distance to the Tag after the movement in the predetermined direction, and determines position of the Tag after the movement in the predetermined direction. The Tag and Master Unit can include a compass, a pedometer, an accelerometer, a solid-state gyroscope, an altimeter inputs for determining its current position by the Master Unit. The Master Unit can optionally include a GPS receiver. The Tag movement does not have to follow the Master Unit's direction, but the Master Unit will still be able to determine the Tag location(s). The roles of the Master Unit and Tag can be reversed.

  • Patent number: 7822424
    Abstract: A wireless system (20) and method for determining the location of a fixed or mobile target (31, 32, 33 . . . ) configured to have a transponder (31, 64) on the target (31, 32, 33 . . . ), a transceiver (21, 44) monitoring the target location, communicating between the transponder (31, 64) and transceiver (21, 44), and a processor (40) for finding the target by virtual triangulation based on values of received position information. The processor (40) is configured to determine virtual triangulation based on successive values of the position information using at least three points (P1, P2 and P3) of the transponder (31) respective of the transceiver (21).

  • Patent number: 7760132
    Abstract: The present invention is an RF system and methods for finding a target T in three dimensional space configured to have a transponder disposed on the target T, a monitoring unit configured as a transceiver for determining or monitoring the location of the target T and an RF wireless communication system configured with a processor to repeatedly determine position, communication and other values between the transponder and monitoring unit and so as to generate a measured distance between units in three dimensional space by determining the measured distance of the target T by a spherical virtual triangulation relationship when successive values of said position information has a predetermined logical relationship relative to said previous values between said monitoring unit and transponder and/or slave unit disposed on the target T.
