Patent ID: 8223073

Claim:
An apparatus for providing a determination of direction between an object and a user comprising: a first antenna having a first gain pattern; a second antenna having a second gain pattern different than the first gain pattern of the first antenna, the first and second antenna being situated at or near a first location associated with either the user or object; a third antenna for transmitting a location signal, the third antenna situated at a second location associated with the other one of either the user or object; a circuit coupled to the first antenna and second antenna to determine field strengths of the location signal received at the first and second antennas and to determine by comparison of the received location signal at the first and second antennas a probable relative direction between the user and the object, where the first and second antennas are included within a first direction finding device and further comprising a second direction finding device communicated to the first direction finding device so that the second direction finding device is arranged and configured to determine the relative probable direction of the first direction finding device.
