摘要： The invention provides a determination of direction to a remote object which omnidirectionally transmits a signal. The invention includes a handheld directional and omnidirectional antenna at a user's location and a handheld circuit coupled to the antennas to determine field strengths of the signal received from the remote object by the two antennas. A comparison of the received signals at the antennas during a sweep a field of observation is made and a probable direction of the remote object relative to the user's location is selected from the data sweep. The apparatus may further comprise a digital compass which generates a compass heading corresponding to each direction in which the directional antenna is pointed. The circuit stores field strength data by compass heading and averages the field strength data according to a predetermined protocol over compass headings.

摘要： An apparatus and method for adding functionality to wireless mobile handsets, mobile phones, smart phones and other portable wireless devices which allows the devices to report the direction and distance of a wireless beacon that is attached to objects in need of being tracked or found. An external protective case is coupled to an existing mobile handset which comprises a plurality of directional antennas and associated RF circuitry. The electronics of the case are coupled to the electronics of the handset and with assistance of downloaded software of an associated application program, the handset may used to track or find one more beacons that have been previously paired with it.
