ABSTRACT:
A mobile transponder for vehicles with an optical indicator providing information concerning the direction from the transponder to a vehicle. A plurality of antennas provide three-dimensional directional characteristics in order to recognize the signal from the vehicle and to provide a directed output. An evaluation circuit analyzes the signal from the antenna and provides output information concerning the direction and location of the vehicle in relationship to the transponder. This information is displayed on the transponder regardless of the orientation of the transponder.
