Patent ID: 7110880

Claim:
An arrangement for transferring information between a vehicle and at least one transmitter separate from the vehicle, each of the at least one transmitter transmitting radio frequency waves containing positional information about the transmitter, information necessitated by the information transferring arrangement and additional information of potential interest for operation of the vehicle, comprising: an antenna mounted on the vehicle and capable of receiving radio frequency waves emitted by the transmitter and containing information; a position determining device for determining the position of the vehicle; and a processor coupled to said antenna and said position determining device and arranged to analyze the waves received by said antenna, determine whether any received waves contain information of interest for operation of the vehicle based on the vehicle's position as determined by said position determining device, and extract the information of interest only from the received waves determined to contain information of interest, said processor being arranged to extract only the positional information and the information necessitated by the information transferring arrangement from all received waves and analyze the positional information to determine whether any received waves contain information of interest for operation of the vehicle and then extract additional information only from received waves determined to contain information of interest for operation of the vehicle.
