Patent ID: 7310043

Claim:
An operator system for automatically controlling access barriers, comprising a controller associated with at least one access barrier; at least one beacon transceiver associated with said controller for transmitting and receiving operational signals; and at least one proximity device adapted to be associated with a powered carrying device, wherein said proximity device comprises a transponder; a processor connected to said transponder, said processor in communication with said controller via said at least one beacon transceiver; and a plurality of wire leads connected to said processor, wherein said plurality of leads are connectable to a power supply of the powered carrying device, and wherein said processor detects when the powered carrying device is either in an on condition or an off condition; said at least one proximity device capable of communicating operational signals with said at least one beacon transceiver, said operational signals based upon an operational status of the powered carrying device and a position of said proximity device with respect to the barrier, the position of said proximity device determined by the successful receipt of a predetermined number of power level signals communicated between said beacon transceiver and said proximity device, wherein said controller monitors said operational signals and said power level signals and controls the position of the access barrier based upon said operational signals and said power level signals and whether the powered carrying device is an on or off condition.
