System for automatically moving access barriers and methods for using the same
First Claim
1. 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 comprising a processor and a transponder in communication with said controller via said transceiver, said transponder communicating operational signals with said beacon transceiver based upon a position of said proximity device with respect to said beacon transceiver, wherein said controller is programmed to identify said proximity device, and wherein said beacon transceiver periodically emits a beacon signal having at least two power level signals, each said power level signal having an effective range, and each said power level signal emitted in a predetermined sequence to determine a position state of said transponder and wherein said controller monitors a number of said operational signals returned from said transponder at the at least two power levels and changes said power level signal based upon said number of said operational signals returned so as to control the position of said access barrier based upon a change in said position state and the position of said access barrier.

Abstract
An operator system and related methods for automatically controlling access barriers including a controller associated with at least one access barrier and a transceiver associated with the controller for transmitting and receiving operational signals. The system also includes at least one proximity device capable of communicating operational signals with the transceiver based upon a position of the proximity device with respect to the barrier, wherein the controller monitors the operational signals and controls the position of the access barrier based upon the operation signals. Such a system allows for hands-free operation of the access barrier. Ground loop detectors and a global positioning system may also be incorporated into the system. And the system may be used to control the directional flow of traffic on a one-way road.
