System and methods for automatically moving access barriers initiated by mobile transmitter devices
First Claim
1. An operator system for automatically controlling access barriers used to enclose a carrying device, comprising:
- a base controller associated with at least one access barrier;
at least one base receiver associated with said base controller; and
at least one mobile transmitter transmitting an open signal and a close signal, wherein said transmitter monitors a change in position of the carrying device and transmits said close signal when said mobile transmitter detects that the position of the carrying device has changed a predetermined amount, and wherein said mobile transmitter transmits said open signal automatically, said base controller selectively generating barrier movement commands depending upon when said open and close signals are received by said at least one base receiver.

Abstract
An operator system provides a mobile transmitter configured to communicate with a base operator to automatically open and close an access barrier based on the position of a carrying device that maintains the mobile transmitter. The mobile transmitter periodically transmits a mobile open signal as it moves away from the reception range of the base operator until that signal is lost. When the base operator again receives the open signal, the access barrier is automatically opened. In addition, the mobile transmitter is configured to monitor the change in position of the carrying device as it moves away from the enclosure. When the angular and/or linear position of the carrying device changes by an amount greater than a predetermined threshold, the mobile transmitter automatically transmits a mobile close signal to the base operator to close the access barrier.

17. A method of automatically closing and opening an access barrier based on a change in position of a carrying device comprising:
-
automatically and periodically transmitting from a mobile transmitter maintained in the carrying device an open signal; determining whether a positional change of the carrying device exceeds a predetermined threshold value; transmitting from said transmitter a close signal if a change in a position of the carrying device exceeds said predetermined threshold value; receiving in a barrier operator that controls movement of the access barrier said open signal and said close signal; closing the barrier when said close signal is received and the access barrier is open; and opening said access barrier after receiving said open signal and the access barrier is closed, but only after not receiving said open signal for a predetermined period of time. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
