Power conserving mobile transmitter used with an automated barrier operating system
First Claim
1. An operator system for automatically controlling access barriers based on movement of a carrying device, comprising:
- an operator controller associated with an access barrier;
a base receiver associated with said base controller;
a mobile transmitter including an activity sensor configured to monitor movement in at least one axis of movement and a mobile emitter, said mobile transmitter configured to automatically emit from said mobile emitter a mobile open signal and a mobile close signal containing at least one warning data bit that is placed in a set state when said activity sensor first detects a change in movement of said mobile transmitter, wherein said base receiver receives said mobile open signal and said mobile close signal and said operator controller resets a last process variable when said at least one warning bit is received.

Abstract
An operator system for automatically controlling access barriers based on movement of a carrying device. The system consists of an operator controller associated with an access barrier, a base receiver associated with the base controller, and a mobile transmitter that includes an activity sensor configured to monitor movement in at least one axis of movement and a mobile emitter. The mobile transmitter is configured to automatically emit from the mobile emitter a mobile open signal and a mobile close signal containing at least one warning data bit that is placed in a set state when the activity sensor first detects a change in movement of the mobile transmitter. The base receiver receives the mobile open signal and mobile close signal, and the operator controller resets a last process variable when the at least one warning bit is received.

9. A method for automatically controlling at least one access barrier comprising:
-
providing a mobile transmitter having an activity sensor and a mobile emitter, said mobile emitter configured to automatically generate a mobile open signal and a mobile close signal when said activity sensor detects movement of said mobile transmitter; providing an operator controller associated with a base receiver and an access barrier, said base receiver receiving said mobile open signal and said mobile close signal; setting at least one warning bit that is included in said mobile open signal and said mobile close signal when said activity sensor first detects a change in movement of said mobile transmitter; and moving said access barrier by said operator controller depending upon a status of said at least one warning bit and receipt of said mobile open signal or loss of said mobile close signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
