Abstract

Claims (15)

1. An apparatus, comprising:

a gate operable to move between a closed position and an open position;

a rotating magnet coupled with the gate;

two fixed sensors that provide signals based on a position of the rotating magnet; and

a controller coupled with the two fixed sensors, the controller is operable to determine a position of the gate based on signals from the two fixed sensors and to determine whether a motor operable to move the gate is running;

wherein the controller determines a tampering event responsive to determining the position of the gate has changed based on signals from the two fixed sensors when the motor is not running; and

the controller is operable to take corrective action responsive to determining the tampering event.

2. The apparatus set forth in claim 1 , further comprising the controller is operable to disable tampering detection responsive to a command to activate the gate motor.

3. The apparatus set forth in claim 2 , further comprising:

the controller is operable to determine whether the gate returned to the closed position after gate operation has completed; and

the controller is operable to activate tampering detection responsive to the gate successfully returning to the closed position.

4. The apparatus set forth in claim 2 , further comprising:

the controller is operable to determine whether the gate returned to the closed position after gate operation has completed; and

the controller is operable to take corrective action responsive to determining the gate did not return to the closed position.

5. The apparatus set forth in claim 4 , the corrective action comprises waiting for an initialization command from a higher layer processor.
