Patent ID: RE39170

Claim:
A security device able to control movement of a vehicle to and from a designated parking area comprising: a barrier capable of movement between a first position for preventing movement of a vehicle past the barrier and a second position for allowing movement of a vehicle past the barrier; a controller for selectively controlling operation of the barrier between the first and second positions; a driver for effecting movement of the barrier from the second position to the first position in response to a selective operation of the controller; and an arming means for arming the driver for effecting movement of the barrier from the second position to the first position in response to selective operation of the controller when the arming means is in the armed condition, said arming means being movable from an unarmed position to the armed position to arm the driver by movement of the vehicle over the security device, wherein a first operation of the controller causes the driver to move the barrier from the second position to the first position substantially simultaneously with the arming means moving from the armed position to the unarmed position thereby disarming the arming means, and a second operation of the controller allows the barrier to move from the first position to the second position while the arming means remains in the unarmed position, and wherein movement of the vehicle over the security device when the arming means is in the unarmed position moves the barrier arms the driver for future movement of the barrier from the second position to the first position.
