ABSTRACT:
A parking stall monitor located adjacent a restricted use parking stall detects vehicle presence in the parking stall and activates an alarm to provide a warning in response thereto. A disarm/arm circuit associated with the monitor generates a coded input in response to receipt of an identification signal from an authorized user, thereby to disarm either the detector or the alarm to enable the vehicle of the authorized user to occupy the parking stall without a warning being provided. Subsequently, when the authorized user is ready to leave the parking stall, receipt by the disarm/arm circuit of another identification signal, or removal of the initial identification signal, causes the monitor to rearm. The identification signal may be produced nonautomatically or automatically, either actively or passively, and the capability of originating this signal serves to distinguish a selected group of authorized users from those not permitted to use the stall.
