Abstract
A keyless access sensor system for use with a keyless access control mechanism (KACM) is described for controlling the operation of a locking device. The KACM receives a signal from a sensor device for keyless access to create a first output signal before the user has begun any action on the handle in order to open the door. The first output signal is sent to a general processor, which initiates a recognition process and, after recognition of the authorized user the processor then generates an unlocking signal which unlocks the locking device before the authorized user will have fully accomplished the action of opening the door. Thus the authorized user is allowed to open the door without any specific un-ergonomic and time-consuming additional action to the simple action of actuating the handle to open the door. The second signal is generated by a device, such as a fob, card or the like, carrying a unique digital or analog identification in response to RF or IR interrogation from the general processor after it receives the output signal from the sensor device for keyless access.
