Passive entry sensor system
First Claim
1. A passive entry sensor system for use with a keyless access control system, comprising:
- a handle for opening a door; and
a sensor comprising an electromagnetic radiation emitter for emitting a beam of electromagnetic radiation and an electromagnetic radiation detector for detecting the electromagnetic radiation beam, wherein said emitter and said detector are arranged in said handle such that, when said handle is attached to the door, said sensor can detect at least a partial modification or interruption of the beam caused by a user actuating the handle to open the door.

Abstract
Passive entry sensor systems and associated sensors are disclosed. The system sensor is arranged in the handle of a door or directly mounted to the door skin. When mounted in the handle, the sensor provides an electromagnetic radiation beam transmitted either along the length of the handle between opposite ends thereof or between the handle and the door so that the beam can be at least partially interrupted or modified by a user actuating the handle. When mounted directly to the door skin, the sensor provides an electromagnetic radiation beam transmitted between the handle and the door. The sensor system includes indicators for indicating system status to the user, back-up switches for detecting a pull on the handle, locking switches for activation by a user to lock or unlock the door and backlight and ground light lighting.

14. A passive entry sensor system for use with a keyless access system comprising:
-
at least one light source, said light source being operable by a control module to indicate one or more system modes and/or to provide lighting in the vicinity of the handle; and
a sensor comprising an electromagnetic radiation emitter for emitting a beam of electromagnetic radiation and an electromagnetic radiation detector for detecting the beam of electromagnetic radiation, wherein said emitter and detector are arranged such that, when said handle is attached to the door, said sensor can detect at least a partial modification or interruption of the beam caused by a user actuating the handle to open the door. - View Dependent Claims (15, 16)

17. A passive entry sensor for use in a keyless access system comprising:
-
an electromagnetic radiation emitter for transmitting a beam of electromagnetic radiation;
an electromagnetic radiation detector for detecting the electromagnetic radiation beam reflected from a surface;
a lens protector for protecting said emitter and detector; and
a housing for housing said emitter, detector, and lens protector, wherein said housing is adapted to be mountable directly to the skin of a door beneath a door handle such that said sensor can detect at least a partial modification or interruption of the beam caused by a user actuating the handle to open the door. - View Dependent Claims (18, 19, 20)
