摘要:
An electronic lock includes a cylinder mounted for rotation in a shell and an electrically powered locking mechanism capable of selectively interfering with rotation of said cylinder. The locking mechanism is movable between a first position when the locking mechanism interferes with rotation of the cylinder and a second position when the cylinder is free to rotate. The lock includes a front facing nose (267) extending longitudinally along the axis of rotation of the cylinder, the nose having a front face (215) and sides extending rearward therefrom. The sides of the nose circumscribe the shape of the front face (215) and define an inner boundary of a groove about the face (215). The groove is for receiving the tip end of an electronic key. The lock includes electrical contacts (272, 294) on the front face (215) of the nose (267), with each contact for electrical connection with a respective electrical pin included in the key tip end.

An electronic locking system is provided wherein an electronic lock’s restriction of movement of a locked securing member (420), such as a door latch or bolt, can be selectively overridden from inside a locked enclosure by manual manipulation of a handle (426). The handle (426) moves the securing member (420) to open a locked barrier even though the electronic lock remains in a locked condition.

A portable sensing device for reading date codes comprises a thin, generally planar housing (10) of polygonal shape having a light source (28) and light sensor (30, 32, 34) at one of the corners thereof for reading data codes. The code reader contains a memory (42) not only capable of storing the sensed data codes for future access, but capable of being programmed. A multipurpose battery charger is provided which is capable of charging a plurality of the code readers simultaneously while receiving outputs from their memories (28) and inputting commands or programming. Although the output from each code reader is performed optically through coded pulsing of the light source (28), the input occurs through the battery charger terminals (64, 66), the charging current being delivered in coded pulses. Outputs from a plurality of code readers placed in a single charger unit occur sequentially in accordance with coded commands given by the charger.

An exceptionally thin, replaceable reader head (24) for an optical code reader (10) has a thin base (25) upon which are mounted both a light source (26) for illuminating the codes in an edgewise direction relative to the base, and a light sensor (28,30) for receiving light reflected from the codes also in an edgewise direction, the light sensor including an optical fiber (30) for contacting the codes. Detachable electrical connectors (26a and 28a) for the light source and light sensor, respectively, extend generally in edgewise directions opposite to the illuminating director (32) for connection through sockets (35,37) to the electrical circuits of the optical code reader (10). The base (25) of the reader head (24) contains deformable mounts (42,40) for fixedly connecting the light source and light sensor to the base, as well as fiber holding structure (46) for holding the optical fiber (30) in a predetermined position relative to the base. In order to reduce the requirement for precise alignment of the optical fiber (30) with the light sensor (28), the end portion (30a) of the optical fiber adjacent the light sensor (28) is of a varying cross-sectional area which increases gradually toward the end.

This disclosure provides methods, systems, and devices for communication of authentication information in an access control system. The authentication information may be transmitted to an electronic locking device configured to restrict access to an entry point of the access control system. In various embodiments, a smart device comprises a light-emitting diode (LED) and a wireless networking radio for exchanging access control information with a remote server. The smart device may receive information from the remote server that configures the LED to present authentication information as an optical signal. The electronic locking device may comprise a photodetector arranged to confront a user holding the smart device so as to receive an optical signal emitted by the smart device. According to various embodiments, the electronic locking device may be configured to respond to the authentication information conveyed by the optical signal by unlocking the entry point.
