Abstract: An electronic lock includes an interior subassembly including a manual turnpiece, a control circuit, and a motor actuatable by the control circuit, and an exterior subassembly including a facial authentication circuit operatively connected to the control circuit. The electronic lock includes a latch operatively connected to the interior subassembly, the latch being engageable by the manual turnpiece or the motor to move the electronic lock between a locked state and an unlocked state. The facial authentication circuit includes at least one camera and is configured to generate an authentication signal to the control circuit, and wherein, at least in part in response to the authentication signal, the control circuit is configured to actuate the motor to move the electronic lock between the locked state and the unlocked state.

Abstract: Backlighting is provided for an LCD-TV display by directing light from a source into an open end of a cylindrical drum, the other end of which is closed. The drum has a highly reflective inside surface and a beam is directed through an orifice in the cylindrical wall of the drum. A plurality of optical fibers are positioned with one end of each on a circle coaxial with the drum and the other end of each attached along one edge of the panel to which backlighting is provided. The drum, and thus the beam, is rotated about its axis at constant angular velocity, providing light sequentially to each of the fibers with resulting scrolling of the light across the panel behind the LCD array.
