Abstract: A system and method of light bulb and fixture comprising an occupancy sensor, a light meter, and an on/off circuit switch is used to manage the lighting use base on the sensing the presence of people and area lighting condition. The occupancy sensor, light meter, an on-off circuit switch, and a regulator are incorporated into the light bulb or fixture for easy replacement and no need of re-wiring or major fixture change.

Abstract: A low power consumption semiconductor memory circuit that includes a memory core (e.g., a ROM core) with a plurality of intersecting bit lines and word lines, as well as a plurality of memory cells at predetermined intersections of the bit and word lines. The low power consumption semiconductor memory circuit also includes a pre-discharge circuit, a multiplexer circuit (MUX), and a sense amplifier circuit. The pre-discharge circuit is electrically connected to the memory core and configured for discharging each of the bit lines to ground (GND). The MUX circuit is electrically connected to the pre-discharge circuit and configured for selecting at least one of the bit lines as its input. Furthermore, the sense amplifier circuit is configured for sensing an electrical state of an output node of the MUX circuit and, in one embodiment, includes a current generator circuit configured to charge a pre-discharged bit line during a READ operation.

Abstract: A microelectronic cell includes a semiconductor substrate, an active area formed in the substrate, a gate formed in the active area, and a first contact formed in the active area. The contact has a width D perpendicular to a reference axis defined in the active area, and is spaced from the reference axis by a minimum spacing E. The gate includes a first section which extends substantially parallel to the reference axis, the first contact being disposed between the first section and said reference axis, the first section being spaced from the first contact by a minimum spacing A; a second section which extends substantially parallel to and is spaced from said reference axis by a minimum spacing C<(A+D+E), the second section being spaced from the first section along said reference axis; and a third section which extends at an angle to the reference axis and joins adjacent ends of the first and second sections.
