Abstract: A fire-rated, poke-through floor fitting for use within a floor. The fitting has an electrical receptacle with electrical conductors or wires traveling the length of the fitting. The conductors have thermally activated conductor links. Upon exposure to excessive heat, the links stop the transfer of heat through the conductors.

Each pair of electrical outlets can be separately connected to different power sources or each pair can be connected to the same power source. The bus bars of the receptacle can have various configurations, including non-overlapping orientations.

Abstract: An apparatus and method are provided for operating one of a plurality of lamps employed within a luminaire via a single ballast, thereby extending the operational life of the luminaire. The operating lamp disables the lamps downstream from itself by preventing current from conducting through lamps other than the operating lamp. The lamps upstream from the operating lamp typically lack a sufficient voltage for ignition and operation. However, if any of the upstream lamps begin to operate, the lamps operating downstream cease to operate. In the event that two lamps begin to operate in an asymmetric manner, a capacitor is preferably provided to maintain a reverse voltage with respect to the output of the ballast, thus ensuring reduced voltage across the rectified lamps until one lamp extinguishes and the second lamp begins to operate.

Abstract: A self-adjusting end cap for capping an object having an opening. The end cap includes a base that has an inner and an outer surface, at least one post connected to the base inner surface, and at least one rib extending outwardly from the post. The rib is adapted to fit in a channel in an opening of an object to be capped. When the end cap and object are aligned for connection, the rib extends beyond an inner wall of the channel. A portion of the rib is sheared off by the inner wall of the channel upon insertion of the post and rib in the channel, thereby positioning the end cap within the object. The posts in combination with the ribs create a precise and tight friction fit between the end cap and the object. Preferably, the end cap has two posts, each with a rib extending outwardly therefrom, and the object has two channels, each having an inner wall. The outer edges of the ribs are separated by a first distance, and the channels are separated by a second distance.

Abstract: A lamp support includes a support surface and a main bracket member. The main bracket member includes first and second opposing ends that define a length of the main bracket member, and an elongated aperture extending between the first and second ends. A lamp holder is coupled to the main bracket member adjacent its second end and spaced from its first end. A fastener member is slidably received in the elongated aperture of the main bracket member and releasably couples the support surface and the main bracket member at a coupling axis. The main bracket member slides with respect to the fastener member and the coupling axis along the elongated aperture moving the lamp holder radially relative to the coupling axis, and rotates with respect to the fastener member about the coupling axis moving the lamp holder circumferentially relative to the coupling axis.

Abstract: A vernier ratchet-type lens adjuster for use with a lens array allows for fine adjustment of the coverage pattern of a sensor. The lens array can have notches, or teeth, that interact with a single tooth, or pawl, of a lens adjuster unit to maintain the position of the lens array. A user can make fine adjustments to the coverage pattern of the sensor by moving the lens array small increments. Alternatively, a rack and pinion type vernier adjuster can be used. One edge of the lens array has notches, forming the teeth of a rack portion. A pinion, or gear, has compatible teeth for mating with the rack portion. The pinion has a knob or screw accessible from a port in the sensor housing. When assembled, the rack, pinion and lens array are mated. A user can adjust the coverage pattern of the lens array by rotating the pinion, which in turn moves the rack, or the lens array, along a predetermined path.

A single continuous conductive member is attached to the sheet, the continuous conductive member having two unitary portions. The one portion is disposed in the central area of the sheet in a grid pattern, and the other portion is disposed in the outer perimeter of the sheet in a border pattern surrounding the one portion. The continuous conductive member has a connection end portion for electrical connection to the power source.

Abstract: A raceway fitting, including a first housing portion having a bottom surface, a first wall and a second wall, and a first coupling member adjacent said first wall. The first coupling member has a tapered surface with first and second ends, the tapered surface extending from an obtuse angle from the first wall. The adapter assembly further has a second housing portion with a first side portion and a second side portion. A second coupling member is located on the first side portion, the second coupling member having a first edge and a second edge. When coupling the first housing portion to the second housing portion, the first edge of the second coupling member engages the tapered surface of the first coupling member, adjacent the first edge and traverses the tapered surface in the direction of the second end, to facilitate the coupling thereof. This allows the two housing portions to be easily assembled and also allows the assembly to withstand an impact to the housing without the housing portions uncoupling.

Abstract: A method and apparatus for regulating a DC power supply, adaptable for use with a motion sensor switch, by limiting the leakage to ground current of the power supply to comply with U.L. Standards while also enabling the DC power supply to provide a stable DC output voltage which is essentially unaffected by changes in magnitude of the AC supply voltage or changes in ambient temperature. The method and apparatus employs first and second transistors, in which the base and collector of the first transistor and the base and collector of the second transistor are coupled to receive a voltage based on the AC supply voltage, and the emitter of both the first and second transistors are coupled to drive an output circuit of the DC power supply. The emitter of the second transistor is also coupled via a first resistor to the base of the first transistor, and the collector of the second transistor is also coupled via a second resistor to the base of the first transistor.
