G01V 1/06

US Classification:

361247

Abstract:

Switch card apparatus are disclosed. In one embodiment, a circuit includes a first portion having a first switch adapted to be coupled to a first voltage, a second portion including a second switch, and a third portion including a third switch. The first portion activates the first switch to couple the first voltage to the second portion. Similarly, the second portion activates the second switch in response to a second input signal and the first voltage to couple a second voltage to the third portion. Finally, the third portion activates the third switch in response to a third input signal and in response to the second voltage from the second portion to couple a control voltage to a load. Embodiments of the invention provide the desired reliability suitable for a variety of electrical systems, including arming and firing applications over a wide voltage and wide current range.

Abstract:

A hanger bar for supporting a recessed light fixture is attachable to ceiling joists or a T-bar grid of a drop down ceiling. First and second bars of the hanger bar slide and telescope. First and second spring clips are detachably coupled to the brackets at the ends of the first and second bars, respectively. Each of the first and second clips has a pair of downwardly extending arms bent inwardly toward one another, a first leg extending from a first arm, a second leg extending from a second arm, and an outwardly-extending foot on the second leg. The spring clips snap on to the T-bar grid. Each bracket includes a nail that is angled away from the hanger bar and downward so that the nail head is below the level of the hanger bar. The angled nails enable easy hammer strikes to attach the hanger bar to ceiling joists without accidental hammer blows to the hanger bar.

Abstract:

A recessed ceiling light fixture with spring biased retainer clips that retract flush or are biased away from the side of the can housing for installation is disclosed. The fixture includes a housing having a side wall, a top wall, and an open bottom. Two rigid retainer clips are mounted diametrically opposed on the housing. Each retainer clip has a mounting tab inside the housing extending into a leg that passes out of the housing, which leg is bent to form an elbow, which elbow extends to a strut passing back into the housing, wherein the mounting tab selectively engages the side wall to limit movement of the spring clip. A bolt and coiled spring create compliance and bias in the spring clip by passing loosely through a slotted opening in the top wall at one end and joining the mounting tab at the other end.

International Classification:

F21V 29/00

US Classification:

362294, 362257, 362 92

Abstract:

A recessed lighting fixture providing illumination from a light source including a plurality of light emitting diodes (LEDs) wherein the fixture is placed within the ceiling space above a ceiling panel or wall. The fixture has a low aspect ratio heat sink. An interchangeable trim ring has an integrated light reflector and attaches to the bottom of the heat sink via rare earth or super magnets. A flange of the heat sink and a flat annular surface of the trim ring engage each other, providing a large contact surface to enable conductive heat transfer. The flange and flat annular surface are located below the ceiling panel, which is at room temperature to help cool the recessed LED lighting fixture through radiation and air convection.

Abstract:

In a nuclear process control system, a priority logic module (PLM) is provided. The priority logic module comprises a plurality of input ports, each input port associated with one of a plurality of priorities, a plurality of output ports, and a test mode select port associated with a test mode select signal. The test mode select signal selects one of a normal mode or test mode, each mode being associated with matching signals received by the input ports to signals sent by the output ports. The priority logic module further comprises a configurable priority logic circuit, wherein the priority logic circuit maps one of the input ports to one of the output ports.
