Abstract:
A densely populated micro miniature connector includes a plug and a receptacle configured to securely mate with each other. Connector plugs include an insert assembly having at least one double-ended pin, a housing, and a coupling ring. Connector receptacles include an insert assembly having at least one spring probe and a housing. The double-ended pin contacts the spring probe when the plug and the receptacle are connected.
Abstract:
A remote battery charger, comprising a DC-to-DC converter, able to accept a first DC current with a voltage of less than 13 VDC and able to produce, from said first DC current, a second DC current of at least a 15 amps at a voltage of at least 13.5 VDC, provided an adequate first DC current level. Also, the charger includes a current acceptance reduction input, whereby when said input is activated said DC-to-DC converter reduces its acceptance of said first DC current.
Abstract:
A combination luminaire and path of egress lighting includes a lamp housing and one or more auxiliary lamps. The lamp housing includes an electrical enclosure, a lamp mounting area and a lamp cover. A primary light source is positioned within and coupled to the lamp housing. The auxiliary lamps are coupled to and extend out from the exterior of the lamp housing. Each auxiliary lamp typically include a base plate, a stem member, and a task lamp housing. The base plate is coupled to the exterior of the lamp housing. The stem rotatably coupled on one end to the base plate and along the other end to the task lamp housing. By rotatably coupling auxiliary lamp along each end of the stem member, the task lamp housing has a large range of adjustability so that it can be aimed towards paths of egress after the luminaire is installed.
Abstract:
Apparatus, method, and system for rigidly supporting a switchgear bus assembly through the use of one or more support plates, thereby providing the primary support for the other active modules and bushings.
Abstract:
A fault interrupter and load break switch includes a trip assembly configured to automatically open a transformer circuit electrically coupled to stationary contacts of the switch upon the occurrence of a fault condition. The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.
Abstract:
A position indicator may include a position indicator display and mechanism. A polymer housing houses the position indicator display and mechanism and a one-piece clear polymer cover encloses the position indicator display and mechanism in the polymer housing. The position indicator may further include a hinge and hand-operated latch that secures the one-piece clear polymer cover to the polymer housing such that the one-piece clear polymer cover can be opened without the use of tools.
Abstract:
A connector system includes a plug and receptacle. The plug mates with the receptacle to connect two lengths of an Ethernet/power cable. Connector plugs and receptacles each include an insert assembly having a plurality of contacts for coupling to power conductors and network wires within the Ethernet/power cable. Contacts coupled to power conductors are shielded from contacts coupled to network wires.
Abstract:
A transient voltage suppression device includes a dielectric layer defining a receptacle for a variable impedance material proximate a gapped electrode. Methods for manufacturing the device and for formulating a variable voltage material at lower cost and with higher manufacturing yields is also provided.
Abstract:
A reflector for a light source, such as an LED, is provided with a shape which efficiently collects and directs energy to an illumined surface whereby almost 100% of the light is collected and distributed into a designer composite beam. The shape in one embodiment is comprised of three zones beginning with a parabolic surface of revolution at the base of the reflector, followed by a transition or straight conic zone and ending with an elliptical zone. In another embodiment the reflector shape is determined according to a transfer function which allows for arbitrary designer control of the reflected rays at each point on the reflector, which when combined with direct radiation from the source, results in a designer controlled composite beam or illumination. The device is more than 90% energy efficient and allows replacement of higher power, less energy efficient light sources with no loss in illumination intensity.
Abstract:
A lighting system comprises a row of light emitting diodes (“LEDs”) receiving electricity and producing light and heat. The row of LEDs can be located in a channel or a groove of a piece of material, such as an aluminum extrusion or a bent piece of metal. The channel can have an optically reflective lining, for example, providing either diffuse or specular reflection. Accordingly, the channel can reflect light emitted by the LEDs. The piece of material can also include a heat sink for transferring heat from the LEDs to air via convection or air flow. The heat sink can comprise fins or protrusions that facilitate convection.
