  • Publication number: 20150300622
    Abstract: A flushmount luminaire is configured to be flush mounted on a mounting surface. The flushmount luminaire includes a light source having a plurality of light emitting diodes (LEDs); a combination heat spreader and heat sink disposed in thermal communication with the light source such that the combination heat spreader and heat sink facilitates transfer of heat away from the LEDs; and, a power conditioner structurally configured and disposed to receive AC voltage from an electrical supply and to provide DC voltage to the plurality of LEDs. The combination heat spreader and heat sink has an outer dimension that is larger than: an opening defined by a nominally sized can light fixture; and, an opening defined by a nominally sized electrical junction box. A back surface of the combination heat spreader and heat sink is configured to permit the flushmount luminaire to be flush mounted on the mounting surface.

  • Publication number: 20150219892
    Abstract: A compact wide-angle optical beam steering device includes a first rotor with a first mirror surface and a second rotor with a second mirror surface. The rotors are arranged to rotate about an axis in response to frictionally coupled vibration motors. Drive circuits are coupled to the vibration motors and a control device is coupled to the drive circuits. The control device is configured to execute programmed instructions comprising generating and providing one or more driving signals to the vibration motors to drive the rotors to an angular position about the axes. A light source is positioned to emit a beam directed to the first mirror surface. The beam is reflected from the first mirror and contacts the second mirror. The second mirror is positioned to reflect the beam to exit the steering device at a pointing direction determined by the angular position of the mirrors.

  • Publication number: 20150198005
    Abstract: A well packer includes an expandable member carried on a mandrel, the mandrel including a groove formed on at least a portion of an outer radial surface of the mandrel; a back-up assembly carried on the mandrel adjacent the expandable member; and a fold back assembly carried on the mandrel adjacent the back-up assembly, the fold back assembly including a snap ring carried on the mandrel and adapted to move into the groove and adjust the expandable member into an expanded position in substantially sealing contact with a tubular.

  • Publication number: 20150092421
    Abstract: A luminaire includes a light source having a plurality of light emitting diodes (LEDs), a heat spreader, and a substantially ring-shaped trim plate. The heat spreader is disposed between and in thermal communication with the light source and the trim plate such that the heat spreader facilitates transfer of heat from the LEDs to the trim plate. The trim plate is structurally configured and disposed for dissipating heat generated by the light source. The trim plate has an outer dimension that is larger than: an opening defined by a nominally sized can light fixture; and, an opening defined by a nominally sized electrical junction box.

  • Patent number: 8967844
    Abstract: A luminaire includes a heat spreader, a heat sink, a light source and an outer optic. The heat sink is substantially ring-shaped and is disposed around and in thermal communication with an outer periphery of the heat spreader. The light source is disposed in thermal communication with the heat spreader, the light source having a plurality of light emitting diodes (LEDs) that are disposed in thermal communication with the heat spreader. The outer optic is disposed in optical communication with the plurality of LEDs. The heat spreader, the heat sink and the outer optic, in combination, have an overall height H and an overall outside dimension D such that the ratio of H/D is so dimensioned as to: cover an opening defined by a nominally sized four-inch can light fixture; and, cover an opening defined by a nominally sized four-inch electrical junction box.

  • Patent number: 8933703
    Abstract: A module is used for interfacing between a particular device to be tested (DUT) and a test station having a universal set of connections. The module is adapted for bridging both the physical and electrical differences between connection points available on the DUT and the universal test connections. The module contains information (personality data) unique to the particular DUT and is designed to mount in a tray in which the DUT is positioned. The personality module resides partially within an environmentally controlled area and an area outside of the environmentally controlled area and is adapted to seal the environmentally controlled area so as to maintain testing integrity therein. In one embodiment, the connections between the module and the test station occur outside of the environmentally controlled area.

  • Patent number: 8797152
    Abstract: A haptic actuator apparatus and a method of making the same include an ultrasonically vibrating motor and its housing. The housing includes a guide structure coupled to the ultrasonically vibrating motor and at least one spring. The guide structure defines at least one path of motion of the ultrasonically vibrating motor. The at least one spring delimits the at least one path and generates human-detectable vibrations in response to an impact with the ultrasonically vibrating motor.

  • Patent number: 8777512
    Abstract: A vertically stackable and retrofittable traffic cone linking system having a plurality of linking cuffs substantially conically shaped linking cuffs having four connection points, sized and configured to be removably secured to a standard traffic cone and a traffic cone linking connector removably connected to the linking cuffs. Once the traffic cone linking cuff is linked to the traffic cone linking connector, the traffic cone linking system can be can be arranged in a predetermined configuration or arrangement to alert onlookers of a particular hazard or to impede access to a given location.

  • Patent number: 8757275
    Abstract: An apparatus for isolating a first zone from a second zone in a subterranean wellbore. The apparatus includes an outer tubular and an inner tubular disposed within the outer tubular forming an annular flow path therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path that is in fluid communication with the second zone. A sleeve having at least one seal is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path.
