  • LED LUMINAIRE
    Publication number: 20120230034
    Abstract: A luminaire includes an electrical base, an optic, and a heat sink disposed between the base and the optic. The lens has a first curved portion, a second curved portion and a third portion. An LED light source is coupled to the heat sink with LED modules arranged to direct light in the same direction. A frustoconical member having a reflective outer surface is disposed between the lens and the LED light source wherein the LED light source has LED modules disposed to emit at least a portion of light toward the reflective outer surface such that light is emitted with a substantially even luminous intensity in a 0°-135° zone.

  • Reduced-voltage, linear motor systems and methods thereof
    Patent number: 8217553
    Abstract: A linear motor system includes an element with a threaded passage, a threaded shaft, and a driving system. The threaded shaft has an axis of rotation which extends through and is at least partially engaged with at least a portion of the threaded passage. The driving system comprises at least two members operatively connected to the element. Each of the two members comprises two or more piezoelectric layers and electrodes which are coupled to opposing surfaces of each of the piezoelectric layers. The members are configured to expand and contract in a direction along the axis of rotation. The driving system is configured to subject the element to vibrations causing the threaded shaft to simultaneously rotate and translate in the direction along the axis of rotation through the element and apply an axial force in the direction along the axis of rotation.

  • METHODS FOR CONTROLLING ONE OR MORE POSITIONING ACTUATORS AND DEVICES THEREOF
    Publication number: 20120019185
    Abstract: A method, computer readable medium, and apparatus for controlling a moveable element includes generating and providing with a control device one or more driving signals to one or more positioning actuators to move the moveable element towards a target position based on a target travel distance and a calibration value. The control device determines when a post-movement position of the moveable element is outside of a tolerance range of the target position. The control device recalibrates the calibration value when the post-movement position is determined to be outside of the tolerance range. The control device repeats the generating, the determining, and the recalibrating as open loop steps until the post-movement position is within the tolerance range or until a limit, if any, on attempts is reached.

  • Concrete finishing machine
    Patent number: 8083510
    Abstract: A machine for imprinting patterns onto uncured concrete in an elongated bed includes a frame for positioning the finishing machine over the bed. A lower patterning unit suspended from the frame is movable backward and forward of the concrete bed and a press assembly moves the pattern in and out of contact with uncured concrete on the elongated bed.

  • Systems and methods for conducting simultaneous vibration and electrical testing
    Patent number: 8079267
    Abstract: A mounting pedestal is designed to hold a DUT in position for both electrical testing and vibration testing. The design is such that the pedestal can remain thermally sealed from an environment created within a confined area so as to impart vibration to a DUT positioned within the environmentally protected area, the vibration coming from a vibrator outside the environmentally sealed area. The pedestal, in one embodiment, extends through the base of a DUT holding tray while still preserving the environment within the sealed area. In one embodiment, the pedestal can position the DUT in any of several selected orientations.

  • Linear drive systems and methods thereof
    Patent number: 8059346
    Abstract: A drive system and methods thereof include at least one actuator assembly that detachably engages a moveable system and at least one control system. The control system voltage biases the actuator assembly in at least one direction at a rate which causes the at least one actuator assembly to slip with respect to the detachably engaged moveable system. The control system also voltage biases the actuator assembly in at least one other direction at a rate which causes the at least one actuator assembly to stick and move with respect to the detachably engaged moveable system.

    Abstract: A network operation center for a light management system having networked intelligent luminaire managers. A plurality of networked luminaire managers, each collocated with a respective luminaire, monitor the status of their respective luminaires. The luminaire managers include transmitters for transmitting status information about their respective luminaires and third-party devices to a network server. The network server forwards the received status information from the networked luminaire managers to a computer of an owner/operator of the plurality of luminaires and/or a third-party user. The luminaire managers communicate with each other, whereby they form a network.
