  • Publication number: 20120187657
    Abstract: A hitch device for converting a conventional wheelbarrow into a towable trailer. The wheelbarrow includes a tub, handles and at least one wheel. The hitch device includes an elongated tow bar, first and second engagement members, and a vehicle coupling assembly. Each of the engagement members has a handle capture, a cross bar, and a base. The handle capture is configured to slidably receive one of the wheelbarrow handles, and is connected to the cross bar. The base also projects from the cross bar. The first engagement member is separate from the tow bar, whereas the second engagement member is affixed to the tow bar. The handle captures are received over the wheelbarrow handles, respectively, and the bases fastened to one another to connect the first engagement member with the tow bar such that the hitch device is mounted to the wheelbarrow handles in a wedge-like fashion.

  • Patent number: 8118435
    Abstract: A display system for providing enhanced brightness projected images from a micro-projector. The system includes at least two micro-projector display devices, one or more sensors, and a controller. The sensors provide information to the controller indicative of the micro-projector display devices having been placed in proximity to each other to project identical images, the controller further being programmed to determine from information generated by the sensors their alignment and maximize cooperative pixel alignment between multiple images generated by the micro-projector display devices by offsetting a center of an image in one or more of the projector devices.

  • Publication number: 20120001545
    Abstract: An LED light bulb device including a bulb body, a cap and an LED assembly. The bulb body defines an exterior surface and an interior. The cap is mounted to the bulb body, combining to define a light bulb-like structure. The LED assembly includes a substrate, LEDs, transformer circuitry and connective circuitry. The LEDs and the connective circuitry are maintained by the substrate, with the connective circuitry electrically connecting the LEDs and the transformer circuitry. The transformer circuitry is adapted to modify incoming power for powering the LEDs. The LED assembly is mounted to the light bulb-like structure such that the LEDs are disposed along the exterior surface of the bulb body, with light from the LEDs being directed inwardly into the interior and then outwardly from the interior. The LED assembly can further include a heat sink body encompassing the LEDs.

  • Publication number: 20110103055
    Abstract: An LED light bulb device including a bulb body, a cap, an LED assembly, and first and second light affecting features. The cap is mounted to the bulb body for connection to an electrical socket. The LED assembly includes a plurality of LEDs and framework. The framework maintains the LEDs relative to the bulb body such that emitted light is directed at an LED region of the wall. The first light affecting feature is associated with the LED region of the wall, whereas the second light affecting feature is associated with a diffusion region of the wall, with the diffusion region being apart from the LED region. The first light affecting feature affects light in a manner different from that of the second light affecting feature. The light affecting features are selected to affect or alter light emitted from the LEDs to provide a desired Kelvin color temperature and diffusion.

  • Patent number: 7920902
    Abstract: A mobile personal audio device including a case maintaining a power source, first and second speakers, a microcontroller, and first and second stem assemblies. The stem assemblies extend from opposite sides of the case, respectively, and each include a tube having a first end adjacent and open to a corresponding one of the speakers and terminating at a second end. The stem assemblies are configured such that the tube is positionable in a user-selected extended state in which the second end of the tube is displaced from the case, and a collapsed state in which the second end is in close proximity to the case. In the extended state, the case is locatable at the back of the user's neck, with the tubes extending along opposite sides of the user's head. The microcontroller operates the speakers to generate audio sounds waves that are delivered to the user's ears.

  • Publication number: 20100180190
    Abstract: A portable user interface device for performing wireless communications. The device includes a case, a display screen, a speaker, a microphone, a sensor, and a computer. The computer is disposed behind the display screen to define a display side, and the sensor is located adjacent the display side. The computer is programmed to control operation of the display screen and to operate a wireless form-filling module, a wireless data transfer module, and an application module. The form-filling module is of a type adapted to promote source data-type interface with a client server servicing the user interface device and limited data transfer capacity. The data transfer module includes a wireless transceiver and is adapted to communicate with a data transfer service on a non-priority, limited size basis. The application module performs a designated operation via the form-filling module and the data transfer module, displaying indicia immediately adjacent the sensor.

  • Patent number: 7521007
    Abstract: Microstructured nuclear fuel adapted for nuclear power system use includes fissile material structures of micrometer-scale dimension dispersed in a matrix material. In one method of production, fissile material particles are processed in a chemical vapor deposition (CVD) fluidized-bed reactor including a gas inlet for providing controlled gas flow into a particle coating chamber, a lower bed hot zone region to contain powder, and an upper bed region to enable powder expansion. At least one pneumatic or electric vibrator is operationally coupled to the particle coating chamber for causing vibration of the particle coater to promote uniform powder coating within the particle coater during fuel processing. An exhaust associated with the particle coating chamber and can provide a port for placement and removal of particles and powder. During use of the fuel in a nuclear power reactor, fission products escape from the fissile material structures and come to rest in the matrix material.
