  • Publication number: 20180332990
    Abstract: A clothing hanger is disclosed with at least one integral convenient, refillable scented material compartment with a control mechanism to regulate the amount of scent emanating from the clothing hanger, including a pair of shoulders to support clothing connected to a hook extending upwardly from a hanger neck to opposing distal ends, so that the clothing hanger can be hooked over a closet rod or the like. At least one storage compartment is integral with the neck and shoulders of the clothing hanger for containing scented materials. A cartridge housing is integral with the storage compartment, and the cartridge housing is designed to receive a snap-in scented material cartridge. The user will determine which scent is desired, and then will fill the cartridge with the appropriate scent, snap the filled cartridge into the storage compartment and the cartridge housing, hang up the clothing on the hanger, and enjoy the scent when they remove the clothing from the hanger.

  • Patent number: 8391698
    Abstract: Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise exposing a plurality of pixels on an image capture device to a modulated light signal reflected from different regions of a scene adjacent a camera after different delays. The method may also comprise correlating intensity of the modulated light signal received by the image capture device for each the different delays to determine a flight time of the modulated light signal. The method may also comprise generating a Z-buffer corresponding to the different regions of the scene based on the correlation.

  • Patent number: 7983548
    Abstract: Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise actuating a light sensor after various delays to receive a plurality of modulated light signals reflected from different regions of a scene adjacent a camera. The method may also include determining distance information for the different regions of the scene based on brightness values for the plurality of modulated light signals reflected from the scene for the various delays. The method may also include storing the distance information in a Z-buffer at the camera.

  • Patent number: 7863997
    Abstract: A compact, high speed, miniaturized adaptive controller for a microwave power generator. A pair of directional couplers are arranged between a microwave source and a circulator to measure forward and reverse power. An electromagnet in the circulator may be controlled in response to a VSWR calculation. In some arrangements, the directional couplers may be loop-type directional couplers that are integrated into a waveguide magnetron launching assembly. The directional couplers may use a tapered coaxial line that presents an impedance that reduces along the length thereof. This enhances the directivity of the loop coupler and improves performance of the controller.

  • Patent number: 5563630
    Abstract: The present invention includes a remote mouse controller having a disc controller actuable by a user for the infrared remote signalling of all common mouse functional operations. Depression along the edge of the disc controller signals cursor movement and direction operations. Depression in the center of the disc controller signals selection of certain operational features such as the mouse "click", "double click" and "click-and-drag" operations. A plurality of user actuable fixed function and programmable function keys are also provided to facilitate user selection and input of keyboard type data.
