  • Patent number: 10054943
    Abstract: A UAV has two rotors. First and second sensors sense a first and second type of input respectively. The second type of input is different than the first type, the first sensor providing a first sensor output and the second sensor providing a second sensor output. The first sensor output is input to a first computer and the second sensor output is input to a second computer. The first and second computer communicate in parallel to process the first and second sensor outputs to create a control signal having a predetermined number of variables therein, each variable having an exclusive position within the signal. The first computer outputs a first variable and the second computer outputs a second variable, each output being assigned an exclusive position within the control signal. At least one of the first and second computers outputting the control signal to the rotors.

  • Publication number: 20170147007
    Abstract: An unmanned aerial vehicle has a substrate. A tether sensor is mounted on the substrate. The tether sensor determines an orientation of the tether relative to the substrate. A micro controller, receiving the measured orientation from the tether sensor, determines an orientation of the tether relative to the substrate, and as a function of the orientation, determines a corrective value and outputs the corrective value to the unmanned aerial vehicle as at least one of a roll output and a pitch output control signal.

  • Patent number: 7520634
    Abstract: Methods and apparatus in which at least one first LED generates first radiation having a first spectrum, and at least one second LED generates second radiation having a second spectrum different than the first spectrum. One or more controllers control at least one of the first radiation and the second radiation so as to control at least a color temperature of visible radiation. In one example, one or more sensors monitor at least one characteristic of sample radiation and provide one or more sensor signals to the one or more controllers, which in turn control at least the color temperature of the visible radiation based at least in part on the at least one sensor signal. In various implementations, the sample radiation may be ambient illumination (e.g., natural-light and/or light from other light sources), may be the visible radiation itself (e.g., to provide feedback to the one or more controllers), or generally any desired lighting condition to simulate.

  • Patent number: 7088040
    Abstract: Upconversion methods and devices that converts near-infrared light to the visible spectrum using a rare-earth-doped crystalline host for use as general and decorative lighting. The pseudo-monochromatic output of the processes can be specified by altering the amount and type of rare-earth material used and by selection of an appropriate host. Using rare-earth materials such as ytterbium-erbium or ytterbium-thulium can produce red, green and blue emissions, where the additive mixture of these colors yields a high-quality white light. The materials can be adjusted to achieve white light with any color temperature and high color-rendering index (CRI) for any general and decorative lighting applications both indoors and outdoors.
