  • Patent number: 10540896
    Abstract: An acquisition unit acquires a light path length rij corresponding to an emission direction of emitted light, which is surrounding information of a moving body obtained by using a laser radar mounted on the moving body, a traffic mirror information including a center position N of a traffic mirror on a map, and position information of the moving body on the map. Then, on the basis of the acquired traffic mirror information and the acquired position information of the moving body on the map, an extraction unit extracts a light path length acquired via the traffic mirror from the acquired light path length rij, and then calculates an object reflection position corresponding to the extracted light path length. This makes it possible to obtain surrounding information in a blind spot for a driver while increasing robustness with respect to the surrounding information, and thus advanced driving assistance can be implemented.

    Abstract: A solar central receiver system employing common positioning mechanism for heliostats relates to a system of concentrating and harvesting solar energy. The heliostats of said system are positioned like facets of a Fresnel type of reflector. The heliostats are placed in arrays, wherein each array has a common positioning mechanism. The common positioning mechanism synchronously maneuvers the arrays of heliostats in altitudinal and/or azimuthal axis for tracking an apparent movement of the sun. The common positioning mechanism is employed for synchronously orienting said heliostats with respect to a stationary object and the sun such that incident solar radiation upon said heliostats is focused upon said stationary object from dawn to dusk. Subsequent to each said orientation of said heliostats, collective disposition of said heliostats always forms an arrangement that is capable of reflecting and thereby focusing incident solar radiation upon said stationary object.

  • Patent number: 9509250
    Abstract: A solar cell or module is illuminated at one sun intensity and is placed into short circuit. Current and voltage measurements are taken. Control circuitry commands a second, higher terminal voltage of the solar cell such as a maximum power voltage. A higher intensity light pulse (for example, three suns) is applied to the solar cell or module when the second voltage is commanded. Voltage ramps more quickly because of the high-intensity light pulse. When the second terminal voltage is reached the light pulse terminates and measurements are taken while the solar cell remains illuminated at one sun intensity. The solar cell is placed into open circuit conditions and in conjunction with that action another high-intensity light pulse is applied. When the steady-state open circuit voltage for one sun is reached the pulse terminates. Characteristics are measured including current and voltage at the terminals of the solar cell or module.

  • Patent number: 9401439
    Abstract: Apparatuses and methods include a solar array having one or more string buses of series-connected solar modules. The current outputs from the solar modules on each string bus can be balanced along with the voltage output from the string buses. Local management units coupled between the solar modules and the string buses are configured to control the voltage output from each solar module. When the solar modules on each string are balanced, and when the string buses are balanced (or before the solar modules and string buses are balanced), an inverter or other device connected to the solar array can find the array's maximum power point via a maximum power point tracking algorithm.

  • Patent number: 9274202
    Abstract: Time-of-flight technology may be combined with optical detection technology identifying an angle of a light pulse emitted from a transmitter and reflected off an object based on a proportion of the reflected light pulse detected at each of at least two light sensors. The optical detection technology may include a light detector with two or more light sensors arranged at different orientations with respect to an aperture in the detector so that each sensor is able to detect a different subset of the light passing through the aperture. The effective angle of the light passing through aperture may then be calculated from the proportion of light detected at the each of the sensors. The effective angle information may be combined with a calculated time-of-flight of the light pulse to accurately identify a position of the object relative to the detector in two or three dimensions.

  • Patent number: 9256007
    Abstract: An apparatus for distributing light from a waveguide through a collimating array, or collecting light over a given area into a waveguide. Light received within a waveguide is propagated transmissively and retained by total internal reflection, except in response to impinging upon deflector elements which sufficiently redirect the light to escape the waveguide into a collimator array that aligns and distributes the light. In a light collector, a collection array collects and collimates the received light and directs it at the surface of a waveguide, within which deflectors properly positioned in relation to each collector of the collector array, deflect the angle of the light so that it propagates through the waveguide in response to total internal reflection. The apparatus can be fabricated into an efficient and compact form.

    Abstract: An automatically adjusting light shelf has a circuit of components used to measure light levels within a space; a light shelf hinged to a window assembly, used to reflect light entering the space; and a rotation device used to alter the light entering the space by rotating the light shelf. The light levels are measured using light sensors having a capacitive component and phototransistor in parallel with one another, a microcontroller, and optionally, a clock. The automatic operation of the light shelf can be overridden for manual operation. A method of using the automatically adjusting light shelf includes the steps of measuring a differential between the light levels reaching the light sensors; determining a direction to rotate the light shelf to alter the light; and rotating the light shelf so that the reflected light is optimized within the space.
