  • Patent number: 7988308
    Abstract: A control system for one or more electrochromic elements used in an outside electrochromic (OEC) mirror used in automobiles or other vehicular applications, to control the glare of both IEC elements used as a rearview mirror (20) as well as the OEC elements (24, 26) used as sideview mirrors (24, 26). An ambient light sensor (129) and glare sensor (133) operate to determine a glare level used to control both IEC and OEC electrochromic elements. The drive circuits for the OEC's elements may be controlled so as to account for various factors such as tinted glass characteristics in the vehicle.

  • Patent number: 7361875
    Abstract: Equipment on automotive vehicle is controlled by a system including at least one semiconductor light sensor having variable sensitivity to light. Each light sensor generates a light signal indicative of the intensity of light incident on the light sensor. Control logic varies the sensitivity of the light sensor and generates equipment control signals based on received light signals. Sensitivity of light sensors may be varied by changing the integration time for producing charge from light incident on light transducers, by selecting between light transducers of different sensitivity within the light sensor, by using a light transducer with a sensitivity that is a function of the amount of incident light, and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors, headlamps, and moisture removal means.

  • Patent number: 6861942
    Abstract: A vehicle antenna system incorporated into at least one side-view mirror of a vehicle includes a forward directed antenna and a rearward directed antenna to transmit and receive signals over corresponding forward and rearward-directed detection fields, respectively. The antennas act as directional transmitters and/or receivers, and a processing circuit discriminates between signals from different antennas without requiring any of the antennas to transmit identification signals to the processing circuit. Signal discrimination is conducted in part by sequentially selecting each antenna to obtain a corresponding antenna signal and, if required for a particular application, comparing the obtained signal with previously obtained antenna signals. The vehicle antenna system can be used, for example, in conjunction with tire pressure sensors to detect low tire pressure in a particular tire.

    Abstract: A light emitting assembly having a first light source and a second light source. The first and second light sources are oriented such that when the first and second light sources emit light, light emitted from the first and second light sources overlaps and is capable of forming effective white light. The light emitted from the first light source exhibits color coordinates different from the light emitted from the second light source. One of the light sources may be a photoluminescent source, such as a fluorescent dye or phosphor.

  • Patent number: 6789907
    Abstract: A control system for a plurality of electrochromic elements, for example, used in automobiles, to control the glare of the IEC elements used as a rearview mirror (20) as well as the OEC elements (24, 26) used as sideview mirrors (24, 26). The IEC element and each of the OEC elements is provided with an individual drive circuit (21, 22). The drive circuits for the OEC's elements may be customized to account for various factors such as the type of curvature as well as the size and shape. Since individual drive circuitry is provided for the IEC elements and each of the OEC elements, the reflectance of each of the electrochromic elements (20, 24, 26) can be relatively accurately controlled by way of glare signal from inside the automobile.

  • Patent number: 6696935
    Abstract: A tire monitoring (TM) system includes a peak detector signal filter that is configured to substantially prevent impulse noise from increasing a data slicer threshold, while simultaneously allowing the data slicer threshold to follow the variations in a received message attributable to signal fading. The TM system also automatically determines the location of a plurality of vehicle tires relative to the vehicle, utilizes a single receiver to receive messages of multiple lengths and masks an alarm when a missing ID code corresponds to a stored ID code associated with a flat tire.
