  • Patent number: 10118555
    Abstract: This invention provides a lamp-equipped vehicle outer mirror in which a phenomenon is less likely to occur, the phenomenon being the one in which light emitted from a lamp appears in a light emission pattern that is different from that intended by a designer. A side turn signal lamp is incorporated in a minor housing. A downward inclined surface is formed at a position above a lens of the side turn signal lamp in the mirror housing. The downward inclined surface is inclined obliquely downward and is lustrous. A part of turn signal lamp light emitted from the lens to an external field is reflected by the downward inclined surface. A relative positional relationship between the lens and the downward inclined surface is set so that the reflected light passes through an area on an upper side relative to a horizontal direction.

    Abstract: A system apparatus, means and method for controlling a plurality of variable reflectance mirrors (or mirror segments), including a rearview mirror and side view mirrors, which change their reflectance level in response to a plurality of drive voltages applied thereto, for controlling the vehicle lighting system and for monitoring a vehicle interior for an automotive vehicle. The system includes a light sensing device and a control circuit formed as a single VLSI CMOS circuit. The light sensing device comprises a photosensor array having a field of view encompassing a vehicle interior. The logic and control circuit determines a background light signal from photosensor element signals generated by the photosensor elements in the photosensor array indicative of light levels incident on the photosensor elements. The circuit also determines a peak light signal in three different zones or sub-arrays of the photosensor array. The zones or sub-arrays may correspond to three mirrors or mirror segments.

  • Patent number: 6755542
    Abstract: An automatically dimming mirror includes a dimming element having variable reflectivity, the degree of reflectivity based on a control signal. An ambient light sensor is positioned to receive light from a region generally in front of the vehicle. The ambient light sensor outputs a discrete ambient light signal based on the amount of light incident on the ambient light sensor over an integration period. A glare sensor is positioned to view the scene generally behind the vehicle operator. The glare sensor outputs a discrete glare signal based on the amount of light incident on the glare sensor over an integration period. A dimming logic determines an ambient light level based on the ambient light signal. The glare integration period is determined based on the ambient light level. The glare signal resulting from the glare integration period determines a mirror glare level used to set the dimming element control signal.

  • Patent number: 6742904
    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.

    Abstract: An automatic optical lens sun shield comprises an elastic clip cartridge, a rotary connector and a tinted transparent optical lens screen. The elastic clip cartridge is constructed with spring clamp frames which can be pulled outward and clipped on original padded visor as well as detached from original padded visor without using any hand tool. The rotary connector is constructed with a positioning pivot shaft which drives the positioning pad to rotate. Thereby, the radiating teeth at the bottom of the positioning pad is engaged to the radiating positioning teeth of the rotating connector. Therefore, the rotary connector can rotate under the clip cartridge and is securely positioned thereon. The lower part of the rotary connector is formed with at least one pivot groove. The tinted transparent optical lens screen is engaged to the pivot groove via a rotary shaft.
