  • Publication number: 20080129206
    Abstract: A system and method of automatically controlling exterior vehicle lights includes an image sensor and a controller to generate control signals. The control signals are derived based on information obtained from the image sensor as well as other detected parameters pertaining to the detected light source(s), the vehicle having the inventive control system, and the ambient environment. The control circuit may simply turn certain exterior lights on or off, or change the brightness, aim, focus, etc. to produce various beam patterns that maximize the illuminated area in front of the vehicle without causing excessive glare in the eyes of other drivers.

  • Patent number: 7253448
    Abstract: A semiconductor optical radiation package includes a leadframe, at least one semiconductor optical radiation emitter, and an encapsulant. The leadframe has a heat extraction member, which supports the semiconductor optical emitter and provides one or more thermal paths for removing heat generated within the emitter to the ambient environment, as well as at least two electrical leads for providing electrical coupling to the semiconductor optical radiation emitter. The encapsulant covers and protects the emitter and optional wire bonds from damage and allows radiation to be emitted from the emitter into the ambient environment. The semiconductor optical radiation package provides high emitted flux and is preferably compatible with automated processing techniques.

  • Patent number: 7199346
    Abstract: A control system is disclosed for automatically detecting moisture on the windshield of a vehicle. The automatic moisture detecting system includes an optical system for imaging a portion of the windshield onto an image array sensor, such as a CMOS active pixel sensor. The voltage of each of the pixels which represents the illumination level is converted to a corresponding gray scale value by an analog digital converter. The spatial frequency composition of the gray scale values are analyzed to determine the amount of rain present in order to provide a control signal to control the operation of the windshield wipers of the vehicle as a function of the amount of moisture present. The system is also adapted to detect the level of fog both on the interior of the windshield as well as the exterior of the windshield.

  • Patent number: 7142345
    Abstract: A mirror assembly includes a housing, an angularly adjustable power pack, wires for supplying power and mirror angle control, an electrochromic mirror subassembly including a heater, and a turn signal device. The components include individual connectors that plug into a multi-prong connector on the bundle of wires, or that piggyback into each other. Optionally, the heater incorporates an internal wire with end connectors for communicating power to opposite sides of the heater, and also includes layers of light-transmitting/diffusing material for diffusing light passing from the turn signal device through the diffusing material. A printed circuit board fits into a pocket in the panel-shaped carrier, and an integral retainer releasably secures the printed circuit board. The power pack is attached to the carrier via a ring of resilient fingers, and a continuous hoop flange prevents distortion of the carrier and in turn of the glass elements in the mirror subassembly.

  • Patent number: 7118931
    Abstract: The radiation emitter device of the present invention includes at least two radiation emitters emitting radiation of different wavelengths, first and second electrical leads electrically coupled to at least one of the radiation emitters, and an encapsulant configured to encapsulate the radiation emitters and a portion of the first and second electrical leads. The encapsulant is further configured to have a surface defining an optical lens including a plurality of concentric circular grooves. The optical lens is preferably a divergent lens. Preferably, the lens is a multi-faceted Fresnel lens structure having a plurality of risers and Fresnel facets defining the plurality of concentric circular grooves. The radiation emitter device may further include a secondary reflective cup, preferably a parabolic or elliptical reflective cup, disposed proximate the encapsulant about the periphery of the Fresnel lens structure.

  • Patent number: 7111968
    Abstract: A vehicle system is disclosed that includes a vehicle lamp assembly including a plurality of LEDs that emit white light so as to function as an illuminator light. The lamp assembly also may include a plurality of LEDs that emit colored light to function as a signal light. The lamp assembly may include a camera. The lamp assembly may serve as a CHMSL or as a tail light. The system also includes a controller that rapidly pulses the LEDs at a rate that is imperceivable by the human eye. The pulsing intervals of the LEDs may be related to the readout intervals of the camera sensor array. In this manner, the LEDs may be pulsed on during camera readout to increase the illumination while the camera is capturing an image, or may be pulsed off during camera readout to prevent feedback glare from interfering with image capture by the camera.
