Patent number: 6967318Abstract: A light-responsive control device of an electrochromic rearview mirror system is disclosed. The light-responsive control device includes a downward ambient light sensor and a, discriminating circuit for generating a first and a second reference levels provided for daytime and nighttime glaring determination, respectively. By providing a photo-sensor for each rearview mirror, and individually comparing the outputs of the photo-sensors with the first or the second reference level, the color-change degrees of different rearview mirrors can be individually controlled. By providing a variable resistor for the drive circuit, the initial reflection rate of the rearview mirror can be adjusted optionally.Type: GrantFiled: February 13, 2003Date of Patent: November 22, 2005Assignee: Exon Science, Inc.Inventors: Wen-Wei Su, Kuei-Hung Chen, Shun-Hsiang Hsiao

Patent number: 6953253Abstract: A vehicle photosensing system includes a photosensor array that is disposed within the interior cabin of the vehicle and having a field of view forward through the windshield of the vehicle. The photosensing system further providing a control for either controlling operation of a vehicle headlight or monitoring a surface condition of the windshield of the vehicle. If controlling the vehicle headlight, preferably the control transitions the headlight from a first beam mode to a second beam mode in response to detection of a headlight and/or a taillight by the photosensor array within its forward field of view. If monitoring a surface condition of the windshield of the vehicle, the photosensing system operates the vehicle's windshield wiper system in response to a signal generated by the control.Type: GrantFiled: September 14, 2004Date of Patent: October 11, 2005Assignee: Donnelly CorporationInventors: Kenneth Schofield, Mark Larson

Patent number: 6918674Abstract: A vehicle rearview mirror system includes an electro-optic reflective element, an ambient light sensor that is operable to sense ambient light, a glare light sensor that is operable to sense glare light and a circuit that is responsive to the ambient glare light sensors which establishes a reflectance level of the reflective element. The circuit includes a sensor-responsive device and a controller. The sensor-responsive device produces an output that is a function of light sensed by glare and ambient light sensors. The controller connects one of the glare and ambient light sensors at a time with the sensor-responsive device to establish glare and ambient light levels and thereby the reflectance level of the reflective element. The mirror system may include a display operable to project light through the reflective element and may control the intensity of the display as a function of the glare light and ambient light.Type: GrantFiled: April 30, 2003Date of Patent: July 19, 2005Assignee: Donnelly CorporationInventors: John P. Drummond, Kenneth Schofield

Patent number: 6904348Abstract: A vehicular control system comprises a rearview mirror assembly and a microcontroller. The rearview mirror assembly comprises a housing and a variable reflectivity electro-optic mirror element. The microcontroller is operable to control the reflectivity of the variable reflectivity electro-optic mirror element. The microcontroller may be operable to control a plurality of accessories of the vehicle via a node of a vehicle control network. The microcontroller may be operable to receive signals from and/or transmit signals to at least one of the accessories via the node of the vehicle control network. The microcontroller may be in communication with a second microcontroller located in the mirror housing or exterior to the mirror housing. The microcontroller and the second microcontroller may be cooperatively operable. The microcontroller and the second microcontroller may be in master/slave relationship.Type: GrantFiled: February 3, 2003Date of Patent: June 7, 2005Assignee: Donnelly CorporationInventors: John P.

Patent number: 6902284Abstract: An interior rearview mirror system suitable for use in the interior cabin of a vehicle is provided that includes an interior rearview mirror assembly having an interior rearview mirror support adapted for attaching to a windshield or header portion of the vehicle. The interior rearview mirror assembly includes an interior rearview mirror casing and an interior rearview mirror reflective element. The interior rearview mirror casing is pivotally adjustable about the interior rearview mirror support whereby adjustment of said mirror casing by a driver of the vehicle adjusts the rearward field of view of the interior rearview mirror reflective element in order for the driver to see rearwardly when driving.Type: GrantFiled: December 2, 2002Date of Patent: June 7, 2005Assignee: Donnelly CorporationInventors: Barry W. Hutzel, Niall R. Lynam, Darryl P. DeWind, John O. Lindahl
