Patent number: 8319766Abstract: Electronic Paper Displays can suffer from “ghosting” or previous images remaining partially visible after the display has updated to show a new image. A pseudo-random noise intermediate image is used to make the ghosting less visible to human observers. Further, other intermediate images can be used to convey visible information or to convey secret information, e.g. a watermark. A control signal for driving the bi-stable display from the current optical state to an intermediate state, then to a final optical state is also determined. In some embodiments, the intermediate state for each pixel is determined in a pseudo-random manner. The pseudo-random noise values are applied to the bi-stable display to remove noise and other artifacts from the end resulting images. The determined control signal is applied to the bi-stable display to drive the bi-stable to the intermediate state, then to the final optical state.Type: GrantFiled: March 31, 2008Date of Patent: November 27, 2012Assignee: Ricoh Co., Ltd.Inventors: Michael J.

Publication number: 20120224248Abstract: An electrochromic interior reflective element for an interior rearview mirror assembly of a vehicle includes front and rear substrates and an electrochromic medium sandwiched between the front and rear substrates. The electrochromic medium is disposed in an interpane cavity established between a third surface of the rear substrate and a second surface of said the substrate, and the electrochromic medium is bounded by a perimeter seal. A conductive layer is disposed at a fourth surface of the rear substrate. A non-conductive layer covers a covered portion of the conductive layer and leaves an exposed portion of the conductive layer exposed. An electronic circuitry component is disposed at the fourth surface of the rear substrate. The electronic circuitry component is electrically connected to the exposed portion of the conductive layer.Type: ApplicationFiled: May 14, 2012Publication date: September 6, 2012Applicant: DONNELLY CORPORATIONInventors: Kenneth Schofield, David C. Wight, Mark E. Kramer

Patent number: 8256940Abstract: A cover for use in connection with a vehicle light having a light source and a light reflector is provided. A lens of the cover has an electrically activatable material switchable between a light inhibiting state and a light transmissive state. The electrically activatable material prevents the transmission of visible light from entering into and reflecting out from the vehicle light when the electrically activatable material is set to the light inhibiting state. The lens has an area without having the electrically activatable material such that visible light from the light source is also to pass through the area. A baffle having the electrically activatable material extends from the body of the lens. The baffle blocks a portion of the visible light that passes through the area of the lens from traveling in certain directions when the electrically activatable material is in the light inhibiting state.Type: GrantFiled: September 16, 2009Date of Patent: September 4, 2012Assignee: Control Solutions LLCInventors: Alyn Brown, James Wiff

Patent number: 8258433Abstract: A vehicular interior rearview mirror assembly includes an electro-optic reflective element, a photo sensor and a light concentrator. The electro-optic reflective element has a front substrate with a first surface and a transparent second surface electrically conductive coating disposed on a second surface, and the electro-optic reflective element has a rear substrate with a third surface transflective metallic reflector disposed at a third surface thereof. The photo sensor is disposed behind a fourth surface of the rear substrate and operable to detect light passing through the transflective metallic reflector and the electro-optic reflective medium disposed between the second and third surfaces. The light concentrator is disposed between the photo sensor and the fourth surface of the rear substrate, and the light concentrator receives light passing through the transflective metallic reflector of the electro-optic reflective element and concentrates light onto a light sensing surface of the photo sensor.Type: GrantFiled: March 21, 2011Date of Patent: September 4, 2012Assignee: Donnelly CorporationInventors: Donald C.

Publication number: 20120218620Abstract: This invention contemplates integrating laser scribing/patterning the component layers of electrochromic devices by directly removing (ablating) the material of the component layers. To minimize redeposition of laser ablated material and particulate formation on device surfaces a number of approaches may be used: (1) ablated material generated by the focused laser patterning may be removed by vacuum suction and/or application of an inert gas jet in the vicinity of the laser ablation of device material; (2) spatial separation of the edges of layers and patterning of lower layers prior to deposition of upper layers; and (3) the laser patterning step may be performed by a laser beam focused directly on the deposited layers from above, by a laser beam directed through the transparent substrate, or by a combination of both.Type: ApplicationFiled: May 1, 2012Publication date: August 30, 2012Applicant: Applied Materials, Inc.Inventors: Byung Sung Kwak, Nety Krishna
