Patent number: 8816999Abstract: Drive voltages of a liquid crystal display are adjusted based on one or more environmental conditions. The pixel drive voltages may be adjusted based on temperature. A pixel voltage may be varied such that it is a higher voltage at relatively lower temperatures and a lower voltage at relatively higher temperatures. The window voltage may be varied based on temperature. The window voltage may be stepped through different values within a display phase. The window voltage may be varied during a blanking period of the display phase such that the pixel sees a relatively larger voltage to obtain a desired initial state more quickly. Then, during a light modulating time period, the window voltage may be stepped such that there is a lower voltage field for holding the state of the pixel.Type: GrantFiled: May 27, 2011Date of Patent: August 26, 2014Assignee: Citizen Finetech Miyota Co., Ltd.Inventors: James M. Dallas, David B. Hollenbeck, Per Harold Larsen, Rainer M. Malzbender, Earle R. Vickery, III, Michael Wayne Yee

Patent number: 8487853Abstract: Methods and devices for generating grayscale using digital pulse width modulation between optical states. Grayscale may be generated for each component color using multiple algorithm cycles per display field. Subsets of binary weighted bit values for data values of each component color may be split across algorithm cycles to reduce the number of data comparisons per color per display field. The total number of data comparisons per color per display field may be reduced by half or more.Type: GrantFiled: April 28, 2011Date of Patent: July 16, 2013Assignee: Citizen Finetech Miyota Co., Ltd.Inventors: James M.

Publication number: 20110169882Abstract: A display device adjusts the operational timing of the illumination source relative to pixels of the display device. Grayscale may be generated in the pixels using pulse width modulation. The operational timing may be adjusted based on the temperature of the display device. The display device may be a liquid crystal display device and the operational timing of the illumination source may be adjusted to compensate for variation in the response time of the liquid crystal material based on temperature.Type: ApplicationFiled: March 18, 2011Publication date: July 14, 2011Applicant: MICRON TECHNOLOGY, INC.Inventors: JAMES M.

Publication number: 20100245212Abstract: A microdisplay having interface circuitry on the same silicon backplane to allow it to receive digital images and video in a variety of formats and convert same to field sequential color signals for generation of full color images. It includes column data processors having a comparator for each block of N-columns of pixels. Image data is double-buffered in SRAM memory cells located beneath the pixel electrodes, but not within each pixel. The stored data is logically associated with each pixel via the column data processors. Image compression is accomplished by converting RGB data to a variant of YUV data and sampling the color components of the converted data less frequently than the luminance components. The SRAM image buffer consumes a reduced amount of power. A temperature compensation scheme allows the temperature of the microdisplay to be sensed and the drive voltage to the pixel electrodes to be varied in response thereto.Type: ApplicationFiled: June 14, 2010Publication date: September 30, 2010Inventors: JAMES M.

Patent number: 5180283Abstract: A manually operated pump includes a pulley sheave oppositely wound with cord and rotatably mounted on a support element, a two-stage pump, and a reciprocal action shaft. The shaft is mounted eccentrically through the assembled pump, including through a clearance hole and slot in a main piston of the pump. The pump is a cylinder with a double-ended piston slidably mounted within and forming a main chamber at each end of the cylinder. An offset high pressure piston extends into the main chamber from each cylinder end for operation with offset high pressure chambers defined in each end of the double-ended piston. Passageways with differential air pressure valves lead from the slot to the main chambers, from the main chambers to the high pressure chambers, and from the high pressure piston to outlets.Type: GrantFiled: July 5, 1991Date of Patent: January 19, 1993Inventor: Earle R.

Patent number: 3933002Abstract: A skating rink comprising a rigid wall forming the periphery of a closed area, and a sheet, spread over the area and the wall, to form a water container. The wall is formed of elongated flexible tube of plastic sheet which is placed in a peripheral configuration and then filled with space-filling, rigid material, either water, which is allowed to freeze, or formed-in-place plastic foam. The sheet is held in place either by tucking its edges under the wall or by wire clips which hold the sheet and wall together. A plastic foam blanket can be used to reduce puncturing of the wall.Type: GrantFiled: June 17, 1974Date of Patent: January 20, 1976Inventor: Earle R. Vickery
