  • Patent number: 11935480
    Abstract: Systems and methods are used to dim an emissive display such as an organic light emitting diode (OLED) display. A dimming level setpoint signal is received. At least one dimming process is selected from four dimming processes based on a magnitude of the dimming level setpoint signal. A first dimming process selects a subrange of pixel illumination levels from a range of pixel illumination levels. A second dimming process adjusts a VCOM voltage for the pixel array. A third dimming process selects between rolling shutter and global shutter. A fourth dimming process selectively utilizes one or more subpixels from an emissive display pixel based on the magnitude of the dimming level setpoint signal. The selected dimming process or processes are applied to the emissive display, there by dimming the display. The display can be an OLED display.

  • Patent number: 11623769
    Abstract: A self-healing shield panel for protecting a spacecraft against High Velocity Particles (HVPs). The self-healing shield includes an exterior layer and an interior layer connected to define a cavity which contains a dilatant fluid with a plurality of spheroids. The kinetic energy from HVP impact is dispersed by the plurality of spheroids and absorbed by the dilatant fluid. The plurality of spheroids within the cavity move to block a puncture hole in the shield.

  • Patent number: 10636347
    Abstract: A method of driving a pixel array includes providing a ramp signal to one or more columns of the pixel array. For each cycle of the ramp signal, the method further includes providing a first row driving signal to at least a first row of the pixel array and a second row driving signal to a second row of the pixel array. A pixel array driver may include a ramp signal generator configured to produce a ramp signal, a first amplifier configured to receive the ramp signal and produce a first amplified ramp signal, and a second amplifier configured to receive the ramp signal and produce a second amplified ramp signal. The first amplified ramp signal may be electrically connected to a first set of pixels of a pixel array, and the second amplified ramp signal may be electrically connected to a second set of pixels of the pixel array.

  • Patent number: 10580344
    Abstract: A method of scanning video information to a pixel array comprises, during a first active row interval, setting a column signal line to an initial voltage, asserting a first row signal line of the pixel array, setting the column line to a desired voltage, and de-asserting the first row signal line when the column signal line is at the desired voltage. The method further comprises, during a second active row interval occurring after an amount of time, setting the column signal line to the initial voltage, asserting the first row signal line of the pixel array, and de-asserting the first row signal line while the column signal line is at the initial voltage. The method further includes, during the second active row interval, asserting a second row signal line, and maintaining the assertion of the second row line for a period of time after de-asserting the first row signal line.

  • Publication number: 20070081291
    Abstract: A dissipator useful for discharging provides a continuously variable high-voltage load under control of a computer or other device capable of providing an analog control voltage. Known dissipator arrangements use multiple high voltage switches and resistors to attempt to dissipate power. However, the disclosed dissipator uses the resistive property of a matrix of photo resistive cells, typically cadmium sulphide arranged on a circuit board. These photo resistive cells are series connected and controlled optically to vary their resistances. An optical control signal is provided for each photo resistive cell by a corresponding light emitting diode (LED). The amount of light emitted by each LED is analog controlled.

  • Publication number: 20070018919
    Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system. The image is written to the the display therein causing the liquid crystal to move to a specific image position. A light source is flashed to illuminate the display. The pixel electrodes are set to a specific value to cause the liquid crystal to move towards a desired position. The process of writing, flashing, and setting the electrode intensity value to reorient the liquid crystal to produce an image is repeated.

  • Patent number: 5359153
    Abstract: This invention is directed to a clean-in-place, industrial floor scale having a removable deck and a weighing capacity up to about 5,000 pounds. The removable deck is fabricated from a nonmetallic material such as a polyethylene or polypropylene sheet, or a reinforced fiberglass and weighs less than about eighty pounds. The base frame of the scale is preferably stainless steel, and is also relatively lightweight, being about 140 pounds. One worker can lift and move the floor scale for daily sanitary cleaning when it is used in a food, chemical or pharmaceutical plant, without requiring a forklift, hoist or other motorized equipment.
