Patent number: 11935480Abstract: 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.Type: GrantFiled: May 29, 2021Date of Patent: March 19, 2024Assignee: KOPIN CORPORATIONInventor: Frederick Herrmann

Patent number: 11623769Abstract: 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.Type: GrantFiled: January 20, 2021Date of Patent: April 11, 2023Inventors: Andreas Olafsrud, Austin Pham, Christian Williams, Frederick Herrmann

Publication number: 20070081291Abstract: 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.Type: ApplicationFiled: September 26, 2006Publication date: April 12, 2007Inventors: Ricky Curl, Frederick Herrmann

Publication number: 20070018919Abstract: 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.Type: ApplicationFiled: June 26, 2006Publication date: January 25, 2007Inventors: Matthew Zavracky, Frederick Herrmann, Wen-Foo Chern, Alan Richard, Ronald Gale, Jason Lo, David Ellertson, Kuojinng Tsai, John Fan, Bor-Yeu Tsaur, Stephen Pombo, Rodney Bumgardner, Duy-Phach Vu

Patent number: 5359153Abstract: 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.Type: GrantFiled: June 2, 1993Date of Patent: October 25, 1994Assignee: Indiana Scale Co., Inc.Inventors: Frederick Herrmann, Gregory A.
