  • HIGH VOLTAGE DRIVING USING TOP PLANE SWITCHING WITH ZERO VOLTAGE FRAMES BETWEEN DRIVING FRAMES
    Publication number: 20240169942
    Abstract: Improved methods for driving an active matrix of pixel electrodes controlled with thin film transistors when the voltage on a top electrode is being altered between driving frames. The methods described increase performance by providing smaller swings in the overall voltage between the top electrode and pixel electrode while reducing stress on the thin film transistor.

  • Sub-threshold addressing and erasing in a magneto-electrophoretic writing medium
    Patent number: 11934593
    Abstract: A magneto-electrophoretic medium that can be globally and locally addressed and erased. The medium provides a writeable display with no perceivable lag and the ability to write and erase with only minimal power requirements. In particular, the magneto-electrophoretic medium can be erased by providing a subthreshold electric stimulus and supplementing a second non-electric stimulus that disturbs the written state and allows the magneto-electrophoretic particles to return to their original state.

  • AUTOMATED WILDFIRE PREVENTION AND PROTECTION SYSTEM FOR DWELLINGS, BUILDINGS, STRUCTURES AND PROPERTY
    Publication number: 20180063529
    Abstract: A fire retardant delivery system for use with a source of carrier for protection from wildfire is provided. The system includes a retardant tank for storing a fire retardant. The retardant tank is in fluid communication with the source of carrier. A metering valve is constructed and arranged to meter a flow of fire retardant injected into the carrier discharged from the source of carrier to maintain a predetermined proportion of fire retardant to carrier, thereby creating a fire retardant and carrier mixture. At least one distribution nozzle is configured to deliver the fire retardant and carrier mixture to a desired area.
