  • Patent number: 9760194
    Abstract: Embodiments of the present invention generally provide a processing system for a display device having an integrated sensing device. The processing system includes a driver module that includes driver circuitry, the driver module coupled to source lines and sensor electrodes. Each sensor electrode including one or more common electrodes configured for display updating and input sensing. The driver module is configured to select a first display line for display updating during a first display update period, drive the sources lines with first display update signals during the first display update period to update the first display line, drive a first sensor electrode of the plurality of sensor electrodes for capacitive sensing during a non-display update period, and operate the source lines in a restore mode during a restart period, wherein the restart period is after the non-display update period and before a second display update period.

  • Patent number: 9576557
    Abstract: Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving common electrodes corresponding to pixels in a display line. In general, the input devices drive each electrode until each display line (and each pixel) of a display frame is updated. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a proximity sensing area. To do this, the input device may interleave periods of capacitive sensing between periods of updating the display based on a display frame. For example, the input device may update the first half of display lines of the display screen, pause display updating, perform capacitive sensing, and finish updating the rest of the display lines. Further still, the input device may use common electrodes for both updating the display and performing capacitive sensing.

  • Patent number: 9128713
    Abstract: Embodiments of the invention generally provide an input device that includes one or more source drivers that are coupled to a display screen. Specifically, one of the source drivers may be coupled to a plurality of source lines (or column lines) on the display screen which the source driver uses to set voltages associated with one or more sub-pixels that determine the color displayed by the pixel. When driving voltages onto subsequent source lines, the input device may precharge the source driver using a latent voltage stored on the source lines. That is, if the source line was previously driven to a particular voltage by the source driver, the input device uses that latent voltage to precharge the output of the source driver to the same voltage. The source driver may then adjust its output to a desired voltage and drive the desired voltage onto the source line and sub-pixel.

  • Patent number: 8794152
    Abstract: A gas-impermeable sealer element (24, 124) for a detonator or other explosive initiation device includes a non-reactive sleeve (26, 126) having a channel (28, 128) formed therein. A reactive material strip (30, 130) is sealed within the channel for transmission of an explosive's initiation signal through the sealer element (24, 124), either alone or in cooperation with transfer charges located at the input and/or output end of the non-reactive sleeve (26, 126). The reactive material strip (30, 130) comprises a reactive metal wire or other substrate (34) having on one or both sides thereof a layer of reactive material (30, 130, 36), either reactive metal foils which react exothermically when ignited, or a deposited fuel-oxidizer reactive material. The reactive materials, upon being energized, react exothermically in the absence of atmospheric oxygen or other extraneous oxidizer and so may be encapsulated, sealed or otherwise isolated from the atmosphere in use.

  • Patent number: 8245643
    Abstract: A delay unit (10) comprises a timing strip (14) and, optionally, a calibration strip (20) deposited on a substrate (12). The timing and calibration strips comprise energetic materials which optionally may comprise particles of nanosize materials, e.g., a fuel and an oxidizer, optionally applied as separate layers. A method of making the delay units comprises depositing onto a substrate (12) a timing strip (14) having a starting point (14d) and a discharge point (14e) and depositing onto the same or another substrate a calibration strip (20). Timing strip (14) and calibration strip (20) are of identical composition and are otherwise configured, e.g., thickness of the strips, to have identical burn rates. The calibration strip (20) is ignited and its burn rate is ascertained.

  • Patent number: 8033222
    Abstract: A connector clip (10, 10?) defines a line-retaining slot (34) and is configured to receive a detonator (16) therein. The connector clip (10, 10?) comprises a body member (12, 12?) and a closure member (14, 14?) which are mounted, one on the other, for movement relative to each other along a travel path between an open position in which the line-retaining slot (34) is accessible to lateral insertion therein of one or more signal transmission lines (68), and a closed position in which the line-retaining slot (34) is closed to secure such signal transmission lines (68) therein. One of the body member (12, 12?) and the closure member (14, 14?) defines a cavity within which at least part of the other of the body member (12, 12?) and the closure member (14, 14?) is encased during travel between the open position and the closed position.
