  • Patent number: 9898428
    Abstract: A method of generating column signals for use by a pixel array includes connecting two or more controllable bus buffers in series. The output of each of the two or more controllable bus buffers drives an associated node. The method further includes providing a column data signal to an input of the series-connected string of two or more controllable bus buffers. The method also includes sequentially enabling each controllable bus buffer in the series-connected string of two or more controllable bus buffers, such that each node is sequentially driven. Each node is electrically coupled to an input of an associated controllable local output buffer. The method further includes sequentially enabling each of the controllable local output buffers in an order associated with the sequentially enabling of the controllable bus buffers.

  • Publication number: 20180040334
    Abstract: Systems and apparatuses are described to automatically balance acoustic channel sensitivity. A computer readable medium containing executable computer program instructions, which when executed by an acoustic signal processing system, cause the acoustic signal processing system to perform a process that includes calculating a long-term power level of a main acoustic signal to obtain an averaged main acoustic signal. Segments of the main acoustic signal are excluded from the averaged main acoustic signal using a desired voice activity detection signal. A long-term power level of a reference acoustic signal is calculated to obtain, an averaged reference acoustic signal. Segments of the reference acoustic signal are excluded from the averaged reference acoustic signal using the desired voice activity detection signal. An amplitude correction signal is created using the averaged main acoustic signal and the averaged reference acoustic signal.

  • Patent number: 9886231
    Abstract: A handheld wireless display device, having at least SVGA-type resolution, includes a wireless interface, such as Bluetooth™, WiFi™, Wimax™, cellular or satellite, to allow the device to utilize a number of different hosts, such as a cell phone, personal computer, media player. The display may be monocular or binocular. Input mechanisms, such as switches, scroll wheels, touch pads, allow selection and navigation of menus, playing media files, setting volume and screen brightness contrast, activating host remote controls or performing other commands. The device may include MIM diodes, Hall effect sensors, or other position transducers and/or accelerometers to detect lateral movements along and rotational gestures around the X, Y and Z axes as gesture inputs and movement queues. These commands may change pages, scroll up, down or across an enlarged screen image, such as for web browsing.

  • Patent number: 9830909
    Abstract: A speech recognition method and system enables user-configurable speech commands. For a given speech command, the speech recognition engine provides a mechanism for the end-user to select speech command terms to use in substitution for the given speech command. The speech recognition engine, or module thereof, forms a replacement command for the given speech command from the user-selected speech command terms. The speech recognition engine thereafter is synonymously responsive to user utterance of the replacement command as though the user issued/voiced the associated counterpart given speech command.
