  • Patent number: 10070211
    Abstract: The invention is a multi-microphone voice processing SoC primarily for head worn applications. It bypasses the use of conventional pre-amp voice CODEC (ADC/DAC) chips all together by replacing their functionality with digital MEMS microphone(s) and digital speaker driver (DSD). Functionality necessary for speech recognition such as noise/echo cancellation, speech compression, speech feature extraction and lossless speech transmission are also integrated into the SoC. One embodiment is a noise cancellation chip for wired, battery powered headsets and earphones, as smart-phone accessory. Another embodiment is as a wireless Bluetooth noise cancellation companion chip. The invention can be used in headwear, eyewear glass, mobile wearable computing, heavy duty military, aviation and industrial headsets and other speech recognition applications in noisy environments.

  • Patent number: 10013976
    Abstract: In headset computers that leverage voice commands, often the user does not know what voice commands are available. In one embodiment, a method includes providing a user interface in a headset computer and, in response to user utterance of a cue toggle command, displaying at least one cue in the user interface. Each cue can correspond to a voice command associated with code to execute. In response to user utterance of the voice command, the method can also include executing the code associated with the voice command. The user can therefore ascertain what voice commands are available.

  • Patent number: 9941895
    Abstract: Systems and methods are described to time delay a signal output from an analog-to-digital converter (ADC). The ADC includes a digital sensor responsive to an analog field quantity. The digital sensor is configured to output an oversampled digital output signal at a sampling clock frequency. A time delay element is configured to receive as an input, the oversampled digital output signal and to output a time delayed oversampled digital output signal. A filter is configured to receive as an input the delayed oversampled digital output signal. The filter low pass filters and decimates to a lower sample rate the delayed oversampled digital output signal. An output includes a low pass filtered decimated delayed digital output signal, where the lower sample rate is less than the sampling clock frequency.

  • Patent number: 9934739
    Abstract: A display driver includes a symbology generator having an electronic architecture optimized for symbology display, along with an interface to a microdisplay. The interface is configured to operatively couple the symbology generator to the microdisplay, to support a display of symbol objects on the microdisplay. The symbology generator may be a one-bit symbology generator configured to provide bi-level pixel data representing symbology to the microdisplay. The symbology generator may be configured to provide video information to the microdisplay in addition to the bi-level pixel data. The symbology generator may be further configured to coordinate the bi-level pixel data with the video information. The coordination may include various types of blending of the symbology data and the video data, or a hybrid mode where symbology data is applied to one set of pixels of the microdisplay, and video data is applied to another set of pixels of the microdisplay.

  • Patent number: 9915812
    Abstract: A compact display module, such as can be used in wearable computing headset applications, includes a microdisplay with a display surface that is virtually imaged by a lens. The lens is positioned to receive light from the display surface of the microdisplay. The lens defines an angled fold, whereby light from a display generated at the display surface is reflected within the lens to thereby form a virtual image of the display in a virtual image plane that is angled non-perpendicularly relative to the display surface of the microdisplay.

  • 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. An embedded software driver permits replicating a high-resolution screen display from a host PC.

  • 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.
