  • Patent number: 10049656
    Abstract: Features are disclosed for generating predictive personal natural language processing models based on user-specific profile information. The predictive personal models can provide broader coverage of the various terms, named entities, and/or intents of an utterance by the user than a personal model, while providing better accuracy than a general model. Profile information may be obtained from various data sources. Predictions regarding the content or subject of future user utterances may be made from the profile information. Predictive personal models may be generated based on the predictions. Future user utterances may be processed using the predictive personal models.

  • Patent number: 10019386
    Abstract: One or more characteristics of devices are ascertained in accordance with one or more aspects of the disclosure. As may be consistent with one or more embodiments, the attachment of an external circuit to an input port is detected based on a resistance value presented by the external circuit. A resistance range that includes the resistance value presented at the input port is determined, in response to detecting the attachment, by dynamically coupling one or more of a plurality of resistor-based circuits relative to the input port. A signal presented by the external circuit on the input port is coded based on the determined resistance range, using one or more of the resistor-based circuits, and the code is used to identify a type of the external circuit. These aspects can provide for the communication of power and data with a variety of different types of external circuits.

  • Patent number: 9698786
    Abstract: Aspects of the present disclosure are directed to detecting and powering external circuits via a common port. As may be implemented in accordance with one or more embodiments, an accessory detection circuit detects a type of an external circuit based upon a pull-down resistance at an interface port (e.g., where each accessory type provides a discernable pull-down resistance). Power switching circuitry couples power between the interface port and an internal power-based circuit, and operates in an open condition when the accessory detection circuit is active. An adaptive biasing circuit sets a voltage across the power switching circuitry to about zero, based on a voltage level provided on the interface port, thereby mitigating changes in the pull-down resistance due to current leakage. Once the type of external circuit is identified, the power switching circuitry couples power between the external circuit and the internal circuit.

  • Publication number: 20170115711
    Abstract: A protocol can specifie a power-sourcing voltage range that indicates power sourcing capabilities. Additional power sourcing capabilities can be communicated using voltage variations within the power-sourcing voltage range. A power-sourcing device can provide power to an external power-sinking device over a wired connection containing a plurality of wires. A voltage control circuit can be configured to drive a voltage over a wire of the plurality of wires. Processing circuitry can communicate, using the voltage control circuit, first power-sourcing capabilities to the external power-sinking device by setting the voltage over the wire to a value within the power-sourcing voltage range. The processing circuitry can also communicate, using the voltage control circuit, the additional power sourcing capabilities of the power-sourcing device using voltage variations on the wire, the voltage variations maintaining voltage on the wire within the power-sourcing voltage range.

    Abstract: Various aspects of the disclosure are directed to methods and apparatuses involving providing a clock signal. As consistent with one or more embodiments herein, a sawtooth waveform signal is generated in a manner that facilitates low power operation. In some implementations, the sawtooth waveform signal is generated using an oscillator that operates without necessarily employing R-C circuits and/or without rail-to-rail voltage supply, such as via a nonlinear oscillator. The sawtooth waveform signal is used to generate a trapezoidal waveform signal, and a clock signal is generated using the trapeziodal waveform signal.

  • Publication number: 20160250646
    Abstract: A treaded lifter bar (1) for grinding mill is provided with a plurality of flexible treads (2) positioned over the core rubber matrix forming its main rubber surface. Treads (2) have a zig-zag configuration with higher rubber content in their wear zone to increase the surface area and reduce the wearing lifter bar (1). The treads (2) primarily absorb the impact force (3a) of slurry (4) and dissipate the heat generated due to impact. The slurry (4) is deposited on top of the treads (2) thus protecting the treads (2) from direct contact with the slurry (4) to ensure less wear. The zig-zag configuration of the top wearing treads (2) of the treaded lifter provides increased wear volume.
