Abstract: Digitized audio command is decoded to generate audio features. An in-domain confidence score is calculated for a model trained by a limited set of peripheral device commands. An out-domain confidence score is calculated for a model trained without the peripheral device commands. The best score determines whether to process the audio locally or at a remote server. In some embodiments, a likelihood ratio (LR) is calculated of the in-domain and out-domain confidence scores. Based on the likelihood ratio, a locally decoded audio command is performed, or the audio features are sent to a remote server for processing to determine the audio command.
Abstract: A computer-implemented method includes receiving first and second movement data corresponding to a movement of a first and second computer mouse, respectively, wherein the first and second computer mice are oriented in a same direction are moving in unison over a same trajectory while the first and second movement data is contemporaneously received; determining a movement distance for the first and second computer mice based on the first and second movement data, respectively; determining a performance characteristic for the first computer mouse based on the determined first movement distance; determining the performance characteristic for the second computer mouse based on the determined second movement distance; determining a difference in the performance characteristic for the first computer mouse with respect to the second computer mouse; and calibrating the performance characteristic of the second computer mouse to match the performance characteristic of the first computer mouse.

Abstract: An input device comprising a processor(s), an input element, an electropermanent magnet (EPM) assembly including: a permanent magnet operable to generate a magnetic field; and a magnetizing assembly configured to set a magnetic field generated by the permanent magnet, a first ferromagnetic element, and a second ferromagnetic element. The first ferromagnetic element is configured to part and move away from the second ferromagnetic element as the input element is depressed. When the EPM assembly magnetizes the permanent magnet to a first polarity, the first and second ferromagnetic elements are magnetically attracted to each other and provide an attracting that magnetically opposes the first and second ferromagnetic elements from parting, and when the EPM assembly magnetizes the permanent magnet to a second polarity, the first and second ferromagnetic elements are not magnetically attracted to each other and do not magnetically oppose the first and second ferromagnetic elements from parting.

Abstract: A method and system configured to receive a first report from a computer peripheral device by a receiver, determine that the first report is corrupted or received at a rate slower than the first report rate, compute a current trajectory of the computer peripheral device based on one or more intervals of movement data in the first report, compute a predicted trajectory of the computer peripheral device based on the first report, compute an incremental displacement of the computer peripheral device based on the predicted trajectory. The method and system can further generate data indicative of a position or displacement of the computer peripheral device based on the predicted trajectory of the computer peripheral device and send the data indicative of a position or displacement of the computer peripheral device at an interval that is less than twice a period of the first report rate to the host computing device.

Abstract: A microphone system includes a microphone and a pre-amplification conditioning circuit configured within a housing and comprising a pair of matched JFETs configured in a differential pair with common-source configuration and, when biased, are operable to receive and amplify the differential microphone output signal. The microphone further includes a pair of BJTs configured as a complimentary feedback transistor pair with each of the pair of BJTs coupled in parallel to a corresponding one of the pair of matched JFETs, and a current sink coupled to the matched JFETs and corresponding emitter electrodes of the BJTs and operable to maintain a fixed total direct current through each of the matched JFETs and BJTs, which reduces the JFETs corresponding electrical load, reduces signal noise, and increases a maximum amplified microphone output signal level at the drains of the matched JFETs.

Abstract: Some embodiments include a method comprising receiving gaze data from an image sensor that indicates where a user is looking, determining a location that the user is directing their gaze on a display based on the gaze data, receiving a confirmation input from an input device, and generating and effectuating an input command based on the location on the display that the user is directing their gaze when the confirmation input is received. When a bystander is in a field-of-view of the image sensor, the method may further include limiting the input command to be generated and effectuated based solely on the location on the display that the user is directing their gaze and the confirmation input and actively excluding detected bystander gaze data from the generation of the input command.
Abstract: This present disclosure describes a system and methods for encoding optimization in streaming multimedia. At least one method includes training an optimization engine to discover the optimal encoding settings for a specific type of content; a user playing video games or content on a computer, using streaming software to combine all or part of their computer session with their local camera feed, the streaming software retrieving a graphical overlay for insertion into the video, the streaming software encoding the video using encoder settings optimized to the video game or content being played, and the streaming software publishing the encoded video to one or more streaming services for viewers to consume.
Abstract: A system can include a serial, full-duplex, synchronous peripheral communication interface composed of four communication lines that communicatively couple a host processor to an optical sensor, the four communication lines including: a clock (CLK) line; a chip select (CS) line; a host output (MOSI) line; and a sensor output (MISO) line, the MISO line operating according to the following conditions when the CS line is selected: provide a service register data indicating when one or more predetermined conditions have occurred prior to receiving any commands from the host processor; provide a state register data defining the one or more predetermined conditions that occurred; and in response to receiving a command from the host processor received after the service register data and state register data is provided, the command requesting input device operational data, provide the operational data to the host processor.
Abstract: A peripheral device for a computing system comprises an electrical switch and a user depressible button. An electrostatic brake is attached to the user depressible button and controls a force profile of the keystroke of the user depressible button. The button is coupled to and is configured to actuate the electrical switch at the end of the keystroke. A movable electrode is coupled to the depressible button and a stationary electrode is positioned parallel to and proximate the movable electrode. A dielectric material is positioned between the movable electrode and the stationary electrode forming an electrostatic brake. An electrical circuit is coupled to the first and the second electrodes and is configured to apply a voltage potential between the first and the second electrodes to apply a resistive force to the depressible button.
