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: 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.
