Abstract: Techniques described herein generally include methods and systems related to a MEMS-based audio speaker system configured with multiple speaker devices to generate an audio signal that is substantially without a high-band ultrasonic signal.

One modulator may implement a first modulation function on the acoustic carrier signal to generate a first audio signal, where the first modulation function may be based on a target acoustic output signal for the MEMS-based audio speaker system. The second modulator may implement a second modulation function on the acoustic carrier signal to generate a second audio signal, where the second audio signal may be the Hilbert transform of the first audio signal.

Abstract: Technologies are generally described for distribution of video over time-varying channels. A video processing module may encode a stream of video frames into a number of groups-of-pictures (GOPs), each GOP including multiple sub-groups-of-pictures (sub-GOPs) that may each be relatively self-contained. The video processing module may divide the encoded video frames into different blocks, and may assign different priorities to the different blocks based on how important the individual blocks are to the reconstruction of a sub-GOP, a GOP, or the stream of encoded video frames, including alternative blocks that make each sub-GOP entirely self-contained for the purpose of decoding in the event of severe losses of blocks from previous sub-GOPs. The video processing module may then provide the blocks to a client device based on the priority of the blocks, the connection quality of the client device, and occurrence of previous losses, for example.

Abstract: Technologies are generally described to provide alternate user interfaces based on user context. In some examples, a user interface system may measure a user characteristic associated with a particular user interface type. The user interface system may then determine whether the measured user characteristic is suitable for use as a user interface input, for example by comparison with a baseline user characteristic. Upon determination that the measured user characteristic is suitable, the user interface system may use the measured user characteristic for user interface purposes. On the other hand, upon determination that the measured user characteristic is not suitable, the user interface system may use a different user interface type to attempt to receive user inputs.
