    Abstract: Head-wearable apparatus to generate binaural audio content includes a first stem coupled to a first microphone housing that encases first front microphone and first rear microphone that generates acoustic signals, respectively. First microphone housing includes a first front port that faces downward and a first rear port that faces backwards. Apparatus includes second stem coupled to second microphone housing that encases second front microphone and second rear microphone that generate acoustic signals, respectively. Second microphone housing includes second front port that faces downward and second rear port that faces backwards. Apparatus includes binaural audio processor that includes beamformer and storage device. Beamformer generate first beamformer signal based on acoustic signals from first front microphone and first rear microphone, and second beamformer based on acoustic signals from second front microphone and second rear microphone. Storage device stores first and second beamformer signals as a two-channel file.

    Abstract: Camera compensation methods and systems that compensate for misalignment of sensors/camera in stereoscopic camera systems. The compensation includes identifying a pitch angle offset between a first camera and a second camera, determining misalignment of the first and second cameras from the identified pitch angle offset, determining a relative compensation delay responsive to the determined misalignment, introducing the relative compensation delay to image streams produced by the cameras, and producing a stereoscopic image on a display from the first and second image streams with the introduced delay.

    Abstract: Systems and methods for managing temperatures of wearable device components are disclosed. In one aspects, a method includes determining a temperature of an electronic component of the wearable device, determining a rate of temperature change of the electronic component, and determining whether to increase or decrease a transmission rate limit of the electronic component based on the temperature and the rate, adjusting the transmission rate limit based on the determination, and limiting a rate of transmission of the electronic component based on the adjusted transmission rate limit.

    Abstract: A RF wireless charging enclosure configured to enable efficient wireless charging of a CE device in the enclosure while also allowing wireless communication of the CE device to devices outside the enclosure. In one example, time multiplexing is used such that the CE device is enabled to either be charged, or to communicate with a device outside the enclosure. In another example, frequency division is used such that the CE device is charged at a first frequency, and simultaneously communicates through the enclosure at a second different frequency.
