Abstract: The structural rigidity of a device is improved by overmolding one or more layers of the device housing over the antenna components, improving overall wall thickness and avoiding air gaps present in conventional devices. Pull tabs are implemented for battery installation and removal using a stretch-release adhesive connected to the tabs that can hold the battery in place and, upon pulling of the pull tabs, cause the battery to be removable from the device. Camera sensors larger than the camera optics are usable in a device by utilizing only image data captured by those pixels of the sensor that correspond to the appropriate part of the camera optics. Mechanical interlocks can be used advantageously for alignment and connection strength for side soldering. Optical alignment processes are used advantageously in situations such as mounting a device camera relative to an opening of a light absorbing layer on a cover glass sheet.

Abstract: Aspects disclosed herein relate to providing peer communications between NFC enabled devices using an active communication mode. In one example, a communications device is equipped to detect a remote NFC device field within an operating volume, establish a peer communication link with the remote NFC device using an active communication mode, determine that the peer communication link is to be deselected, and transmit a deselection request message to the remote NFC device indicating to the remote NFC device that it has been deselected while maintaining the peer communication link. In another example, a communications device is equipped to sense an operating volume, as part of an active communication mode collision avoidance procedure, determine that no field is sensed, initiate an unmodulated carrier as part of switching an operating field to an on state, and maintain the unmodulated carrier for a collision avoidance threshold duration of time.

Abstract: A method and apparatus for amplifying audio signals without exceeding an input current limit budgeted for the audio power amplifier circuit includes an intermediate energy storage between a battery and the audio power amplifier which provides an energy reserve to support amplifying peaks where the peaks have a peak power that is greater than the power that can be drawn from the battery due to the input current limit. Speech signals, which include substantial periodic content having short peaks relative to a pitch period, can be amplified without depleting the intermediate energy storage, allowing the intermediate energy storage to recover after a peak and before occurrence of a next peak. When an audio signal is amplified that results in depletion of the intermediate energy storage, a depletion recovery circuit reduces the overall audio gain to reduce the power demand of the audio power amplifier so as to substantially avoid distortion.
