Abstract: A mobile computing device comprises a power source, a display, a display driver and a control circuit. The power source is configured to provide a power signal. The display comprises a plurality of pixels. The display driver is configured to receive the power signal and to drive the pixels based on the power signal and display data. The control circuit is configured to periodically remove the power signal from at least a portion of the display driver.

Abstract: Various embodiments are directed to systems and techniques for reducing power consumption in a mobile computing device. In one or more embodiments, a mobile computing device may be arranged to determine a user environment based on detected antenna impedance or detected current. After the user environment is determined, the mobile computing device may confirm that total radiation power (TRP) for the mobile computing device at an initial conducted power level exceeds the minimum TRP threshold required by the network carrier to receive acceptable quality of service (QoS). Based on the excess TRP for the particular user environment, the mobile computing device may determine a reduced conducted power level to be input to an antenna system. Accordingly, significant power savings may be achieved. To save additional power, the mobile computing device may automatically adjust and/or improve antenna impedance matching based on user environment allowing a further reduction in conducted power.

Abstract: A mobile computing device comprises a printed circuit board, a processing circuit, a surface mount microphone, and a vibration attenuation portion. The processing circuit is disposed on a first portion of the printed circuit board. The surface mount microphone is disposed on a second portion of the printed circuit board. The vibration attenuation portion of the board is configured to attenuate vibrations from the first to the second portion of the printed circuit board.

Abstract: A device such as a mobile phone includes a device to be hearing aid compatible. The device may include a first speaker for private listening operation and a second speaker that provides both speakerphone operation and hearing aid (e.g. telecoil) operation. The device may include a first use position for normal listening and a second, substantially different, use position for telecoil operation.
