  • Mobile wireless communications device with orientation sensing and related methods
    Patent number: 8351894
    Abstract: A mobile wireless communications device may include a housing, a wireless transceiver carried by the housing, and a display carried by the housing. The mobile wireless communications device may further include a non-visual indicator carried by the housing, and an orientation sensor carried by the housing. A controller may be carried by the housing, and coupled to the wireless transceiver and the display to perform at least one mobile wireless communications function. The controller may also be switchable to a stabilization mode to activate the non-visual indicator based upon the orientation sensor sensing relative angular movement beyond a threshold.

  • Audio peripheral for an electronic device
    Patent number: 7561711
    Abstract: A peripheral for an electronic device having a speaker is provided. The peripheral includes an input device for placement proximal to the speaker for receiving audio information from the speaker. The peripheral includes an output device connected to the input device that is positioned distal from the input device and away from electromagnetic signals generated by the device. The output device presents the audio information to a hearing aid proximal to the output device. The output device is positioned at a distance such that the electromagnetic signals experienced by the input device is less than the signals experienced by the hearing aid. As a result, deleterious effects of signals otherwise experienced by the hearing aid are reduced.
