  • Patent number: 9667280
    Abstract: Certain aspects of the present disclosure relate to a technique for touch temperature management of a wireless communications device based on power dissipated over time, and possibly internal temperature readings. For example, the information about power dissipated over time can be utilized along with monitored internal temperatures of a device's internal circuitry to reduce transmit power and/or data rates as required in order to keep a surface temperature of the wireless device below a specified limit. A knowledge of how the device's touch temperature varies with the dissipated power and a knowledge of the power dissipation history can be utilized to determine when to reduce the transmit power in order to avoid overheating (e.g., exceeding the touch temperature limit).

  • Patent number: 9654609
    Abstract: An accessory device having multiple speakers and/or microphones to perform a number of audio functions, for use with mobile devices, are provided. The audio transducers (e.g., microphones and/or speakers) may be housed in one or more extendable and/or rotationally adjustable arms. To compensate for the unwanted signal feedback between the speakers and microphones, acoustic echo cancellation may be implemented to determine the proper distance and relative location between the speakers and microphones. Acoustic echo cancellation removes the echo from voice communications to improve the quality of the sound. The removal of the unwanted signals captured by the microphones may be accomplished by characterizing the audio signal paths from the speakers to the microphones (speaker-to-microphone path distance profile), including the distance and relative location between the speakers and microphones.

  • Patent number: 9232071
    Abstract: Mobile communication devices, having multiple speakers and/or microphones to perform a number of audio functions, for use with mobile devices, are provided. The microphones may be housed within the communication device housing. To compensate for the unwanted signal feedback between the speakers and microphones, acoustic echo cancellation may be implemented to determine the proper distance and relative location between the speakers and microphones. Acoustic echo cancellation removes the echo from voice communications to improve the quality of the sound. The removal of the unwanted signals captured by the microphones may be accomplished by characterizing the audio signal paths from the speakers to the microphones (speaker-to-microphone path distance profile), including the distance and relative location between the speakers and microphones. The optimal distance and relative location between the speakers and microphones is provided to the user to optimize performance.

  • Publication number: 20100259458
    Abstract: An apparatus includes an azimuth adjuster coupled between a motor and a directional antenna. Motor rotation causes the azimuth adjuster to rotate the antenna about an azimuthal axis. The motor rotation also causes an elevation adjuster to rotate, which causes a screw mechanism to modify an elevation angle by pivoting the antenna about an elevational axis. To aim the directional antenna, a body-direction vector of a movable body with the antenna attached thereto is determined. Based on an elevational relationship between the body-direction vector and a satellite-direction vector, the elevation adjuster modifies the elevation angle of the antenna by rotating the motor to achieve full-turn amounts to pivot the antenna. The azimuth adjuster modifies an azimuth angle of the antenna based on an azimuthal relationship between the body-direction vector and the satellite-direction vector by rotating the motor to achieve partial-turn amounts of the antenna.
