  • Publication number: 20170206057
    Abstract: A method or apparatus for multi-channel audio data control using plural mobile devices comprising steps of detecting user presence through assigned frequency, transmitting audio data to the nearest device from the user based on user presence information, and recognize user gesture to control the audio data. A remote controller held by the user may also have a priority to control audio data.

  • Patent number: 7420412
    Abstract: A multiple power mode amplifier provides a low and a high power mode without using switches. This amplifier may be used in radio frequency (RF) applications such as mobile telephones, pagers, portable digital assistants, and wireless e-mail devices. In the low power mode, the power consumption of the amplifier is reduced, which will increase operation time, especially important for battery-operated devices. In one implementation, the amplifier includes a number of impedance matching network units (130, 140, 150, and 160), impedance transformer (170), and a power stage (120). An implementation provides further power consumption savings by modulating a bias of an amplifier stage.
