A system that incorporates teachings of the subject disclosure may include, for example, a controller that determines a radiated throughput for at least one of an uplink throughput or a downlink throughput of the communication device, reduces transmit power for the communication device responsive to the radiated throughput satisfying a predetermined throughput range, and tunes a matching network of the communication device responsive to the radiated throughput not satisfying the predetermined throughput range. Other embodiments are disclosed.

Method and apparatus for antenna tuning and power consumption management in a communication device

Broadly speaking, the technology relates to using wave field synthesis theory to simulate one or more idealized virtual point sources in a multi-speaker system. The speaker transfer function of each speaker is modeled, and the values and directional gradient of the combined speaker transfer function at test points in a convexly-bounded listening region are compared to the desired values and directional gradient for the idealized transfer function of the idealized virtual point source(s) at the test points to determine filter coefficient sets for each filter. The determined filter coefficients are those which minimize the total difference between the values and directional gradient of the combined speaker transfer function and the values and directional gradient of the idealized transfer function of the idealized virtual point source across all the test points for a plurality of frequency bins.

Wave field synthesis by synthesizing spatial transfer function over listening region

A device operable using touch-less and touchscreen gestures and a method and system to operate the device are described. The device includes two or more ambient light sensors arranged at respective surface locations of the device and sensing light intensity at the respective surface locations. The device also includes a processor coupled to the two or more ambient light sensors to identify a touch-less gesture based on the light intensity sensed by the two or more ambient light sensors, receive a touchscreen gesture, and operate the device based on the touch-less gesture and the touchscreen gesture.

Operating a device using touchless and touchscreen gestures

A system that incorporates teachings of the subject disclosure may include, for example, a controller that determines a radiated throughput for at least one of an uplink throughput or a downlink throughput of the communication device, reduces transmit power for the communication device responsive to the radiated throughput satisfying a throughput threshold, and tunes a matching network of the communication device responsive to the radiated throughput not satisfying the throughput threshold. Other embodiments are disclosed.
