Abstract: 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.

Abstract: 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.

Abstract: A small closed loop antenna is formed by a flat metal member formed into a U-shape which also serves as the front, back and top surfaces, or parts thereof, of the housing for a portable communications receiver. Connected to the open (bottom) end of the arms is an isolation network providing an optimum antenna ground and a reactance network which applies a capacitive reactance across the antenna and isolation network so that the conductive member forms an antenna that detects the H-field of the electromagnetic wave to be received. The reactance network is tunable to adjust the antenna for reception at particular frequencies.
