Abstract: A wireless transmitter (100) including an amplifier (112), an automatic output controller (116) (AOC) having an output coupled to a control signal input. The AOC detects a second amplifier parameter that changes with a change in load impedance during a transmission, and the AOC reduces a change in transmitter output power related to the change in load impedance based on a first parameter and the detected second parameter during the same transmission during which the second parameter was detected.

Abstract: A method (500) and apparatus (601) generate an input signal based on the orientation of a device. A sensor (302) such as a camera, a gyro, or an accelerometer detects a change in device orientation and generates a position input signal that is provided to an application program (612) such as a game program, a text messaging program, or a user interface program to affect an operation thereof. The input signal can, for example, affects a navigation position associated with the application program.

Abstract: A method of operating an amplifier, for example, in a wireless radio transceiver, including monitoring a characteristic of the amplifier during an operating interval of the amplifier, for example, during a transmission burst, providing an open-loop control signal to the amplifier during a subsequent operating interval of the amplifier wherein the open-loop control signal based on the characteristic monitored during a previous operating interval. In one embodiment, the corrected control signals are stored in a look-up table (510) that is updated based on the changes in load impedance.
