    Abstract: Techniques for regulating a radio frequency (RF) output power of an antenna of a computing device are described. In an example a physical signal filter unit (PSFU) to filter a detection signal from a proximity sensor for regulating an RF output power of a device is described. The PSFU includes a first filter circuit to filter the detection signal and generate a first filter output signal and a logical inverter gate to generate an inverted detection signal based on the detection signal. The PSFU also includes a second filter circuit to generate a second filter output signal based on the inverted detection signal. The PSFU also includes a logical AND gate to perform a logical AND operation on the first filter output signal and the second filter output signal to generate a control signal for regulating the RF output power of an antenna of the computing device.

    Abstract: A technique includes detecting a finger pattern that is associated with a physical interaction of a user with a touch screen of an electronic device. The technique includes acquiring sensory input that is associated with the user other than a characteristic of the physical interaction of the user with the touch screen. The technique includes determining whether the physical interaction is associated with an intent to use the touchscreen for key-based input entry based at least in part on the sensory input and controlling a user interface for the electronic device based at least in part on the detected finger pattern and the determined intent.
