Abstract: A system includes a first matching network having a first impedance and a second matching network having a second impedance, where the second impedance is different than the first impedance. The system further includes a switching connector having first and second switching positions, where when the switching connector is in the first switching position an input terminal is connected through the first matching network to a first antenna and where when the switching connector is in the second switching position the input terminal is connected through the second matching network to a second antenna and the first antenna is connected to ground.

Abstract: A device may obtain samples from an accelerometer and a gyroscope, determine kinematics signals based on the samples, and compute a number of steps taken by a user based on the kinematics signals.

Abstract: A device may include an amplifier to receive an input signal, amplify the input signal to produce an output signal, and send the output signal to a destination. The device may include a processing module to process feedback information related to the input signal and the output signal to generate a result that is used to distort input signals for input to the amplifier, wherein the distorted input signals account for distortion produced by the amplifier.
