1. Apparatus comprising:

  • one or more inputs configured to receive;

    a configurable control signal from a configurable signal generator; and

    a non-calibrated touch input signal from a touch sensor, said non-calibrated touch input signal generated by detecting both internal and external forces applied to the touch sensor; and

    a calibrator configured to process the non-calibrated touch input signal and the configurable control signal to remove the contribution of the internal forces from the non-calibrated signal to generate a calibrated signal, the calibrated signal for use in the detection of an external force applied to the touch sensor.
