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 internal forces or both the internal forces and an external force 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 the external force applied to the touch sensor, wherein the internal forces exist in the touch sensor before applying the external force, and the calibrator is configured to remove the contribution of the internal forces from the non-calibrated signal using the configurable control signal when the external force is applied or not applied to the touch sensor.

Abstract
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. The apparatus also comprises 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.
