Abstract: A system may include a sensor configured to output a sensor signal indicative of a distance between the sensor and a mechanical member associated with the sensor, a measurement circuit communicatively coupled to the sensor and configured to determine a physical force interaction with the mechanical member based on the sensor signal, and a compensator configured to monitor the sensor signal and to apply a compensation factor to the sensor signal to compensate for changes to properties of the sensor based on at least one of changes in a distance between the sensor and the mechanical member and changes in a temperature associated with the sensor.

Abstract: A system may include a tactile actuator for providing tactile feedback and a resonant phase sensing system. The resonant phase sensing system may include a resistive-inductive-capacitive sensor and a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and the tactile actuator. The resistive-inductive-capacitive sensor may be configured to measure phase information associated with the resistive-inductive-capacitive sensor, based on the phase information, detect an indication of human interaction with the system proximate to the resistive-inductive-capacitive sensor, and trigger the tactile actuator to generate tactile feedback responsive to detecting the indication of human interaction.
