  • Patent number: 12271544
    Abstract: The present disclosure relates to a method and a device for measuring a force action. The disclosure additionally relates to an input apparatus which uses such a device or such a method. In a first step, a voltage pulse resulting from a force action on a force sensor is generated by a charge amplifier. Using this voltage pulse, a trigger pulse may be generated by a comparator circuit. A voltage value derived from the voltage pulse is then stored in a storage capacitor by a current mirror. The capacitor voltage resulting therefrom may be evaluated by an evaluation unit.

  • Patent number: 12242313
    Abstract: A system determines a current state of an information handling system, and receives a sensor output signal. The system determines whether a status change of the sensor output signal relates to an expected state based on the current state and a previous state of the information handling system, and determines whether the sensor output signal is triggered by an external magnet. If the status change of the sensor output signal relates to the expected state and the sensor output signal is not triggered by the external magnet, then the system transitions the information handling system from the current state to the expected state.
