摘要： A method and apparatus for automatic resonance detection is disclosed for a motor-driven mechanical system such as a voice coil motor (VCM) in which a resonance detector and driver are provided. The automatic resonance detector may be implemented on the same integrated circuit as the driver, and dynamically determines the natural resonant frequency of the VCM driven by the driver. The resonant frequency is determined by measuring the back electromotive force (BEMF) of the VCM, detecting the slope of the BEMF signal, and determining the resonant frequency from the slope of the BEMF signal.

摘要： A method and a device for detecting user input includes receiving a user input at an input arrangement of a user interface. The input arrangement has at least one piezoelectric sensor that generates an electric signal in response to the input. The electric signal is processed to determine the presence of the input. The processing may indicate the magnitude of the force of the input, in addition to the input's location. An output arrangement of the user interface generates an output in response to the processing. The output may be a haptic, audio or visual output.

摘要： A tilt sensor having a printed circuit board disposed in a direction normal to a reference plane for measuring a tilt angle with a pair of electrodes formed on a first surface of the printed circuit board. A cover is affixed to the printed circuit board and creates a cavity between the cover and the printed circuit board with a predetermined gap between the cover and the pair of electrodes, the cover acting as a common electrode to the pair of electrodes to create a pair of capacitors. An inert liquid is contained in the cavity, the surface level of the inert fluid varying according to the tilt angle of the reference plane. A signal processing circuit is formed on a second surface of the printed circuit board that produces an output signal corresponding to a difference in capacitance between the two capacitors as a tilt angle detection output.
