Publication number: US20220029505A1
Application number: 17/497,110

Abstract:
A system for detecting displacement of a movable member of an electromagnetic transducer having a magnetic coil-driven linear actuator with a static member and a movable mass mechanically coupled to the static member and having a back electromotive force present across terminals of a coil of the electromagnetic transducer is provided. The system may include a resistive-inductive-capacitive sensor comprising the coil, a driver configured to drive the resistive-inductive-capacitive sensor with a driving signal, a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to measure one or more of phase information and amplitude information associated with the resistive-inductive-capacitive sensor and based on the one or more of phase information and amplitude information, determine a displacement of movable mass, wherein the displacement of the movable mass causes a change in an impedance of the resistive-inductive-capacitive sensor.

Publication number: US20220026989A1
Application number: 17/495,277

Abstract:
An integrated haptic system may include a digital signal processor and an amplifier communicatively coupled to the digital signal processor and integrated with the digital signal processor into the integrated haptic system. The digital signal processor may be configured to receive a force sensor signal indicative of a force applied to a force sensor and generate a haptic playback signal responsive to the force. The amplifier may be configured to amplify the haptic playback signal and drive a vibrational actuator communicatively coupled to the amplifier with the haptic playback signal as amplified by the amplifier.

Publication number: US20220029532A1
Application number: 17/494,424

Abstract:
A bipolar output charge pump circuit having a network of switching paths for selectively connecting an input node and a reference node for connection to an input voltage, a first pair of output nodes, two pairs of flying capacitor nodes, and a controller for controlling the switching of the network of switching paths. The controller is operable to control the network of switching paths when in use with two flying capacitors connected to the two pairs of flying capacitor nodes, to provide a first mode and a second mode when in use with two flying capacitors connected to the flying capacitor nodes, wherein at least the first mode corresponds to a bipolar output voltage of +/−3VV, +/−VV/5 or +/−VV/6.
