A torque sensor can be configured to detect the positions of rotor targets relative to the position of respective receiver structures. A torque sensor can include an oscillator circuit coupled to an excitation coil. The oscillator circuit can be configured to generate a periodic voltage signal and energize the excitation coil with the periodic voltage signal. The inductive torque sensor can include a stator circuit board including receivers with receiver structures that are periodically repeated. The inductive torque sensor can include rotor targets coupled to respective rotors, the rotor targets can be configured to affect the strength of the inductive coupling between the excitation coil and the respective receivers. The inductive torque sensor can include processing circuitry configured to provide signals associated with positions of the rotor targets relative to their respective receiver structures.

A wearable device can include a wearable band configured to contact a user of the wearable device, an actuator, a sensor, and one or more processors in communication with the actuator and the sensor. The processors can be configured to measure a back electromotive force (“EMF”) of the actuator; determine, based on the measured back EMF, data that describes a contact force between the wearable band and the user; and determine, based on the data that describes the contact force, a quality metric describing a data quality of sensor data collected by the sensor. In some embodiments, the processor(s) can determine, generate sensor output data based on the sensor data and based at least in part on the data describing the contact force between the wearable band and the user. For example, one or more machine-learned models maybe leveraged to generate sensor output data that is compensated for the wearable band being too tight or too loose.

A handle assembly for a closure of a vehicle includes a force-based sensor disposed beneath an uninterrupted class-A surface and responsive to a force applied thereto. The handle assembly includes a handle ECU, configured to monitor the force-based sensor and to communicate with an electronic latch controller. A super-capacitor is disposed on a PCB within the handle assembly for providing electrical power to the handle ECU and the force-based sensor. The handle ECU includes one or more feedback devices such as LED lights, acoustic, and haptic devices to provide information about the status of the closure and the electronic latch system. The handle assembly is also configured to provide different responses to two or more different levels of force applied to the force-based sensor. An output interface in the handle assembly provides wired and wireless backup communications to the electronic latch controller.

A robotic arm comprising an operation end, a base, a sensor unit and a control unit is provided. The operation end is connected to the base, and the operation end is configured to reach an operational area. The sensor unit provides a sensor signal according to the force applied by or the motion of an operator. When the operation end reaches the operational area, the control unit sets a fixed position on the robotic arm between the base and the operation end. When the sensor signal from the operator fulfills a default condition, the control unit moves the robotic arm away from the operator, without moving the fixed position on the robotic arm.
