Abstract: A circuit for controlling an interface between an integrated circuit of an electronic device and an external device includes each of an interface control switch and an overvoltage protection switch. The interface control switch includes a controller for controlling a mode of the interface between a data communication mode that connects the external device to the integrated circuit of the electronic device via one or more communication lines of the electronic device, and a power transmission mode that connects a power source of the external device to a battery of the electronic device. The controller includes a reset line for resetting the interface control switch. The overvoltage protection switch is connected between the one or more communication ports and the reset line, and is configured to activate the reset line of the controller in response to an overvoltage condition at the one or more communication lines of the electronic device.

Abstract: The present disclosure provides for an arrangement of components within a hearable device, such as earbuds, to reduce H field coupling for E noise improvement. A battery is positioned above a magnet and speaker, such that the battery is not coaxially aligned with either the magnet or the speaker. An internal positive tab of a battery is positioned farthest from a speaker yoke, while an internal negative tab of the battery is closer to the speaker yoke. Magnetic flux poles of a contact magnet have different contributions for electric field coupling.

Abstract: A short circuit protection circuit may comprise a first configuration channel line extending from a first connector, a first resistor connected to the first configuration channel line; a voltage divider connected to a junction point on the first configuration channel line, the voltage divider comprising a second resistor and a thermistor, and a field effect transistor (FET) comprising a source, gate, and drain. The thermistor may be connected to a ground line. The drain of the FET may be connected to the first resistor, the source of the FET may be connected to the ground line, and the gate of the FET may be connected to a second junction point between the second resistor and thermistor of the voltage divider.

Abstract: The present disclosure describes a system and method for protecting an electronic device from high voltages that may exceed tolerance limits for circuitry within the electronic device. A protection circuit blocks high voltages from the device components through gating techniques. Such gating techniques may similarly be used to control whether power is received by the electronic components when an error condition is detected by a control unit.

Abstract: A wireless accessory has one or more sensors positioned at an outer periphery of its housing, thereby forming a knob-like input. The sensors may be configured to detect a change in contact force or contact location of first and second fingertips at respective first and second opposite sides of the periphery. An input gesture is determined based on the detected change, and a command corresponding to the gesture may be executed.

Abstract: The technology provides for an extension member configured to direct a magnetic field from a magnet to a Hall Effect sensor to facilitate detection of magnetic field. By varying the dimensions of the extension member, which may be any arbitrary shape, the relative positions of the magnet and the Hall Effect sensor may be less constrained by the reach of the magnetic field of the magnet, thereby allowing more design possibilities. The extension member may be used in a case, where the extension member may facilitate detection of whether the case is open or closed, the extension member may further provide magnetic attraction to keep the case closed.

Abstract: The technology provides a device, such as a wireless earbud, with capacitive sensing capabilities. For instance, the device may include a housing, and a conductive support positioned inside the housing. The device may further include one or more processors configured to measure a combined capacitance of a plurality of electrodes at the conductive support. Based on the combined capacitance, the one or more processors may detect that the conductive support is inserted into an ear. The one or more processors may then operate the device in a first mode based on detecting that the conductive support is inserted into an ear.

Abstract: This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

Abstract: In some implementations, a wireless charger includes a power transmission coil, a magnet sensor, an electromagnet, and control circuitry. The power transmission coil can wirelessly provide power at a charging area of the wireless charger through inductive coupling. The magnet sensor is arranged to detect the presence of a magnet at the charging area. The electromagnet can generate a magnetic field in the charging area when the electromagnet is energized. The control circuitry is able to selectively energize the electromagnet based on signals generated using the magnet sensor.
