    Abstract: A case (100) is provided for housing and charging one or more wireless devices (180), such as wireless earbuds. The case (100) includes capacitive sensing circuitry (120) for detecting whether the wireless devices (180) are positioned inside the case (100) based on a capacitance of the wireless devices (180). The case (100) also includes a transceiver (150) for transmitting data to and receiving data from the wireless devices (180). When the wireless devices (180) are positioned inside the case (100), an electrical component (110) inside the case operatively connects the capacitive sensing circuitry (120) and the transceiver (150) of the case (100) to the wireless devices (180). The case (100) further includes one or more processors (140) for controlling the capacitive sensing circuitry (120), the transceiver (150), and the electrical component (110).

    Abstract: The present disclosure describes a system and method for resetting firmware in an electronic accessory, such as a wearable electronic device, without a physical reset button on the accessory. A secondary device, such as a case for the accessory, can serve as a power source that initiates the reset. The reset may be manually initiated, for example by a user pressing a button, or automatically initiated, such as by the secondary device detecting that the accessory is unresponsive. The secondary device sends a reset command to the electronic accessory through a power line connection. The power line connection may be made, for example, upon contact of the accessory with the secondary device. In some examples, the reset command may be an elevated power level. Upon receiving the reset command through the power line, the accessory completes the reset.

    Abstract: A first device provides both power and data to a second device over a power line connection between the two devices. The first device includes a power line extending from a power supply, a ground line extending from a ground, a first impedance in the power line, and a second impedance in the ground line. A modulator comprised of a transistor and modulator impedance is between the first impedance and the second impedance, and a tank capacitor is between the power line and the ground line, outside the first impedance and second impedance. A comparator is coupled between the first and second impedance. A switch may be included to short out the first and second impedance, thereby enabling transmission of only power for period of time, and return to a mode of transmitting both data and power. The first device may also receive data from the second device over the power line connection.

    Abstract: The subject matter described herein provides systems and techniques for controlling the production of eNoise in an audio playback system. The eNoise may be an audible noise produced when a current, such as a noise/ripple current, flows through a battery of the audio playback system. Such eNoise may be reduced by limiting the current, such as noise/ripple current, flowing through the battery. In some examples, the noise/ripple current may be diverted to the main board of the audio playback system by adding a source of current. A circuit to produce such a current may include transistor(s), capacitor(s), and/or resistor(s). Using the current source and/or such a circuit may also divert the noise/ripple current away from the battery, thereby reducing the eNoise produced.

    Abstract: The present disclosure provides a magnetic system within a case for an electronic accessory. The case may include a housing portion and a lid coupled to the housing portion. Within the housing portion may be a housing magnet. The housing magnet may be oriented such that the magnetic field of the housing magnet is oriented transverse to a longitudinal axis of the case. The housing magnet may have a size and strength to magnetically couple the electronic accessory within a cavity of the housing. A hinge magnet may be located along an axis of rotation of the lid with respect to the housing. The hinge magnet and housing magnet may magnetically interact to form a bistable magnetic hinge. Thus, the one housing magnet may be large enough and have a strong enough magnetic field to perform various functions.

    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.
