    Abstract: A removable case may receive an electronic device. A male connector in the case may mate with a female connector in the device. A battery in the case may supply power to the device through the male connector. The electronic device may have an antenna. The case may have a supplemental antenna that compensates for variations in performance in the antenna when the device is received within the case. The supplemental antenna may be a parasitic antenna resonating element that is formed from metal traces on a flexible printed circuit. The flexible printed circuit, a metal trim structure, and a plastic support structure may form portions of a connector support structure in the case.

    Abstract: Apparatus and methods for digital bus operation. In one embodiment, the digital bus is a bidirectional, time-division multiplexing (TDM) audio bus operation, and a bus technology is described that enables multi-drop (e.g., multiple device, multiple node, etc.) connectivity for real-time audio over a small form factor interface (e.g., as few as two (2) wires). Specifically, an exemplary tri-level signaling scheme provides bidirectional functionality, real-time clock edges, audio data, in a multi-drop topology in one implementation.

    Abstract: A charging case for a pair of earbuds that comprises: a body having one or more cavities configured to receive the pair of earbuds; a lid attached to the body and operable between a closed position where the lid is aligned over the one or more cavities covering the pair earbuds and an open position that allows a user to remove the pair of earbuds from the body; one or more sensors that generates sensor data; a controller coupled to receive the sensor data from the sensor and operable to detect when the charging case is in freefall and/or suffers an impact event based, at least in part, on the sensor data and generate a trigger signal in response to detecting the impact event; and an earbud protection mechanism responsive to the trigger signal and operable to retain the pair of earbuds within the charging case.

    Abstract: Simplified interfaces for charging and communication between accessories and docking stations. One example may provide an interface for charging and communication between an accessory and docking station where data and a charging voltage are provided over the same pins. An accessory may determine that it is in a powered docking station by receiving a charging voltage. The accessory may determine that it is in an unpowered docking station by providing a voltage to the unpowered docking station, where the unpowered docking station uses the voltage to power an oscillator. The oscillator signal may be received by the accessory, which may use the presence of the signal to determine that it is in an unpowered docking station.

    Abstract: An electronic system can include a charged system and a charging system. The charged system can include a charger and a battery configured to be charged thereby. The charger may be configured to receive power from a charging system that includes a power converter configured to supply power to the charger and a controller configured to control the power converter. The controller may be configured to receive feedback information from the charged system, including one or more voltages. The controller may be further configured to determine an output voltage compensation value for the power converter as a function of the feedback information and to set an output voltage of the power converter as a function of the compensation value. The compensation value and output voltage may be selected to maintain a preselected headroom between a battery charging target voltage of the charger and a voltage supplied to the charger.
