Abstract: Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described. Upon detecting an input power signal from the charging source, an accessory may send an identification request to the host device and authenticate the host device based on the identification information received from the host device. Upon authenticating the host device, the accessory may enable a power path between the charging source and the host device to supply a charging current to charge the host device.

Abstract: A case for a pair of earbuds includes a housing having cavities to receive the pair of earbuds and charging circuitry that is configured to initiate charging of the pair of earbuds when an earbud detector detects that the earbuds are inserted within the cavities.

Abstract: A case for a portable listening device includes a lid and a lid sensor to detect if the lid is in an open or a closed position. The case further includes circuitry configured to turn on a wireless radio within the portable listening device when the lid sensor detects the lid is moved from the closed position to the open position.

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: Power transfer systems including a direct current source and a plurality of outputs operable in several modes. A ground mode may couple an output to circuit ground and a current mode may couple the output to the direct current source. The power transfer system may also include a controller configured to iteratively select a pair of outputs from the plurality of outputs. Once a pair is selected, the controller may set a first output of the pair of outputs to the current mode and the second to ground mode for a determined duration. After the duration has passed, the controller may set the first output to the ground mode and the second output to the current mode for the same duration. Thereafter the controller may select another pair of outputs.

Abstract: A case for a pair of wireless earbuds includes a lid and a lid sensor configured to generate a detect signal when the lid is moved from a closed position to an open position. The case further includes circuitry configured to, in response to receiving the detect signal, send a signal to the wireless earbuds to turn them on and to initiate a pairing sequence between the wireless earbuds and an electronic device.

Abstract: The wireless earphone (1) comprises a housing (2) having a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet (5) at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver (6) is inside the bud portion. Electronic circuitry (7,24) inside the housing (2) includes a wireless communications interface (4) to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery (3) as a power source for the electronic circuitry is located inside a cavity of the stem portion.

Abstract: An adapter for enabling connection of a portable electronic device with an accessory includes two connectors, an identification device, a power control device, and power clamping circuitry. All of these components may be included in a single integrated housing. Another adapter may have a cable with two connectors connected to either end of the cable. One of the connectors may house the identification device and the power control device. Optionally, the adapter may also house the power clamp circuitry.
