Abstract: Methods, systems, and apparatus for determining whether an accessory includes particular circuitry. A host device may measure a first voltage and a second voltage received from an accessory, where the voltages are provide through the accessory from a power source. Before measuring the second voltage, the host device may send an instruction to the accessory instructing the accessory to alter an impedance of the power path between the power source and the host device, and the host device may draw at least a threshold amount of current from the power source via the accessory. The host device may then determine whether the accessory includes particular circuitry based on the relationship between the first voltage and the second voltage.

Abstract: An electronic device may contain an input-output device such as a speaker, vibrator, or near field communications antenna. The input-output device may include an inductor. The inductor in the input-output device may be shared by wireless charging circuitry in the electronic device so that wireless charging signals can be converted into power to charge a battery in the electronic device. A separate inductor may also be provided within an input-output device to support wireless charging. A drive circuit may supply drive signals to the input-output device such as audio signals, vibrator control signals, or near field communications output signals for external near field communications equipment. An input amplifier that is coupled across the inductor in the input-output device may be used in receiving near field communications signals.

Abstract: This is generally directed to adjusting signaling properties based on cable attributes. In some embodiments, the cable attributes can include information such as the length of a cable, the diameter of a cable, the type of plug on a cable, the type of or presence of shielding on a cable, or any combination of the above. This information can then be used to determine the appropriate signaling properties for that cable (e.g., with respect to an EMC standard). The appropriate signaling properties may, for example, optimize the signal that is used to drive the cable while still allowing the cable to generate emissions that are within acceptable EMC standards. In some embodiments, the appropriate signaling properties can include factors such as the drive strength of the signal, the slew rate of the signal, the maximum voltage of the signal, the frequency of the signal, or any combination of the above.

Abstract: An adapter for providing connectivity between a host connector of a host device and an accessory connector of an accessory that is incompatible with the host connector is described. The adapter can include a host interface connector that is compatible with the host connector, and an accessory interface connector that is compatible with the accessory connector of the accessory. The adapter may further include an identification module that can provide adapter identification information to a host device connected to the host interface connector, and may also include an authentication module that can authenticate an accessory connected to the accessory interface connector.

Abstract: An adapter for connecting an accessory to a portable electronic device includes a first connector compatible with a connector of the portable electronic device and a second connector compatible with a connector of the accessory. The connectors of the accessory and the portable electronic device are otherwise incompatible with each other. The adapter provides two levels of authentication. First, the adapter authenticates itself to the portable electronic device. If this first authentication is successful, then the adapter authenticates the accessory to the adapter.

Abstract: Systems and methods are provided for reducing unwanted noise in an electronic audio signal, wherein a computing device having a microphone is configured to receive signals from a sensor on an external device such as a camera, second microphone, or movement sensor. The signals from the sensor are used to identify sound information or characteristics of sounds made by a source of noise, and the audio signal of the microphone is modified to reduce unwanted sounds based on that sound information or based on sounds identified a second audio signal obtained by the second microphone, thereby improving teleconference and video conference audio quality and removing distracting noises from transmitted audio output.

Abstract: A personal audio device (e.g., headphones, earphones) can have an earpiece (e.g., an ear cup or earbud) with a removable cushioning member (e.g., headphone cushions or ear tips for earbuds). The cushioning member can include an identification tag that encodes identification data for the cushioning member. When the cushioning member is attached to the earpiece, the identification tag is brought into proximity with a tag sensor in the earpiece and the earpiece can read the identification tag to determine identification data for the cushioning member. The identification data can be used to modify a behavior of the earpiece and/or of a host device communicably coupled to the earpiece.

Abstract: Methods, systems, and apparatus for enabling a power path between a power source and a host device via an accessory. A host device may send, to an accessory arranged within the power path, via a first data pin arranged in the host device, a request for an accessory identifier. The accessory identifier identifies the accessory. The host device may then determine whether the accessory identifier is received from the accessory within a specified period of time or whether a received accessory identifier is valid. If the accessory identifier is not received from the accessory within the specified period of time, or a received accessory identifier is not valid, the host device sends a new request for the accessory identifier to the accessory via a second data pin different than the first data pin.
