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: A dual orientation connector having a connector tab with first and second major opposing sides and a plurality of electrical contacts carried by the connector tab. The plurality of contacts includes a first set of external contacts formed at the first major side and a second set of external contacts formed at the second major side. Each individual contact in the first plurality of contacts is electrically connected within the tab or body to a corresponding contact in the second plurality of contacts. In some embodiments contacts in the first and second pluralities of contacts that are directly opposite each other are coupled together. In some other embodiments, contacts in the first and second pluralities of contacts that are in a cater cornered relationship with each other are coupled together. The first plurality of contacts are symmetrically spaced with the second plurality of contacts and the connector tab is shaped to have 180 degree symmetry so that it can be inserted and operatively coupled to a corresponding receptacle connector in either of two insertion orientations.

Abstract: A system that detects electrical disconnection of one connector from another connector includes a detection circuitry and a protection circuitry. The detection circuitry detects that a plug connector has been electrically disconnected from a corresponding receptacle connector. In response to the detection, the detection circuitry sends a signal to the protection circuitry. In response to the signal, the protection circuitry lowers or terminates power being supplied to a host device via one of the contacts of the plug connector. This helps to prevent shocks/shorts that may be caused by accidental disconnection of the plug connector.

Abstract: Systems and methods for configuring contacts of a first connector includes detecting mating of a second connector with the first connector and in response to the detection, sending a command over one of the contacts and waiting for a response to the command. If a valid response to the command is received, the system determines the orientation of the second connector. The response also includes configuration information for contacts in the second connector. The system then configures some of the other contacts of the first connector based on the determined orientation and configuration information of the contacts of the second connector.

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: 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: Methods and systems for improved efficiency when an inductive power transmitter associated with an inductive power transfer system experiences a low-load or no-load condition. More particularly, methods and systems for detecting when an inductive power receiver is absent or poorly connected to an inductive power transmitter. The inductive power transmitter includes, in one example, a current peak monitor coupled to an inductive power transmit coil. The current peak monitor waits for a current peak resulting from spatial displacement of a magnetic field source within the inductive power receiver, indicating to the inductive power transmitter that the inductive power receiver is moving, or has moved, toward the inductive power transmitter. Other examples include one or more Hall effect sensors within the inductive power transmitter to monitor for the magnetic field source of the inductive power receiver.
