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: System-in-package modules that can provide a high level of functionality, are space efficient, and are readily manufactured. In an example, a high-functionality system-in-package module can include both a wireless circuit and an antenna. In an example, a space-efficient system-in-package module can include different vertical interconnect paths that can be used to connect the wireless circuit to the antenna. In an example, instead of being shaped as a traditional rectangular cuboid, a space-efficient system-in-package module can have a shape that more closely matches contours of an enclosure for an electronic device.

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: An inductive charging system can include a transmitter device and a receiver device. The transmitter device may be adapted to detect when a receiver coil in the receiver device is coupled to a transmitter coil in the transmitter device. For example, the current input into a DC-to-AC converter in the transmitter device can be measured and coil coupling detected when the current equals or exceeds a threshold value.

Abstract: An alternating current (AC) to direct current (DC) power converter may have a connector with a pair of power supply contacts and a pair of data contacts. An electronic device may be connected to the connector of the power converter. The power converter may supply DC power to the electronic device using the power supply contacts. The power converter may include control circuitry that has a resistor coupled across the data contacts. When the electronic device and the power converter are connected to each other, each may advertise to the other that capabilities are present that exceed industry standards. At the same time, standard-compliant discovery operations may be performed to probe the value of the resistance of the resistor that is coupled across the data contacts. When extended capabilities are discovered, extended functions may be performed including accelerated charging functions and data communications functions.

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. 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: 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.

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.
