A device can include a wireless power transfer coil configured to be magnetically coupled to a wireless power transfer coil of a complementary device, wireless power transfer circuitry, a processing and communications system, and a wireless communications coil coupled to the processing and communications system, the communications coil comprising one or more windings configured to be magnetically coupled to a vertical communications coil of the complementary device to allow communications between the processing and communications system and the complementary device, wherein the one or more windings of the communications coil are disposed in at least one plane parallel to the plane of the vertical communications coil.

Magnetics configurations for wireless power transfer and communications in electronic device

A magnetic alignment assembly can be incorporated into an electronic device to facilitate alignment with another device. The magnetic alignment assembly can include a main magnet (e.g., a square or rectangular magnet) having a magnetic dipole in an axial direction and a ring magnet coaxial with the main magnet. The ring magnet can be smaller than the main magnet. The ring magnet can be positioned between the main magnet and an interface surface.

Housing for an electronic device

A blood pressure measurement device may include one or more piezoelectric sensors (e.g., differential piezoelectric sensors) for detecting blood flow through a limb of a user as part of determining blood pressure measurements. The piezoelectric sensor(s) may additionally or alternatively be used to determine one or more biological parameters of users (e.g., a ballistocardiogram, a heart rate, a heart rate variability, and a pulse wave velocity). The blood pressure measurement device may additionally or alternatively include a capacitive sensor for determining a pressure applied to the limb of the user by the blood pressure measurement device and/or operational states of the blood pressure measurement devices (off-arm, on-arm, inflating, deflating, tightness, and the like).

Blood pressure measurement using device with piezoelectric sensor

A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

Charging case for wireless earphones

This application relates to a wireless charger with increased efficiency during operation. The wireless charging assembly includes a wireless charger and an electronic device. A transmitter coil in the wireless charger can induct magnetic flux to a receiver coil in the electronic device via a magnetic flux pathway.

Wireless magnetic charger with solenoids

An electronic device such as a wristwatch may have a housing with metal portions such as metal sidewalls. The housing may form an antenna ground for an antenna. An antenna resonating element for the antenna may be formed from a stack of capacitively coupled component layers such as a display layer, touch sensor layer, and near-field communications antenna layer at a front face of the device. An additional antenna may be formed from a peripheral resonating element that runs along a peripheral edge of the device and the antenna ground. A rear face antenna may be formed using a wireless power receiving coil as a radio-frequency antenna resonating element or may be formed from metal antenna traces on a plastic support for light-based components.

Inductively chargeable earbud case

Embodiments disclosed herein describe a wireless power receiving system for an electronic device includes: a first inductor coil configured to receive power primarily at a first frequency and from magnetic fields propagating in a first direction; and a second inductor coil configured to receive power primarily at a second frequency and from magnetic fields propagating in a second direction, wherein the first frequency is different than the second frequency.

Architecture of portable electronic devices with wireless charging receiver systems

An inductor coil includes a wire which is wound in alternating layers such that the surface area of the wire in each winding viewed from above or below the coil is substantially equal in each half of the coil defined by a line bisecting the center point in each layer. The layers are also wound in a serpentine fashion to balance the capacitance between layers. The substantially equal surface area of wire in each half of a coil layer and in adjacent coil layers results in a balanced capacitance of the coil which, in turn, results in reduced common mode noise.

Antenna integration for portable electronic devices having wireless charging receiver systems

In some embodiments, an electronic device includes an electronic component that is at least partially encapsulated by an adhesive doped with soft magnetic material that functions as an EMI shield for the electronic component. In various embodiments, an electronic device includes a first magnetic component separated from a second magnetic component by a gap within which is positioned an adhesive doped with soft magnetic material. The doped adhesive is positioned in a magnetic path between the first and second magnetic components and aids in magnetically coupling the first and second magnetic components and/or guides magnetic flux between the first and second magnetic components.

Magnetically doped adhesive for enhancing magnetic coupling

Electronic devices are disclosed that include a housing and a display coupled to the housing by an adhesive. The display includes an antenna component. The device includes a casing coupled to the display, a circuit board positioned within the housing, a wireless communication component coupled to the circuit board. The device includes a receptacle connector coupled to the housing and an electrical contact electrically coupled to the wireless communication component. The device further includes a plug connector that electrically connects the antenna component to the wireless communication component. The plug connector includes a first portion electrically coupled to the antenna component, positioned within the casing and translatable within the casing along a first axis orthogonal to a longitudinal axis of the first portion. The plug connector includes a second portion electrically coupled to the first portion, extending into the receptacle connector and contacting the electrical contact of the receptacle connector.
