An electronic device includes a housing coupled to a display window, a battery and a plurality of inductive charging transmit coils coupled to the battery. The plurality of inductive charging coils are positioned within the enclosure to generate an inductive charging region that extends through the display window and across at least a portion of an exterior of the display window. Sensing circuitry is configured to sense a position of a stylus at the display window and a processor is configured to selectively engage and disengage one or more of the plurality of inductive charging transmit coils based on the sensed position of the stylus. The stylus receives power when it is positioned within the inductive charging window.

Electronic device having an inductive charging system

A wireless power transmission system may include a wireless power transmitting device such as a tablet computer and a wireless power receiving device such as a computer stylus. A wireless power transmitting capacitor electrode may be formed in the tablet computer. A wireless power receiving capacitor electrode may be formed in the computer stylus. The transmitting capacitor electrode may be driven by a drive signal having a frequency of 900 MHz or greater to produce wireless power. The wireless power may be transmitted from the transmitting capacitor electrode to the receiving capacitor electrode on the stylus via near field capacitive coupling. The transmitting and receiving capacitor electrodes may each include conductive traces on dielectric substrates. The conductive traces may follow meandering paths to maximize the possible capacitive coupling efficiency between the capacitor electrodes and thus the end-to-end charging efficiency of the wireless power transmission system.

Capacitive wireless charging systems

Embodiments describe a receiving element that includes a ferromagnetic structure axially symmetrical around a central axis disposed along a length of the ferromagnetic structure. The ferromagnetic structure includes a groove region defining two end regions on opposing sides of the groove region, where the groove region has a smaller length than the two end regions. The receiving element also includes an inductor coil wound about the groove region of the ferromagnetic structure and in between the two end regions.

Attachment devices for inductive interconnection systems

Disclosed are structures, devices, methods and systems for providing dynamically variable internal illumination to individual input devices of an electronic device, such as keys of a keyboard. In some embodiments, input devices contain multiple LEDs whose light intensity may be varied to alter a tone or a color of light used for the internal illumination a key. The LEDs may be micro LEDs and may be internal components of the input device as a unit. In some embodiments, the LEDs are white light LEDs having different phosphor thicknesses. In some embodiments the LEDs may be RGB LEDs, with individual control of color contributions to modify the internal illumination. Systems incorporating such input devices may need only a reduced set of LED control units. Systems can include a processing unit and a light sensor or camera to detect ambient lighting and adjust internal illumination of an input device accordingly.

An item may have regions that are illuminated by light from a light source. The light source may be based on components such as light-emitting diodes. Diffusing material, luminescent material, and other light-adjusting materials may be incorporate into the item. The item may include movable structures such as movable keyboard key members. Light-emitting diodes may be mounted on a substrate. The substrate may be coupled to keyboard key members, additional substrates, or other structures in an item. The item may include a layer of fabric and layers of other material. Openings in the layers of material may be configured to receive light-emitting diodes. Opaque layers of material may have patterned openings that help define shapes for the illuminated regions.

Illumination systems with light-emitting diodes

Disclosed herein is an input device having variable make points. More specifically, the various embodiments described herein are directed to an input device having a key, a first button member and a second button member. A dielectric may be positioned between the first button member and the second button member. The key is also associated with a capacitive sensor that is configured to determine a change in capacitance as a distance between the first button member and the second button member changes.

An electronic device may be provided with wireless circuitry that includes a radio-frequency transceiver circuit and an antenna. The antenna may be a patch antenna formed from a patch antenna resonating element and an antenna ground. The patch antenna resonating element may be formed from a metal patch on a printed circuit board. The antenna ground may be formed from a metal housing having a planar rear wall that lies in a plane parallel to the metal patch. The radio-frequency transceiver circuit may be coupled to the metal patch through traces on the printed circuit and may be coupled to rear wall of the housing through a screw and a screw boss in the housing. Buttons and other electrical components may be mounted on the printed circuit board and may be coupled to control circuitry on the printed circuit board through the metal patch.

The disclosed embodiments provide a system that facilitates the use of an electronic device. The electronic device may be a keyboard, a mouse, a trackpad, a remote control, a mobile phone, a wireless phone, a toy, a portable media player, a game controller, and/or a camera. During operation, the system monitors a state-of-charge of a battery used to power the electronic device. Next, the system calculates a charge threshold associated with a low-battery warning for the battery based on the monitored state-of-charge. If the state-of-charge of the battery reaches the charge threshold, the system generates the low-battery warning.
