    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: Utilizing remote control profile information for configuration of a remote control device. A media processing device may store a remote control profile, locally or on a server accessible via a wide area network, which may include information for configuring a remote control device to utilize one or more wireless remote control commands for controlling the media processing device. The media processing device may also detect one or more wireless remote control commands for controlling one or more other electronic devices and update the remote control profile to include information for configuring a remote control device to utilize those commands. It may be determined to configure a remote control device according to the remote control profile based at least in part on proximity of the remote control device to the media processing device. The remote control device may then be configured according to the remote control profile.
