An input device for an electronic device includes an enclosure and a top member defining an input surface having multiple differentiated input regions. The input device further includes a first force sensing system associated with a first area of the top member and including a first group of the differentiated input regions, and a second force sensing system associated with a second area of the top member and including a second group of the differentiated input regions. The input device further includes a touch sensing system configured to determine which input region from the first group of the differentiated input regions corresponds to the first force input and to determine which input region from the second group of the differentiated input regions corresponds to the second force input.

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.

Embodiments are directed to a user input device and methods related to the use thereto. In one aspect, an embodiment includes a flexible fabric attachable to a user having a first portion and a second portion. The first portion may be moveable in relation to the second portion. The embodiment may further include a controller configured to identify an input configuration based on a position of the first portion relative to a position of the second portion within a three-dimensional space. The embodiment may further include a haptic feedback structure disposed adjacent the flexible fabric and configured to provide haptic feedback based on the input configuration.

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.

Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.

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.
