Abstract: 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.

Abstract: A level of wear of a stylus tip can be estimated and in accordance with a determination that the level of wear of the stylus tip exceeds a threshold, the stylus input functionality of an electronic device can be disabled. The threshold can be set such that the stylus can be disabled before the stylus sensing performance degrades to a degree perceptible to a human and/or before exposing internal portions of the stylus that can scratch a touch screen. Additionally or alternatively, a notification can be provided to indicate to a user that the stylus tip should be replaced. In some examples, the estimated level of wear can also be used to provide warning notifications. Stylus tip wear can be estimated, for example, based on a detected total signal strength or based on an estimated total distance traversed by the stylus tip across a surface.

Abstract: In some examples, a stylus can include a conductive shield. In some examples, the conductive shield can include a plurality of traces along an edge of a printed circuit board (PCB) including the stylus circuitry. In some examples, the conductive shield can include a shield can coupled to the PCB and disposed around the components of the stylus circuitry. In some examples, the conductive shield can include a hollow portion into which the stylus circuitry can be disposed and a solid portion that can act as a reference electrode. In some examples, the conductive shield can include a hollow sleeve disposed around the stylus circuitry. In some examples, the conductive sleeve can be attached to the PCB. In some examples, the conductive sleeve can be disposed between layers of a housing of the stylus. In some examples, the conductive sleeve can be integrated with the stylus housing.

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: 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.

Abstract: A ring electrode to determine the orientation of the stylus relative to the surface. The stylus can include a ring electrode configuration which can improve capacitive coupling between the ring electrode and the touch panel. The ring electrode configuration can include a ring electrode and ground ring, and ground plate. By varying the lengths of ring electrode, ground ring, ground plate, and the distance between these elements, the electric field emanating from the ring electrode can be tuned to optimize the capacitive coupling between the ring electrode and surface. In some examples, the ring electrode can include multiple sub-rings. In some examples, the ring electrode can comprise a crown shape including projections, each having a width that tapers to a minimum width along the length of the ring electrode.

Abstract: 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.
