摘要： 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.

摘要： 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.

摘要： 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.

摘要： Input device power consumption can be reduced with a magnetic drive system. In some examples, the input device can include a transformer configured to generate a desired high output voltage from logic-level input pulses. In some examples, the distributed capacitance and associated resonance of the transformer can act as a low-pass filter, and can create a relatively clean output waveform from input logic signal waveforms. In some examples, the transformer can be an autotransformer. In some examples, to stabilize an amplitude of the output by sampling the output of the transformer and adjusting the input to the transformer based on the sampled output.

摘要： An electrode for an input device can be designed to reduce wobble over a range of input device orientations. The electrode can include a spherical portion and a tapered portion. In some examples, the electrode can linearly taper away from the spherical portion. In other examples, the electrode can non-linearly taper away forming an elliptical flare. Additionally or alternatively, the electrode can include a spring-loaded member that can couple the electrode to other circuitry of the input device. Additionally or alternatively, the electrode can include a neck portion coupled to the tapered portion, and part of the neck portion can be shielded. The input device can include a first non-conductive material disposed on part of the spherical portion of the electrode and a second non-conductive material disposed between part of the electrode and the first non-conductive material.

摘要： 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.
