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.

Abstract: Systems and methods for wireless power transfer to an electronic device. In some embodiments, the disclosed devices includes one or more arrays of transmit coils within a charging surface on which an electronic device is placed for charging. A controller may apply a first alternating signal with a first phase to a first transmit coil, and a second alternating signal with a second phase to a second transmit coil. The offset of phases may produce increased magnetic flux through a receive coil of the electronic device to transfer power more efficiently.
