Abstract
An active stylus includes a body, an electrical connector operatively coupled to the body, wired connection circuitry contained within the body and electrically coupled to the electrical connector, and electrostatic circuitry contained within the body and electrically coupled to the electrical connector. The electrical connector is configured to electrically couple the active stylus with a device via a wired connection. The wired connection circuitry is configured to hold at least a portion of the electrical connector at ground when the active stylus is operating in a wired connection mode. The electrostatic circuitry is configured to transmit, via the electrical connector, one or more excitation waveforms when the active stylus is operating in an electrostatic mode.
