Abstract
A method of one embodiment includes generating, by a stylus, a composite signal. The composite signal includes a first signal having a first frequency, the first signal being used by a touch-sensing device to determine a position of the stylus relative to the touch-sensing device, and a second signal having a second frequency. The second signal may include status information such as an amount of force exerted on the stylus, battery information, orientation information, information indicating whether the stylus is within a threshold distance of the touch-sensing device, information indicating a status of a button of the stylus, and/or information indicating input from a user of the stylus. Furthermore, the second frequency is higher than the first frequency. The stylus sends the composite signal to the touch-sensing device, and an electrode array of the touch-sensing device may receive the composite signal. The touch-sensing device may determine a position of the stylus by processing the composite signal and may also determine the status information by processing the composite signal.
