Abstract:
A combination touch and transducer input system is provided, which facilitates user input into an electronic system with a finger and/or a transducer (e.g., a stylus). The system includes a transducer configured to generate an electric field, and a sensor including an array of electrodes and a controller. The transducer is configured to transmit digital data, such as pen pressure data and switch status data, to the sensor. For example, the transducer comprises electronic circuitry configured to encode the digital data in a signal for transmission to the sensor. The sensor controller is configured to operate both in a touch sensing mode and in a transducer sensing mode. During the touch sensing mode, the controller determines a position of a proximate object (e.g., a finger) by capacitively sensing the object with the array of electrodes. During the transducer sensing mode, the controller determines a position of the transducer based on a signal received by the array of electrodes from the transducer, and also receives and decodes the digital data encoded in the received signal. Digital data can be encoded in a signal using any suitable digital modulation techniques, such as a Frequency-Shift Keying (FSK) technique.

Claim (Index 9):
A method of bi-directional communication between a pen-shaped stylus and a sensor controller coupled with sensing electrodes, the method comprising:\n establishing a wireless link between the pen-shaped stylus and the sensor controller, wherein the pen-shaped stylus is operable to generate an electric field for signal transmission to the sensor, and the signal transmission includes transmission of a pressure signal indicative of a pen pressure applied to a tip of the pen-shaped stylus; controlling the sensor controller to transmit, over the wireless link to the pen-shaped stylus, information that configures the pen-shaped stylus to start the signal transmission from the pen-shaped stylus; controlling the sensing electrodes to detect the electric field generated by the pen-shaped stylus; calculating a position indicated by the pen-shaped stylus based on the electric field generated by the pen-shaped stylus and detected through the sensing electrodes; and controlling the sensor controller to receive the pressure signal transmitted from the pen-shaped stylus, wherein the information that configures the pen-shaped stylus to start the signal transmission from the pen-shaped stylus is encoded with digital data, and the signal transmission is started in response to the pen-shaped stylus receiving and decoding the digital data, and wherein the pressure signal transmitted from the pen-shaped stylus is digitally encoded.
