The sensor controller supplies a determined AC signal to one or more AC signal transmission electrodes that form part of a plurality of sensor electrodes included in the sensor electrode group, and the sensor controller transmits, from cancellation signal transmission electrode(s) different from the AC signal transmission electrodes, a cancellation signal configured to prevent a signal transmitted from the AC signal transmission electrodes from appearing in a ground terminal of a detection circuit of the stylus. The sensor controller thusly configured may facilitate preventing a situation in which the stylus cannot detect an uplink signal and facilitate preventing the uplink signal from affecting the operation of another apparatus such as a display apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor controller","description":"A sensor controller is provided, to be connected to a sensor electrode group configuring a surface.
