Claim Text:
1. A sensor controller to control operation of a sensor, wherein the sensor includes an array of electrodes arranged to define a sensor surface, the array of electrodes including first electrodes disposed along a first direction and second electrodes disposed along a second direction different from the first direction; and wherein the sensor is configured for use with a pen-shaped transducer, the pen-shaped transducer being capable of generating an electric field which is used by the sensor to detect a position indicated by the pen-shaped transducer on the sensor surface, the pen-shaped transducer including one or more of: i) a pressure sensor configured to detect pressure applied to a tip of the pen-shaped transducer, the pressure sensor being used to generate a pressure signal indicative of a detected pressure value, ii) a user-operable switch used to switch operational states of the pen-shaped transducer, the switch being used to generate a switch signal indicative of an operational state of the switch, and iii) an ID signal indicative of an ID of the pen-shaped transducer; the sensor controller comprising:
