A thin film transistor may include an active layer formed on an insulating substrate and formed with sourcedrain regions and a channel region; a gate insulating film formed on the active layer; and a gate electrode formed on the gate insulating film. The signal contacts are arranged to come into contact with signal terminals of the FFC. In other embodiments a method of forming a roadway comprising cured asphalt composite is provided. To normalize the sensor output values across regions, gain and offset information can be obtained in advance, stored in nonvolatile memory, and later used to normalize the sensor output values so that all regions in the sensor panel can trigger virtual buttons similarly, providing a uniform \u201cresponse function\u201d at any location on the sensor panel. Based upon the verified class, the transmission of the request is controlled.
