A sensing pixel structure for generating a sensed image with uniform resolution is applied in a light sensor. The image detection circuit generates a compression mode control signal according to a first frame. The printer receives response data from the computer system indicating an association of the one or more selected objects with the one or more selected commands and prints an amended version of the second form including a representation of the selected one or more objects. Through a geographic information system database, the position data is converted to street address data. In an alternate embodiment, the base conduct support integrally forms the dielectric barrier layer via conversion of surfaces of the base conductor using electrochemical, thermal or chemical means to form the dielectric barrier layer.
