An inflatable doll display has a barrel and a doll. In particular, the present invention relates to providing access to a large amount of data while consuming a relatively small amount of a critical resource. The contact members are configured to movably engage corresponding pins of the IC upon respective movement of the apertures so as to provide electrical and mechanical contact thereto. With the present invention, a conventional feedback circuit, an adder and the like become unnecessary by outputting the PWM which originally contains no offset voltage. In accordance with the available data for a specific customer, a corresponding rule set is examined in the discount table and is employed for an operation. The method includes: lithographically forming a plasmonic nanostructure on a substrate; encapsulating the plasmonic nano structure in high temperature resistant material; annealing the plasmonic nanostructure; and removing the high temperature resistant material to reveal the annealed plasmonic nano structure.
