A doubly-anchored thermal actuator for a micro-electromechanical device such as a liquid drop emitter or a fluid control microvalve is disclosed. Furthermore, the base band unit has a function of calculating the throughput of radio communications on the basis of a bit error rate and computing reception sensitivity on the basis of a signal-to-noise ratio. Plating of the conductive material can place prior to, during and after usage of the workpiece-surface-influencing device, particularly after the workpiece surface influencing device no longer contacts any portion of the top surface of the workpiece, to achieve desirable semiconductor structures. The adjustment screws are disposed so as to be coaxial with respect to each of the elastic members and are mounted to at least one of the mount unit and the imaging element unit. In some embodiments the validation process can occur in a single user communication session, or otherwise in a near real-time process.
