Dielectric elastomer or electroactive polymer film transducers configured to minimize high electrical field gradients that can lead to partial discharge and corona. The device then converts the vector-based impedance measurements into near-field individual electrode-based impedance values. An instruction of a second type causes a combination of functional units to respond in the same instruction execution cycle, a result from one functional unit being used by another as part of the execution of the same instruction. A curved guide means is disposed in communication with the side guards for guiding movement of the side guards. The collector includes a first mirror shell positioned inside a second mirror shell that has a chamfered end. The embodiment also may facilitate noise prediction when heavy correlated noise is present.
