An IO interface for configuring hard IP embedded in a FPGA includes a register load signal, a CSR initialization signal, and a register data signal. The multi-layer semiconductor structure includes an insulator-filled deep trench isolation structure that is formed through an active silicon layer, a first insulator layer, and a first bulk layer and extends to a second insulator layer. The method includes physical parameters like target programme and interferer programme which combined with the scenarios: information gathering, entertainment and reading andor working, constitutes modes of operations that may be processed and controlled by a system controller. A glint free image may also be determined. Compliance chambers and throttle valves associated with each of the sample holders regulate the pressure gradient and back pressure across the prosthetic devices being tested. A secondary pickup is constructed and arranged to mate with the ignition coil and to receive the secondary voltage signals.
