A technique or mechanism for use with a vibrator to be employed for subterranean surveying includes receiving, from a sensor, a unipolar indication of movement of an actuator mass of the vibrator. The protection circuit detects the main current flowing through the power switching element by detecting a voltage between predetermined two points of the metal electrode. A transmitter component is configured for receiving the combined signal and generating one or more data streams based on the combined signal. The substrate handling module has a loader assembly, a flipper assembly, and a factory interface. For example, in an embodiment, an OS or VMM Independent architecture involves creating one or more containers on a processor by dynamically partitioning resources between the HOST OSVMM and the OI container.
