A method and system are implemented to instantaneously detect a hot plugging of a video connector in a computer device by detecting a change in the electrical state of one ground pin of the video connector. The stationary blade is positioned adjacent to at least one of moving-blade disks in an axial direction of the gas turbine. Each partial-scan samples a fraction of the imaging volume. A cutting register error is determined from the registration information and the position of the knife cylinder is influenced to correct the determined cutting register error. When the main switches are turned off and the return switches are turned on, the capacitors charge in parallel. The micro device has a cantilever structure in which one end of support means is made a fixed one fixed to the substrate and the other end to which an active element is provided is made a free end.
