A process for a monitor working in a DPMS mode applies when a monitor ends a working mode and enters the DPMS mode. In estimating an object boundary the active contour deforms from an initial shape to adjust to image features using an energy minimizing function. In some embodiments, the transport links may transfer the testing frames while the transport links are transporting other data traffic. The wheels are mounted on the lower surface of the bottom board. Through introduction of the adhesive via the central opening enables a flow to the outside, without interference from the metering needles, when the DVD halves rotate. The interface module can be integrated into the motor or can be fitted to the latter.
