A modular cable protector has a side ramp extending laterally outward and downward from the top to the base along one side of the cable protector, and a side ramp cover extending laterally outward and upward from the base to the top along the opposing side of the cable protector. The use of a deep n-well lessens the parasitic capacitance by placing a diode in series with the interlayer dielectric cap. The access key and the smart card ID are stored in the client computer’s CMOS or non-volatile memory for boot-up access. The first position is in a direction in which the movable unit would move according to the force of gravity, after the anti-shake operation is finished. Each hole opens onto two lateral faces of the element in relief, and the holes are situated on one and the same side of the mean plane of the incision in spaced relationship to the incision.
