A micro-electromechanical switch includes a substrate, stationary actuator comb teeth extending from a stationary actuator pad supported above the substrate, stationary contact comb teeth extending from a stationary contact pad supported above the substrate, and a body suspended over the substrate for rotation about an axis perpendicular to the substrate. The MAG node comprises a server for providing configuration information. A tongue-shaped end portion extends from the end opposite the concave end for securing the hand surgery table to a conventional operating table where the patient may lie and rest his or her forearm on the hand surgery table top. The hemostatic valve is configured to prevent blood in the blood vessel from exiting the introducer sheath assembly when the elongated sheath is located in the blood vessel. As viewed from above, the laser diode does not overlap the two reproduction wiring layers but overlaps at least one of the two recording wiring layers.
