Since the lower portion of the lightning arrestors are connected to the monitor, the length of the connection lines is made sufficiently short.
50 Thermal arched beam microelectromechanical valve US232939 1999-01-19 US06114794A 2000-09-05 Vijayakumar R. Dhuler; Robert L. Wood; Ramaswamy Mahadevan
A MEMS actuator is provided that produces significant forces and displacements while consuming a reasonable amount of power. The MEMS actuator includes a microelectronic substrate, spaced apart supports on the substrate and a metallic arched beam extending between the spaced apart supports. The MEMS actuator also includes a heater for heating the arched beam to cause further arching of the beam. In order to effectively transfer heat from the heater to the metallic arched beam, the metallic arched beam extends over and is spaced, albeit slightly, from the heater. As such, the MEMS actuator effectively converts the heat generated by the heater into mechanical motion of the metallic arched beam. A family of other MEMS devices, such as relays, switching arrays and valves, are also provided that include one or more MEMS actuators in order to take advantage of its efficient operating characteristics. In addition, a method of fabricating a MEMS actuator is further provided.
51 Micro-electromechanical relays US693800 1996-08-01 US6094116A 2000-07-25 Yu-Chong Tai; John A. Wright
A micro-electromechanical relay ("micro-relay") designed to both miniaturize and improve upon present day electromechanical relays. The micromachining fabrication process used to make the micro-relay is based upon technology originally used by integrated circuit (IC) manufacturers. In simplest terms, the preferred process consist of three steps, all performed using micromachining techniques. First, a layer of magnetic material is laid down on a substrate and patterned into a desired shape. Next, an electromagnetic coil is created adjacent this material. Finally, a second layer of very efficient magnetic material is laid down adjacent the first two layers, forming a magnetic circuit, and having a portion fashioned into a deflectable structure, such as a cantilever beam. The deflectable structure has at least a portion that is suspended over or adjacent to at least one electrical contact. In operation, current passes through the coil, causing the deflectable structure to deflect, and either make or break contact with the electrical contacts. The micro-relay includes a unique unpowered hold feature By integrating an electrostatic actuating capacitor into the micro-relay, an electrostatic force can be generated between the cantilever beam and the substrate of the micro-relay that is strong enough to hold the relay in the "ON" position. Turning the relay "OFF" requires only that the voltage be removed.
52 Microelectromechanical positioning apparatus US965277 1997-11-06 US5962949A 1999-10-05 Vijayakumar R. Dhuler; Robert L. Wood
A microelectromechanical (MEMS) positioning apparatus is provided that can precisely microposition an object in each of the X, Y and Z directions. The MEMS positioning apparatus includes a reference surface, a support disposed in a fixed position to the reference surface, and a stage defining an XY plane that is suspended adjacent to the support and over at least a portion of the reference surface. The MEMS positioning apparatus also includes at least one and, more typically, several actuators for precisely positioning the stage and, in turn, objects carried by the stage. For example, the MEMS positioning apparatus can include first and second MEMS actuators for moving the stage in the XY plane upon actuation. In addition, the MEMS positioning apparatus can include a Z actuator, such as a thermal bimorph structure, for moving the stage in the Z direction. As such, the MEMS positioning apparatus can precisely position the stage as well as any objects carried by the stage in each of the X, Y and Z directions. As a result of the construction of the MEMS positioning apparatus, the MEMS positioning apparatus can also be fabricated in an affordable, reliable and reproducible manner without compromising the precision alignment provided by the MEMS positioning apparatus.

The slot is open at one end to the top surface of the first flange and extends downward to the core. The slot is positioned on the top surface of the first flange opposite the lead pin. The channel extends from the lead pin across to the end of the slot near the core. The width of the channel and the slot are adapted for guiding a winding wire therethrough.
55 High voltage disconnect/reconnect switching device US672239 1984-11-16 US4628396A 1986-12-09 D. Frank E. Flemming
The apparatus comprises a high voltage disconnect and load isolation switch. During normal operation commercial power is conducted through a pair of contacts "a" and "b" to a load. When a high voltage (HV) component is detected by an HV pulse detector, a command from the HV detector opens a secondary power interrupter while simultaneously activating the opening of contacts "a" and "b". A surge protector conducts some of the HV energy greater than the source, or commercial power, to ground. As contacts "a" and "b" open, HV ground probes are positioned at a slight distance (dielectric constant equal to the commercial power source) from these contacts. These probes provide a ground source for an HV component throughout the complete transition of contact "b" to the rest position, which will be at ground potential. There is now full isolation from the source power supply.
56 Planar contact array switch having improved ground path for dissipating electrostatic discharges US498046 1983-05-25 US4456800A 1984-06-26 John P. Holland
An improved planar contact array switch having reduced susceptibility to electrostatic discharge includes a printed circuit board which carries at least one switch contact foil pair. Sandwiched between the circuit board and an insulative overlay is a dome-shaped disc which, when depressed, completes an electrical circuit between the switch contact foil pair. Bordering the periphery of the printed circuit board so as to bound the area occupied by each of the switch contact foil pair is a ground foil which advantageously is provided with at least one inwardly extending charge conductive foil which runs adjacent to each of the switch contact foil pairs for conducting any electrostatic discharge which penetrates the overlay within the area bordered by the ground foil. To facilitate the conduction of electrostatic discharges to the perimeter ground foil through the charge conductive foil, a spark gap is provided between each of the switch contact foil pairs and the charge conductive foil so that an electrostatic discharge may jump the spark gap and be conducted via the charge conductive foil on the ground plane to circuit ground.
57 Overvoltage protective module US260807 1981-05-05 US4380038A 1983-04-12 Maurice Roudeau
The overvoltage protective module comprises a two-terminal overvoltage protective element positioned in a recess of an insulating body. Two conducting strips are held in the bottom of the recess and have flexible ends located one above the other below the second terminal of the element. A grounding plate, secured to a body face, has a hole crossed by the element. A detachable closing cap abuts against the first terminal of the element to drive the element into contact with a flexible end of one conducting strip by combined translation and rotation relative to the grounding plate. To ground test the circuit connected to the upper strip, an end of the upper strip is disconnected from the end of the lower strip and connected to the second terminal of the element when the cap is at an intermediate stationary position of its down stroke. The end of the upper strip is forced against the end of the lower strip by the second terminal of the element at the end of the rotation of the cap, for protecting the circuits connected to the two strips.
