Abstract: An electromechanical relay is provided with a housing, a relay assembly within the housing, and a data collection cover enclosing the relay assembly within the housing. The data collection cover includes sensing members that extend in toward the relay assembly and engage disconnect switches of the relay assembly. The sensing members transmit analog signals to an analog-to-digital converter that converts analog signals to digital signals. The cover then stores, displays and/or communicates the digital information.

Abstract: An ignition apparatus includes a transformer having a central core, a primary winding disposed thereabout, a secondary winding disposed outwardly of the primary winding, and an outer core or shield disposed outwardly of the secondary winding. The central and outer cores and the primary and secondary windings define a magnetic circuit through which magnetic flux flows during various phases of operation. An end-of-spark natural ringing of the secondary voltage is suppressed and limited by a control winding disposed in relation in the magnetic circuit. The control winding has a pair of terminals across which is connected a diode. The diode is oriented so that during a spark event, it is reverse biased but after the spark event it becomes forward-biased when the secondary voltage is positive so as to selectively facilitate dissipation of any residual electrical charge. Ringing is further suppressed by a resistor connected across the primary winding, or selectively connected across the primary winding using a controlled switch.

Abstract: A relay for high frequency instruments and a reverse power protection circuit for high frequency instruments are described herein. The relay is inexpensive to construct, permits good impedance matching up to approximately 5 GHz, and can be easily mounted on a coplanar waveguide transmission line. The circuit can open the relay in response to a reverse power condition in as little as 8 microseconds and provides both good grounding and functions reliably up to 4 GHz.

Abstract: A coaxial reverse power protection relay using a conductive elastomeric tube and a conductive body. The relay includes a reed switch enclosed within the central channel of the conductive body. The tube concentrically surrounds the reed switch within the channel. The tube retains the reed switch in place and serves as a conformal ground. A magnetic coil is wound around a portion of the body. When energized the coil produces a magnetic field which closes the reed switch. When de-energized, the coil's magnetic field ceases, opening the reed switch. The reed switch, along with center contacts form a center conductor within the channel of the relay body. The body and elastomeric tube form an outer conductor. The relay is impedance matched to RF connector and instrument transmission line impedances. A nonuniform impedance occurring along the length of the reed switch is balanced by the conforming tube walls. The internal wall of the conductive body has a retention thread in the vicinity of the reed switch. Such threading holds the tubing in place during installation.

Abstract: A relay, including a first fixed contact, a second fixed contact, a movable contact piece having first and second movable contacts, a contact piece holding unit configured to hold the movable contact piece, a magnet for arc extinguishing, and a debris suction unit configured to exert a magnetic force to suck debris, is disclosed. A first contact position between the first fixed contact and the first movable contact is located between the magnet for arc extinguishing and the contact piece holding unit in a longitudinal direction of the movable contact piece. The debris suction unit is disposed so that the first contact position does not overlap a region between the debris suction unit and the contact piece holding unit. A magnet force exerted by the debris suction unit in the contact piece holding unit is larger than a magnetic force exerted by the magnet in the contact piece holding unit.
