Abstract: A multi-pole switch comprising a bottom portion (10) and a top portion (20) divided into a plurality of switch sections, i.e. one switch section per pole, whereby each switch section comprises a set of fixed and a set of movable contacts, and a section for mechanical actuation which causes a displacement of a bar member extending through all the sections and to which the movable contacts are secured. A tripping module (50) can be included in an opening (12) at the top of the section for mechanical actuation, said tripping module comprising a spring for storing of mechanical energy and means actuating an actuating means fixedly connected to the bar member. As a result, the energy stored in the spring can be substantially converted into a displacement of the bar member when the tripping module (50) is released by a signal from an excess current relay (60). The mechanical actuation is preferably included in a corresponding module (40) which is mounted in the switch through a corresponding opening (12) in the bottom of the section.

Abstract: The present technology is generally directed to adjustable shunting systems for draining fluid from a first body region to a second body region. The adjustable shunting systems include an actuation assembly having one or more actuators for controlling the flow of fluid through the system. Each of the actuators can be actuated via energy. The adjustable shunting systems can further one or more energy redirecting elements. Each of the energy redirecting elements can redirect or transmit the received energy to a corresponding actuator. Accordingly, each of the actuators can be independently actuated by applying energy to the corresponding redirecting element.

Abstract: A switching system includes a control circuit that receives On-Off signals indicative of a desired operating state of a switch. The control circuit includes an oscillator that generates a first electrical pulse responsive having a first signal characteristic or a second signal characteristic that is determined by the received On-Off signal, which may be related to a frequency or duty cycle of the pulse. A pulse transformer connected to the oscillator receives the first electrical pulse and outputs a second electrical pulse having the same one of the first signal characteristic and the second signal characteristic as the first electrical pulse. A pulse detection circuit in the control circuit receives the second electrical pulse, determines whether the second electrical pulse has the first signal characteristic or the second signal characteristic, and controls transmission of power and control signals to the switch based on this determination.

Abstract: A switching system includes a MEMS switching circuit having a MEMS switch and a driver circuit. An auxiliary circuit is coupled in parallel with the MEMS switching circuit, the auxiliary circuit comprising first and second connections that connect the auxiliary circuit to the MEMS switching circuit on opposing sides of the MEMS switch, first and second solid state switches connected in parallel, and a resonant circuit connected between the first and second solid state switches. A control circuit controls selective switching of a load current towards the MEMS switching circuit and the auxiliary circuit by selectively activating the first and second solid state switches and the resonant circuit so as to limit a voltage across the MEMS switch by diverting at least a portion of the load current away from the MEMS switch to flow to the auxiliary circuit prior to the MEMS switch changing state.
