Abstract:
The invention concerns a magnetic actuator comprising a fixed magnetic part (3) which co-operates magnetically with a mobile magnetic part (1) and means (4) for triggering the displacement of the mobile magnetic part (1). The mobile magnetic part (1) comprises at least a magnet (1-1) and the fixed magnetic part (3) has at least two attraction zones (3-2) whereon the mobile magnetic part is capable of adhering. The mobile magnetic part (1) is in magnetic levitation when it is not adhering on one of the attraction zones (3-2) being displaced by magnetic guidance.
Abstract:
A switch with an open state and a closed state suitably includes a cantilever having first and second states corresponding to the open and closed states of the switch, respectively. The switch may also include a magnet configured to provide an electromagnetic field that maintains said cantilever in one of the first and second states. Various embodiments may also include an electrode or electrical conductor configured to provide an electric potential or electromagnetic pulse, as appropriate, to switch the cantilever between the first and second states. Various embodiments may be formulated with micromachining technologies, and may be formed on a substrate.

Abstract:
The invention relates to a mechanically closing, electric microswitching contact (1) comprising two electrically conductive contact elements (7, 8) whose respective contact surfaces come into contact with one another. According to the invention, at least one of the contact surfaces is at least partially comprised of highly-doped conductive diamond, silicon carbide, gallium nitride, boron nitride, aluminum gallium nitride, and/or aluminum nitride.
Abstract:
A power limiting mechanism must be provided especially for protecting electrical-mechanical contactors from welding during power surge resulting from a short circuit. According to the invention, the power limiting mechanism (1) closes a short-circuiting contact (8) of a first short-circuiting branch circuit (9) to disconnect the contactor (20) during a first step and the short-circuiting function thereof is then carried out by an arc (25, 25') having a second short-circuiting branch circuit (19) in a second step. During the disconnection process, the arc is commuted by the short-circuiting contact (8) on the associated conducting bars (16, 18) and flows into an arcing chamber (17) of the power-limiting mechanism, whereby the short circuit is interrupted.
Abstract:
A micro-relay has a flexible monocrystalline structure which is moved by an electromagnetic force to establish a connection between relay contact elements. The micro-relay includes a substrate having a magnetic pathway and one or more coils located over the magnetic pathway. A first contact pad is coupled to the substrate. The monocrystalline structure is suspended over the substrate. A second contact pad and pole pieces are coupled to the monocrystalline structure such that the second contact pad is positioned over the first contact pad, and the pole pieces are located over the coils. A current is applied to the coils to generate an electromagnetic force which flexes the monocrystalline structure toward the substrate, thereby causing the second contact pad to touch the first contact pad. In one embodiment, the coils include insulating spacers located adjacent to the innermost and outermost traces to prevent shorting. 00000
Abstract:
Optical-and-electrical medical systems and methods thereof are disclosed. Such a medical system can include a console, an optical shape-sensing (“OSS”) medical device including an optical-fiber stylet, one or more electrical medical devices, and a relay module for establishing one or more optical or electrical relay connections between the relay module and a remainder of the medical system including the console. The console can be configured for converting reflected optical signals from the optical-fiber stylet into shapes thereof for display. The relay module can include a primary receptacle configured to accept insertion of a medical barrier-piercing plug of the OSS medical device and establish a through-barrier optical connection therebetween. The relay module also can include one or more secondary receptacles configured to accept insertion of a corresponding number of electrical plugs of the one-or-more electrical medical devices and establish one or more under-barrier electrical connections therebetween.
