Abstract: A thin displacement driving device includes a first movable plate, a second movable plate, an axial limiting unit, a first actuator and a second actuator. The axial limiting unit limits the moving direction of the first movable plate and the second movable late. The first actuator has a first shape memory alloy wire coupled to the first movable plate, and the second actuator has a second shape memory alloy wire coupled to the second movable plate. Movement of the first movable plate by the actuation of the first actuator will trigger movement of the second movable plate, and movement of the second movable plate by actuation of the second actuator will trigger movement of the first movable plate.

Abstract: The invention refers to an electric linear motor comprising at least one linear stator designed to be located in a fixed correlation to an environment, particularly building, and at least one mover designed for connection with an element to be moved and co-acting with the stator, which motor comprises a stator beam supporting said at least one stator, which stator beam has at least one side face carrying ferromagnetic poles of said stator spaced apart by a pitch, and which mover comprises at least one counter-face facing said side face(s) of the stator beam, in which counter-face electro-magnetic components of the mover are located.

Abstract: Method and device for controlling the electrical variables and/or LLM currents of LLM coils of an LLM stator, the movement of a first transport unit is controlled by an associated first transport controller, the movement of a second transport unit is controlled by an associated second transport controller, and a control unit checks whether the first transport controller intends to specify a first controlled variable for an LLM coil and whether the second transport controller simultaneously intends to specify a second controlled variable to the same LLM coil. In this case, either an additional controlled variable, which is derived from the first controlled variable and/or the second controlled variable using a predetermined function f (Ux=f(Ux?, Ux?), or Ux=f(Ux?) or Ux=f(Ux?)), is specified for the LLM coil, or the coil terminals of the LLM coil (Lx) are short-circuited.

Abstract: A wireless headset comprising a sound transducer, said sound transducer and a wireless power receiver. The sound transducer comprises a sound transducer coil configured to at least one of convert a first electrical signal to a first sound signal and convert a first sound signal to a first electrical signal comprising first audio information. The wireless power receiver is configured to receive wireless power through an antenna comprising said sound transducer coil.

Abstract: Disclosed herein is an actuator wherein, when in use, a magnetic force holding assembly maintains the slider in substantial repulsion at the first position and substantial attraction at the second position.

Abstract: A component comprises a non-metallic core having an outer surface, a first catalyst deposited onto at least a first portion of the outer surface of the non-metallic core, a second catalyst deposited onto at least a second portion of the outer surface of the non-metallic core, an electrical interface, and a metallic coating. The electrical interface is plated onto the first catalyst, and includes a first interface layer electroless plated onto the first catalyst. The metallic coating is plated onto the second catalyst.

Abstract: Provided is a coil assembly having improved heat resistance for use in a control rod driver, in which the heat resistance of coils is improved to increase the lifespan thereof and the deterioration of the coils and the fall of a control rod are thus securely prevented from occurring due to continuous operations of the control rod driver during an automatic load follow operation, thereby improving the safety and economic feasibility of a nuclear power plant, and a method for manufacturing the same.

Abstract: A high-resolution positioning device has a stator and a rotor, a coil array, arranged on the stator, and having at least three groups of flat coils, wherein each group has at least two single coils and the coil array encloses a free space on the stator, also having permanent magnetically-excited circuits that are situated on, against or in the rotor and form a magnet array which likewise encloses a free space, wherein the free spaces accommodate a position measuring system which has a measuring head having sensors, and an area scale. The device is in the form of a freely suspended, magnetically controlled six-dimensional drive, wherein the measuring head is situated in the coil array free space and the area scale is situated in the magnet array free space, and the rotor is free of drive-related electrical or electronic and, in this regard, live parts.

Abstract: An electromagnetic inertial actuator includes a support base and a parallel arrangement of a first flexure part, a voice coil motor part, and a second flexure part. The parallel arrangement is cantilevered from the support base.
