摘要： An external adjustment device includes at least one permanent magnet configured for rotation about an axis with a first handle extending linearly at a first end of the device and a second handle at a second end of the device, the second handle extending in a direction substantially off axis to the first handle. The external adjustment device further includes a motor mounted inside the first handle and a first button located in the proximity to one of the first handle or the second handle, the first button configured to be operated by the thumb of a hand that grips the one of the first handle or second handle. The first button is configured to actuate the motor causing the at least one permanent magnet to rotate about the axis in a first direction.

摘要： The present invention relates generally to the field of floor mats. More specifically, the present invention relates to a magnetic mat device that prevents a user from wasting excessive amounts of time searching for nuts, bolts, screws, sockets, or other parts that fall onto the floor while working. The device is primarily comprised of a body, further comprised of a top layer, a middle layer, further comprised of at least one magnet, and a bottom layer. Further, the top layer is comprised of a top surface that helps prevent against slips as well as stains from oils and other liquids. Further, the bottom surface is comprised of protrusions that prevent the device from sliding on the floor. The device is also comprised of a side surface comprised of at least one magnet to attach multiple devices together to encompass any size workstation.

摘要： A fan driving circuit includes a primary winding, an activating capacitor, a control circuit, a switch circuit and a secondary winding. The primary winding and the activating capacitor are electrically coupled to an external power source. The control circuit generates a control signal. The switch circuit is electrically coupled to the first winding. The switch circuit is also electrically coupled to the activating capacitor. The switch circuit has at least one control terminal electrically coupled to the control circuit for receiving the control signal. The secondary winding is electrically coupled to the switch circuit. The secondary winding is electrically coupled to the switch circuit. The secondary winding electromagnetically drives a fan according to a flowing direction of its driving current. The switch circuit conducts the secondary winding's driving current's flowing direction based on the control signal's voltage level.

摘要： A superconducting AC switch system includes a switch network configuration comprising a Josephson junction (JJ) coupled to a transmission line having a transmission line impedance, and a magnetic field generator that is configured to switch from inducing a magnetic field in a plane of the JJ, and providing no magnetic field in the plane of the JJ. An AC input signal applied at an input of the switch network configuration is passed through to an output of the switch network configuration in a first magnetic state, and substantially reflected back to the input of the switch network configuration in a second magnetic state. The first magnetic state is one of inducing and not inducing a magnetic field in a plane of the JJ, and the second magnetic state is the other of inducing and not inducing a magnetic field in a plane of the JJ.

摘要： The invention relates to an electrotechnical coil, to a method for producing same, and to an electromagnet or an electric machine comprising at least one such coil. The aim of the invention is to produce and use an electrotechnical coil for achieving an increased slot fill factor reliably and easily in a reproducible and economical manner. This is achieved in that the method according to the invention has the steps: step A: casting an electrotechnical coil with at least one winding which runs about a coil axis; and step B: shaping the coil, thereby changing the cross-section Q, Q′ of the at least one winding, such that the centroid FS, FS′ of the cross-section Q, Q′ of the at least one winding is displaced at least partly in the radial direction R relative to the coil axis A.

摘要： A series of the relay of the electromagnetic launcher with a gun and a floating launch platform to launch projectiles in space, wherein the projectile is accelerated along a path using electromagnetic force until the projectile reaches a desired direction and position. The direction of the path is determined by orienting the path in the desired direction using a catcher. the catcher and rail gun projectile as high above as possible, coming close to near space. When the said projectile will reach the last platform, it will be launched by the railgun and ignite its rocket engine to take the payload in space or as required to eliminate the need for large rocket boosters to launch the projectile.

摘要： An electromagnetic valve has a solenoid, which includes a coil, a plunger, a fixed core, and a plunger spring. The fixed core is E-shaped and has a base, a first outer leg, a second outer leg, and a central leg. The first outer leg, the second outer leg, and the central leg extend from the base. The first outer leg has a first outer attraction surface configured to attract the plunger. The second outer leg has a second outer attraction surface configured to attract the plunger. The central leg has a central attraction surface configured to attract the plunger. The central attraction surface is larger in area than each of the first and second outer attraction surfaces.

摘要： An electro-mechanical unlocking device that includes a locking state, a holding state and an unlocking state. The unlocking device includes an arming solenoid and a holding solenoid. In the locking state the arming solenoid moves an arming assembly, which moves a crank and which moves a holding armature from a second position to a first position. In the holding state the holding solenoid is energized and the arming solenoid is de-energizing, which allows the arming armature to moves from the first position to the second position. In the unlocking state the holding solenoid is de-energized, which allows the holding armature and the arming link to move from the first position to the second position. In the locking and holding states a sear blocks the path of the striker and in the unlocking state the sear does not block the path of the striker.
