Abstract: An actuator includes a solenoid including a coil and a plunger, a switch circuit coupled to the coil, and a control circuit coupled to the switch circuit. The control circuit is configured to receive a feedback signal representative of a plunger position. The control circuit is also configured to provide power to the solenoid via the switch circuit and reduce power to the solenoid via the switch circuit in response to the feedback signal being representative of the plunger being in a full travel position.

Abstract: A solenoid coil discharging circuit includes a rectifier, transistor, and diode. The rectifier is coupled to an alternating current signal, and provides a rectified signal in response to being coupled to the alternating current signal. The transistor is coupled to the rectifier circuit, and biased in on in response to the alternating current signal being coupled to the rectifier, thereby enabling coupling of the rectified signal to a solenoid coil. The diode is coupled to the rectifier, and discharges current from the solenoid coil in response to the alternating current signal being de-coupled from the rectifier. A method of discharging a solenoid coil includes rectifying an alternating current signal to provide a rectified signal, biasing a transistor on in response to the alternating current signal being rectified, thereby enabling coupling of the rectified signal to the solenoid coil through the transistor, and discharging current from the solenoid coil through the diode in response to discontinuing rectification of the alternating current signal.

Abstract: Disclosed is an electromagnetic vibratory pump, comprising a first C-shaped winding and a first magnet. The first C-shaped winding comprises a first coil and a first electromagnetizable member. The first coil covers the first electromagnetizable member, which comprises a first main body, a first leg and a second leg. The legs are connected to the first main body, and the distance between the legs is reduced from a first width to a second width from the first main body. The first magnet swings in a circular tangential direction. A point of tangency of the circular tangential direction is configured apart from the first leg and the second leg respectively by a first minimum distance. The first minimum distance is less than a half of the second width. The first magnet is driven by the first magnetic line of force to move in the first circular tangential direction, and the first magnet is driven by the second magnetic line of force to move in the second circular tangential direction.

Abstract: The magnetic force between the electromagnet and plunger of a magnetic actuator, the electromagnet including a coil generating magnetic flux when the coil is energized, can be increased by locating a near field plate on the electromagnet. The near field plate has a spatially modulated surface reactance configured to focus the magnetic flux within a region of the plunger, such as the central portion of an end portion of the plunger proximate the electromagnet, so as to increase the magnetic force between the electromagnet and plunger. Examples also include permanent magnet based actuators and the use of other magnetic field focusing devices.
