The subject disclosure relates to a coil module assembly for a bi-directional clutch assembly having at least one active clutch. The coil module assembly includes a housing having an actuator housing portion and a PCB housing portion. An electromagnetic actuator is disposed in the actuator housing portion for effectuating pivotal movement of the active strut from an unlocked position to a locked position in response to an energization of the electromagnetic actuator. An integrated printed circuit board (PCB) is disposed in the PCB housing portion and is in electrical communication with the electromagnetic actuator for selectively energizing the electromagnetic actuator. The housing further includes a thermally decoupled housing portion which is disposed between the actuator housing portion and the PCB housing portion for thermally decoupling, i.e., reducing heat transfer, from the electromagnetic actuator to the PCB during selective energization of the electromagnetic actuator.

A base includes first to third projected portions. A sealing surface of the base is opposed to the housing and equipped with a sealing member. An attachment portion outside the sealing surface is screwed with the housing. A first projected portion projects from the attachment portion toward the housing. The second and third projected portions project relative to the sealing surface toward the housing. A recessed portion between the sealing surface and the first projected portion partially receives and fitted with a spigot protrusion of the housing. The second projected portion is located inside the third projected portion, and the third projected portion is located inside the recessed portion in the radial direction. The second and third projected portions extend along the circumferential direction. The first to third projected portions have projected tip end surfaces located in a same plane and in contact with the housing.

A base of a case has an inner groove portion, which surrounds a circuit board, and an outer groove portion. A first projected portion of a connector is inserted in the inner groove portion via a first seal portion. A second projected portion of the connector is inserted in the outer groove portion via a second seal portion. The first seal portion and the second seal portion are formed of the same material and are interposed between a periphery of an opening of the case and the connector. The first seal portion in the inner groove portion is in contact with the first projected portion of the connector to water tightly seal an accommodation space formed in the case. The second seal portion in the outer groove portion is in contact with the second projected portion of the connector to restrict vibration of the connector.

A linear vibrating motor is provided in the present disclosure. The linear vibrating motor includes a housing, a vibrator, a stator and an elastic part. The vibrator and the stator are received in the housing, the elastic part suspends the vibrator. The stator includes a coil and a coil support supporting the coil. The coil support includes a supporting plate, a pair of supporting arms and a pair of supporting legs. The supporting plate supports the coil, the pair of supporting arms extends from ends of the supporting plate respectively, and the pair of supporting legs extends from ends of the supporting arms respectively and is opposite to the supporting plate. The vibrator comprises a groove to receive the supporting plate, and the vibrator is partially positioned between the pair of supporting arms.

A control system and method for controlling electromagnetic drive pumps as, for example, electromagnetic driven membrane pumps are provided in which the control system is formed by at least one microprocessor and at least one sensor, whose microprocessor controls the power supply to at least one electromagnet whose changes in emitted magnetic field causes at least one moving part, directly or indirectly, to perform an oscillating pumping movement. The control system includes at least one positioning sensor which senses the moving part's position in the electromagnetic driven pump. By using the positioning sensor's measurements, the pump can be controlled with great accuracy.

A piston pump configured to pump a fluid and including an inlet channel, an outlet channel, a piston, an armature, an elastic element, a first check valve, a piston chamber, a longitudinal axis, a winding support, and a coil. The piston is movably supported parallel to the longitudinal axis in a piston chamber and has a first face with a piston channel inlet, a second face with a piston channel outlet, and a piston channel connecting the piston channel inlet and the piston channel outlet. The piston is biased in a first axial direction by the elastic element. The first check valve is arranged in the piston channel. The coil has at least one winding arranged on the winding support. The inlet channel is configured to communicate with the piston channel inlet and the outlet channel is configured to communicate with piston channel outlet.

A vibratory actuator includes a vibration body, a contact body, a base, a holding member, and a flexible substrate. The vibration body includes an elastic body and an electro-mechanical energy conversion element. The contact body is in contact with the elastic body and relatively moves with the vibration body due to vibration of the vibration body. One end of the flexible substrate is arranged along a first surface of the holding member and is folded back with respect to an end portion of the holding member toward a second surface of the holding member on a back side of the first surface, and an other end of the flexible substrate is supported by a portion of the base. The flexible substrate separates from the second surface to form a U-turn portion so that the one end and the other end of the flexible substrate are electrically connected.
