Disclosed herein is a strut assembly that comprises a piston that is in slideable communication with a housing. The piston comprises a piston head having a channel in operative communication with a fluid that is disposed in the housing. An elastic member and an active element are disposed in the channel. The active element is in operative communication with the elastic member and is operative to change the shape of the elastic member.

The invention relates to a wirelessly controlled electric lock, comprising a lock body (2a), a key cylinder (2b), a turn spindle (3) rotatable by a handle element (3a) internal of the door, the turning of which enables opening of the lock, an opening spindle (4) rotatable by an opening element (5) external of the door, a drive link mechanism (41, 20, 21, 22) enabling the turn spindle (3) and the opening spindle (4) to be coupled with each other for a drive link engagement, such that turning of the opening spindle translates also into a turning motion of the turn spindle. The lock also comprises electrically controlled coupling elements (10, 21, 22, 24, 25, 26), including a piezoelectric actuator (10) which, in a mode activated by an electrical control (12, 31, 33) transmitted (32) wirelessly to the electrical lock, is adapted to fixedly lock a bolt or plunger (10a) which, in its fixedly locked condition, activates said drive link engagement as the opening spindle (4) is turned. Without electrical control of the actuator (10), said bolt or plunger (10a), upon yielding to the weak returning force of a spring, is adapted to disable or not to activate the coupling of the drive link engagement as the opening spindle (4) is rotated.

A low-power-consumption actuator for battery-powered electronic lock includes assembled first and second cases, the second case being provided at a top with a through bore; a piezoceramic/steel sheet assembly consisting of superposed first and second piezoceramic/steel sheet sets, a first end portion of the second piezoceramic/steel sheet set being in a free state; a circuit board electrically connected to the piezoceramic/steel sheet assembly; and a pin unit being located between a top of the first end portion of the second piezoceramic/steel sheet set and the through bore. When the circuit board applies a voltage across the piezoceramic/steel sheet assembly, the first end portion of the second piezoceramic/steel sheet set upward flexes and thereby displaces to push against the pin unit for a pin thereof to protrude from the through bore and interfere with a latch bolt of the electronic lock, so as to actuate the latch bolt.

A latching mechanism is particularly suited for use in latching a slide mechanism, such as used to slidably mount a drawer. The latching mechanism includes a latch assembly comprising a latch lever mounted for movement between a first, second and third positions, a latch tab for selective engagement with a second end of the latch lever, and a piezo electric controller. The controller has a plunger configured to selectively control the movement of the latch lever between the first and second positions, the plunger movable between an extended position corresponding to a first, locked position of the latch lever and a retracted position corresponding to the second, unlocked position of the latch lever, the controller when unpowered preventing the plunger from moving from the extended to the retracted position and the controller when powered permitting the plunger to move from the extended to the retracted position.

Active seal assemblies employing active materials that can be controlled and remotely changed to alter the seal effectiveness, wherein the active seal assemblies actively change modulus properties such as stiffness, shape orientation, and the like. In this manner, in seal applications such as a vehicle door application, door opening and closing efforts can be minimized yet seal effectiveness can be maximized.

The latch actuating mechanism uses both an electric motor and a cylinder lock as alternative means for selectively locking a handle to a cam that in turn can operate a latch mechanism in order to allow the handle to be used to open the latch mechanism. A biasing means urges the handle to the closed position.

Disclosed is an electronic lock. In one embodiment, the electronic lock comprises a body, a barrel having a slot, a pin disposed in the slot, a blocking member disposed in the body to prevent movement of the pin, and an electro-mechanical device. Activation of the electro-mechanical device causes the blocking member to be moved clear of the pin and movement of the barrel causes the pin to be moved out of the slot.

Disclosed herein is a strut assembly 10 comprising a locking device 11 in operative communication with a piston 3, wherein the locking device 11 comprises an active material operative to resist motion of the piston 3 in response to an activation signal. Disclosed herein too is a method of operating a strut assembly 10 comprising displacing a suspended body 60 in mechanical communication with a piston 3; activating an active material in operative communication with the piston 3; and controlling the motion of the suspended body 60.
