Abstract: A lockable latching device includes a body defining a cavity therein and having a central longitudinal axis, and a plunger disposed within the cavity. The plunger has a first end and a second end and is translatable with respect to the body along the axis between an open position and a closed position. The device also includes an annular rotator spaced apart from the body along the axis and configured for rotating the plunger about the axis. The device includes an annular latch abutting the rotator that is transitionable between an unlocked state and a locked state. The device also includes an element attached to the latch and formed from a shape memory alloy that is transitionable between an austenite crystallographic phase and a martensite crystallographic phase in response to an activation signal to thereby transition the latch from the locked state to the unlocked state.

Abstract: A push-push latch includes a slider slidably disposed on a frame. A resilient element is to urge the slider toward an extended state. The slider or the frame defines a cam-track. A pin member is connected to the frame or the slider. The pin member selectably engages a closed course in the cam-track to cause the slider to alternate between a retracted state and the extended state in response to alternating application and removal of an actuating force on the slider. An interference member is on the frame to selectively prevent the pin member from engaging the closed course thereby locking the slider in the retracted state. A pivotable catch is rotatably on the slider to open in the extended state and to close in the retracted state. A shape memory alloy actuator selectively causes the interference member to selectively prevent the pin member from engaging the closed course.

Abstract: A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is opened to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.
