Abstract: A camera system includes a body defining a cavity therein, and a camera attached to the body within the cavity and including a lens. The camera system also includes a shape memory alloy transitionable between a first state and a second state in response to a thermal activation signal, and a wiper configured for wiping debris from the lens. The wiper is attached to the camera and is actuatable by the shape memory alloy. The shape memory alloy transitions between the first state and the second state to actuate the wiper so that the wiper contacts and translates across the lens and thereby wipes debris from the lens.

Abstract: A closure release device includes a housing fixedly attached to a closure and an actuating lever rotatably disposed on an axis of rotation on the housing. A crank lever is rotatably disposed on the axis of rotation. A coupling member is to selectively couple the actuating lever to the crank lever for rotation together. A shape memory alloy (SMA) actuator is to selectively cause the coupling member to selectively couple the actuating lever to the crank lever. The SMA actuator is electrically actuated. The crank lever is to connect to a latch to selectively release or engage the latch in response to a coupling state of the actuating lever with the crank lever and an actuation state of the actuating lever.

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.

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: An inflatable structure includes a top end cap, a bottom end cap, a bladder, a plurality of tethers, and an adjustment mechanism. The bladder is attached to the top and bottom end caps and configured to hold pressurized air therebetween. The plurality of tethers are disposed within the bladder. Each tether in the plurality of tethers has a first end coupled to the top end cap and a second end coupled to the bottom end cap. When the bladder is inflated, the plurality of tethers restrict a number of degrees of freedom of the inflatable structure and a type of the degrees of freedom. The adjustment mechanism is operable to move the second end of at least one tether in the plurality of tethers to adjust at least one of the number of the degrees of freedom and the type of the degrees of freedom.

Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

Abstract: A textile comprising: i) a fabric including a laced region associated with a surface of the textile; and ii) a thread inlaid through a plurality of points proximate a perimeter of the laced region. Tightening the thread causes opposite sides of the laced region to be cinched together, thereby forming the laced region into a flap associated with a second surface of the textile opposite the first surface. The textile further comprises a listing wire disposed in the flap. The fabric forms a plurality of perforations within the laced region. The listing wire may be accessed by an attachment device through at least one of the plurality of perforations.
