摘要： 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.

摘要： A fluid flow control device includes a resilient substrate translatable between a first flattened position and a second extended position, and an actuator attached to the resilient substrate. The actuator is configured for translating the resilient substrate from the first flattened position to the second extended position. The actuator is formed from a shape memory alloy transitionable between a first state and a second state in response to a change in temperature of the shape memory alloy. A fluid flow control system includes a rotor shield and the fluid flow control device attached to the rotor shield.

摘要： 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.

摘要： A lockable latching device includes a body defining a cavity 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 along the axis between an open position and a closed position. The device includes an annular rotator disposed along the axis and configured for rotating the plunger about the axis. The device also includes an annular latch abutting the rotator that is transitionable between an unlocked state and a locked state. The device includes a first element operably connected to the latch and formed from a first shape memory alloy and a second element operably connected to the latch and formed from a second shape memory alloy.

摘要： 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.

摘要： 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.

摘要： A cushion member having improved variable stiffness for a target is provided. The cushion member comprises a cushion housing having an interior with a variable internal pressure and an exterior surface for receiving the target. The cushion housing is arranged to be deformable and comprises granular particles disposed in the interior of the cushion housing. The cushion housing further comprises hollow particles disposed therein with the granular particles. Each hollow particle is compressible and hollow to define a void therein. The hollow particles have a size, a wall thickness, a material, and a bulk modulus defining infill properties thereof. The hollow particles and the granular particles are arranged to allow the cushion housing to be deformed upon contact with the target. The hollow particles and granular particles define a cushion infill having a variable stiffness based on the infill properties and the variable internal pressure of the interior.

摘要： A lightweight and portable inflatable assembly includes an inflatable structural component and a chemical reaction based inflator device. The inflatable structural component includes a flexible housing defining a cavity. The inflatable structure is uninflated in a first operational mode and filled with an inflation fluid retained for at least 4 hours in a second operational mode. At least one primary and at least one secondary charge unit are in fluid communication with the cavity. The primary charge unit includes a first gas generant material configured to generate a first predetermined volume of inflation medium for filling the cavity, while the secondary charge unit includes a second gas generant material configured to generate a second predetermined volume of inflation medium for filling the cavity in the second operational mode. The second predetermined volume is ≤about 40% by volume of the first predetermined volume.
