Abstract: A system for controlling fluid flow about a vehicle. The system comprises a fluid flow control device, an obstacle sensor for detecting obstacles, and a controller. The fluid flow control device has a body with at least one surface and an actuation means in operative communication with the surface. The actuation means is operative to alter at least one attribute of the fluid flow control device in response to a control signal. The controller has control logic for generating the control signal in response to the obstacle sensor.

Abstract: A releasable fastener system comprises a loop portion and a hook portion. The loop portion includes a support and a loop material disposed on one side thereof. The hook portion generally includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof, wherein the plurality of hook elements comprises or incorporates a shape memory polymer. When the hook portion and loop portion are pressed together they interlock form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. Introducing a thermal activation signal to the plurality of hook elements causes a change in shape orientation and/or flexural modulus that effectively reduces the shear and/or pull off forces in the releasable engagement. In this manner, disengagement of the releasable fastener system provides separation of the hook portion from the loop portion under controlled conditions. Also disclosed herein are processes for operating the releasable fastener system.

Abstract: A releasable fastener system (10) comprises a loop portion (12) and a hook portion (14). The loop portion (12) includes a support (16) and a loop material (18) disposed on one side thereof. The hook portion (14) generally includes a support (20) and a plurality of closely spaced upstanding hook elements (22) extending from one side thereof, wherein the plurality of hook elements (22) comprises or incorporates a shape memory alloy fiber. When the hook portion (14) and loop portion (12) are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. Introducing a thermal activation signal (24) to the plurality of hook elements (22) causes a change in shape orientation, flexural modulus property, or a combination thereof that effectively reduces the shear and/or pull off forces in the releasable engagement. In this manner, disengagement of the releasable fastener system provides separation of the hook portion from the loop portion under controlled conditions. Also disclosed herein are processes for operating the releasable fastener system.
