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.

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 window application, the seal force can be selectively reduced during movement of the window and increased when the window is stationary, thereby selectively changing seal effectiveness. Active materials refers to several different classes of materials all of which exhibit a change in at least one attribute such as dimension, shape, and/or flexural modulus when subjected to at least one of many different types of applied activation signals, examples of such signals being thermal, electrical, magnetic, stress, and the like.

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 tailored for vehicles such as in a vehicle door application, door opening and closing efforts can be minimized yet seal effectiveness can be maximized.

A fixture device generally includes a base member, a reconfigurable pad disposed on the base member, wherein the reconfigurable pad comprises a shape memory material configured to selectively conform to a surface contour of a workpiece, and an activation device in operative communication with the shape memory material.
摘要:
A panel having active material based segments, wherein the segments define a hinge location that can be selectively stiffened or folded on demand. The active material based segments include an active material such that activation of the active material by an activation device can allow folding of the panel, can effect self-folding of the panel, or can serve to lock the panel into a fixed position when not activated. In this manner, the panel that can be variously stiffened or folded on demand. Other embodiments include forming the panel of the active material such that the panel can be compacted and stowed upon activation of the active material to change the modulus properties thereof.
摘要:
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.
