摘要： An energy absorbing device is provided that includes a damper assembly having inner and outer concentric tubes and a piston movable within the inner tube. The damper assembly is configured to form bi-fold valve-type cavities to operatively connect an inner chamber of the inner tube with an outer chamber formed between the inner and outer tubes. A magnetorheological fluid fills the chambers and the bi-fold valve-type cavities. The magnetorheological fluid preferably contains coated magnetic particles at about 10 to 60 percent by volume. Electrical coils adjacent the bi-fold valves are selectively energizable to such that the energy absorbing device provides a tunable damping force, preferably over the entire range of velocities of the piston, especially in automotive applications.

摘要： In an embodiment, a device comprises an active material. Activation of the active material causes deformation within the device to conform to and/or retain an object without engaging the object below a surface of the object. In another embodiment, contact with an object causes deformation within the device to conform to and/or retain the object. In yet another embodiment, an object holder can comprise: a recess, a cover disposed over the recess, and a switch configured to cause the active material to retain a deformed shape in the recess. The cover comprises an active material. The active material is configured to deform into the recess when contacted with an object.

摘要： A dynamic shaft seal assembly for sealing a rotating or reciprocating shaft includes an elastic seal member having at least a portion thereof in sealing communication with the rotating or reciprocating shaft. A shape memory alloy element is in contact with the elastic seal member, the shape memory alloy element being discontinuously disposed about the elastic seal member, and being configured to i) directly apply a compressive force in a radial direction on the seal member against the rotating or reciprocating shaft, and ii) maintain the compressive force on the seal member as a function of temperature. The seal assembly is adapted to seal at a temperature ranging from about −55° C. to about 250° C. Methods including the seal assembly are also disclosed.
