    摘要： A power-off hold element for operating in cooperation with an actuator is disclosed. The power-off hold element comprises a material having selectively adjustable rigidity wherein a position or shape of said material is adjustable when energy is applied to increase the temperature of the material above a temperature where the material becomes flexible and the material is rigid in a position or shape when the temperature of the material decreases below the temperature where the material becomes flexible. Also disclosed is a process for operating a power-off hold element for operating in cooperation with an actuator.

    摘要： Reversibly deployable energy absorbing assemblies for impact management generally include a translatable first element, a rigid support structure and a second element having one end fixedly attached to the rigid support structure and an other end fixedly attached to the translatable first element. The second elements are adapted to plastically deform along a predefined buckling path. The predefined buckling path may be uni-modal or multi-modal depending on the desired application and/or impact conditions. Also disclosed herein are methods for operating the energy absorbing assemblies.

    摘要： In some embodiments, a variable stiffness structure is provided having constant stiffness material layers and variable modulus material layers arranged in alternating layers. The variable modulus material layers have a material with a changeable elastic modulus in response to an applied energy field so as to allow reversible coupling and decoupling of stress transfer between successive layers of the constant stiffness material layers to provide a change in a bending stiffness of the variable stiffness structure. The constant stiffness material layers may include segmented portions. The constant stiffness material layers may have segmented portions arranged such that successive layers of the plurality of constant stiffness material layers have overlapping segmented portions. The variable modulus material layers may have shaped structures, for example, corrugation, pillars, striations, tubular, or honeycomb configurations.
