    摘要： A haptic alert system generally includes an active material based actuator for providing the haptic alert. The active material based actuators refer to the use of several different classes of active 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.

    摘要： Reconfigurable structures include at least one hub, a plurality of arms attached to and extending from the at least one hub, wherein at least a portion of the arm and/or hub defines a node and is formed of an active material. The active material is adapted to change at least one attribute in response to an activation signal, wherein the change in the at least one attribute changes a modulus property, a shape orientation, or a combination of the modulus property change and the shape orientation change to the active material portion. The plurality of arms and at least one hub can form a reconfigurable opening for attaching and releasing a member. Alternatively, the plurality of arms and/or hub can further include a connector for attaching an additional structure. Also disclosed herein are methods for selectively reconfiguring a structure.

    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.
