    摘要： An airflow control device comprises a body and an active material in operative communication with the body. The active material, such as shape memory material, is operative to change at least one attribute in response to an activation signal. The active material can change its shape, dimensions and/or stiffness producing a change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness to control vehicle airflow to better suit changes in driving conditions such as weather, ground clearance and speed, while reducing maintenance and the level of failure modes. As such, the device reduces vehicle damage due to inadequate ground clearance, while increasing vehicle stability and fuel economy. An activation device, controller and sensors may be employed to further control the change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness of the device. A method for controlling vehicle airflow selectively introduces an activation signal to initiate a change of at least one feature of the device that can be reversed upon discontinuation of the activation signal.

    摘要翻译： 气流控制装置包括与主体可操作地连通的主体和活动材料。 诸如形状记忆材料的活性材料可操作以响应于激活信号改变至少一个属性。 活性材料可以改变其形状，尺寸和/或刚度，从而产生气流控制装置的至少一个特征的变化，例如形状，尺寸，位置，取向和/或刚度，以控制车辆气流，以更好地适应驾驶中的变化 条件如天气，离地间隙和速度，同时减少维护和故障模式的水平。 因此，该装置由于不足的离地间隙而减少车辆损坏，同时提高车辆稳定性和燃料经济性。 可以使用激活装置，控制器和传感器来进一步控制气流控制装置的至少一个特征的变化，例如装置的形状，尺寸，位置，取向和/或刚度。 用于控制车辆气流的方法选择性地引入激活信号以启动在停止激活信号时可以反转的装置的至少一个特征的改变。

    摘要： A reversibly deployable energy absorbing assembly includes a rigid support structure having at least one inlet and at least one outlet; a flexible covering sealingly engaged with the rigid support structure to define an inflatable interior region; a gas source in fluid communication with the at least one inlet; an inlet control valve positioned intermediate the gas source and the at least one inlet; and an actively controlled pressure relief valve in fluid communication with the at least one outlet. The inlet control valve and the pressure relief valve are adapted to provide a response suitable for use in vehicle impact management.
