    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： 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.
