    摘要： A metrology system includes a laser, a position sensitive detector array, a first collimator, a second collimator, and a mirror. The position sensitive detector array and the first collimator are positioned at a reference point. The second collimator and the mirror are positioned at a point target at a distance from the reference point. A laser beam is alternately provided to the first collimator and the second collimator by optical fiber. The position sensitive detector array measures position data from a first laser crosshair generated by the first collimator and from a second laser crosshair generated by the second collimator. By alternating the activation of the first collimator and the second collimator it is possible to measure 5 degrees-of-freedom for the point target. A metrology system processing unit provides analog data processing. The metrology system that is suitable for, but not limited to, facilitating active compensation of large spacecraft structures.

    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.
