  • Publication number: 20070040701
    Abstract: A method for identifying available parking spaces. The method includes receiving data about a parking space from a vehicle, the data including a geographic indicator associated with the parking space. The data is stored in a database of available parking spaces. A geographic location is received from a parking space requestor. The database is searched for an available parking space within a proximity of the geographic location. If an available parking space within a proximity of the geographic location is located in the database, a geographic indicator associated with the available parking space is transmitted to the parking space requester.

  • Publication number: 20060267376
    Abstract: 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.

  • Publication number: 20060261109
    Abstract: An active material based releasable fastener system for a vehicle carrier generally comprises a loop portion and a hook portion. A selected one of the hook portion or the loop portion is disposed on a surface of the carrier whereas an other selected one of the hook portion and the loop portion is disposed on a contact surface on which the carrier is disposed. When the loop portion and the hook portion are pressed together they interlock to form a releasable engagement being relatively resistant to shear and pull forces and weak in peel strength forces. The hook portion comprises a plurality of hook elements comprised of an active material. An activation signal applied to the active material causes a change in shape orientation, flexural modulus property, or a combination thereof to the hook elements that effectively reduces the shear and/or pull off forces in the releasable engagement.
