    Abstract: Some on-vehicle devices, such as air dams, air spoilers, and HVAC system baffles, may have movable components that are pulled from one position to another by shrinkage of a linear shape memory alloy (SMA) actuator. Upon an activation signal, the shrinkage of the SMA actuator occurs when it is resistance heated by an electrical current. It is found that useful information concerning the overall intended operation of the on-vehicle device may be obtained by computer analysis of the temporal variation of both current flow through the actuator and its electrical resistance as it is heated to perform its function in the device. A comparison of present current flow and variation of resistance, during activation of the device, with prescribed stored values can reveal malfunction of components of the device as it is being used, in place, on the vehicle.

    Abstract: A process for fabricating a curved beam including a micro-truss structure. In one embodiment, the process includes fabricating the micro-truss structure on a bottom facesheet, where the micro-truss structure is only partially cured so that it is readily bendable, and then forming the partially cured micro-truss structure and bottom facesheet over a curved fixture, where the partially cured micro-truss structure is then fully cured and hardened to its final curved state. A top facesheet is then adhered to a top surface of the micro-truss structure. In an alternate embodiment, a curved bottom facesheet is forced flat against a fixture and the micro-truss structure is formed while the bottom facesheet is secured to the fixture to a partially cured state. The bottom facesheet is then released from the fixture, which causes it to return to its curved configuration causing the micro-truss structure to bend.

    Abstract: A power adjusted seat assembly includes a seat, and is adapted for use when a resting load is present within the seat. The assembly further includes at least one reconfigurable seat structure shiftable between first and second permanent dimensions, orientations, positions, or conditions. An active material actuator is drivenly coupled to the structure. A mechanical transmission is drivenly coupled to the structure, so as to act in concert with the actuator, and is configured to receive and modify at least a portion of the load. The actuator and transmission are cooperatively configured to cause the structure to shift between the first and second permanent dimensions, orientations, positions, or conditions, when the resting load is present and the actuator is activated.

    Abstract: A releasable connection connects a first component to a second component. The second component includes and is manufactured from a Shape Memory Polymer (SMP), and defines a pocket. The first component includes a portion disposed within the pocket. The pocket is deformed from an initial shape permitting insertion of the portion into the pocket to assembly the releasable connection into a connected shape wherein the pocket is deformed to secure the first component relative to the second component. The pocket is transformed from the initial shape into the connected shape by heating the SMP material of the second component to a switching temperature. Re-heating the SMP second component to the switching temperature returns the pocket back to the initial shape from the connected shape to disassembly the releasable connection.

    Abstract: A vehicle, suspension system and method of dampening a force on the suspension system is disclosed. The suspension system includes a damper having a first damping element and a second damping element configured to rotate relative to each other in response to a force received at the suspension system. The second damping element induces an eddy current in the first damping element during relative rotation. A feature of one at least one of the first damping element and the second damping element provides a first electrical resistance to the eddy current during relative rotation in a first direction and a second electrical resistance to the eddy current during relative rotation in a second direction. The first electrical resistance generates a first damping force and the second electrical resistance generates a second damping force.
