Abstract: A vehicle hood covering an underhood object includes an inner surface of the vehicle hood facing the underhood object and spaced from the underhood object, and an outer surface of the vehicle hood opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the vehicle hood. The local energy absorber is a multiply-connected structure. The local energy absorber includes a wall defining an interior surface having symmetry about a central plane normal to the inner surface of the vehicle hood. A plurality of apertures is defined in the wall symmetrically about the central plane to initiate buckling and fracture in the wall during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.

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 lightweight and portable inflatable assembly includes an inflatable structural component and a chemical reaction based inflator device. The inflatable structural component includes a flexible housing defining a cavity. The inflatable structure is uninflated in a first operational mode and filled with an inflation fluid retained for at least 4 hours in a second operational mode. At least one primary and at least one secondary charge unit are in fluid communication with the cavity. The primary charge unit includes a first gas generant material configured to generate a first predetermined volume of inflation medium for filling the cavity, while the secondary charge unit includes a second gas generant material configured to generate a second predetermined volume of inflation medium for filling the cavity in the second operational mode. The second predetermined volume is ≤about 40% by volume of the first predetermined volume.

Abstract: A method for securing sandwich structures together, especially vehicle structures. In one embodiment, two sandwich structures are perpendicularly secured together, where a first one of the sandwich structures includes a micro-truss core having one unit cell geometry and second one of the sandwich structures includes a micro-truss core having different unit cell geometry. The micro-truss core of the second sandwich structure includes a micro-truss extension fabricated at the same time as the micro-truss core and having the same unit cell geometry as the micro-truss core for the first sandwich structure. The extension is inserted in an open area between face sheets in the first sandwich structure so that it abuts against the micro-truss core in the first sandwich structure.
