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.

Abstract: Aspects of the present disclosure are directed towards environmental based location monitoring. Environmental based location monitoring can include collecting, a first set of image data that corresponds to a first set of environmental characteristics existing within a bounded area encompassing a hardware element of the computer and determining an environmental difference based on a difference between a first location corresponding to a geographic position of the hardware element relative to the first set of environmental characteristics and a second location corresponding to an approved geographic position of the hardware element. Environmental based location monitoring can include determining that the environmental difference does not satisfy a threshold and executing a reaction sequence in the computer, in response to determining that the environmental difference does not satisfy the threshold.
