Abstract: A microfluidic lab-on-a-chip (LOC) device, microfluidic systems, and associated methodology are described that allow for intelligently collecting environmental DNA (eDNA) and their associated metadata. Optical spectroscopy is integrated with filtration membranes on the microfluidic device. The microfluidic LOC device and systems can be used for selectively capturing targeted species based on optical characteristics and for recording relevant metadata on eDNA acquired by the filtration membranes.

Abstract: A flight control system includes carbon fiber pull rods to substitute in whole or in part for conventional steel cables. The stretch and thermal expansion issues associated with composite cables are minimal, making them much better for the very long flight-control runs on large aircraft and spacecraft, and also on aircraft and spacecraft operating though a wide range of temperatures during flight. In a preferred embodiment, the carbon fiber pull rods are manufactured by winding a resin-impregnated carbon tow around a pair of bobbins, one of which is fixed and one of which is rotatably mounted. When the second bobbin is rotated, the windings are twisted to form the carbon fiber pull rod, which is then cured to complete the manufacturing process.
