, programming a vehicle event recorder with location-specific information can be a complex, arduous, and error-prone process. A variety of Z-shaped steel sheet pilings are known in the prior art. Z-shaped sheet pilings are typically produced in different sizes characterized by their approximate weight in pounds per square foot (“psf”). Typical sizes include the PZ22, PLZ23, PLZ25, PZ27, PZ35, and the PZ40. Such sheet pilings have been produced by Bethlehem Steel Corporation and United States Steel Corporation.
However, sheet pilings known in the prior art do not provide much versatility with respect to the placement of steel near the junction. This has been found to limit the ability to strengthen the piling with respect to transverse stresses (i.e., those stresses oriented perpendicular to the longitudinal axis of the sheet piling).
Hence, it would be useful to provide sheet pilings which can be manufactured efficiently and with greater selectivity for strength. Advances are continually being made in the area of manned space flight and this area of exploration will certainly play an important role in the progress of science over the next several decades and centuries. As the reaches of manned space flight expand, new technologies are needed protect those who venture into the harsh vacuum above, while also economizing resources for longer missions and lowering the costs associated with space travel. With these goals in mind, improvements may be made to current systems and methods for spacecraft environmental controls and life support.
One aspect of environmental control and life support is air revitalization. Oxygen gas, carbon dioxide gas, and water vapor within the breathable air of an enclosed crew cabin of a spacecraft must be maintained at levels to support life. Active air revitalization may help to maintain the levels. Typical spacecraft generally rely on separate systems to remove carbon dioxide and water vapor from the crew cabin. Resources are not typically shared between the systems. Further, typical air revitalization systems rely solely on fans to pass air therethrough without taking advantage of incidental pressure differentials to move air. Additional disadvantages may exist. Temporary IVC filters are placed much like permanent filters, but are designed so that they may be retrieved in a separate endovascular procedure, generally from a femoral vein or internal jugular vein approach. Most of the currently available temporary filters include a hook-like feature with which they can be captured and received within a catheter or sheath for removal by employing a gooseneck snare or a multi-
