Engineering better Army technology (Part 1): Overmatch
Overmatch in weapon systems "means we have an advantage in every sense of the word ... it's much bigger than lethality," says Keith Jadus, acting director of the lethality portfolio for the Office of the Deputy Assistant Secretary of the Army for Research and Technology. This article looks at issues in developing technologies with extended range, precision, using direct energy, and more.

Conquering Complexities:
Mold-making techniques make complicated features possible

Designing an injection-molded part with the proper draft, wall thicknesses, radii, and other considerations can be complicated, so when unique features like bayonets and gears are integrated into your geometry, another layer of complexity can arise. Proto Labs' Gus Breiland has some valuable advice for you if your part requires intricate features.

Graphic front-panel displays

NFi Graphic Overlay Panels from Nameplates For Industry are custom made using the Texturite process, which starts with a hard-coat clear material such as Lexan or Mylar to provide clear, distortion-free front-panel graphic overlays for LEDs, LCDs, and vacuum fluorescent displays. Unlike conventional overlays that add the window, the windows are the base material for optimum clarity and durability. Overlay panels can incorporate high-resolution graphic images that are digitally printed on the polycarbonate or polyester subsurface.

New wind-power concept inspired by birds
Taking a cue from the natural airfoil design of bird wings, the creative wizards at pneumatics specialist Festo have come up with a totally new concept for generating wind power. The horizontal DualWingGenerator uses an opposing-wing design to generate electricity and is especially effective at low wind speeds. This video explains the simple mechanical inner workings. A really fresh -- and inspiring -- design.
