New ‘pin and keeper' quick-assembly sign fastening system The Micro Plastics sign fastener is designed for rapid assembly and disassembly of a sign or other panel to its support structure. The reusable fastener was designed to fit a hole diameter of 5/16 in. to 3/8 in. (8 mm to 9.5 mm) and can be used to fasten two pieces together with total panel thickness from 1 in. to 1.64 in. (25.4 mm to 41.6 mm). Simply squeeze the keeper together and slide onto the pin, then release the keeper. Molded from impact-resistant and UV-stabilized nylon 6/6, the sign fastener is designed to withstand the elements in outdoor applications. Click here for more information.

| Engineer's Toolbox: Injection molding - The guide to looking good First, the bad news: injection molded parts are subject to a host of cosmetic flaws including sink, gate vestiges, ejector pin blemishes, drag marks, texture flaws, knit lines, burns, flash, and inconsistent coloring. The good news is that adherence to basic design rules will eliminate many of these problems.

Video: F-35 fighter testing: 2011 is 'year of firsts' The F-35A flight test team at Edwards AFB, CA, recounts 2011, a productive year of test that they call "the year of the firsts." From flight envelope expansion to mission systems, and KC-10 fuel testing to sensor fusion, the team made great strides testing the F-35A fighter, a conventional takeoff and landing craft that is the smallest, lightest F-35 version and the only one in the series equipped with an internal cannon. The fighter's fraternal twin, the F-35B, is a short-takeoff and vertical-landing craft.

| DARPA takes LS3 (BigDog) robot for a walk | |
| DARPA is developing a semi-autonomous four-legged robot, the Legged Squad Support System (LS3) based on the BigDog system created by Boston Dynamics, to work in tandem with a squad of Marines or Soldiers. Recently, the LS3 prototype underwent its first outdoor exercise, demonstrating the ability to follow a person using its "eyes" – sensors that allow the robot to distinguish between trees, rocks, terrain obstacles, and people. Over the course of the next 18 months, DARPA plans to complete development of and refine key capabilities to ensure LS3 is able to support dismounted squads of warfighters. Features to be tested and validated include the ability to carry 400 lb on a 20-mile trek in 24 hr without being refueled. Also planned is the addition of "hearing" technology, enabling squad members to speak commands to LS3 such as "stop," "sit," or "come here." Hopefully it will be made quieter too.
