So Moog Inc. engineered this testbed to more accurately simulate the forces. It has a probe mounted to a cart that rides on a track and an actively controlled suspension system that supports the drogue. Beneath the refueling probe assembly on the cart is a dynamometer that measures forces and moments on the probe's mast during impact. Past beds were based on a simple drop test.</div> <div class="field-image-promo"> <img class="imagefield imagefield-field_image_promo" width="595" height="335" alt="" src="" /> </div> <div class="field-link-target"> <span>Open In New Window:&nbsp;</span> No </div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Defense Mon, 28 Jul 2014 13:51:00 +0000 39751 at Technology Adds the Sense of Touch to Prosthetic Hands <div class="field-byline"> Stephen Mraz, Senior Editor </div> <div class="node-body article-body">Biomedical researchers at the Veterans Administration are exploring options and developing techniques for directly stimulating nerves to let prosthetic users feel sensations in their artificial hands.</div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Technologies Medical Fri, 25 Jul 2014 18:47:00 +0000 39711 at Five Cost-Cutting Powder-Metal Part Designs <div class="field-deck"> Can’t decide between machining and 3D printing?
