DC Motor Automates Patient Transfer Device

One of the growing problems facing nurses is a reduced staff, and with it the need to care for overweight patients with very little help. This effort has led to musculoskeletal disorders (MSDs) including back injuries. In fact, 12 percent of nurses leave the profession each year due to back injuries. Those working in nursing homes have an even higher rate of injuries. Until recently, moving a patient was performed manually or with minimal automation.

Motors Keep Telescope Operating in Record-Low Antarctic Temperatures

At Concordia Station in Antarctica, there is a telescope mount that has been operating for a few years. Recently, there was a new record temperature at the Dome C site: -84.6 °C, or -199 °F. Not many things operate well in such conditions, but the telescope mount — which has to move continuously — used for scientific studies by the Laboratoire Universitaire d’Astrophysique de Nice (LUAN) is one of them.

Robots and Vision Combine for Accurate Sheet Metal Cutting

In the general construction industry, many different parts are cut from sheet metal and then welded together on a large machine or vehicle. The trouble arises when the sheets are placed on the cutting table; the larger and heavier they are, the more difficult they are to position on the table. Without proper alignment, the sheet is likely to be cut outside acceptable tolerances, which results in waste and has a negative impact on the welding process. When sheets vary along the X, Y, and Z axes, the issue of exact positioning becomes even more problematic.
