Pressure Controllers Used in Sounding Rocket Payload Attitude Control Systems

Pressure controllers from Alicat Scientific have been selected for use in NASA sounding rockets to control payload attitude. The payload sections of some NASA sounding rockets are required to achieve pointing accuracies of finer than 1 arc second (1/3600 of a degree). Conventional attitude control systems (using solenoid valves) introduce too much shock and vibration, and are imprecise. NASA contractor Northrop Grumman chose the Alicat absolute pressure controllers for use with the rockets’ delicate optical instruments.

Creating a Fully Automated Pharmacy Warehouse

Previously, the walk from the sales counter of the pharmacy to the medication drawer wasted valuable time. Today, the fully automated picking system for European pharmacies by KLS requires only eight seconds. Image-based Cognex DataMan® 500 barcode readers can now guarantee rapid resupplying from the warehouse.

Optimized Machine Capability Through Mechatronics: Packaging for the Future

Mechatronics can be defined as the science to optimize the performance and capabilities of machines using a multi-domain synergistic design approach. It is also described as the combination of mechanical, electronic, computer, software, control, and systems de - sign engineering. Simply put, this concept enables machine builders to produce machines that produce the highest quality at maximum throughput. Additionally, it empowers manufacturers to make incremental improvements to existing assets to ultimately meet or exceed core key performance indicator (KPI) targets.

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.

Crew Test Module Provides Launch Escape System

New Shepard rocket-propelled vehicle

Blue Origin Kent, WA 253-872-0411 www.blueorigin.com

Blue Origin has received funding from NASA’s Commercial Crew Development (CCDev) initiative to develop a composite crew test module and a launch escape system for its commercial spaceflight vehicle. The New Shepard system is a rocket-propelled, vertical-takeoff, vertical-landing vehicle designed to routinely fly multiple astronauts into suborbital space. In addition to providing the public with opportunities to experience spaceflight, the New Shepard system will also provide frequent opportunities for researchers to fly experiments into space and a microgravity environment.

Removing Digestive Tumors With a Therapeutic Endoscopy Teleoperation Robot

Endo Tools Therapeutics (ETT) is a medical device company based in Brussels, Belgium that was established in 2008. The company was formed after an innovative research project started in 2004 at Erasme Hospital (Université Libre de Bruxelles) and the faculty of engineering (Beams department, Université Libre de Bruxelles), based on the need for gastroenterologists to have more degrees of freedom when maneuvering an endoscope.
