Building the Financials to Get Investors Interested

In our last article, we planned out the business chronologically; that is, what we expected to happen and when we thought it would happen. Now, we need to assign costs to the steps in that series of events and roll it up into a standard financial picture that investors, members of your board, employees, and others will understand.

NASA Studies Benefits of Exercise for Astronauts and Public

The 20-G Centrifuge facility at NASA Ames has a radius of 29 feet and is human-rated to 12.5 G. (NASA)NASA's Ames Research Center in California has teamed with the University of Kentucky in Lexington and Vanderbilt University in Nashville, TN, to study ways to reduce adverse effects of space travel on an astronaut’s health. The study is being done on the 20-G Centrifuge at Ames, a machine that creates artificial gravity forces by spinning, and that can simulate up to 20 times the normal forces of gravity experienced on Earth.

NASA Imaging Technology Used to Fight Diabetes

This photomicrograph of a sliced rat beta cell has been processed with the modified NASA imaging technology. Insulin granules are the dark black spots surrounded by the white halo area. The colored borders around the granules are labels added to identify and classify them. (NASA/Tim McClanahan)NASA image processing technology used to explore orbital images of Earth is being modified for use in diabetes research. A team from George Washington University (Washington, DC) and Cornell University (Ithaca, NY) modified the technology, which has increased the speed of the research.

Achieving Positioning Accuracy Goals

The task of choosing the correct mix of motion control components for a successful servo positioning system involves a combination of art, science, and experience. It also includes a little luck, but luck is not needed when you fully comprehend the principle of operation, accuracy, resolution, and repeatability of each component in the system.

CNC Wood Routers Use Drive for Precision Control

The woodworking industry is as advanced and under pressure to deliver high-quality goods quickly as any. One of the most versatile tools devised to quicken production with flat panels of wood is the wood router, used to rout (hollow out) an area in the face of a piece of wood, and used for 3D design, cabinets, sign making, molds, and general material cutting. The table-like device, similar to a metal mill, consists of a broad-based wooden hand plane with a narrow gantry-carried cutting implement projecting beyond its base plate. To guide its computer numerical controlled (CNC) ATC wood routers, WartHog CNC (Soddy-Daisy, TN) turned to YET US’s (Manchester, NH) XtraDrive servo drive system, integrating it into the routers’ precision and power controls.
