System for Estimating Horizontal Velocity During Descent

Estimates are generated from images and other sensor outputs. The descent image motion estimation system (DIMES) is a system of hardware and software, designed for original use in estimating the horizontal velocity of a spacecraft descending toward a landing on Mars. The estimated horizontal velocity is used in generating rocket-firing commands to reduce the horizontal velocity as part of an overall control scheme to minimize the landing impact. DIMES can also be used for estimating the horizontal velocity of a remotely controlled or autonomous aircraft for purposes of navigation and control.

Eye On Innovation

Creating a Culture of Innovation By Mike Santori National Instruments Business & Technology Fellow National Instruments Austin, TX High-tech companies live and die by their ability to innovate. Creating new products and technologies is essential to gaining new customers as well as keeping current customers. We often associate innovation with visionary individuals who have a great idea and make it successful. But is innovation to be done only by a few visionary figures? National Instruments has certainly benefited from the visionary leadership of our company founders. Under the tutelage of those leaders, we strive to create a culture of innovation, encouraging all employees to think creatively.

David Iverson, Computer Scientist, NASA’s Ames Research Center, Moffett Field, CA

The Inductive Monitoring System (IMS) is a new computer program that monitors gyroscopes that keep the International Space Station properly oriented in space. IMS detects warning signs that precede a gyroscope’s failure. Engineers will add the new software to a group of existing tools to identify and track problems related to the gyroscopes. If the software detects warning signs, it will quickly warn the space station’s mission control center. David Iverson developed the software at NASA Ames.

Laser Drilling of Ceramic Composites to Form Smooth-Walled Holes

Attempts to mechanically drill high-temperature ceramic components can doom them to failure. Even laser drilling can compromise the surface oxidation layer that protects the composite part in high- temperature service.
