Processing Time History Data for Display and Analysis

Neil A. Armstrong Flight Research Center, Edwards, California A suite of software tools was developed that enables powerful and efficient processing of time history data. These tools can be used together or independently, offering a variety of capabilities including comparison of time history data files to validate pre-processing activities, conversion from a compressed format to any format suitable for display, and plotting of data from multiple runs and input files using various time-function parameters. Originally developed to process flight test and simulation data, this suite has potential applications for the manufacturing, aerospace, and scientific research industries. These technologies offer a low-cost alternative to expensive, multiple-component data processing and plotting systems.

Prototype Genomics-Based Keyed-Hash Message Authentication Code Protocol

This is targeted for applications without an available public key infrastructure. Goddard Space Flight Center, Greenbelt, Maryland Cryptography and molecular biology share certain aspects and operations that allow for a set of unified principles to be applied to problems in either venue. A DNA-inspired hash code system is presented that utilizes concepts from molecular biology. It is a keyed-Hash Message Authentication Code (HMAC) capable of being used in secure mobile ad-hoc networks. It is targeted for applications without an available public key infrastructure. Ad-hoc does not mean the users are completely unknown to each other. They could be part of a military unit, police, emergency workers, mobile vendors, or any collection of users in a common geographical area that wish to communicate in a region lacking a PKI (Public Key Infrastructure).

Station Spacewalk

Ames Research Center, Moffett Field, California The Station Spacewalk game enables players to virtually conduct NASA repair work on the International Space Station, including jobs critical to help power up the space station so it can continue to operate. Players are provided with a limited quantity of oxygen during which they must complete extravehicular activities (EVAs) and return to the airlock before the air supply runs out.

Product of the Month: December 2014

COMSOL, Burlington, MA, announced COMSOL Multiphysics® software version 5.0 that features product updates, three new add-on products, and the new Application Builder. The Application Builder lets users build applications for use by engineering and manufacturing departments, expanding accessibility to the expertise and to simulation solutions. The Application Builder enables engineers to make available an easy-to-use application based on their COMSOL Multiphysics model. Included with the Windows® operating system version of COMSOL Multiphysics® 5.0, the Application Builder provides tools needed to build and run simulation apps. Any COMSOL Multiphysics model can be turned into an application with its own interface using the tools provided with the Application Builder desktop environment. Other features include the Form Editor, in which the user interface layout can be designed, and the Methods Editor for implementing customized commands. The new version also includes a Ray Optics Module, Design Module, and LiveLinkTM for Revit®.

Motor Drive Software

Teledyne LeCroy (Chestnut Ridge, NY) announced three-phase Motor Drive Power Analyzer software for its HDO8000 oscilloscopes for motor drive embedded control and power section debug. With the addition of three-phase power analyzer capability, and motor speed and torque integration, the drive system can be validated and debugged, and drive and motor power and efficiency measurements may be performed. The software is used by motor, motor drive, variable frequency drive, variable speed drive, industrial automation, and motion control equipment manufacturers. Design engineers that integrate motors into their designs also can utilize the software to validate proprietary controls and complete drive system designs.
