Smart Enclosures using RFID for Inventory Management

The NASA Johnson Space Center has developed a method for tracking collections of items in a smart container using radio-frequency identification (RFID) tags with a high level of read accuracy. Automating the tracking of a collection of items (particularly small items) represents a major industrial hurdle due to both tag size and cost. This technology promises to successfully address these hurdles. The smart enclosure innovation can track individual items in the smart containers or receptacles regardless of item placement. The NASA-developed patent-pending technology is available for licensing.

TestEVAL Software to Assist in Mechanical Testing

Goddard Space Flight Center, Greenbelt, Maryland Typically, mechanical test data has been reviewed and processed using a combination of Excel, PDF Viewer, MATLAB, and other tools. TestEVAL provides a central tool for all these tools, and enhances their capability. Having been developed in Python, it is expendable and portable. It uses no proprietary software and an all open-source code base.

Flight Test System for Accurately Predicting Flutter

Armstrong Flight Research Center, Edwards, California Traditional methods of flight flutter testing analyze system parameters such as damping levels that vary with flight conditions to monitor aircraft stability. In the past, the actual flight envelope developed for aircraft operation was essentially determined only by flight testing. The edges of the envelope are points where either the aircraft cannot fly any faster because of engine limitations, or, with a 15% margin for error, where the damping trends indicate a flutter instability may be near. After flight testing, the envelope empirically determined is used for regular operations.

Hermetic Seal Leak Detection Apparatus with Variable Size Test Chamber

A streamlined, cost-effective, sensitive approach to detecting leaks in hermetic seals. Marshall Space Flight Center, Alabama NASA’s Marshall Space Flight Center has developed a unique apparatus ideal for use in nondestructive testing (NDT) of hermetic seals of containers or instrumentation. The device is capable of detecting both large and small leaks and can be calibrated to characterize the relative leak rate. Its simple design does not require specialized gases for pressurization and detection, and eliminates the need for expensive instrumentation such as a mass spectrometer to analyze leaks and achieve high sensitivity. Low in cost and simple to manufacture, the patent-pending technology is ideal for use in many industries, from aerospace applications to food packaging and commercial goods.

Coming Soon - Thermal Management: Heat Pipes, HiKTM Plates, and Vapor Chambers – Selection and Modeling

Heat pipes, high conductivity (HiK™) plates, and vapor chambers are two phase technologies that are often considered for electronics cooling.  All three devices rely on the very high evaporation and condensation coefficients of two phase fluids to reduce the ΔT between the source and the sink for a given power.  When properly engineered for power and mission duration, all of these devices provide passive, reliable cooling.
