Insulative Carbon Fiber Systems for Aerospace Applications

New insulative carbon-fiber composite systems have been developed for use in structural and thermal applications for the aerospace vehicle interface. The sandwich-type composite structure, including carbon fiber and aerogel blanket materials, is based on the previously disclosed family of hybrid laminate composites. Offering unique and tailorable combinations of structural and thermal properties, these insulative carbon fiber systems can be used in vehicle shroud and thermal protection system applications at the aerodynamic interface plane, panels between stages, or fairings for spacecraft equipment space of space launch vehicles. The novel, lightweight, fiber composite laminate system with reduced heat transfer also has increased impact resistance at low temperatures.

Method and Apparatus for Performance Optimization Through Physical Perturbation of Task Elements

This technology can be used in sports psychology, marksmanship training, video gaming, and special forces training.NASA’s Langley Research Center has developed ZONE, an innovative method for improving athletes’ responses to stress, anxiety, and loss of concentration during competition. In the training environment, when the user successfully attains an optimal target state of psychophysiological functioning, the technology informs and/or rewards that user through real-time physical changes in the athletic equipment. For example, in the training setting, a golfer can work toward optimal concentration in the act of putting, leading to improved performance in real situations.

Portable Medical Diagnosis Instrument

Four cutting-edge sensor technologies enable minimally or non-invasive analysis of various biological samples.NASA has developed a novel technology strategy called “The NASA Analyzer” that would provide comprehensive in-flight medical diagnostic capability in a compact, handheld device for human deep-space missions such as Mars. Key features of the technology include the ability to handle multiple sample types (breath, saliva, blood), and the ability to measure virtually any analyte, including future analytes as they emerge. The device provides both non-invasive and minimally invasive sampling capabilities, which will be required during long-duration exploration missions. Breath and saliva are fully non-invasive and can provide critical health assessment information very rapidly. From small blood samples, information about macromolecular analytes, as well as blood cell counts, can be obtained. The device consists of four cutting-edge technologies integrated into a single, compact medical diagnostic tool with wireless (e.g., smartphone) capability. In addition to space applications, this innovative technology will very likely have important spinoffs in medicine and public health on Earth.

Methods and Systems for Non-Invasive Treatment of Tissue Using High-Intensity Focused Ultrasound Therapy

Minimally invasive and non-invasive therapeutic ultrasound treatments can be used to ablate, necrotize, and/or otherwise damage tissue. High-intensity focused ultrasound (HIFU), for example, is used to thermally or mechanically damage tissue. HIFU treatments can also cause mechanical disruption of tissue with well-demarcated regions of mechanically emulsified treatment volumes that have little remaining cellular integrity. For certain medical applications, tissue emulsification may be more favorable than thermal damage because it produces liquefied volumes that can be more easily removed or absorbed by the body than thermally coagulated solid volumes.

NEQAIR v14.x Non-Equilibrium Radiative Transport and Spectra Program

There is a need to calculate the radiative heating rate at the surface of a vehicle entering any atmosphere, (e.g., Earth, Saturn, Titan, Mars, Venus etc). NEQAIR simulates the actual chemical and physical actions and reactions of the gaseous species in high-temperature shock layers. NEQAIR has been NASA’s main radiation code for the past 30 years. It is a line-by-line radiation code that computes spontaneous emission, absorption, and stimulated emission due to transitions between various energy states of chemical species along a line of sight. There have recently been substantial updates to the physics in the code and the computational efficiency in NEQAIR; v14.0 is the first parallelized version that has resulted in calculations speeding up by a factor of approximately 30×.

Systems Engineering Education and Development (SEED) Web Application

This application serves as Web-based management of the Systems Engi - neering Education and Development (SEED) program, and enables the SEED Program Manager to track and manage the applications and assignments. In the past, the handling of the applications and assignments was cumbersome due to a manual process with paper copies of competencies and applicant data. The new system enables the automation of the entire process to streamline determination of both the viability of the applicants and the effectiveness of the program on the participants through the course of their time in the program.

Hammer 1.0

Many software applications have scripting needs including those based on the Goddard Mission Services Evolution Center (GMSEC) framework. In GMSEC, a user may want to automate the actions to take when a sequence of events occurs. Ideally, the scripting solution should allow the use of a familiar programming language and avoid unnecessary constraints. The existing GMSEC Criteria Action Table (CAT) is limited in these respects.
