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.

Extended Testability Analysis (ETA) Tool V8.0

This tool provides fast, efficient, and effective diagnostic assessment reports.An assessment of a system’s safety requirements is required early in the design process when cost and time impacts are minimal. These requirements include fault detection, failure isolation, and failure recovery. Systems engineering groups at NASA have been exploring model-based products to better support verification of these safety requirements. One such product involves qualitative failure propagation modeling as a means to achieve early assessment of the system prior to the availability of higher fidelity information. These early development products lack the advanced reporting and analysis capabilities required to address the needs of system designers and domain experts. Therefore, post-processing tools need to be developed to support the interrogation of the model, and the structured reporting required by system engineers.

Lunar Regolith Simulant Sample Collection Mechanism for Remote Operation in a Thermal Vacuum Chamber

The Sample Capture Mechanism (SCM) is a remotely actuated, spring-driven mechanism designed to remotely capture and seal a 15-mL sample in less than 1 second. It was used to capture a 10-g sample of simulated regolith dispensed from a drill in a thermal vacuum chamber with a minimum temperature of –100 ºC. The sample crucible temperature is controllable from ambient temperature to 70 ºC.

Sonar Inspection Robot System

The system surveys interior volume, interrogates structure integrity, and displays real-time video and sonar.NASA’s Johnson Space Center innovators have designed a Robotic Inspection System that is capable of surveying deep sea structures such as oil platform storage cells/tanks and pipelines in order to determine the volume of material remaining inside, interrogate structure integrity, and display real-time video and sonar. This inspection device and method could significantly reduce the cost of inspecting, and in the future, provide sampling of the structure contents. The technology is an all-in-one inspection device that includes cameras, sonar, and motion-sensing instruments with hardware and software components. This NASA-developed technology is available for licensing.
