Soft-Tissue Emulsification Using a Mechanism of Ultrasonic Atomization Inside Gas or Vapor Cavities

Lyndon B. Johnson Space Center, Houston, Texas The current method of emulsifying tissue employs focused ultrasound with microsecond pulses and cavitation. This invention emulsifies soft tissue using a mechanism of ultrasonic atomization inside gas or vapor cavities. The method of non-invasively treating tissue includes pulsing ultrasound energy from the ultrasound source toward the target site in the tissue. The ultrasound source is configured to emit high-intensity focused ultrasound (HIFU) waves. The target site comprises a pressure-release interface of a gas or vapor cavity located within the tissue. The method continues by generating shock waves in the tissue to induce a lesion at the target site. It additionally includes characterizing the lesion based on a degree of at least one of a mechanical or thermal ablation of the tissue. This work was done by Oleg Sapozhnikov, Michael Bailey, Tatiana Khokholova, Vera Khokholova, and Julianna Simon of the University of Washington for Johnson Space Center. NASA is seeking partners to further develop this technology through joint cooperative research and development.

System and Method for Transferring Telemetry Data Between a Ground Station and a Control Center

Goddard Space Flight Center, Greenbelt, Maryland The Lunar Reconnaissance Orbiter (LRO) employs many advanced innovations developed at NASA’s Goddard Space Flight Center and in collaboration with other organizations. The applications and benefits for these technologies are advantageous for many other industries as well. One of those technologies is the Space Link Extension Return Channel Frames (SLE-RCF) software library. This software library enables a mission control center to receive telemetry frames from a ground station. The technology implements the SLE-RCF protocol as defined by the Consultative Committee for Space Data Systems (CCSDS). Software routines can be reused from mission to mission.

Method and Apparatus for Generating Flight-Optimizing Trajectories

Flight path and altitude modifications are pre-cleared of potential conflicts with other known airplane traffic, weather hazards, and airspace restrictions. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center is developing Traffic Aware Strategic Aircrew Requests (TASAR). TASAR features a cockpit automation system that monitors for potential flight trajectory improvements and displays them to the pilot. These wind-optimized flight trajectory changes are pre-cleared of potential conflicts with other known airplane traffic, weather hazards, and airspace restrictions. The TASAR is to improve the process in which pilots request flight path and altitude modifications due to changing flight conditions. Changes may be made to reduce flight time, increase fuel efficiency, or improve some other flight attribute desired by the operator. Currently, pilots make such requests to air traffic control (ATC) with limited awareness of what is happening around them. Consequently, some of these requests will be denied resulting in no flight improvements and an unnecessary workload increase for both pilots and ATC. The TASAR technology provides pilots with recommended flight path and altitude improvements that are more likely to be approved by ATC.

The K Development Language

NASA’s Jet Propulsion Laboratory, Pasadena, California Graphical modeling tools have gained popularity within engineering communities, but such languages are known to suffer from lack of semantics and mathematical rigor. By supporting a graphical language with a textual language, and mapping graphical models to the textual language, one ensures proper unique semantics of the graphical language. In addition, some engineers prefer to express themselves in textual languages not unlike programming languages. This is in part due to the fact that it can be unnecessarily time-consuming to model graphically, and graphical models take up a considerable amount of visual space. As an example, the definition of a function in K may occupy one line of text, whereas in a graphical modeling language, it is not uncommon that such a specification may occupy one page. Finally, it is easier to provide analytical support for a textual language.

Mission Assurance Systems (MAS) Software Used for Engineering Data Sets Across NASA

Ames Research Center, Moffett Field, California In the 2006 timeframe NASA’s Constellation Program was looking to address several issues with the way Problem Reporting data had been collected for the Shuttle Program including multiple systems across groups and centers (20+ for Shuttle), inconsistent schemas and processes across systems, difficulty searching within each system, and lack of ability to search across systems. The Program’s goal was to deploy a single new system to be used across the participating groups and centers. The Ames Human-Computer Interaction (HCI) group conducted requirements research into problem reporting across NASA missions (Shuttle, ISS, Mars Exploration Rovers, etc.), centers (JSC, KSC, MSFC, Langley, Armstrong, etc.), and external groups (e.g., the Navy’s SubSafe Program).
