NASA's Hot 100 Technologies: Health, Medicine & Biotechnology

Atomic Oxygen Texturing and Cleaning Atomic oxygen oxidizes and removes biologically active contaminants, and reduces the contaminant to an inactive ash. Thus, the contaminant is both sterile and biologically inactive. The resulting surface is entirely free of any bacteria, viruses, prions, cells, or any organic matter. Currently, 3/4 of orthopedic implants have measurable amounts of endotoxins. Atomic oxygen could totally eliminate these endotoxins, greatly reducing chances of post-operative inflammation.

NASA's Hot 100 Technologies: Information Technology & Software

Enhanced Project Management Tool This invention is a system for managing a project that includes multiple tasks and workers. Periodic monthly, task plan, schedule, and budget reports are generated and made available for display or further analysis. When the system receives a description of a skill set needed for a project, the skill set module is queried. The name and relevant skill(s) possessed by each worker is displayed in a visually perceptible format.

NASA's Hot 100 Technologies: Instrumentation

Powder Handling Device for Analytical Instruments This technology provides automated sample handling and movement of coarse-grained powder or other solid materials to enable analysis by a robotic or totally automated computer system. The powder is handled as a fluid, using mechanical vibrations in conjunction with a driving force, and requiring few or no moving parts.

NASA's Hot 100 Technologies: Manufacturing & Prototyping

Variable Power Handheld Laser Torch A handheld laser torch was designed for welding and brazing metals to repair hard-to-reach space shuttle engine nozzles. It incorporates various manual controls and changing lenses to allow the operator to adjust the laser’s power output in real time. Applications are likely to be in-field welding and brazing of damaged equipment where traditional welding systems cannot easily access the welding area.

Shape Memory Alloys Shape Memory Alloys (SMAs) can be deformed at low temperature and recover their original shape upon heating. New alloys can operate up to ~300 °C, compared to ~80 °C for commercially available alloys. SMAs can be used in adaptive structures, actuators, heat detection devices, medical devices, high-temperature automotive components, aeronautics, and military.

Spring Joint Package with Overstrain Sensor This flexible joint provides two degrees of freedom and a tremendous amount of compliance. The overstrain sensor joint has a passive and restoring force that allows the joint to return to a default position, and is also proportional to the amount of lateral deflection the spring has undergone; this allows the OS sensor joint to be used in many of the under-constrained situations that cause universal joints to lock up.

NASA's Hot 100 Technologies: Optics

Automated Vision Test The traditional test for visual acuity requires the patient to look and report which letters they see. A new invention provides an automated system to estimate visual acuity based on objective measurements of the eye optics and wavefront aberrations. A typical measurement consists of a list of numbers that constitute the coefficients of the polynomials. The algorithm converts the list of numbers into an estimate of the visual acuity of the patient.
