Starr Ginn, Deputy Branch Chief, Engineering Directorate, Aerostructures Branch, Dryden Flight Research Center

Starr Ginn decided she wanted to work for NASA after interning in their Summer High School Apprenticeship Research Program (SHARP) following her junior year in high school. She is currently the Deputy Branch Chief of the engineering directorate’s aerostructures branch at the Dryden Flight Research Center. An expert in aircraft ground vibration testing and flight flutter testing, she recently designed and developed a unique aircraft jacking system that allows a test specimen to “float” during ground vibration testing.

Ruggedized Micro Spectrometer Module

Mutoh America Inc. Developed originally for color-matching inks on digital printers, Mutoh’s spectrometer modules offer a plug-in solution that carries its own ADC, MCU, and memory onboard. These devices employ an optical system different from most other spectrometers sold today: Mutoh’s patent-pending DP1 “digital prism” spectral sensor. This sensor replaces the traditional slit/grating/imager design with a single spectral imaging chip in a 1 × 9-mm footprint. Current designs can deliver 3-nanometer resolution with >4000:1 dynamic range and low signal-to-noise ratio. Deconvolution of the raw sensor data is handled by the integrated logic, delivering calibrated spectral data without the need for a back-end processor. These modules are rugged, highly customizable, low-cost even in small volumes, and offer a high degree of design versatility.

Super Bulk Production of Single-Walled Carbon Nanotubes

Japan Industrial Technology Association Highly pure, single-walled carbon nanotubes (SWNTs) are mass-produced in bulk forms such as vertically aligned “forests” through a process called Super CVD, a supercharged chemical vapor deposition (CVD) process. Structures of carbon SWNT are patterned and their growth controlled using specialized methods and furnaces.

Low-Friction Surface for Ready-to-Use Catheter

A company seeks a low-friction surface for ready-to-use intermittent catheters for both men and women, with the goal of achieving insertion and retraction without causing any trauma or perception of trauma. The low-friction surface must operate during insertion, while the catheter is in place, and during removal. Balance between kink-resistance and flexibility is important, and the ability to insert the catheter without touching it would be ideal. It must offer 3-5 years of shelf life at ambient temperatures, and use biocompatible materlals.

One-Handed Ergonomic Approach to Pliers/Cutters

A company seeks a new generation of precise, ergonomic pliers that virtually eliminates the effort that causes hand fatigue. Ideally, it would require the exertion of zero force to cut through Romex, strapping, or staples. The tool must provide one-handed operation and conform to a variety of grips a worker may use. It is preferable that the device use mechanical advantage rather than power, although self-contained power assist is acceptable. A battery pack or compressed air connection will not work.

Greg Olsen on Imaging, Space Science, and the Future of Engineering

Dr. Greg Olsen has had an illustrious career as a research scientist and entrepreneur. With degrees in physics and materials science, Olsen founded EPITAXX, a fiber-optic detector manufacturer, in 1984, and then founded Sensors Unlimited Inc. (SUI), a near-infrared camera manufacturer in 1992. SUI was sold to Goodrich Corp. in 2005. During his career, Olsen developed vapor phase epitaxial crystal growth of optoelectronic devices, including laser diodes and photodetectors for fiber-optic applications based on the material indium gallium arsenide (InGaAs). He was awarded 12 patents, wrote more than 100 technical papers, co-authored several book chapters, and has given numerous lectures to both technical and trade journal audiences.
