Emhart Teknologies Presents “Create the Future” 2006 Design Contest Winners

Creating the future is about change, creativity, and risk - the core building blocks that foster innovation. For the past five years, Emhart Teknologies has partnered with NASA Tech Briefs in challenging the engineering community through our “Create the Future” Design Contest. The worldwide engineering community’s response to the challenge surpassed our expectations once again. To encourage and recognize outstanding innovation in product design, the “Create the Future” design contest seeks to foster innovation in the categories of everyday products, safety, transportation, and medical. These categories were selected because they are areas where innovation can significantly improve the quality of our lives at home, work, recreation, or when we travel. Submitting an entry to the contest required commitment and attention to detail. Our panel of expert judges carefully scrutinized drawings, written descriptions, and all information that was relevant to the idea.

Innovation in 3D PDF

Michael KaplanBy Michael Kaplan Director of Engineering Adobe Acrobat Adobe Systems Inc. San Jose, CA When I started graduate studies in 3D computer graphics in 1978, dinosaurs roamed the Earth. I still remember my shock the first time I saw a real-time 3D vector graphics system. That quick glimpse of the future changed my life. The next day I applied to the Masters Program at the Cornell Program of Computer Graphics, and I’ve been working full-time on real-time 3D graphics ever since.

Laser Scanning System Helps Validate Method for Repairing Space Shuttle Heat Shield

SLP-330 Laser Scanning Probe Laser Design Minneapolis, MN 952-884-9648 www.laserdesign.com The loss of the Space Shuttle Columbia because of damage to its thermal protection system (TPS) during launch spurred a search for methods of repairing the TPS in space; specifically, repairing the Reinforced Carbon-Carbon (RCC) material used to protect the nose cap and wing leading edge panels that experience the most extreme heating — more than 3,000° F — during the return to Earth. In testing possible repair methods, it is critical to accurately measure the complex freeform 3D RCC panel shape after the damage, after the repair, and after tests that simulate re-entry. NASA used the SLP-330 laser scanning probe from Laser Design, integrated with Romer portable coordinate measuring machine (CMM) arms for this task.

Desktop 3D Scanner

NextEngine, Santa Monica, CA, offers the Desktop 3D Scanner, a full-color multi-laser scanner that scans complex shapes for CAD and 3D design applications on the desktop. About the size of a cereal box, the scanner connects directly to a PC via USB 2.0. It operates with proprietary MultiStripe Laser Triangulation (MLT) technology that features twin arrays of four Class 1M 10-mW solid-state lasers with custom optics at a 650-nm wavelength. The scanner also features twin 3-megapixel CMOS RGB image sensors, optically synchronous RGB color texture capture, and built-in spatially diverse white-light texture illuminators. Full-color photo data is captured for each surface point, and there is no preset limit for the size of objects to be scanned. Objects larger than 5.1 x 3.8" in macro mode and 13.5 x 10.1" in wide mode can be composite-captured with supplied ScanStudio(tm) software. The unit has throughput of 50,000 processed points per second, and comes with an AutoPositioner(tm) to capture multiple surfaces of objects, and a PartGripper(tm) to secure objects during scanning.

Dr. Karen Jackson, Aerospace Engineer, Landing and Impact Research (LandIR) Facility

NASA Langley Research Center, Hampton, VA Dr. Karen JacksonIn a crash, keeping the occupants alive and uninjured is paramount. In order to study the dynamics of an impact, military and general aviation aircraft, like cars, must be tested for their ability to keep their riders safe. A part of Structural Dynamics Branch in the Research and Technology Directorate at NASA Langley, the Landing and Impact Research Facility (LandIR) tests aircraft by crashing them. Dr. Karen Jackson is part of the research team.

On-Chip Debugging Emulator (Renesas Technology America)

Renesas Technology America, Inc. (San Jose, CA) offers the E8a emulator, an onchip debugging emulator for developing embedded systems that use Renesas microcontrollers. It allows referencing and modification of memory, on-chip I/O, and memory contents while a program is being executed. The tool allows C source-level debugging to be carried out with a microcontroller in the M16C, H8/Tiny, or H8/Super Low Power series, operating at full speed in the system. The device also can be used as a programmer to load code into the internal flash memory of many Renesas microcontroller families. The programming voltage range is 1.8 to 5 V, and the unit features a clock oscillator to enable asynchronous communication in line with a microcontroller’s operating frequency. The case measures 92 × 42 × 15 mm.
