Wafer-Level Lens Alignment

Over one billion cell phones with cameras are sold every year, and this number has been increasing annually at a rate of about 15 percent for the past 7 years. Approximately 80 percent of cell phones now have embedded cameras, with about 20 percent of new cell phones having two cameras – one on the back for taking photographs and one on the front for videoconferencing.

Software Aids Design of Ares V Composite Shroud Structure

NASA’s Ares V space launch vehicle makes significant use of composites, and during flight, the shroud of the Ares V will separate into four petals to release the Lunar Lander. In the design of the structure, the aerodynamic pressure on the shroud is resolved into internally distributed forces. A combination of two software packages — HyperSizer structural sizing software and Abaqus FEA (finite element analysis) software from SIMULIA (Providence, RI) — was used to model and simulate this process.

Battery Will Provide Backup Power for Space Shuttles

International Battery is building a battery prototype for NASA that will provide backup power in support of the space shuttle program. NASA is interested in the company’s largeformat, high-energy-density prismatic cells that provide advanced energy storage, as well as their Battery Management System (BMS). The BMS is specifically designed for large-format cells and provides increased safety through individual cell monitoring and continuous cell balancing. The entire system is being deployed as an uninterruptible power supply (UPS) to maintain backup power for critical ground operations.

High-Speed Vision Inspection for Sheet-Based Electronics Materials

Process Photonics (Ottawa, ON, Canada) builds processing systems for the PCB, electronics assembly, and medical device markets. Their ProVisionTM series is a solution that uses vision to inspect panel and sheet-based circuit features. The system concept was devised after a customer expressed interest in replacing multiple existing inspection machines. The customer wanted a unit that was capable of significantly higher resolution and throughput, but also wanted to plan for a system that could perform defect recognition tasks beyond the original system’s capabilities.

Composites Software Helps in Design and Fabrication of Crew Module

FiberSIM® composites engineering software Vistagy Waltham, MA 781-250-6800 www.vistagy.comWhen NASA originally considered employing composites in manned spacecraft, it had to consider concerns that composites might have an unacceptable leak rate and insufficient damage tolerance. On the other hand, composites potentially offered reduced weight and lower lifecycle costs. The NASA Engineering and Safety Center (NESC) put together a team of government and industry structures experts to gain experience in making use of new composite construction and inspection technologies specifically for manned spaceflight structures.
