Handling Delicate Materials

Special care needs to be taken when handling delicate materials used in medical applications. Small diameters provide increased flexibility needed for long-flex-life applications such as cardiac catheter wires. Many other applications also use these fine materials as winding and braiding materials, including the medical device industry, microelectronics, and composites.

The Benefits of Modern CMOS Sensors in Industrial Line Scan Cameras

As sensor technology has improv ed in leaps and bounds, the old rule of thumb familiar to many line scan camera users has lost much of its punch. The idea that CCD equals high image quality while CMOS equals speed is only true under very limited circumstances. While charge-coupled device (CCD) and complementary metal-oxidesemiconductor (CMOS) sensors perform similar functions — collecting light (photons) and converting those into charges (electrons) — there are a few fundamental differences between their methods. The biggest difference is in the sensor architecture. While CCD sensors generally employ a majority of the pixel surface for capturing light, CMOS sensors use a portion of that surface for conversion electronics.

Anti-Icing Formulas Prevent Train Delays

A formula designed for military aircraft keeps trains on the rails. In the winter of 2009, Washington, DC workers faced the prospect of a difficult commute due to record-setting snowfall. But thousands of the city’s Metrorail riders found the public transportation system fully functional, thanks in part to a NASA technology invented years before.

Curiosity: One Year Later

On August 5, 2012, the Mars Science Laboratory (MSL) rover, Curiosity, landed in Gale Crater in a perfectly executed procedure originally referred to as “7 Minutes of Terror.” A year into its two-year exploration of the Red Planet, Curiosity has already achieved the major goal of its mission. Last year, NASA Tech Briefs spoke with members of the MSL team just two weeks before the historic landing about what NASA hoped to find, the technologies used onboard Curiosity, and how the mission was expected to progress. Here, we revisit MSL team members and program executives to get updates on the current state of the mission.

Mars 2020: The Next Journey

Building on the success of Curiosity’s landing, NASA has announced plans for the next robotic science rover, which is set to launch in 2020. The proposed 2020 rover mission is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the red planet. The mission would address key questions about the potential for life on Mars, and would provide opportunities to gather knowledge and demonstrate technologies that address the challenges of future human expeditions to Mars.

CAMERA TRENDS 2013: A Simpler Machine Vision

Today’s cameras are cheaper, smaller, and more capable than ever before. Without breaking the budget, a company manager who needs products inspected can buy a camera, quickly code in commands to recognize an object, bracket the device above a production line, and begin capturing images.
