Data Acquisition System Monitors Lightning Strikes

Genesis HighSpeed data acquisition system and Perception software HBM Marlboro, MA 508-624-4500

NASA Kennedy Space Center, based in Cape Canaveral, FL, has one of the highest rates of ground lightning strikes per square kilometer in the United States. In 2009, it was estimated that the NASA Space Shuttle Endeavour launch pad area was struck a minimum of 11 times on the lightning mast and water tower, leading to costly launch delays. A spacecraft is vulnerable to lightning strike damage from the moment it emerges from the Vehicle Assembly Building (VAB) until final launch. During this time, it is important to continuously monitor numerous points to identify any potential induced area lightning effects.

LED Street Lights Cut Energy Consumption and Eliminate Bulb Changes

Dialight, Farmingdale, NJ

Founded over 200 years ago along the Mississippi River in Missouri, the city of Cape Girardeau is now home to almost 38,000 residents. The Missouri Highway 74 corridor through the city's downtown is one of the busiest thoroughfares in the city, leading up to the Emerson Memorial Bridge across the Mississippi and connecting Cape Girardeau with Illinois. Along this stretch of road, as well as North Kings highway, 250-W high-pressure sodium (HPS) street lights kept maintenance crews busy with frequent bulb changes.

Flexible LED Assembly for Automotive Signal Lighting

Philips Lumileds, San Jose, CA

A build-out-of-the-box approach to turn, tail, and stop lighting applications on vehicles significantly reduces engineering and development costs. With recent improvements to Snap LED, an automotive LED assembly, the need for retesting and screening is removed, which can save users on operational costs, reduce equipment and manpower needs, speed production, and improve finished goods yields. The LED assemblies can be shaped to any contour, allowing users to create more innovative and streamlined designs. SnapLED's solder-less clinch fastening technology is a formable metal substrate designed for ease of design and installation.

Fine Laser Cutting Technology

Fine laser cutting is an ideal technology for specialized cutting requirements found in the manufacturing of medical tube tools and components. From surgical instruments used in cutting and biopsy, to needles containing unusual tips and side wall openings, to puzzle chain linkages for flexible endoscopes, laser cutting provides higher precision, quality, and speed than traditionally used cutting techniques. In addition, new laser cutting technologies are now coming to market, including a 5-axis motion package that gives the designer freedom to cut more challenging geometries in one pass.

Multi-Layer Films and Tapes Provide Thermal Protection for NASA Spacecraft

Multi-Layer Insulation (MLI) materials Dunmore Corporation Bristol, PA 215-781-8895

The final flight of the Space Shuttle Atlantis carried Multi-Layer Insulation (MLI) materials from Dunmore Corp. The MLI materials replace heavier materials such as metals and composites used to shield sensitive space-based systems from cold, debris, and radiation. The cargo bays on Atlantis, as well as the Endeavor and Discovery shuttles, are lined with insulation blankets covered by Dunmore’s thermal protection systems (TPS). The insulation blankets protect the inside of the shuttle from extreme temperature fluctuations when the cargo bay doors are open.

DC Motor Automates Patient Transfer Device

One of the growing problems facing nurses is a reduced staff, and with it the need to care for overweight patients with very little help. This effort has led to musculoskeletal disorders (MSDs) including back injuries. In fact, 12 percent of nurses leave the profession each year due to back injuries. Those working in nursing homes have an even higher rate of injuries. Until recently, moving a patient was performed manually or with minimal automation.

Capacitive Pressure Sensor Enables Better Combustor Design

Pressure sensor Sporian® Microsystems Lafayette, CO 303-516-9116

Sporian Microsystems has been awarded a NASA contract to develop a capacitive pressure sensor. The sensor must survive extremely harsh conditions, including temperatures in excess of 1000 °C (1832 °F), pressures in excess of 500 PSI (34 bars), as well as exposure to corrosive and oxidizing gasses.
