Three Strategies for Building Efficient Test Systems

Test engineers are facing new pressures to develop high-performance test systems that maximize efficiency. Despite rapidly increasing device complexity, they have to deliver higher-speed and lower-cost test systems, as well as contribute to corporate sustainability programs. This pressure is exemplified by the addition of corporate responsibility and sustainability programs presented on almost every corporate Web site. These corporate sustainability programs often have goals of reducing energy consumption, carbon footprints, and emissions.

NASA Probes Gather Solar Information

STEREO observatories and Solar Probe Johns Hopkins University Applied Physics Laboratory Laurel, MD 240-228-5000 www.jhuapl.edu

NASA’s Solar Terrestrial Relations Observatory (STEREO) is comprised of two nearly identical spacecraft that were launched in 2006. They will gather images of the Sun simultaneously from different angles. These images will then be combined to produce three-dimensional pictures of coronal mass ejections. These eruptions can blow 10 billion tons of the Sun’s atmosphere into space, and can trigger severe magnetic storms on Earth that cut off electric power and communications.

Spacecraft Leak Detection System Uses Ultrasonic Sensors

Spacecraft leak detection system Invocon Conroe, TX 281-292-9903 www.invocon.com

NASA has selected a spacecraft leak detection system from Invocon that would sense and locate air leaks in pressurized space stations or lunar habitat modules caused by micrometeoroid and space debris impact events. Low-cost, ultrasonic sensor arrays developed by Iowa State University are used in the system. The spacecraft structure would be monitored for leak-generated, surface- borne ultrasound by means of a flexible and modular electronics package with fully integrated data sensors, data acquisiti

iMonitor 2.0

Aegis Software, Horsham, PA, has introduced iMonitor 2.0 software that enables manufacturers to create real-time dashboards to monitor their enterprise, factory, and processes through Web browsers. It provides interactive production tracking, materials, utilization, alarm, line condition, tooling life, and quality dashboards, which are constructed by dragging and dropping gauges, charts, and other elements into a design view, along with user-provided graphics such as line pictures or plant drawings. The software operates like a Web site — users link gauges or charts in one dashboard to another, creating a dashboard site structure. Users can create unlimited numbers of dashboards and store them for viewing on the Web.

NASA Nano Sensor Helps Detect Biohazards

A nanotechnology-based biosensor developed by NASA’s Ames Research Center in Moffett Field, CA, detects trace amounts of bacteria, viruses, and parasites. The sensor has been licensed to Early Warning Inc. of Troy, NY, which will use the sensor to prevent the spread of potentially deadly biohazards in water, food, and other sources.

Hand-Held Ultrasonic Instrument for Reading Matrix Symbols

All necessary functions would be performed within a compact package.

A hand-held instrument that would include an ultrasonic camera has been proposed as an efficient means of reading matrix symbols. The proposed instrument could be operated without mechanical raster scanning. All electronic functions from excitation of ultrasonic pulses through final digital processing for decoding matrix symbols would be performed by dedicated circuitry within the single, compact instrument housing.
