Researchers And Students To Develop Small CubeSat Satellites, the Size of a Loaf of Bread

A CubeSat is a type of space research picosatellite with dimensions usually of 10×10×10 centimetres (i.e., a volume of exactly one litre), weighing no more than one kilogram, and typically using commercial off-the-shelf electronics components.

Developed through joint efforts, California Polytechnic State University and Stanford University introduced the CubeSat to academia as a way for universities throughout the world to enter the realm of space science and exploration.

Currently, a large number of universities and some companies and other organizations around the world are actively developing CubeSats. One of these companies Clyde-Space, has just developed an ‘off-the-shelf’ website with information and resources for various sized cubesats and their subsystems. Other suppliers such as ISIS and GomSpace are also offering products and services through their websites.
With their relatively small size, CubeSats can be made and launched for an estimated US$65,000–80,000 each (2004 US dollars). This low price tag, as compared to most satellite launches, has made Cubesat a viable option for schools and universities across the world.

Test And Measurement Industry Trends Toward Software-Defined Instrumentation

Test engineers in industries ranging from aerospace and defense to consumer electronics are facing the challenge of testing increasingly complicated designs with shrinking timelines and budgets. To address these issues, engineers and scientists are incorporating new test and measurement technologies that are capable of meeting complex design requirements without raising costs. National Instruments (NI) has identified five trends it anticipates will significantly influence the test and measurement industry over the next three years.”Companies are turning to the latest technologies including PXI, FPGAs and multicore processors to develop high-performance test systems that can meet consumer demand for higher-quality products,” said Eric Starkloff, National Instruments director of test product marketing.

HGH Infrared Systems Introduces A 3 Million Pixel, 20-Degree FOV, IR Panoramic Camera

HGH Infrared Systems, manufacturers of advanced infrared cameras and a variety of thermal imaging products and systems, introduced the new IR Revolution 360, a 20° vertical, 360° horizontal field of view (FOV) panoramic infrared vision system for security and surveillance.

HGH Infrared Systems Introduces A 3 Million Pixel, 20-Degree FOV, IR Panoramic Camera The revolutionary sensor contains approx. 3 million pixels (10,000 x 288). This advanced thermal imager delivers clear, extremely high resolution imagery via the rotating head that scans a full 360-degree rotation per second. Other features include auto detection and tracking, a motion alarm, and an area-of-interest zoom.

The detector is based on mercury cadmium telluride (HgCdTe) imaging technology and operates in the 8 -12 micron wavelength, the long-wave infrared (LWIR) region. The high sensitivity (<25 mK) IR camera detection range, without image distortion, is up to 1 kilometer (km) for a human figure, up to 1.5 km for an automobile, and up to 6 km for a boat or ship.

ODA-6W-500M: Photodetector-Preamplifier

The new NIR / Red Enhanced 6mm² ODA-6W-500M Photodetector-Preamplifier from Opto Diode Corporation is a photodiode preamplifier combination device that features higher gain in lower light environments. The low light, high sensitivity component has a large active area that operates in the NIR wavelength with response at 940 nm (typically 315 V/µW, min. 290). The standard 6mm² ODA-6W-500M offers 500 Mohm gain with custom gains also available, per customer specifications. Opto Diode’s new component is based on their proprietary shielded amplifier electronics, featuring extremely low noise and high sensitivity in the red enhanced preamp combination detector.

Smaller and more compact than discrete solutions, the hermetically-sealed TO-39 can is highly suitable for assembly in confined spaces. Ideal for applications such as fluorescence, microscopy and analytical chemistry, the detector is designed for easy integration into new and existing systems. Storage and operating temperature ranges from -25 degrees C to +100 degrees C.

Robotic Transporters for Large Weldments

Robotic transporters are key when you want to automate welding of extremely large, heavy parts.  The maximum work envelope radius of an extended-reach robot is about 3-meters (9.84’).  If the parts you are welding require more reach than that, you need to find ways to move the robot to the part to provide optimal torch access to the welds.  A variety of robot transporters are available, and each type lends itself to a particular type of work flow.  How do you decide whether your application is best-suited for a linear floor- or wall-mounted track, linear overhead gantry or radial transport beam solution?

Fly-by-Wireless: A Less-Wire and Wireless Revolution for Aerospace Vehicle Architectures

Fly-by-Wireless

Every ounce of weight brought to the lunar surface costs 40 to 60 times that in fuel needed at liftoff from the Earth. Part of that weight penalty is due to wires, but the cost of wires is much more than weight. Wired connectivity drives up the price of design from the beginning: it drives the cost of the many systems and structures; it drives inspection, troubleshooting, maintenance, and upgrade costs; as well as the cost of making system changes. Future vehicles that can reduce the effects and limitations of wires will not be without risk or a lot of work, but the effort has begun.
