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.

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.

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.

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.

Samsung Electronics Co., Ltd., the world’s largest provider of thin-film transistor liquid crystal display (TFT-LCD) panels announced today that it has developed the world’s first “Blue Phase” LCD panel – which will offer more natural moving images with an unprecedented image-driving speed of 240 Hertz. Samsung is planning to unveil a 15” model of its Blue Phase LCD panel at the SID (Society for Information Display) 2008 international Symposium, Seminar and Exhibition, which will be held in Los Angeles from May 18 to 23.

Executive Vice President Souk Jun-hyung, the head of LCD Business’ Display R&D Center, said that “Our Blue Phase mode is a major evolutionary development beyond conventional liquid crystal modes. Samsung’s development of the technology provides a tremendous opportunity to move image quality of LCD screens much closer to that of a real moving image.”

Gnat-sized robots, microscopic gyroscopes, television beamed directly onto your retina. This may sound like a grocery list for a crazed sci-fi visionary. But all these projects are in the works today, thanks to an emerging chip technology known as microelectromechanical systems. While magical microbots may still be a few years away, MEMS are already a multibillion-dollar business in the car, printer, and display-projection industries.

Traditional chips are flat, static structures. MEMS, by contrast, are silicon wafers packed with kinetic, three-dimensional gizmos: laboratories, laser-guided mirrors, canals flowing with chemicals. An offshoot of the semiconductor industry, MEMS benefit from the well-known peculiarities of the silicon universe - every year chips get tinier, cheaper, and faster.

This undated handout photo provided by IBM and the Feature Photo Service shows lead engineer Don Grice of IBM inspecting the world’s fastest computer, nicknamed “Roadrunner”, in the company’s Poughkeepsie, N.Y. plant. Scientists unveiled the world’s fastest supercomputer on Monday, June 9, 2008, a $100 million machine that for the first time has performed 1,000 trillion calculations per second in a sustained exercise. The technology breakthrough was accomplished by engineers from the Los Alamos National Laboratory and the IBM Corp. on a computer to be used primarily on nuclear weapons work, including simulating nuclear explosions.

Antennas serve as transducers between electromagnetic waves traveling in free space and guided electromagnetic signals in circuits. As such, they play a critical role in the performance of wireless communication systems. With the proliferation of mobile wireless services that deliver voice and/or data in smaller and smaller devices, the task to design an antenna for a portable unit that meets not only operational requirements but also aesthetic and packaging restrictions is becoming more and more challenging. As result, engineers rely on a combination of theory, simulation, and experimental investigation to arrive at a design that meets all the demands of a particular application.

Basic Antenna Parameters

The basic parameters of antenna are impedence, mismatch and ohmic efficiency, radiation pattern and polarization, directivity, gain and equivalent isotropically radiated power, and effective height and aperture. In addition, celebrated Friis equation is and equations for the signal to noise ratio (SNR) of an antenna and source-field relationships are also important.For a more detailed treatment of the material pointed out here, the reader is referred to “A HANDBOOK OF ANTENNA IN WIRELESS COMMUNICATION” OF CRC Press by Lal Chand Godara.

The U.S. Air Force Research Laboratory has authorized Raytheon Company to demonstrate target recognition technology designed to increase protection for ground forces without compounding risk to an aircraft stalking enemies who threaten those forces.

First in a laboratory and then aloft, the company expects to show how its Air-to-Ground Radar Imaging II program would permit aircraft at a safe distance to detect, track and target hostile forces in motion on the ground.

The laboratory demonstration is expected in autumn 2008, followed by a flight next spring aboard a Raytheon test aircraft.
