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 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.

“Fortunately, more technology vendors are developing industry-standard tools capable of solving problems that previously depended on expensive, dedicated test systems.”

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.

Researchers at Northwestern University and Princeton University have created a new kind of polymer that, because of its extraordinary thermal and mechanical properties, could be used in everything from airplanes to solar cells.

The polymer, a nanocomposite that incorporates functionalized, exfoliated graphene sheets, even conducts electricity, and researchers hope to use that property to eventually create thermally stable, optically transparent conducting polymers.

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.”

Human-implantable RFID microchips face an uncertain future in the wake of developments that the technology’s developer, VeriChip, announced last week. The Delray Beach, Florida-based company announced it sold most of its assets to tool manufacturer Stanley Works for $45 million and that the rest of the company is for sale (see VeriChip Sells an RFID Business, More Change May Come). The remaining company essentially consists of the VeriMed Health Link business line, a patient identification service based on VeriChip’s controversial, FDA-approved line of implantable RFID tags for lifetime human identification.

“That business is not self-sustainable,” VeriChip vice president of corporate development Jay McKeage candidly told RFID Update. “It cannot stand on its own because of the cash burn involved in marketing to consumers.”

VeriMed Health Link is a service in which patients have an RFID tag injected under their skin in the arm to provide lifetime identification. The tag is encoded with a 16-digit unique ID number, which medical professionals with VeriChip-issued readers can use to access the patient’s complete medical history from a secure database. VeriChip markets the system on patient-safety benefits — emergency room doctors or other medical staff can access a patient’s medical history without relying on a patient response or an ID card. The idea is that even if a patient arrives unconscious or otherwise uncommunicative, his or her complete medical history is still accessible. The FDA approved VeriChip’s human-implantable passive RFID microchips in 2004, but adoption has been limited.

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.

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.

Stanford chemists have developed a new way to make transistors out of carbon nanoribbons. The devices could someday be integrated into high-performance computer chips to increase their speed and generate less heat, which can damage today’s silicon-based chips when transistors are packed together tightly.
