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.

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.

White organic light-emitting diodes offer a power efficiency, lifetime, and brightness that together constitute a significant advance toward viable devices for lighting.

Light-emitting diodes (LEDs) are used in both displays and illumination applications because they are small, robust, and potentially very efficient. Organic light-emitting diodes (OLEDs) continue to gain attention from the scientific and industrial community. In contrast to their inorganic counterpart, OLEDs are flat and diffuse area light sources with the device thickness being in the range of 1–2mm. Thus far, OLED development has been triggered mainly by applications in the display segment, starting with applications for MP3 music players, mobile phones, and other portable devices. Recently, Sony brought to market the first OLED TV, which indicates that a more general penetration of the display market is close at hand.

OLEDs have not yet entered the lighting market, but that will probably change soon. Already most of the big players in the field are preparing for OLEDs to become ‘the next big thing.’ However, several critical problems need to be solved before widespread use for lighting becomes feasible. Specifically, the lifetimes, power efficiencies, reliability, and cost-effectiveness of white OLEDs must be able to compete with existing lighting technologies.

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.

Normally fragile and brittle silicon chips have been made to bend and fold, paving the way for a new generation of flexible electronic devices. The stretchy circuits could be used to build advanced brain implants, health monitors or smart clothing.

The complex devices consist of concertina-like folds of ultra-thin silicon bonded to sheets of rubber.

Writing in the journal Science, the US researchers say the chip’s performance is similar to conventional electronics. Continue reading ‘Silicon chips stretch into shape’ »

WEST LAFAYETTE, Ind. -

Engineers have created the first “active matrix” display using a new class of transparent transistors and circuits, a step toward realizing applications such as e-paper, flexible color monitors and “heads-up” displays in car windshields.

The transistors are made of “nanowires,” tiny cylindrical structures that are assembled on glass or thin films of flexible plastic. The researchers used nanowires as small as 20 nanometers - a thousand times thinner than a human hair - to create a display containing organic light emitting diodes, or OLEDS. The OLEDS are devices that rival the brightness of conventional pixels in flat-panel television sets, computer monitors and displays in consumer electronics.

Your work is in microelectromechanical systems (MEMS). Could you explain what this field is?

The name MEMS didn’t even exist in the ‘80s while I was in graduate school. My major was integrated circuits (IC) then. I learned solid-state devices and IC technology. So I know how to make these devices. It all started with an interesting question. We knew that the IC industry was really big in the 1980s. People had already invested billions, if not trillions, of dollars in IC technology. The question was: can we do something with the IC technology for applications other than IC? In other words, IC technology is a huge investment, could something else benefit from it? Here, IC is really only electrical devices. What devices, other than electrical devices, could we build? From an academic point of view, this whole world is either electrical or mechanical. For example, even biology and its fundamental science are all electrical or mechanical. Similarly, chemistry is no different.
