Lenslet Ltd., Herzelia Pituach, IS, a designer and developer of advanced optical digital signal processing engines (ODSPE), has been demonstrating EnLight, described as the first commercial optical digital signal processor. The device is specified to run at a speed of 8 Tera (8,000 Giga) operations per second, one thousand times faster than any known DSP. This product will benefit applications in the fields of defense, homeland security, multimedia and communications. The triple order of magnitude acceleration delivered by the EnLight platform opens the door to previously unfeasible defense capabilities as identified by various defense experts. “This quantum leap in computation performance, enabled by optical processing, opens the door to new capabilities in the battlefield of the future, creating strategic implications. This new development will revolutionize the nature of warfare with an effect similar to those caused by the appearance of the tank or the airplane,” said Major-General (Ret.) Isaac Ben-Israel, former head of the R&D Directorate of the Israeli Ministry of Defense. Some potential benefits include: enhanced communications in noisy channels; multi-channel interference cancellation; multi-protocol receiver (SDR), improved resolution and image for SAR radars; digital beam forming; enhanced signal detection in EW/RWR systems; and real time, multi-channel video compression and processing at high image resolutions (H.264 compression for multi HDTV channels). In the area of Homeland Security: improved throughput and detection accuracy for baggage scanning and multi sensor threat analysis. “Leading global companies have identified the previously inconceivable potential of Lenslet’s product and are examining innovative systems based on the EnLight platform,” says Aviram Sariel, CEO and Founder of Lenslet Ltd. This optical processor was developed over the past three years by researchers, scientists and engineers supported by a group of international professors from the realms of optics, physics and signal processing. The processor offers a combined solution of optics and silicon in the format of a standard electronic board card with standard interfaces and development tools as generally accepted in the industry.
Not a product for practical jokers to bring to the barbecue, CFOAM, developed by Touchstone Research Laboratory LTD, Tridelphia, WV, eventually may be used as a core material in a structural composite for making ships more fireproof, as a firewall in aircraft, and as energy absorbing structural components in automobiles. The material, made from coal under controlled conditions, feels like foam insulation, but is far stronger — one square inch of the material can support the weight of a full-size car without crushing. The flame of an acetylene torch impinging directly on the foam won’t initiate combustion. “The foaming takes all of
the volatiles out,” says Gerrill Griffith, spokesman for Touchstone. Properties of the foam can be manipulated to produce special results — for example, the density can be adjusted from 5 to 40 lb/ft3, with varying tensile strengths. CFOAM can also be graded in density and pore structure through its thickness to provide localized stiffness and thermal expansion control, while maintaining an overall weight-efficient structure. Heat-treating also varies the foam’s properties — with normal treatment, CFOAM is a thermal insulator and electrical conductor. Increasing the heat treatment temperature creates thermally conductive foam with higher electrical conductivity. The electrical property can be varied over several orders of magnitude. Another interesting property is the foam’s thermal expansion coefficient. “It has a very low coefficient of expansion,” says Griffith. “If you make a mold out of CFOAM and pour something hot into it, it won’t contract or expand like other materials.” Presently, a pilot plant is producing samples, but facility expansion is underway, which may eventually bring the cost of CFOAM into a range where it could even be used as a building material for homes.
