   "Antipersonnel mines can have many shapes," said Dimitri M. Donskoy, an associate professor at Stevens Institute of Technology in Hoboken, N.J., who has developed one of the new mine detection systems. "But they all have this flexible casing and they all vibrate differently than the objects around them." The waves are strong enough to vibrate the mines but will not set them off, said Dr. Donskoy, who has tested some of his equipment with live mines.
   
   Much of the research in the new technology is financed by the Army and the Navy.

   Dr. Donskoy said that the resonant response of mines was complex, and depended upon the interaction between the soil and mines and their respective properties. For example, in a desert, his prediction model might suggest a frequency range of vibration of 50 to 75 cycles per second, or hertz, because of the sandy soil. "Whereas when you move into another area with a rainy season," he said, "you might start at 100 to 150 hertz to detect the mine."

   Donskoy, associate professor of civil, environmental and ocean engineering at Stevens, has been developing a unique landmine detection technology for commercialization.
   
   The June tests were conducted at a U.S. Army outdoor range in Virginia. Donskoy and his team used hypersensitive acoustical landmine detection equipment developed at Stevens.
   
   Moving slowly through the testing range, the team sent out nonlinear acoustical wave patterns specially programmed to detect "canister-style" landmines. These are the most common types of mines found in danger zones throughout the world, and are manufactured in numerous varieties as both anti-tank and anti-personnel explosives. Donskoy's system uses a computer database that contains the structural "profiles" of some 50 types of mines.
   ...
   Working with the U.S. Army and Landmine Detection Systems, Inc., Donskoy's team is taking the next practical step. A smaller, robust, and affordable acoustical detector is now in the testing stages. Given recent validations of the technology, the resulting prototype should be a model for the international mine removal operations of the future. - PB
   
   Update: Anti-termite technology funded
   
   Recently, Dr. Dimitri Donskoy received a $250,000 Springboard Fund recoverable grant from the New Jersey Commission on Science and Technology (NJCST). The check was presented this fall to Donskoy and Intelligent Sensing Technologies (IST), a Stevens-incubated company that will develop pre-production prototypes for Donskoy's Total Wood Inspection system (TWiN). The technology is a breakthrough, non-destructive application for detecting active and non-active infestations by wood-destroying insects, such as termites and carpenter ants. The TWiN system involves a magnetic wave sensor able to detect both voids in wood and insect movements. Donskoy and IST plan to develop and market to a wide cross-section of homeowners and businesses a hand-held detection unit. - PB
