Remote sensor detects airborne chemicals

Technest Holdings’ subsidiary EOIR Technologies developed the Automated Adaptive Chemical Examination System (AACES), a remote-sensor device that detects and classifies chemicals released into the air during a terrorist attack or a chemical emergency. The AACES chemical detection sensor does not need to come in contact with chemicals to detect and identify them. It can make assessments from a remote location, according to the company.

The U.S. Army is testing the product.

Japan implements ultra wideband wireless system in fall 2005

Japan’s Ministry of Internal Affairs and Communications said it would deploy an ultra wideband (UWB) wireless system. With a transmission speed of up to 500 megabits per second, the system will send images recorded by a high-quality digital video camera to a number of home information appliances, such as personal computers and printers. As early as next spring, the ministry plans to inaugurate a high-speed wireless local area network that offers full-time access to the Internet at a speed of 100 mbps. Although its range is only about 10 meters, the UWB system is expected to improve the communication environment at home, according to the ministry.
