STIZ Scientific Technologies

Scientific Technologies Incorporated (Nasdaq:STIZ), a leading North American provider of automation safeguarding products and services, recently received a Product of the Year award for its innovative OptoShield OS3100 Laser Light Safety Scanner -- an advanced area guarding scanner which employs laser light to monitor entry into a user-configurable safety detection zone and send a stop signal to a guarded machine. The award honors the top new products as voted on by the readers of PLANT ENGINEERING magazine. "We are honored to be recognized by the readers of PLANT ENGINEERING magazine for introducing one of the best new industrial products of 2005," commented Joseph J. Lazzara, President and Chief Executive Officer of Scientific Technologies, Inc ("STI"). "The OptoShield is an excellent choice for safeguarding hazardous work cells, transfer lines, robot stations, internal press guarding, irregular shaped or changing areas and automated guided vehicles." According to a January, 2005 report issued by Venture Development Corporation on the estimated $250 million North American market for machine safeguarding equipment, laser scanners represent the second highest expected product growth segment, by percentage, in the safeguarding equipment market from 2004 to 2007. According to VDC, on a global basis, laser scanners are expected to be an estimated $90 million product segment by 2007. Designed and manufactured in the United States by STI, the OptoShield OS3100 is now available for customer deliveries. The scanner can be used to protect personnel from stationary hazardous machinery, such as work cells, robot stations and internal press guarding or moving equipment, such as automated guided vehicles and transfer carts. With a detection radius of 15 meters, the OptoShield can also be use in security applications for the detection of intruders into a user-defined security zone. Intuitive configuration software facilitates easy navigation and user set-up, allowing the OptoShield to be user configured in a large number of area guarding arrangements. The OptoShield introduces significant advancements over similar types of sensors with advanced diagnostic communications and superior interface options. OptoShield provides diagnostic features not typically available in safety scanners. These features include a two-digit numeric display, four standard LED status indicators and patented Intrusion Indicators that identify where the safety zone is encroached without the need for difficult diagnostic searches and an external computer display.
