Invisa's SmartGate Technology Featured in Security Magazine SARASOTA, Fla., May 20 /PRNewswire-FirstCall/ -- Invisa, Inc. (BULLETIN BOARD: INSA) , an electronic life safety and security company that has commercialized patented presence-sensing technologies, was recently featured in Security Magazine, an industry publication that covers new developments within the security industry. In the article "Focus on Gates," Invisa's SmartGate(R) sensor was highlighted for its low-maintenance, its ease of use (there are no output lenses to keep clean, no bulbs or emitters to burn out, and no expensive in- the-ground installation) and its non-contact, safety-sensing features. Based upon InvisaShield(TM) capacitive-sensing technology, SmartGate places an invisible field around conductive objects. An object can be static or moving; in either case the system detects its presence. SmartGate can be incorporated into powered gates, garage doors, sliding doors and other powered closures. Invisa's technology is also used to detect intrusion of people in a near-field zone of security; first-generation security sensors using InvisaShield(TM) technology are in service at a major museum in New England. Through extensive R&D efforts, Invisa has developed versatile, reliable and compact next-generation, presence-sensing solutions targeted to the $100 billion-plus global electronic life safety and security markets. InvisaShield, a robust and advanced implementation of capacitive sensing technology, is highly resistant to known methods of circumvention. It is unique in that it does not employ infrared, laser, ultrasound or microwave radiation. Invisa holds one patent and has six more applications pending.
