INVISA ANNOUNCES NEW DIGITAL PRESENCE SENSING TECHNOLOGY

This document is available in .PDF format Inventions covered in this latest patent application are used in our current safety products and are anticipated to shape the future of capacitive presence sensing. We anticipate that these latest inventions will move the company's InvisaShield™ technology to the next level making it more robust and flexible... allowing it to be used in a much larger number of applications. It also raises the bar in areas of electromagnet interference rejection, false alarm prevention, and ease of setup and adjustment. Other benefits of this latest development are additional flexibility in communicating status, multiple status outputs, remote selectable sensing levels, remote selectable operating states, remote selectable maintenance mode, and attempted field override monitoring and detection. According to Bob Fergusson, Engineering Manager, "This patent helps give our technology a new level of protection. It is the basis of our present safety products that are now being sold into the marketplace. Our new museum security products, which are planned to be introduced later this year, will also incorporate these new technology developments. The planned microcontroller version of our next generation of safety products will implement some of the new more advanced features protected by this patent, features that will allow for easier setup and a more robust operation of the sensor. We believe the new technology covered under this patent will give us some unique advantages as we look at new applications in the safety and security markets." According to Steve Michael, Invisa's acting President, "We believe that Invisa's latest capacitive technology is the wave of the future because it enhances both function and capability. We are dedicated to making capacitive sensing the new standard in safety and security. We believe that our latest technology advancements and our continuing commitment to development confirm that Invisa is a technology leader in new and innovative products for the safety and security markets." Invisa's versatile, reliable, compact next generation presence sensing solutions are targeted to the multibillion dollar global electronic life safety and security markets. InvisaShield technology, an advanced implementation of capacitive sensing, is resistant to known methods of circumvention. It does not employ infrared, laser, ultrasound or microwave radiation. Used in security applications, InvisaShield technology can detect intruders who violate a sensing zone ranging from millimeters up to one meter. Invisa sensors have been in service at a major New England museum since April 2003. Invisa's SmartGate® safety systems incorporate the InvisaShield capacitive sensing technology which generates an invisible protective field that moves with and precedes the potentially hazardous leading edge of powered gates, garage doors, sliding doors and other powered closures.
