INVISA RECEIVES PATENT

This document is available in .PDF format Invisa's newest patent covers critical aspects of using its patented technology in safety applications. A unique aspect of capacitance based technology is versatility that permits sensing applications not otherwise possible or practical. Invisa's technology uses capacitance to form electronic sensing zones around a Sense Element. We call this Sensing Element an "antenna". Our most recently issued U.S. patent protects antenna designs and applications developed and used in our current and future safety products. According to Carl Parks, Chief Operations Officer, "Invisa has devoted significant research and development resources to antenna design. The antenna is where the "rubber meets the road" in capacitance based sensing. By utilizing different types of materials and maximizing installation and spacing techniques we optimize our sensing capability in various applications. We believe that the issuance of this patent recognizes and protects our unique developments in antenna design and development." According to Steve Michael, Invisa's acting President, "Over the years, many highly qualified inventors and well funded companies have attempted to harness the power and versatility of capacitance based non-contact sensing. We believe that Invisa's breakthrough InvisaShield™ Technology is the only capacitance based non-contact sensing technology proven to be stable and reliable for use in safety and security products. However, technology never stands still and we are committed to protecting our leadership position through ongoing R & D and through expanding our patent position. We believe that our newest patent, together with our other patent and four pending patent applications, represent a solid and growing patent position which enhances our competitive and technology advantages." Invisa delivers versatile, reliable, compact next-generation presence-sensing solutions targeted to the 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 does not employ infrared, laser, ultrasound or microwave radiation. The company's SmartGate® safety systems incorporate InvisaShield capacitive-sensing technology to generate an invisible protective field around or preceding the leading edge of powered gates, garage doors, sliding gates & doors and other powered closures.
