INVISA AWARDED THIRD PATENT SUPPORTING IP POSITION IN SAFETY AND SECURITY SENSING

New U.S. Patent Supports Invisa's Leadership in Capacitance Sensing for Safety and Security Applications Incorporating Digital Reliability and Adjustability

This document is available in .PDF format Commenting on the news, Carl Parks, Invisa's Chief Operating Officer stated, "We are very pleased to have been awarded the intellectual property protection afforded by this patent. Our recent developments in the digital management of our patented and proven sensing technology will prove invaluable as we target new markets for our products. This patent provides expanded IP protection, and further solidifies our lead position in the industry as we aggressively move into the next phase of our product rollout in a number of targeted safety and security applications." This patent builds on Invisa's portfolio of two prior issued patents, two pending patents and numerous provisional patent applications. The latest patent protects Invisa's technological leadership by applying digital technologies to capacitance sensing for safety and security applications. By applying digital technology to Invisa's patented sensing technology, the Company believes that it will achieve a number of potential benefits, including:

• Lower sensor manufacturing costs.
• Expand existing markets and open new markets for Invisa's sensing products through easier installation and set-up and easier maintenance.
• Efficiency gains through continuously updating the sensor for changes in the environment, giving the sensor more flexibility for adapting to new safety and security applications.
• Enhanced reliability because it is less susceptible to electronic noise spikes caused by lightning or other electromagnetic interference.
• Opportunity for new developments in Invisa's sensing products due to the fact that it can be implemented in complex programmable logic devices (CPLD), field programmable gate arrays (FPGA), or a microcontroller.

Invisa's line of SmartGate® safety equipment is the only electronic non-contact safety system designed to provide an invisible field that moves with and precedes the gate arm. If the gate arm is coming down on a pedestrian, bicycle, motorcycle, car or other vehicle, the gate arm is signaled to stop and reverse before any contact has been made to avoid injury and damage. Invisa's line of SmartGate safety equipment is the only electronic non- contact safety system designed to provide an invisible field that moves with and precedes the gate arm. If the gate arm with SmartGate senses a pedestrian, bicycle, motorcycle, car or other vehicle, the gate arm is signaled to stop and reverse before any contact has been made to avoid injury or damage. If you are a manufacturer of safety barriers or security systems and would like more information on incorporating InvisaShield™ technology into your systems via the Invisa OEM partner program, please contact Carl Parks, Invisa Chief Operating Officer, via e-mail at cparks@invisa.com or call 941-355-9361, ext. 124. Invisa presence-sensing solutions serve the electronic life safety and security markets. Invisa's proprietary InvisaShield technology is based upon enhanced capacitive sensing and is resistant to known methods of circumvention without employing infrared, laser, ultrasound or microwave radiation. InvisaShield can detect intruders who violate a sensing zone ranging from millimeters up to 1 meter. Invisa's SmartGate safety system 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. With an estimated 60,000 new parking control gates installed each year, and an installed base of over 1,000,000 gates world wide, an enormous market currently exists for Invisa's SmartGate technology. In addition to moving gates, Invisa is currently developing a similar line of products based on its patented InvisaShield technology for the overhead door and museum security markets.
