Paper Abstract

In our current military environment, many operations are fought with small, highly mobile reconnaissance and strike forces that must move in and out of hostile terrain, setting up temporary bases and perimeters. As such, today's warfighter has to be well equipped to insure independent operation and survival of small, deployed groups. The use of unattended ground sensors in reconfigurable sensor networks can provide portable perimeter security for such special operations. Since all of the equipment for the missions must be carried by the warfighter, weight is a critical issue. Currently, batteries constitute much of that weight, as batteries are short-lived and unreliable. An alternative power source is required to eliminate the need for carrying multiple replacement batteries to support special operations. Such a battery-free, replenishable, energy management technology has been developed by Ambient Control Systems. Ambient has developed an advanced mid-door photovoltaic technology, which converts light to energy over a wide range of lighting conditions. The energy is then stored in supercapacitors, a highly robust, long-term storage medium. Ambient's advanced energy management technology will power remote sensor and control systems 24 hours/day, 7 days/week for over 20 years, without batteries, providing for ongoing detection, surveillance and other remote operations.
