Remote site monitors protect facilities that house sensitive equipment
Chartered in 1746, Princeton University, N.J., was the fourth college established in colonial America. Yet, like most schools and universities today, it experiences a 21st-century need to protect the facilities that house expensive equipment, and sensitive intellectual property and data.
“The threats we encounter are mostly heat and humidity,” says Chris Tengi, systems and network administrator at Princeton University's department of computer science, “although we are certainly concerned about unauthorized entry or human actions that can compromise our systems.”
The facilities that Tengi supports include the department's main computer room and labs that house workstations, PCs, and other resources for Princeton's undergraduate and graduate students in computer science.
To protect these areas, Tengi acquired three SNMP-Link Model SL61 Remote Site Managers made by Omnitronix. The Remote Site Monitor keeps tabs on power supplies and communications/networking components — as well as the physical conditions that affect the health of such equipment — and then provides the network interface and intelligence required to get these devices into the control of the network.
“We used the even sensors to send SNMP traps so that if they detected high humidity or temperatures that are too high or too low, the corresponding trap will generate an e-mail message to our pagers,” says Tengi.
Tengi says that accidental environmental problems resulting from human intervention now are handled reliably by the event sensor system. For example, in some of the computer lab facilities, the air-conditioning thermostats are accessible by occupants.
“If they raise the thermostat too much to warm the room, it could get too hot for the equipment,” says Tengi. “But now the sensors will detect the temperature rise at whatever threshold we have set, and we can make corrections before the equipment is affected.”

Fingerprint ID technology confronts the challenges of food service in schools
Food Service Solutions
The Penn Cambria and Wilson School Districts, Pa., have adopted fingerprint scanning and identification systems to handle a host of problems from slow lunch lines, lost lunch money, cumbersome payment, lunch fraud and bullying, to falling National School Lunch Program (NSLP) participation.
With a fingerprint ID system in the cafeteria, students simply place a forefinger on a small fingerprint reader by the register. In seconds, the system translates the electronic print into a mathematical algorithm, discards the fingerprint image, and matches the numerical output to the student's meal-account information. The software by Food Service Solutions plots 27 points on a grid that correspond with the fingerprint's ridges to achieve a positive identification.
Fingerprinting is voluntary and done typically when the student enters the school system along with enrollment paperwork. Kids are fingerprinted just once, and the mathematical algorithm produced stays with them until they graduate. Those declining fingerprint IDs can use cash or other methods.
This fingerprint technology is an alternative to magnetic-striped cards, using cash or lunch tickets, which can be lost, stolen, destroyed or misused.
Teachers also are finding that by eliminating the daily handling of lunch money or tickets, especially in kindergarten or elementary classrooms, they can free up time for added instruction. Because parents can set up a lunch account linked to a biometric system for their child's use, they can not only be sure their child has enough money for lunch each day, but also can monitor what they are buying.

Locker latching system
Lyon Workspace Products
The patent-pending locker latching system uses nano (miniature) roller technology to provide up to 10 times the resistance to break-ins compared with existing locker latching systems. In this case, resistance is measured as the pounds of force required to pull a locker door open in a variety of laboratory tests simulating real life. The actual nano roller is made of powdered metal for resistance to wear. A new nylon lockbar guide ensures proper lockbar alignment for smooth operation, while reducing overall noise.

Protecting historical treasures
Roof insulation helps preserve artifacts in special collections library
The original papers of Thomas Jefferson, rare books and maps illuminating the birth of a nation are preserved at the Mary and David Harrison Institute for American History, Literature and Culture and the Albert and Shirley Small Special Collections Library at the University of Virginia, Charlottesville.
This $26 million building has 60,000 square feet of underground space that conserves land and protects the artifacts at 63 degrees and 33 percent relative humidity. The collection is insured for $300 million.
Double walls, service drains and water alarms were installed around the building. In addition, a 36-inch-thick concrete slab was poured under the collection. The above-ground, 11,000-square-foot institute contains rooms for viewing the collection, and has a brick neoclassical exterior reflecting the Jeffersonian campus.
The originally specified metal roof deck could have exposed the interior to moisture. Instead, the Nail Base roof insulation, which delivers a 25.6 R-value at 4.5-inch thickness, was used and plays a major role in protecting the collection. The Nail Base insulation panels are composed of a layer of ACFoam polyiso insulation bonded to 7/16-inch APA/TECO-rated OSB on the topside and a felt facer on the bottom.
The roof also features copper-trimmed dormers, flat-locked and soldered lead-coated copper by Hussey, and copper snow guards by Berger Brothers on the 6/12 pitch roof portions.
