COLORADO GUNMAN COULD HAVE BEEN STOPPED BY SECURITY CHEMICAL PATTERN SENSOR

FEAR AT THEATERS/EVENTS DRIVING INTEREST IN NEW "SNIFFER" DETECTION CONCEPT
ORLANDO, FL… The deadly "Batman" shooting attack at a Colorado midnight movie might have been stopped before it began if an experimental "sniffer" system developed by "WEAPONDETECT, a Florida technology incubator, had spotted the bullets. With the latest in the trilogy series featuring many "high tech" devices, the detection of the electrical field generated by primers and propellants in bullets in a new generation of security devices for theater chains, public venues, and banks is attracting those looking for ways to find "bad guys" before they act. "While those who operate large public facilities certainly don't want such incidents, the public does not want to be reminded they are possible each time they go to a movie or a concert", said Howard Sidman, CEO of the Virginia "think tank" that pioneered studies of explosive's electrical signatures for detection use. He credits a scientific "new thinking approach" for finding a way to provide detection before an incident. "Detecting the presence of the bullets instead of trying to spot the weapon seems perfectly logical in hindsight once you can do it", said Michael Shulman, Research Coordinator for "WEAPONDETECT", a Florida technology incubator developing funding for packaging the components into a doorway sensor system. "The components for a series of "sniffer" technology products are completed and are undergoing final testing."Hedge Funds, "angels" and even a UAE Sheik have been contacting us to get in on the ground floor of this new security "niche" industry segment. The first production will be made available to members of the electronic security industry association for installation at selected movie theaters "around September 20th" he said.
According to a Northeastern University criminologist and serial killing author (James Fox), mass killing incidents like those at Virginia Tech may have public awareness due to high media exposure but records show that there are a great many more. "The U.S. experienced 645 such events(with 4 or more victims) between 1976 and 2010" reports Jennifer Rubin of the Washington Post. The topic has become a major Liberal "talking point" in the current election battles.

The explosive detection sensor will detect the bulk explosives' naturally occurring ultra-low-frequency (ULF) electric field.
SPECIFICS OF APPLICATION
The source of the explosives' electric field is from naturally-occurring (<5 Hz) very long-lasting static electrification effects that result from their content, manufacture, storage and end-use.
CLASSIFICATION OF EXPLOSIVE GROUPS
Commonly used high explosives are classified into three groups by the primary component when the weight is greater than fifty percent. Other specialty formulations do exist but are not commonly available.
cyclo-tri-methylene-tri-nitr-amine (RDX formulated as C4)(also HMX and tetryl) cyclo-tetra-methylene-tetra-nitr-amine (HDX formulated as CX)
penta-erythrite-tetra-nitrate (PETN plus RDX formulated as Semtex) ammonium-nitrate (plus select hydrocarbon oil formula as fertilizer bomb) glycerol-tri-nitrate (nitroglycerin formulated as dynamite) (also smokeless gunpowder) 2,4,6-tri-nitro-toluene (TNT)
SENSOR OPERATION CONFIGURATION
• Passive standoff sensors operate in the ULF (below 4 Hz near DC) electric fields and acts as a transducer that converts electric energy into a measurable force.
• The sensor responds to ULF electric field source generated by the target.
• Selective detection and identification of the target electric field is achieved by the defined permittivity of the dielectric medium and the geometric and electrical configuration of the capacitive elements of the detection circuit.
• Eventual plans are to integrate these sensors into UAVs and robotics to allow even greater standoff detection ability.
CHARGE PATTERN DETECTION
The passive unattended sensor detects changes in the charge pattern in the detection area. Specifically, it detects the change in "volts per meter" in the ULF < 10 Hz range.
The sensor can be tailored geometrically and by materials-of-construction to optimize detection performance for specific applications.
CHANGE IN FIELD
When the target explosive moves into the detection area, the explosive's ULF electric field changes the charge pattern on the materials in the detection area. The explosive's movement changes that capacitive charge coupling and creates a charge redistribution that is detectable by the sensor.
APPLICATIONS IN MASS TRAFFIC PATTERNS
The establishment of sensors in congregate areas such as movie theaters, sporting arenas, concert halls, and other locations to detect passage of the identified explosive potential is most likely to be used to signal apprehension personnel rather than immediately cause concerns among audiences. While the reaction of the sensor is instant and could alert general traffic, the risk of crowd reaction and panic suggests a more subdued signal concept.
The technology will be applied for use at fixed positions for walk- through/drive-through detection of explosives to increase safety and decrease risk. This will enable detection of suicide bombers, loaded guns or explosives on people or in trucks, cars, containers, etc. at check points, entrances or border crossings as a means of indicating an alert. Sensor operation will not change the threat level pending reaction of the security personnel.
