Detection FAQ's

Q.) Is the GEN 2 system designed to detect any contraband?
A.) The system is design to detect for any anomalies against the human silhouette. These anomalies are created by any suitable difference in millimeter wave emission, absorption or refraction between the subject and the object, such as thick packets of currency or paper.

Q.) Is it possible to change the sensitivity level to not detect any metal the size of a coin or a belt buckle (1" x 1")?
A.) The sensitivity level is fully adjustable by the operator. However, the smallest possible object size to detected is 2” x 2" pixel size or approximately 3"x5" actual size.

Q.) Does the software allow the user to color code metals, liquids, guns differently?
A.) No, the software currently color codes threats based on a combination of size and contrast parameters.

Q.) Is the software designed to only differentiate between large and small objects?
A.) No, the software currently color codes threats based on a combination of size and contrast parameters.

Q.) Does the software allow the user to change the sensitivity of the system?
A.) Yes, there are various opportunities to change the sensitivity of the system.
For example:

• Increase sensitivity of the system to be in tune with elevated levels of threat assessed to assure overall safety.
• Increase the sensitivity to detect smaller objects, if in loss prevention applications, the items at risk are smaller the detection size of the standard set up.
  

Q.) Will the GEN 2 system image through wet materials?
A.) Yes, the system will image through any normal weight shirt or t-shirt fabric (e.g. cotton, polyester, wool, nylon, etc.), whether wet or dry. If a wet article of clothing if that piece of clothing is made of a heavy enough material (over 1/8” thick) and holds a significant amount of water, the system may not be able to see anything underneath the water soaked material.

Q.) Will the GEN 2 system image through plastic materials?
A.) Yes, the system will image through materials that repel water, such as a plastic based raincoat or slicker (e.g. rain coats made with plastic up to 1/8” thick).

Q.) Will the GEN 2 system image through metallic materials?
A.) No, the metallic materials, regardless of thickness, will always be detected by the system as an object of interest.

Q.) Would metal film wrappers used for chips and candy block recognition of objects inside?
A.) Metal film wrappers used for chips and candy would be detected by the system as an item of interest and would cause a secondary screening of a subject.

Q.) Does the GEN 2 system already recognize non-threat items such as cell phones and PDAs?
A.) Objects that are of a common rectangular shape such as cell phones and PDAs, are virtually indistinguishable from other objects of similar shape and size. Therefore, they will be detected as potential threats.

Q.) How will the GEN 2 system handle grouped multiple objects?
A.) Detection of an object is dependent on its physical size and shape above defined threshold. Grouped objects less than one inch (1) apart would not be discernable as separate items and once the area of the whole group reached the defined threshold, the group would be detected. Items more than one inch (1) apart would result in separate detection boxes.

Q.) How would the GEN 2 system image a concealed item between a carried infant and a parent?
A.) The system cannot see through humans or human. It is recommended that one person be viewed at one time.

Q.) How would the system image a concealed item between two adults close together?
A.) The GEN 2 system cannot see through humans or human skin. It is recommended that one person be viewed at one time.

Q.) How would the system image a concealed item between folds of skin?
A.) The GEN 2 system cannot see through humans or human skin.

Q.) Can system currently recognize non-metallic threats (i.e. ceramic knives, explosives, different liquids such as water and gasoline)?
A.) Yes, ceramic weapons and plastic explosives exceeding the size threshold (3"x 5") will be detected. Also, High density plastics or metals are used to contain hydrocarbon combustibles; therefore, known liquid explosives (including gasoline) would be detected due to the fact that they would be carried in detectable containers that exceed the size threshold.

Q.) What happens if there is a threat and someone else walks into the scanning area?
A.) Warning cues will change from solid to flashing upon interruption of the event (e.g. someone walking in front of the object, a hand moving over the object). On-screen persistence of disappeared objects is user selectable. It is recommended that users base reactions and subsequent procedures on event traps.

Q.) How does it handle multiple threats?
A.) The GEN 2 system can identify up to 50 threats simultaneously. A legend key indicates the type of threat. As the number of known objects increases, the impact on recognition time is negligible.
