The BOSS is a unique, fast, non-intrusive, inexpensive, high sensitivity detector designed to detect metal objects hidden in body cavities. It is commonly used in prisons, detention centres, customs and border patrol facilities, precious metal mines and refineries, coin counting facilities, jewellery and watch manufacturing and computer component manufacturing. BOSS has undergone extensive testing at US State and Federal Corrections facilities.
In corrections facilities it is used to scan inmates for weapons and contraband objects hidden in body cavities. At some sites visitors are also screened. Typical objects being targeted are razor blades, handcuff keys, paper clips, knives, shanks and tools. It also detects metal foils and objects such as detonator caps.
BOSS minimises the need for unpleasant intrusive manual searches and increases the safety of officers and inmates. Because the measurement method is non-intrusive, it eliminates the liability and safety issues associated with manual searches. It also saves the time and expense involved in X-raying a person suspected of concealing contraband metal.
In a recent A&E Channel TV documentary, officials from New York City's Rikers Island Jail reported that aggressive security measures, which include screening with the scanner, have cut inmate gang related violence by 90%.
The screening procedure is safe, fast and efficient. The person being screened simply positions his/her chin near the oral sensor and then sits momentarily in the chair. The entire procedure takes just a few seconds. Magnetic field sensors housed in the seat of the chair and the oral sensor assembly automatically interrogate for the presence of metal. Audio and visual alarms are activated when metal is carried into the magnetic field. An alarm remains activated for the duration that an object is within the low intensity magnetic field.
The measurement method is unique in that it detects ferrous and non-ferrous objects that are either stationary or moving. Eddy current field detection sensors are installed within the chair assembly. The geometry of the chair and oral sensor configuration provides tight magnetic coupling between the sensor and a concealed metal object. Because of the excellent geometry and the combination of dynamic and non-motion detection techniques, small objects are more reliably detected than with a walk-through or handheld detector.
