Screening portal, system and method of using same
| DWPI Title: Portal for screening object for target substance, such as explosive materials, has collector that is positioned outside test space and operatively connected to portal for collecting samples removed from object |
| Abstract: A portal, system and method for screening an object for a target substance is provided. The portal includes an inflatable bladder expandable to form a test space for receiving the object and a plurality of nozzles positioned about the inflatable bladder. The nozzles are in fluid communication with a fluid source for directing air over the object whereby samples are removed from the object for examination. A collector is operatively connected to the inflatable bladder for collecting the samples removed from the object. A detector is operatively connected to the collector for examining the removed samples for the presence of the target substance. At least one preconcentrator may be operatively connected to the collector for concentrating the samples collected thereby. |
| Use: Portal used in a system (claimed) for screening an object for a target substance. Can be used for collecting samples from objects to screen for the presence of target substances, such as explosive materials. |
| Advantage: Provides for optimized screening operations such as optimized sample removal, optimized efficiency and/or optimized comfort for the object. The screening system has low cost design and operation, quick operation, high quality sampling, non-contact operation, replaceability of components, optimized air flow, lightweight design, quick assembly/disassembly, accurate detection, additional functions, modularity, replaceable components and/or parts, and trace detection capabilities. |
| Novelty: The portal (104c) has an inflatable bladder (106c) expandable to form a test space (112c) for receiving the object (102), the test space having a first opening for receiving the object and a second opening for discharging the object. The openings form a passage (246) through the portal through which the object can pass through the test space. Nozzles (108) are positioned about the inflatable bladder. A collector (126) is positioned outside the test space and operatively connected to the portal for collecting the samples removed from the object. |
