3 results about "Explosive material" patented technology

A multi-stage process utilizing one or more radiation sensors on a distributed network for the detection and identification of radiation, explosives, and special materials within a shipping container. The sensors are configured as nodes on the network. The system collects radiation data from one or more nodes and compares the collected data to one or more stored spectral images representing one or more isotopes to identify one or more isotopes present. The identified one or more isotopes present are corresponded to possible materials or goods that they represent. The possible materials or goods are compared with the manifest relating to the container to confirm the identity of materials or goods contained in the container or to detect and/or identify unauthorized materials or goods in the container. For shielded materials, explosives and other types of material detection, a neutron pulse device could be incorporated into the system.

The invention belongs to the technical field of laser Raman spectrum and trace narcotic detection and in particular relates to a high-sensitivity SERS (surface-enhanced Raman scattering) sensor active substrate used for detecting narcotics and a preparation method thereof. The invention provides an SERS active substrate. The SERS active substrate is of a precious metal three-dimensional nano porous structure coated on a substrate, wherein the precious metal materials are silver, copper and/or gold. The high-sensitivity SERS sensor active substrate has SER activity and high repetitive rate, and can be used for detecting trace compounds such as narcotics, explosives and the like.

The invention discloses an explosive information collector which comprises a microprocessor, a wireless communication transceiver, an electronic tag, a timer, a GPS locator and a liquid crystal display screen, wherein the output end of the timer is connected with the input end of the microprocessor, the output end of the electronic tag is connected with the input end of the microprocessor, the output end of the GPS locator is connected with the input end of the microprocessor, the input end of the liquid crystal display screen is connected with the output end of the microprocessor, and the wireless communication transceiver is connected with the microprocessor. With the explosive information collector, explosives can be effectively supervised, explosives can be prevented from flowing into the society to jeopardize public security and personal safety due to poor supervision, and adverse consequences caused by misoperation due to poor communication can be avoided.
