摘要:
In a transportation security technique, images are stored that are received from image capturing equipment deployed at respective screening nodes. The images are analyzed using a machine learning model, where presence of a particular object in an image indicates that a threat condition exists at the screening node. The analyzed images are transmitted to threat assessment components in accordance with predetermined criteria. An indication that the particular object is observed in the image is received from the threat assessment components. An indication that the particular object is observed in the image is transmitted to the screening node responsive to receiving the indication that the particular object is observed in the image. An indication of whether the particular object is present at the screening node is received. The machine learning model is trained based on the received indication of whether the particular object is observed in the image.
摘要:
The present specification discloses systems and methods for identifying and reporting contents of a tanker, container or vehicle. Programmatic tools are provided to assist an operator in analyzing contents of a tanker, container or vehicle. Manifest data is automatically imported into the system for each shipment, thereby helping security personnel to quickly determine container contents. In case of a mismatch between container contents shown by manifest data and the contents as ascertained from the scanning system, the container or vehicle may be withheld for further inspection.

Described are a method and apparatus for determining based on motion data when an individual wearing a dosimeter is active. Also described are a method and apparatus for determining based on motion data whether an individual was wearing a dosimeter when the dosimeter was exposed to radiation. Also described are a method and apparatus for determining based on motion data whether a dosimeter was in a particular location when the dosimeter was exposed to radiation. Also described are a method and apparatus for determining based on motion data where on the body of an individual the individual was wearing a dosimeter when the dosimeter was exposed to radiation. Also described are a method and apparatus for determining based on motion data the probability that an individual is wearing a dosimeter that is assigned to the individual.

The present specification discloses systems and methods for integrating manifest data for cargo and light vehicles with their X-ray images generated during scanning. Manifest data is automatically imported into the system for each shipment, and helps the security personnel to quickly determine the contents of cargo. In case of a mismatch between cargo contents shown by manifest data and the X-ray images, the cargo may be withheld for further inspection. In one embodiment, the process of analyzing the X-ray image of the cargo in conjunction with the manifest data is automated.
摘要:
An examination apparatus examines an item including a person or a container and has a determination unit for determining a relevance level which can be assigned to the item under examination, in particular a hazard level, and an image capture unit for capturing an image of the item under examination. The examination apparatus has a database, an automated evaluation unit for automatically evaluating at least one section of the image using the database, an evaluation unit operated by a user for the visual evaluation of a section of the image by the user, and an input unit for inputting at least one evaluation input by the user, and a database processing unit for processing the database. The database processing unit processes a database entry using the evaluation input in conjunction with the determination of the relevance level.

摘要:
Described is a radiation dosimeter including multiple sensor devices (including one or more passive integrating electronic radiation sensor, a MEMS accelerometers, a wireless transmitters and, optionally, a GPS, a thermistor, or other chemical, biological or EMF sensors) and a computer program for the simultaneous detection and wireless transmission of ionizing radiation, motion and global position for use in occupational and environmental dosimetry. The described dosimeter utilizes new processes and algorithms to create a self-contained, passive, integrating dosimeter. Furthermore, disclosed embodiments provide the use of MEMS and nanotechnology manufacturing techniques to encapsulate individual ionizing radiation sensor elements within a radiation attenuating material that provides a “filtration bubble” around the sensor element, the use of multiple attenuating materials (filters) around multiple sensor elements, and the use of a software algorithm to discriminate between different types of ionizing radiation and different radiation energy.
摘要:
A method and system is provided for implementing an integrated detection and monitoring system. Aspects of the present invention include mounting at least detector into a vehicle to provide a mobile detector. The mobile detector is then transported to a security checkpoint and positioned along side a vehicle pass-through. As a vehicle passes through, the mobile detector scans the vehicles to detect levels of one or more designated materials. If any material detected exceeds a threshold alarm level, the detected level of the material is stored in a file that is associated with the vehicle, and the file is wirelessly transmitted to a command center to notify authorities.
