摘要:
A scanning system (10) comprises a radiation source (12) arranged to direct radiation towards an object (14), a detection means (16) arranged to detect the radiation, and control means (18) arranged to control the source so that it produces pulses of radiation, to define a check condition, to process signals from the detection means to determine whether they meet the check condition, and to vary the frequency, the duration and the energy profile of the pulses dependent on whether the signals meet the check condition.

A flash heater element (200) includes a first surface (202) having a central region (234) and an electrical flow path (220) disposed on the first surface. The electrical flow path includes a central portion (240) disposed at least partially within the central region and a peripheral portion (238) disposed peripherally outwardly from the central region. A width (244) of the electrical flow path is greater within at least a portion of the central portion than the width (246) of the electrical flow path within the peripheral portion. Also disclosed is a detection system (100) comprising a housing (110), a desorber (112), a heater (130), flash heater element (200) and a detector (114).
摘要:
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.

The present invention provides a four-sided scanning system for vehicles that uses a combination of backscatter and transmission based X-ray imaging to achieve material discrimination. In one embodiment, the system is designed as a mobile, drive -through system, which can be folded and stowed in a truck and can be conveniently deployed at any place when required.
摘要:
A drive-through scanning system comprises a radiation generating system arranged to generate radiation at two different energy levels and direct the radiation towards a scanning volume, detectors arranged to detect the radiation after it has passed through the scanning volume, and a controller arranged to identify a part of a vehicle within the scanning volume, to allocate the part of the vehicle to one of several categories, and to control the radiation generating system and to select one or more of the energy levels depending on the category to which the part of the vehicle is allocated.
摘要:
The present specification discloses a beam chopping apparatus, and more specifically, a helical shutter for an electron beam system that is employed in radiation-based scanning systems, and more specifically, a beam chopping apparatus that allows for variability in both velocity and beam spot size by modifying the physical characteristics or geometry of the beam chopper apparatus. The present specification also discloses a beam chopping apparatus which provides a vertically moving beam spot with substantially constant size and velocity to allow for substantially equal illumination of the target. In addition, the present specification is a beam chopping apparatus that is lightweight and does not cause an X-ray source assembly employing the beam chopper to become heavy and difficult to deploy.
摘要:
The present invention is a self-contained mobile inspection system and method and, more specifically, improved methods and systems for detecting materials concealed within a wide variety of receptacles and/or cargo containers. In particular, the present invention is an improved method and system with a novel boom structure that reduces the weight of the boom. The single, light-weight boom of the inspection system is relatively compact in a stowed configuration and has a low height and center of gravity lending to greater maneuverability.
