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.

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 for inspecting receptacles and / or cargo containers using a single boom placed on a turntable with pivot points to allow for folding and unfolding of the boom, such that the inspection system is relatively compact in a stowed configuration and has a low center of gravity lending to greater stability.

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of interleaved pulses having different energy levels, for example alternating 4 MeV and 6 MeV pulses or other energies where the difference in levels is at least approximately 1 MeV and less than approximately 5 MeV. The pulse repetition rate can be 100-400 pulses per second or more. In an embodiment, a cool down calculation is combined with automatic frequency control to provide stable energy and dose per pulse even upon restarting of pulsing after an “off” period of indeterminate duration.

Provided herein are systems and methods for operating a traveling wave linear accelerator to generate stable electron beams at two or more different intensities by varying the number of electrons injected into the accelerator structure during each pulse by varying the width of the beam pulse, i.e., pulse width. The electron beams may be used to generate x-rays having selected doses and energies, which may be used for cargo scanning or radiotherapy applications.

The invention relates to a scanning device, in particular to a logistics goods scanning device capable of rising and falling. According to the technical purposes of the logistics goods scanning devicecapable of rising and falling, time and labor are saved, the work efficiency is high, dust on goods can be removed, and waybill information on the goods is not affected. In order to achieve the technical purposes, the logistics goods scanning device capable of rising and falling is provided and comprises a top plate and the like; the left side face and the right side face of the top plate are each provided with a supporting column; the supporting columns are symmetrically arranged; a conveying device is arranged between the middle portions of the inner side faces of the supporting columns onthe left side and the right side; the top plate is provided with a scanning device; and a scanning part of the scanning device is located above the conveying device. According to the logistics goods scanning device capable of rising and falling, due to a cleaning device, the scanning head can be cleaned, and therefore the scanning head can perform scanning on goods faster; and a dust removing device can be used for removing dust on the goods, and the effects that time and labor are saved, the work efficiency is high, and dust on the goods can be removed are achieved.

The invention discloses an automatic cargo loading and unloading and counterweight platform of an express delivery drone, which includes a platform base, a fixed support, a first manipulator, a bracket, a horizontal guide rail, a mobile slide, a second manipulator, a cargo information reader and a controller , the fixed support is set on the platform base to fix the manipulator one, and the manipulator one is under the control of the controller to load and unload the goods on the shelves in the unmanned aerial vehicle cabin; the horizontal guide rail is set on the bracket, and the mobile slide table is set On the horizontal guide rail, the manipulator 2 is set on the mobile slide table, and the cargo information reader is set on the manipulator 2. The cargo information reader transmits the scanned and read cargo information to the controller, and the controller controls the manipulator 2. Controls for counterweighting the unmanned cabin. Due to the adoption of the above-mentioned structural form, it has the functions of automatic loading and unloading of goods, reading of goods information and realizing the intelligent counterweight of goods according to the scanned data, so it is suitable for the automatic delivery platform of drones in the express delivery industry in the future.
