Abstract: A method for inspecting at least one vehicle with an inspection system, the inspection system and the at least one vehicle being configured to move relative to one another during an inspection of at least one part of the vehicle, the method including controlling, by a controller, an inspection dose of inspection radiation generated by a radiation source such that, during the inspection of the at least one part of the vehicle by the inspection radiation, the inspection dose remains substantially equal to a predetermined inspection dose, wherein controlling the inspection dose includes the controller obtaining information representative of a speed of the relative movement of the system and the vehicle during the inspection of the at least one part of the vehicle, and the controller controlling the radiation source, based on the obtained information.

Abstract: A method includes decomposing a training set to obtain a principal component matrix having a plurality of principal component vectors. The method also includes variably rejecting portions of a sample spectrum vector that do not correspond to a selected one of the plurality of principal component vectors by incrementally providing a coefficient indicative of the weighting of the selected principal component vector for selected sub-regions. A corrected spectrum vector can be obtained by excluding certain sub-regions of the sample spectrum vector and corresponding principal component vector, multiplying the sample spectrum vector with the principal component matrix for non-excluded sub-regions, providing a predicted interference vector, and subtracting the predicted interference vector from the sample spectrum vector.

Abstract: An ion transfer tube assembly, a mass spectrometry system, and a method for providing an ion stream to an ion detection device are described that include using an ion transfer tube that provides a coaxial sheath gas flow. In an implementation, an ion transfer tube assembly includes an ion transfer tube for delivering the ion stream, where a sheath gas flows through the ion transfer tube, and where the ion transfer tube receives the ion stream from a first conduit coupled to an ion source; a pump fluidly coupled to the ion transfer tube, where the pump causes the sheath gas to flow through the ion transfer tube, where the ion stream is separated from the ion transfer tube walls by the coaxial sheath gas flow, and where the ion stream is received by a second conduit coupled to the ion detection device.
