Abstract: Various methods and systems are provided for an x-ray imaging system. In one example, a method for decelerating a rotor of an x-ray tube of an imaging system includes controlling and/or monitoring a speed and position of the rotor, passing the rotor through a first position where a force exerted on the rotor, is less than Earth's gravitational pull, the force due to a combination of gravity and radial acceleration, and initiating a predefined deceleration profile to decelerate the rotor to a halt when the x-ray tube passes through the first position.

Abstract: An intracavity laser absorption infrared spectroscopy system for detecting trace analytes in vapor samples. The system uses a spectrometer in communications with control electronics, wherein the control electronics contain an analyte database that contains absorption profiles for each analyte the system is used to detect. The system can not only detect the presence of specific analytes, but identify them as well. The spectrometer uses a hollow cavity waveguide that creates a continuous loop inside of the device, thus creating a large path length and eliminating the need to mechanically adjust the path length to achieve a high Q-factor. In a preferred embodiment, the laser source may serve as the detector, thus eliminating the need for a separate detector.
