  • Patent number: 12038374
    Abstract: Methods and systems for determining characteristics of fluids are described. A method involves illuminating a portion of a fluid by emitting light having an emission spectrum spanning at least from an infrared band to an ultraviolet band, and producing an output signal by receiving the light upon being scattered by the fluid using an optical detector. A controller may select a target sub-band of the emission spectrum based on information associated with the fluid, and may further determine a characteristic of the fluid using at least a portion of the output signal associated with the target sub-band of the emission spectrum. Alternatively, or additionally, a controller may apply an operator to the output signal, and may further determine the characteristic of the first fluid by applying a machine learning model to a result of the operator as applied to the first output signal.

  • Patent number: 12023193
    Abstract: An X-ray imaging system using multiple pulsed X-ray source pairs in-motion to perform highly efficient and ultrafast 3D radiography is presented. The sources move simultaneously on arc trajectory at a constant speed as a group. Each individual source also moves rapidly around its static position in a small distance, but one moves in opposite direction to the other to cancel out linear momentum. Trajectory can also be arranged at a ring structure horizontally. In X-ray source pairs each moves in opposite angular direction to another to cancel out angular momentum. When an individual X-ray source has a speed that equals to group speed but an opposite linear or angular direction, the individual X-ray source is triggered through an external exposure control unit. This allows the source to stay relatively standstill during activation. 3D data can be acquired with wider view in shorter time and image analysis is real-time.
