  • Patent number: 9992855
    Abstract: Rise times and fall times provided by a high voltage generator are controlled to maintain image quality during such scans. The rise and fall times are controlled by first measuring rise and fall times at each transition. Then, a closed-loop controller is used to adjust control parameters of the high voltage generator, based on an error determined from the measurement, to achieve substantially constant rise and fall times. This invention may be based on the implementation of two closed-loop controllers on rise and fall time of fast-kV exposures. As a result, image quality may be improved and system calibration time may be reduced.

  • Patent number: 9986976
    Abstract: Various embodiments include a system and method that enhance performance of an ultrasound system by dynamically changing an impedance of a transmit/receive switch. The system can include a transmit/receive switch and a low noise amplifier. The transmit/receive switch may be configured to switch between a transmit phase and a receive phase of an ultrasound scan. The transmit/receive switch may provide a receive signal communicated from an ultrasound transducer to a low noise amplifier when in the receive phase. An impedance of the transmit/receive switch may be dynamically adjusted by changing a resistance of the transmit/receive switch while the transmit/receive switch is in the receive phase. The low noise amplifier may be configured to amplify the receive signal. In various embodiments, a gain of the low noise amplifier is independent of the resistance of the transmit/receive switch.

  • Patent number: 9990568
    Abstract: A method (100) of constructing a probabilistic graphical model (10) of a system from data that includes both normal and anomalous data includes the step of learning parameters of a structure for the probabilistic graphical model (10). The structure includes at least one latent variable (26) on which other variables (12, 14, 16, 18, 20, 22, 24) are conditional, and has a plurality of components. The method further includes the steps of: iteratively associating one or more of the plurality of components of the latent variable (26) with normal data; constructing a matrix of the associations; detecting abnormal components of the latent variable (26) based on one of a low association with the normal data or the matrix of associations; and deleting the abnormal components of the latent variable (26) from the probabilistic graphical model (10).

  • Patent number: 9987677
    Abstract: A method of forming a component having an internal passage defined therein includes positioning a jacketed core with respect to a mold. The jacketed core includes a hollow structure formed from a first material, an inner core disposed within the hollow structure, and a core channel that extends from at least a first end of the inner core through at least a portion of inner core. The method also includes introducing a component material in a molten state into a cavity of the mold, such that the component material in the molten state at least partially absorbs the first material from the jacketed core within the cavity. The method further includes cooling the component material in the cavity to form the component. The inner core defines the internal passage within the component.
