  • Publication number: 20180153404
    Abstract: A method of monitoring a patient includes operating each of one or more wireless sensing devices to measure a physiological parameter from a patient and wirelessly transmit a parameter dataset, and receiving the one or more parameter datasets from the one or more wireless sensing devices. The method further includes calculating a patient condition index based on the one or more parameter datasets, wherein the patient condition index is an indicator of stability of the one or more physiological parameters. A measurement interval is then assigned for each wireless sensing device based on the patient condition index, and each wireless sensing device is operated according to the respective measurement interval.

  • Patent number: 9988936
    Abstract: A shroud assembly for a gas turbine engine includes a shroud, hanger, and a hanger support mounted adjacent to a plurality of blades. The hanger can have an interior chamber defining a cooling circuit with a particle separator located within the interior chamber. The particle separator can have an inlet for accepting a flow of cooling fluid, such that a the flow of cooling fluid separates into a major flow and a minor flow carrying particles or particulate matter along the minor flow into a particle collector comprising at least a portion of the particle separator. Particles become constrained to the minor flow and pass into the particle collector, while the major flow is separated into the remaining area of the interior chamber to remove the particles from the flow of cooling fluid passing into the interior chamber.

  • 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.
