The pressure wing and the suction wing of the midspan shroud may be configured so to cooperatively form an interface between installed neighboring ones of the rotor blades within the row of samely configured rotor blades. The interface may include a first one of the pressure wing and the suction wing disposed as an upstream wing and a remaining other one of the pressure wing and the suction wing disposed as a downstream wing. The interface may include the upstream wing and the downstream wing configured as a downstream narrowing step.

  • Patent number: 10132492
    Abstract: A system includes the HRSG having an economizer disposed along a fluid flow path, and a drum disposed along the fluid flow path downstream of the economizer. The HRSG also includes a drum level control module configured to modulate an amount of the fluid provided to the drum along the fluid flow path and a supplemental control module configured to control an amount of the fluid in a different manner than the drum level control module. The heat recovery steam generator also includes a drum level event controller configured to monitor a rate of change of a level of the fluid in the drum. If the rate of change is over a threshold value, a signal goes to the supplemental control. If the rate of change is less than or equal to the threshold value, the signal goes to the drum level control module.

  • Patent number: 10132882
    Abstract: A body coil support structure includes an elongate support member. The elongate support member defines an opening and an examination axis passing through the opening along a length of the elongate support member. The opening is configured to accept an object to be imaged. The elongate support member has a target shape for use during operation of the MRI system, with the elongate support member configured to be subjected to an operational load during operation. In a design state, the elongate support member defines a design shape, with the elongate support member not subjected to the operational load in the design state. In an installed state after installation in the MRI system, the elongate support member defines an operational shape. The elongate support member is subjected to the operational load in the installed state. The operational shape is closer to the target shape than is the design shape.

  • Patent number: 10132850
    Abstract: A system for testing a ground fault detection system in an electric circuit establishes a ground connection between a bus and the ground via an inverter and a load by closing an inverter switch of the inverter and a grounding switch disposed between the load and the ground, determines whether the ground connection is detected, and determines a fault in the ground fault detection system responsive to the first ground connection not being detected by the ground fault detection system. Optionally, a ground fault may be identified by determining three phase voltages provided from each of plural inverters, determining symmetrical components of the three phase voltages for each of the inverters, and identifying a ground fault in one or more of the inverters while powered by the power supply based on the symmetrical components.

  • Patent number: 10132891
    Abstract: A PET-MRI system for imaging an object is provided. The PET-MRI system includes a magnetic resonance imaging sub-system, a positron emission tomography sub-system, an optical sensor, and a data processing controller. The magnetic resonance imaging sub-system includes a surface coil that acquires magnetic resonance signals from the object. The positron emission tomography sub-system acquires PET emissions from the object. The optical sensor detects at least one of a spatial location and a shape of the surface coil. The data processing controller communicates with the magnetic resonance imaging sub-system, the positron emission tomography sub-system, and the optical sensor, and utilizes at least one of the detected spatial location and the detected shape of the surface coil to correct the acquired PET emissions for attenuation.

  • Patent number: 10132889
    Abstract: A system and method for reducing MRI-generated acoustic noise is disclosed. A system control of an MRI apparatus causes a plurality of gradient coils and an RF coil assembly in the MRI apparatus to generate pulse sequences that each cause an echo train to form and acquire blades of k-space data of the subject of interest from the pulse sequences, with the blades being rotated about a section of k-space compared to every other blade. The system control also causes the plurality of gradient coils to generate gradient pulses in each pulse sequence having an optimized gradient waveform that reduces an acoustic noise level generated thereby and causes the RF coil assembly to generate a 180 degree prep pulse subsequent to generation of an RF excitation pulse and prior to generation of a first RF refocusing pulse, the 180 degree prep pulse minimizing echo spacing in the echo train.
