  • Patent number: 10047722
    Abstract: The present disclosure is directed to a method for controlling a wind turbine having a rotor with a plurality of rotor blades mounted thereto based on a spatial wind speed distribution. The method includes monitoring, via at least one sensor, one or more operating conditions of the wind turbine. The method also includes determining a rotor azimuth angle of the wind turbine. In addition, the method includes determining, via a physics-based model, at least one individual wind speed for one or more of the rotor blades of the wind turbine based on the one or more operating conditions and the rotor azimuth angle. The method also includes determining a spatial wind speed distribution of the wind turbine based on the at least one individual wind speed. Thus, the method further includes controlling the wind turbine based on the spatial wind speed distribution.

  • Publication number: 20180202977
    Abstract: A method and system for inspecting a rail profile include using ultrasonic phased arrays. Determined anomalies, such as material flaws like volumetric defects and cracks, in a fluid-immersed rail profile are detected by employing one or more phased array probes located proximate the rail profile. Electronic delays and beam steering and focusing can be employed to tailor the inspection to the rail geometry.

  • Publication number: 20180182632
    Abstract: Methods and systems for using a time-series of spectra to identify endpoint of an etch process. One method includes accessing a virtual carpet that is formed from a time-series of spectra for the etch process collected during a training operation. And, running a fabrication etch process on a fabrication wafer, such that while the fabrication etch process is performed portions of a carpet defined from a time-series of spectral is generated for the fabrication etch process. Then, comparing the portions of the carpet of the fabrication etch process to the virtual carpet. End pointing is processed for the fabrication etch process when said comparing indicates that a desired metric has been reached for the fabrication wafer. In one example, said portions of the carpet include a current frame of captured spectra and at least one previous frame of captured spectra.

  • Publication number: 20150330947
    Abstract: A method and a device for the near-surface, non-destructive inspection by means of ultrasound of a rotationally symmetric workpiece having a diameter that changes from section to section are provided. The method and device are based on the insonification of an ultrasonic test pulse into the workpiece at a defined insonification angle and the subsequent recording of an ultrasonic echo signal from the workpiece. Echo signals that trace back to a near-surface region ROI of the workpiece are identified and evaluated. Then, a graphic representation of the surface of the workpiece is generated.

  • Patent number: 6898734
    Abstract: The present invention provides a method, computer program product, input/output device, and computer system for stress testing the I/O subsystem of a computer system. An input/output device capable of engaging in repetitive direct memory access (DMA) transfers with pseudo-randomized transfer parameters is allowed to execute multiple DMA transfers with varying parameters. In this way, a single type of device may be used to simulate the effects of multiple types of devices. Multiple copies of the same I/O device may be used concurrently in a single computer system along with processor software to access the same portions of memory. In this way, false sharing, true sharing may be effected.
