    摘要: A system, a device and a method for controlling an operation of a wind turbine (100) based on a wind turbine component workload. The system includes a control device (120) that is configured to actuate a wind turbine component (130). The system also includes a wind turbine controller (205) that is coupled in communication with the control device (120) and configured to determine a workload associated with the wind turbine component (130) based at least in part on one or more actuations of the wind turbine component (130) by the control device (120) within a time period. The wind turbine controller (205) is also configured to calculate an operating threshold value based at least in part on the calculated workload and to operate the wind turbine component (130) by the control device (120) based on the calculated operating threshold value.

    摘要: A membrane electrode assembly (MEA) for a fuel cell comprising a catalyst layer and a method of making the same. The catalyst layer can include a plurality of catalyst nanoparticles, e.g., platinum, disposed on buckypaper. The catalyst layer can have 1% or less binder prior to attachment to the membrane electrode assembly. The catalyst layer can include (a) single-wall nanotubes, small diameter multi-wall nanotubes, or both, and (b) large diameter multi-wall nanotubes, carbon nanofibers, or both. The ratio of (a) to (b) can range from 1:2 to 1:20. The catalyst layer can produce a surface area utilization efficiency of at least 60% and the platinum utilization efficiency can be 0.50 gPt/kW or less.

    摘要: A calibration wafer may bear one or more different mark types to facilitate inspection of a lithography process. A first mark type may be located on the outer peripheral portion of the wafer to indicate the desired boundary of an edge bead removal (EBR) region. A second mark type may be located on an outer peripheral portion of the wafer to indicate the desired boundary of a wafer edge expose region (WEE). A third mark type may indicate the border of a portion of the wafer expected to bear a wafer identification mark. A fourth mark type may be located at the center of the wafer to allow for precise and uniform application of liquid photoresist material to the calibration wafer. The calibration wafer may be employed in methods of rapidly and easily assessing the accuracy of various phases of photolithography processes.

    摘要: A magnetic circuit unit includes a yoke, a magnet positioned on the yoke, a plate on the magnet. The yoke includes a bottom defining a central hole therein, and a wall extending from the bottom. The magnet is positioned on the bottom of the yoke. The plate defines a base coupled to a top surface of the magnet, and a central pole extending from the base and getting through the annular magnet with an end thereof suspended in the central hole of the yoke. Thus, a first magnetic gap is formed between the wall of the yoke and an outer side of the annular magnet, and a second magnetic gap is formed between the central pole of the plate and an inner side of the annular magnet. A speaker using the magnetic circuit unit described above is disclosed.
