Abstract: Provided is a bearing arrangement for a wind turbine, including a first portion, a second portion, and a sound wave sensor which is configured to detect a thickness of the second portion, wherein one of the first portion and the second portion is movable relative to the other of the first portion and the second portion. In contrast to known bearing arrangements for wind turbines, the thickness of the second portion which for example is exposed to wear may be actively detected. Thus, the information of the thickness is available at any time. Thus, a demand of an exchange of the second portion can be precisely predicted and determined.

Abstract: A spherical body inspection apparatus including a support arrangement realized to support a spherical body during an inspection procedure; a probe arrangement comprising a plurality of ultrasonic testing probes arranged about the spherical body such that the ultrasonic testing probes target a common test point at the surface of the spherical body; and a displacer for effecting at least one relative rotational displacement between the spherical body and the probe arrangement. Also described is a method of inspecting a spherical body.

Abstract: A spherical body inspection apparatus including a support arrangement realized to support a spherical body during an inspection procedure; a probe arrangement comprising a plurality of UT probes arranged about the spherical body such that the UT probes target a common test point at the surface of the spherical body; and a displacer for effecting at least one relative rotational displacement between the spherical body and the probe arrangement. Also described is a method of inspecting a spherical body.

Abstract: A system and method are disclosed for automatically captioning an electronic demonstration using object properties captured from the operating system. In response to an action that is initiated by a demonstrator, the operating system is queried to obtain the property information for the target object to which the action is directed as well as the parent object of the target object. This property information is then used to generate explanatory captions that are displayed to a user or trainee during the playback of the electronic demonstration.

Abstract: A method for the strengthening of a welded connexion, an element for a tower of a wind turbine, a tower of a wind turbine, and a wind turbine having a welded connexion with modified geometry are provided. The weld seam and/or for the increase of tolerance of a welded connexion in relation to fatigue load which welded connexion joins at least two sections of one component or at least one section of a first component and at least one section of a second component with each other, wherein the geometry of the weld seam and of at least one of the sections, which the at least one section adjoins to the weld seam, is specifically modified by removing welding material from the weld seam and by removing material of the respective section, which material adjoins to the weld seam.

Abstract: A Faraday dose and uniformity monitor can include a magnetically suppressed annular Faraday cup surrounding a target wafer. A narrow aperture can reduce discharges within Faraday cup opening. The annular Faraday cup can have a continuous cross section to eliminate discharges due to breaks. A plurality of annular Faraday cups at different radii can independently measure current density to monitor changes in plasma uniformity. The magnetic suppression field can be configured to have a very rapid decrease in field strength with distance to minimize plasma and implant perturbations and can include both radial and azimuthal components, or primarily azimuthal components. The azimuthal field component can be generated by multiple vertically oriented magnets of alternating polarity, or by the use of a magnetic field coil. In addition, dose electronics can provide integration of pulsed current at high voltage, and can convert the integrated charge to a series of light pulses coupled optically to a dose controller.
