Abstract: A method for identifying damage in a component of a wind turbine includes placing a conductive element onto at least one surface of the component of the wind turbine. The method also includes electrically connecting the conductive element into an electrical circuit. Further, the method includes monitoring a status of the electrical circuit to identify the damage in the component. In particular, when the status of the electrical circuit is open, damage is likely present in the component, and when the status of the electrical circuit is closed, damage is unlikely present in the component. Moreover, the method includes transmitting the status of the electrical circuit to a user interface for display.

Abstract: A gear system includes a carrier having a first portion and a separate, second portion and a plurality of pin shafts extending from the first portion of the carrier. Each of the plurality of pin shafts includes a first end and a second end. As such, the first ends are integrally formed with the first portion of the carrier. The first and second portions are arranged on opposing sides of the plurality of pin shafts and are spaced apart such that the first and second portions do not contact each other. Further, the second portion of the carrier defines an end plate that is secured to the second ends of the plurality of pin shafts. The gear system also includes a plurality of gears mounted to the plurality of pin shafts, with each of the plurality of gears arranged so as to rotate around one of the plurality of pin shafts.

Abstract: Systems, devices, and related methods are disclosed for electromechanical transfer printing of 2D materials disposed on one substrate to another. The printing device can be configured to transfer a 2D material from a source substrate to the target substrate by applying a combination of mechanical and electrostatic forces to facilitate electromechanical adhesion between the 2D material layer and the target substrate. Some embodiments of the printing device can effect direct transfer printing of a 2D material from a source substrate to a target substrate without the use of etchants and adhesives.
