20080306705 | APPARATUS AND METHOD FOR IDENTIFYING A DEFECT AND/OR OPERATING CHARACTERISTIC OF A SYSTEM - An apparatus and methods for identifying a defect and/or an operating characteristic of a system being monitored (and/or one or more of the system's components) are described. In an embodiment, orthogonally related data monitored by two or more detectors may be fused to determine whether a component of a system is defective and/or malfunctioning. Additionally or alternatively, data from a first detector may be determined to be accurate using non-orthogonally related data outputted by a second detector. Both types of determinations may be made with minimal or no false indications, which lowers the cost of operating the system being monitored. Embodiments of the invention may also be configured to forecast and/or prevent accidents and/or damage to the system being monitored by predicting whether a defect and/or a malfunction will occur | 12-11-2008 |
20100071469 | Synthesized synchronous sampling and acceleration enveloping for differential bearing damage signature - A system for detecting differential bearing damages includes a synthesized tachometer that generates a tachometer signal corresponding to the race speed difference of a bearing assembly such that the bearing damage speed difference dependency can be eliminated and the damage features can be enhanced. The system also includes acceleration enveloping in the cycle domain to further enhance the damage signatures. | 03-25-2010 |

20120025526 | SYSTEM AND METHOD FOR MONITORING WIND TURBINE GEARBOX HEALTH AND PERFORMANCE - A system and method are provided to monitor the health and performance of a wind turbine gearbox. A plurality of sensors coupled to the wind turbine gearbox provide input to a controller. The controller generates output information that includes performance and health information of the wind turbine gearbox based on the input received from each of the sensors. | 02-02-2012 |
20120029838 | SYSTEM AND METHOD FOR MONITORING A WIND TURBINE GEARBOX - A system and method are provided to monitor the health of a wind turbine gearbox. The system includes a plurality of sensors coupled to the wind turbine gearbox and a controller coupled to the plurality of sensors. The controller is configured to acquire vibration information from a vibration sensor, acquire a tachometer signal, convert the tachometer signal and the vibration information into a cycle domain signal, and perform an order analysis on the cycle domain signal, the order analysis providing information that identifies potential and actual damage within the wind turbine gearbox. | 02-02-2012 |
20120131877 | FRICTION DAMPING BOLT CONNECTION FOR A WIND TOWER LATTICE STRUCTURE - A wind turbine lattice tower structure includes a plurality of structural members connected together to define an open lattice tower, with the structural members including vertical leg members and diagonal braces extending between the vertical leg members. Pairs of the diagonal braces form cross braces having an intersection point therebetween. A damping bolt connection assembly is provides at the intersection point of the cross braces and is configured to attach the cross braces together at the intersection point while providing for relative movement of each individual cross brace along a defined longitudinal section of the other respective cross brace. | 05-31-2012 |
