20120279065 | METHOD OF EXTRACTING BARREL NUTS - The present disclosure relates to a method for removing barrel nuts used for securing a plurality of studs to a turbine blade. Each stud is individually coupled to a respective barrel nut such that each barrel nut is anchored to a root end of the turbine blade. The barrel nut is heated to a predetermined temperature using a controller and a thermocouple. An adhesion between the barrel nut and the turbine blade is overcome and the barrel nut is extracted from the turbine blade. The barrel nut is removed from the turbine blade by connecting an extractor assembly or barrel nut removal device. This is accomplished from an interior surface of a root end of the turbine blade such that this method allows one to remove and replace barrel nuts while the turbine blade remains attached to the hub. | 11-08-2012 |

20140163853 | PLUG-IN CHARGE CAPACITY ESTIMATION METHOD FOR LITHIUM IRON-PHOSPHATE BATTERIES - A method for estimating charge capacity of a lithium iron-phosphate battery pack using data from a plug-in charge event. A laboratory-measured battery pack resistance, which is known to remain constant over a battery pack's life, can be used to determine open circuit voltage from terminal voltage during charging. Actual open circuit voltage after charging can be measured later, after the battery pack has rested for a sufficient amount of time. The two values of open circuit voltage, if taken at points on the battery pack's SOC-OCV curve which have great enough slope, provide two values of battery pack state of charge. By integrating charging current over the time interval between the two open circuit voltage readings, and using the two state of charge values, the battery pack capacity can be determined from the plug-in charge data. | 06-12-2014 |
