  • Publication number: 20050027586
    Abstract: A method for generating a financial report indicative of estimated turbine maintenance costs is provided. The method includes receiving, at a database, turbine operational history data and turbine inspection data from a user for a pre-identified turbine, receiving, at the database, turbine replacement part costs, turbine part repair costs, and vendor service costs associated with the pre-identified turbine, inputting a pre-determined turbine operational forecast into the database, analyzing turbine maintenance information including at least one of turbine operational history data, turbine inspection data, replacement part costs, part repair costs, vendor service costs, and turbine operational forecast, and automatically generating a financial report including at least one schedule of turbine maintenance events and costs associated with each event based on the turbine maintenance information analysis.

  • Patent number: 6527130
    Abstract: The invention provides a load measurement in a crane hoist system. A parameter adaptation process uses a model of the system in order to measure the lifted load. A controller monitors hoist speed and hoist torque feedbacks that are input into the model and processed using a filter, as well as a previously determined load value. The model adapts automatically to determine the weight of the lifted load.

  • Patent number: 5443566
    Abstract: The invention is for the electronic control of the sway of a suspended load from a crane. The natural frequency .omega..sub.n of a simple pendulum is used to estimate the velocity and displacement of the suspended load, and a signal representative of measured load displacement is used to drive the estimated load displacement to the measured load displacement and modify the estimated velocity.
