A method and system for balancing a rotating device or rotating system having a rotatable member and a shaft attached to the rotatable member, such that balancing is based on system response to simultaneous control actions to place mass, such as for example, fluid, at predetermined locations within

A method and system for balancing a rotating device or rotating system having a rotatable member and a shaft attached to the rotatable member, such that balancing is based on system response to simultaneous control actions to place mass, such as for example, fluid, at predetermined locations within the rotating system or rotating device. Mass can be simultaneously placed at predetermined locations within the rotating system. A system model of measured force and motion parameters can then be calculated in response to simultaneously placing mass at predetermined locations within the rotating system, in order to determine a required correction necessary to place the rotating system in a balanced state. Force can be measured at predetermined locations throughout the rotating system or rotating device in response to simultaneously placing the mass at the predetermined locations within the rotating system or rotating device. Motion can also be measured at predetermined locations throughout the rotating system or rotating device in response to simultaneously placing the mass at predetermined locations within the rotating system or rotating device. A matrix of measured force and motion parameters can be calculated based on independent perturbations of the rotating system. Additionally, an independence or rank criterion may be formulated to determine whether consecutive control actions are different enough from one another toexcite the system in independent directions, thereby forming a model that is sufficiently representative of the dynamics of said rotating system.

The planar lightwave circuit has a first waveguide and a second waveguide that intersect the trench such that optical coupling between the first and second waveguides is dependent upon a presence of a fluid at an intersection of the trench with the first and second waveguides. A mounting base, having a channel and through openings provided therein, has fill tubes disposed in the groove and through openings of the mounting base. A reservoir pedestal having through openings provided therein and bonded to the reservoir pedestal with the fill tubes extending through the through openings therein to form a reservoir substrate. A bubble-forming element is disposed on a first surface of the reservoir pedestal, including patterning a plurality of leads on the first surface and a sealing/bonding ring bonds and seals the planar lightwave circuit and the reservoir substrate to form a reservoir having the bubble-forming element and planar lightwave circuit aligned such that the reservoir is in fluid communication with the fill tubes through the reservoir substrate and the trench in the planar lightwave circuit which is in thermal communication with the bubble-forming element on the first surface of the reservoir pedestal.
