An apparatus for generating electrical energy includes at least one generator connected to a drive device. This involves the creation of a standardized ontology for genetic, phenotypic, clinical, pharmacokinetic, pharmacodynamic and other data sets, the creation of a translation engine to integrate heterogeneous data sets into a database using the standardized ontology, and the development of statistical methods to perform data validation and outcome prediction with the integrated data. A thrust washer engages an inner surface of the lubricant passage to retain a bearing assembly on each trunnion. In this case, it is recommended to discontinue monitoring the space or to discard any result of this monitoring already obtained at least until no parasitic signal portions are detected in a repeated evaluation of the second received signal.
