Abstract: The present invention provides a method for creating a process change detection algorithm. An evolutionary computing technique is applied to at least one process dataset containing at least one known process change. The evolutionary computing technique will generate a process state function (or a scaling coefficient set for use with an existing process state function) that optimizes detection of the known process changes. The generated process state function or coefficients can then be applied thereafter to future datasets (either in real-time or after processing) to detect process changes.

Abstract: The present invention provides a control adapter for use with an existing dual lever lawn tractor that allows an operator to use a single hand in operating tile dual lever lawn tractor. Existing dual lever lawn tractors require an operator to use one hand on each lever to operate the lawn tractor. The control adapter of the present invention is operatively connected to the first control lever and to the second control lever of the dual lever lawn tractor which allows the operator to use a single hand in operating the dual lever lawn tractor.
