Latest Patents
One of his latest patents is a "Method for detecting broken valve stem." This invention provides an indication and alarm of a possible failure in a fluid control valve stem, plug, or seat within a process control system that utilizes a microprocessor-based valve positioner. The system monitors drive pressure, drive signal, and valve position feedback. If a significant change in these parameters is detected, a second series of detection steps is initiated to compare the current set point to a stored test cycle derived set point. This process alerts the operator to any changes that may indicate a damaged valve component requiring inspection.
Another significant patent is the "Maintenance interface device for use in a process control network." This device is designed for use in a digital, loop-powered process control network and includes an interface for a two-wire input/output port of a field device or communication media. It features control logic to determine the operational status of the field device or communication loop and a display for showing this status. The device can perform functionality tests on various devices within a process control network, ensuring their operational integrity.
