Title: The Innovative Contributions of Ronald E Honganen
Introduction
Ronald E Honganen is a notable inventor based in Campbell, CA (US), recognized for his contributions to pump technology. With a total of 4 patents, he has made significant advancements in systems that enhance the efficiency and reliability of pumps.
Latest Patents
One of his latest patents is a maintenance reminder system for a pump. This system is designed to be coupled to the pump or its control system, determining the volume of fluid pumped. In this embodiment, a piston pump is utilized, where piston strokes are counted and converted to the total volume of liquid pumped. The system maintains a database for each maintenance item, containing threshold values and the total volume pumped since the last maintenance. When the total volume exceeds the threshold, a maintenance reminder is displayed, allowing the user to access information regarding which item requires service. The database is updated after the service is performed.
Another significant patent is an apparatus for controlling a pump to account for the compressibility of solvents. This invention provides a method for controlling a dual piston pump in a liquid chromatography system. It ensures a constant flow rate and maintains the desired solvent composition despite changing conditions of compressibility. The control system employs a computer that measures the time taken for the pump shaft to move through an overlap region during the pump cycle. This time is compared to a stored time for incompressible solvents, allowing for the derivation of a correction factor for compressibility, which is then used to control the flow rate and solvent composition.
