Latest Patents

Among Campbell’s most notable inventions is the “Apparatus and method for viscosity measurement.” This innovative apparatus allows for precise determination of changes in the viscosity of fluids. It includes mechanisms for heating a portion of the fluid, determining its rise time and average velocity, and subsequently calculating the viscosity based on these metrics. The design accommodates pre-heating stabilization of the fluid, improving accuracy in measurement. Furthermore, an output signal indicative of viscosity changes can be displayed, such as on an automobile's control panel.

Another groundbreaking invention is his “Method for determining oil viscosity.” This method involves measuring an oil viscosity parameter value while an oil pump circulates oil within an engine lubrication system. The parameter value is then compared against a pre-established look-up table to estimate the oil’s viscosity. This table, created through testing known viscosities at various temperatures and pump speeds, enhances the reliability of viscosity assessments under typical engine conditions.
