Title: The Innovations of William R Freund, Jr.

Introduction

William R Freund, Jr. is a notable inventor based in Hatfield, PA (US). He has made significant contributions to the field of engineering, holding a total of 7 patents. His work primarily focuses on advancements in flow measurement and voltage conversion technologies.

Latest Patents

Among his latest patents is the "Pulsed DC constant current magnetic flowmeter." This innovative device features a coil driving circuit that controls both the maximum steady-state current and the current rise time through the coils. This design ensures that the performance is independent of the inductance of the specific coil being driven. The maximum current is regulated by a reference voltage derived from a common source, with a second reference voltage utilized in the signal processing chain. This configuration maintains a constant ratio of the reference voltages, allowing the output signal to remain unaffected by the absolute value of the common source.

Another significant patent is the "Crystal stabilized voltage to frequency converter with digital." This system incorporates a voltage-controlled oscillator (VCO) that includes a feedback loop to maintain linearity, temperature stability, and accuracy. The feedback loop generates a fed-back train of pulses with an amplitude equal to a reference voltage, and the duty cycle is proportional to the frequency ratio of the VCO output to a reference frequency. Consequently, the output frequency is made proportional to the input voltage multiplied by the ratio of the reference frequency to the reference voltage.
