Title: Leonard W. Hardesty: Innovator in High-Voltage Technology

Introduction

Leonard W. Hardesty is a notable inventor based in King George, Virginia, recognized for his contributions to high-voltage technology. He holds 2 patents that showcase his innovative approach to engineering challenges. His work primarily focuses on developing advanced electrical devices that enhance performance and efficiency.

Latest Patents

One of Hardesty's latest patents is for a high-performance pulse generator. This device is a compact Marx-type generator capable of producing a high-voltage burst of pulses with risetimes of less than 10 nanoseconds at repetition rates up to 10 kHz. High-pressure hydrogen switches are utilized as the switching elements to achieve high rep-rate performance. The small coaxial design ensures low inductance and fast risetime, making it suitable for applications as a high-rep-rate high-voltage trigger generator or a high-voltage pulse source capable of producing up to 1 MV pulses at high repetition rates.

Another significant patent is for an apparatus and method of measuring the intrinsic time constant of liquids. This invention, termed a 'taumeter', directly measures the intrinsic time constant τ of liquids by impressing a predetermined voltage level between a pair of electrodes immersed in the liquid. The taumeter measures the time it takes for the voltage to decay from a predetermined value to another. Comparator logic produces a gate pulse that is used to count zero crossings of a highly accurate system clock, determining the intrinsic time constant of the liquid.
