Title: The Innovations of Leonard W Jenski

Introduction

Leonard W Jenski is a notable inventor based in Roselle, Illinois, who has made significant contributions to the field of electrical engineering. With a total of six patents to his name, Jenski has developed innovative solutions that enhance the functionality and efficiency of electrical appliances.

Latest Patents

One of Jenski's latest patents is a "System and method for detecting miswiring of an electrical appliance." This invention includes a microprocessor with first and second input connections to sample signals on two different electrical power lines. The microprocessor also features a third input connection for a neutral line. In this embodiment, there is at least one switch that controls the flow of electrical power into a load, which is managed by the microprocessor. The microprocessor is designed to compare the signals sampled at the first and second input connections to determine if the electrical appliance has been wired correctly.

Another significant patent is the "Adaptive defrost control circuit with relay power saving feature." This invention provides a defrost heater relay control circuit that reduces power consumption during a de-energized mode of operation. The relay drive circuit utilizes a series-connected capacitor to introduce a phase shift in the AC current waveform, significantly reducing the real power dissipated in the circuit when the defrost heater control relay is de-energized. This innovation effectively shorts out the relay drive voltage without generating heat due to real power dissipation through the switched circuitry that disables the relay.
