Title: Roy E Hunninghaus: Innovator in Electrical Engineering
Introduction
Roy E Hunninghaus is a notable inventor based in Des Plaines, Illinois. He holds a total of 12 patents, showcasing his significant contributions to the field of electrical engineering. His innovative designs have paved the way for advancements in various technologies.
Latest Patents
Among his latest patents is the "Self-powering input buffer." This invention features a first circuit leg that stores a charge, such as in a capacitor, and a second circuit leg with a buffer powered by the first circuit leg. The buffer detects the state of an input with reference to a threshold. A transistor switch is coupled between the circuit legs. If the buffer detects an input voltage higher than the predetermined threshold, it drives the transistor switch ON to conduct current from the first circuit leg to the output. Conversely, if the buffer detects an input voltage lower than the predetermined threshold, it drives the transistor switch OFF to disconnect the first circuit leg from the output. During a voltage dip, the capacitor provides supplemental power as long as the input is above the threshold.
Another significant patent is the "Solenoid driver and method for determining solenoid operational status." This solenoid driver is capable of detecting the operational status of a solenoid, including the position of an armature within a solenoid coil. The operational method involves generating a first solenoid current within the solenoid, which is insufficient to pull the armature into the coil. A comparator circuit continuously monitors the solenoid current and initiates a timer to compute the first current decay time. A second solenoid current is then generated, sufficient to pull the armature into the coil, and the decay times are compared to output the armature position information.
