Title: The Innovations of William C. Wolffe
Introduction
William C. Wolffe is an accomplished inventor based in Valley Forge, PA. He holds 2 patents that showcase his innovative contributions to technology. His work primarily focuses on fluid level sensing and coin mechanisms, demonstrating his versatility and expertise in engineering.
Latest Patents
One of Wolffe's latest patents is a fuel system that features a self-compensating fluid level sensor. This invention includes a dual array of capacitive sensors on a dielectric substrate, forming multiple sensor pairs. The design incorporates multiple signal detection circuits, including comparators, to compare the capacitance of different sensor pairs. This internal capacitance comparison allows the sensor to adjust for variations in the dielectric of the fluid being measured, as well as for manufacturing and material differences that can affect capacitive sensing. Additionally, this passive level sensor can provide extra circuitry to offer more information about the liquid, such as its composition.
Another significant patent by Wolffe is a coin mechanism that utilizes a piezoelectric film sensor. This mechanism includes a coin debounce device that interacts with the coin as it travels along a designated path. The piezoelectric film sensor detects micro-movements of the coin debounce device when a coin is inserted. This detection triggers a transition from a quiescent mode to an active mode, allowing for coin recognition while reducing overall power consumption.
