Title: Innovations by Dennis Keith Mull

Introduction

Dennis Keith Mull is an accomplished inventor based in Concord, OH (US). He has made significant contributions to the field of technology with a total of two patents to his name. His work primarily focuses on innovative sensing technologies that enhance manufacturing processes.

Latest Patents

One of Mull's latest patents is the "Edge Detector." This invention features a capacitance measuring circuit that includes a sensor electrode and a reference electrode, which are spaced apart to allow material positioning between them. A first and second polarity voltage source charge the sensor electrode, while a switch controller manages the charging and discharging of a capacitor. The charge on the capacitor, after being charged and partially discharged, represents the capacitance between the sensor and reference electrodes. This charge is utilized to measure the material's position relative to the electrodes. Additionally, the measuring circuit incorporates a system parasitic controller to account for parasitic capacitance within the circuit.

Another notable patent is the "Carpet Position Sensor." This device detects the undulating pile tuft edge position of a carpet during processing in a carpet-making machine. It achieves this by sensing attenuated light passing through the carpet's primary backing material, allowing for precise determination of the tuft edge position. The sensor signals are digitally filtered to produce an average pile edge position signal, which controls actuators for the backing material guide rolls. This ensures that the carpet is centered for aligned entry into the machine's tenter and that the secondary backing material is applied accurately.
