Title: The Innovations of David T. Cavil
Introduction
David T. Cavil is a notable inventor based in Menomonee Falls, Wisconsin. He has made significant contributions to the field of marine technology, holding a total of 16 patents. His work primarily focuses on enhancing the efficiency and safety of marine propulsion systems.
Latest Patents
Among his latest innovations is a cathodic protection system designed for boats and their propulsion systems. This system utilizes an impressed current cathodic protection method, where the boat's battery connects to a switching type power converter. This converter supplies the anode with higher current at a lower voltage than what is drawn from the battery. The voltage on the anode is regulated to maintain a constant level or to be fixed relative to a reference half cell. Additionally, the voltage drop across a reference resistor can activate an op-amp to turn on a transistor, connecting an alternate power source to the anode. The power converter chip also regulates the voltage across the resistor to prevent excessive voltage on the anode.
Another significant patent is the constant voltage anode system. This innovation involves a marine propulsion unit with a housing exposed to seawater, which is susceptible to corrosion. Cavil's design includes a permanent type anode housing with substantially constant surface characteristics, mounted on the housing and supplied with constant voltage. The design features holes under the anode that allow current to influence and protect the internal passages of the housing.
