Title: Alan McCall: Innovator in Liquid Sensing and Tire Monitoring Technologies
Introduction
Alan McCall is a notable inventor based in Antrim, Ireland. He has made significant contributions to the fields of liquid sensing and tire monitoring technologies. With a total of 2 patents to his name, McCall's innovations reflect his expertise and dedication to advancing engineering solutions.
Latest Patents
One of McCall's latest patents is a "System and method for sensing the level and composition of liquid in a fuel tank." This innovative liquid sensing system utilizes an RF signal applied to a series-resonant circuit. The coil of the resonant circuit is strategically placed near a fuel tank, allowing electromagnetic radiation to propagate into the fuel space. The fuel acts as an electrical load to the resonant circuit, which changes the resonant frequency and/or the Q of the circuit based on the volume of fuel and its electrical properties. The system monitors changes in electrical parameters, such as voltage across a resistor, to output values indicative of the fuel's level and composition.
Another significant patent is for the "Determination of wheel sensor position using shock sensors and a wireless solution." This remote tire monitoring system includes a control unit and multiple tire monitors that can be mounted on vehicle wheels. Each tire monitor features motion sensors, such as shock sensors, which provide position information based on their signals. This design eliminates the offset created by centrifugal force in traditional accelerometers, simplifying the tire monitor's design.
