Latest Patents

One of Zarriello's latest inventions is a battery health monitor (BHM). This device operates as a battery-mountable full-spectrum alternating current (AC) impedance meter. It facilitates the monitoring of a battery's state-of-charge and state-of-health. The BHM is designed to monitor various electrical parameters, such as impedance, of a battery. It includes a current sink that is coupled to the first terminal, configured to sink an oscillatory current. This current causes the battery to produce an oscillatory voltage that is equal to or less than the DC operating voltage of the battery. Additionally, a voltage sensor is included to sense the oscillatory voltage at the first terminal.

Another significant patent is the cathodic protection design method, which utilizes numerical techniques like the finite element method (FEM). This method models the current and voltage distribution in concrete structures, such as bridges. It predicts the geometric arrangement of groundbeds and ideal locations for electrical contacts in relation to the bridge's geometry and rebars. A magnetic sensor is employed to sense the magnetic field generated by the cathodic protection current. The current is mapped by placing the magnetic sensor on or above the concrete surface, allowing for uniform distribution across the entire structure.
