Latest Patents

One of Douglass's latest patents is the "Distributed Battery Monitoring System." This innovative system is designed to measure the complex impedance associated with an arrangement of batteries or fuel cells in an energy storage system. It includes a controller, a current measurement device, and voltage measurement devices. The current measurement device is shared by the cells for measuring a test current provided to the cells, while the voltage measurement devices are coupled across corresponding cells. The controller determines the respective complex impedance of the cells using complex voltage and current measurements, compensating for any asynchrony between the measurement devices via a DC isolated bus.

Another significant patent is the "Isolated Communications Interface." This invention provides a method and interface for serial communication, featuring a differential input/output with multiple input/output nodes for receiving serial interface signals. The interface includes a transmitter that drives a twisted pair cable and a receiver with a window comparator. This serial communications interface transmits and receives data independently of a reference clock and is galvanically isolated from other interfaces.
