Latest Patents

One of his latest inventions is the "Multi-circuit direct current monitor with Modbus serial output." This innovative device consists of multiple Hall Effect current sensors mounted on a printed circuit board. These sensors are designed to sense the direct current (DC) flow from power-generating devices such as solar arrays. The output from the Hall Effect sensors is connected to an analog to digital (A/D) converter, which in turn is linked to a microprocessor. The multi-circuit direct current monitor continuously tracks instantaneous and average current values for each circuit, as well as the total instantaneous and average current for all active circuits. It provides continuous communications via Modbus RTU and includes alarm outputs if one or more circuits deviate from the average output by a user-defined threshold for a specified period. This feature is crucial for detecting failed or underperforming power output devices.
