Latest Patents
Among his latest innovations are two noteworthy patents. The first is a "Circuit interrupter with digital trip unit and automatic reset." This invention features a microprocessor-based trip unit that includes multiple output control lines and a power supply. The design incorporates interlock means to maintain the output control lines in an inactive status for a specific time after the power supply is energized. This allows the operating power to stabilize before the microcomputer takes control. Additionally, an automatic reset circuit is included to ensure the microcomputer program counter resets unless a specific pulse pattern is received.
The second patent is for a "Circuit interrupter with solid state digital trip unit and positive." This device includes a microcomputer-controlled trip unit with a numeric display and LED indicators. It provides post-tripping indications of the cause of the trip and the trip current value. The design ensures reliable operation during power-up conditions and allows for accurate long delay and ground fault tripping operations.
