Latest Patents
Miller's latest patents include an Auxiliary Reactor Protection System and a Testable, Fault-Tolerant Power Interface Circuit for Controlling Plant Operations. The Auxiliary Reactor Protection System utilizes redundant trip logic microprocessors that produce partial trip signals, which are then voted on by a pair of voters at the power interface to actuate devices. This system is designed to be straightforward and customizable for individual plants. Additionally, it features an automatic tester and testing method that confirms the accuracy of A/D converters, digital inputs, and verifies all trip and voting logic. The testing subsystem employs a microcomputer to manage the isolation of analog field sensor signals and digital contact signals, ensuring precise monitoring and response.
The Testable, Fault-Tolerant Power Interface Circuit periodically receives test pulses to assess its operation and connections. Voltage and current sensors are integrated to detect testing results and can be utilized for zero-crossing detection when controlling AC powered devices. The circuit performs voting on three input signals to generate a control signal for two power switches, enhancing fault tolerance.
