Latest Patents
One of Yu's latest patents is titled "Method and apparatus for interface dual modular redundancy - Controller triple modular redundancy." This invention enhances reliability in systems with duplicate controllers that serve peripheral units. Both controllers are designed to detect faults in themselves and in each other. When a peripheral unit suspects a faulty active controller, it can request a switch to a different active controller. A voting circuit processes votes from the controllers and the active controller switch signal from the peripheral units to determine which controller should be active. The signaling paths between the controllers, which convey votes and active controller information, are duplicated. These signals utilize oscillating signals of different frequencies to convey information effectively.
