Latest Patents
Majcher's latest patents include innovative systems designed to diagnose faults in oxygen sensors. One of his patents, titled "System and method for diagnosing a fault in an oxygen sensor based on engine speed," introduces a system that utilizes an error count module and a sensor diagnostic module. This system increases the error count when the actual air/fuel ratio deviates from the desired ratio and adjusts the count based on engine speed. The oxygen sensor generates a signal indicating the actual air/fuel ratio, and the diagnostic module identifies faults when the error count exceeds a predetermined threshold.
Another significant patent is "System and method for diagnosing faults in an oxygen sensor." This invention features an error period module that determines the duration of time the air/fuel ratios differ. The first oxygen sensor generates a signal indicating the first air/fuel ratio, and the diagnostic module assesses faults when the error period surpasses a predetermined limit.
