Abstract: A system and method for generating input signals for an electronic engine control module includes a first waveform generator that is configured to generate a simulated first speed signal that is representative of a first speed and a vibration modulating signal that is representative of the first speed, a second waveform generator that is synchronized with the first waveform generator is configured to receive the vibration modulating signal and to generate a simulated second speed signal that is representative of a second speed and a simulated composite vibration voltage signal, and a voltage-to-charge converter that is configured to receive the simulated composite vibration voltage signal from the second waveform generator and to generate a simulated composite vibration charge signal that simulates a speed/vibration composite signal from an accelerometer.

Abstract: A method of initializing speed sensors in a rotational system is used determine a sensor spacing. An indexing feature is identified at each of two locations on an outer circumference of a wheel path corresponding to two speed sensors, as well as the speed of the wheel. The spacing of the sensors is then determined.

Abstract: A system for reducing message dropout rate in a communication system is provided. Message dropouts occur during transportation of isochronous datasets across a plesiochronous boundary. The system includes a first processing element configured to operate in response to a first clock signal at a first clock speed. The system further includes a second processing element configured to operate in response to a second clock signal at a second clock speed, different from the first clock speed. The second processing element is operably connected to the first processing element by a data bus. The first processing element and the second processing element are configured to indicate a fault when no dataset is received during a processing interval. If two different datasets are received within the same processing interval one of the two datasets is dropped.
