  • Method for simulating an N1 and N2 speed vibration composite input for development and/or model based testing of engine control hardware and embedded software
    Patent number: 11474494
    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.

  • Speed sensor identification
    Patent number: 9140718
    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.
