Abstract: A method of diagnosing sensor faults for a heating, ventilation and air conditioning system includes the steps of creating a component model for a specific component within the system. The component model is created through the use of commonly available manufacturing data. Data within the system is input into the component model and compared to calculated and predicted values that are also calculated using the identical component models. Differences between the calculated and actual values is determined and compared to a threshold difference value. If the difference exceeds the threshold value, then a fault is detected. The specific type of sensor fault is determined using probability distribution analysis. Each type of sensor fault produces a different type of statistical deviation from normal distribution.

Abstract: A testable digital delay line that uses XOR gates as delay elements is provided. The use of XOR gates enables independent control of each input to the multiplexer. With test inputs that enable each delay element, the multiplexer inputs can be assigned any value during test, thus giving the delay line very robust pattern fault coverage. The XOR gate may consist of three current limiting inverters. A reference voltage generator generates constant voltages between a source voltage, bias voltages, and ground. These constant voltages decide the amount of current through the current limiting inverters. Selecting a different set of reference voltages programs a different current flowing in the current limiting inverters. This programmable current causes a programmable unit delay to be introduced by each XOR gate delay element.
