Abstract: A first magnetic field generated by a first coil operatively associated with a first portion of a vehicle interacts with at least one conductive element operatively associated with or at least a part of a second portion of the vehicle so as to generate an eddy current in the conductive element, which affects the magnetic field sensed by a magnetic sensor. A conductive element operatively coupled to a portion of the vehicle susceptible to a crash, e.g. a bumper or a door, provides for sensing a crash with the signal from the magnetic sensor. In another aspect, a second magnetic field is generated in the frame of a vehicle by a second coil wherein the frame is adapted so that the reluctance of the associated magnetic circuit is responsive to a crash. Signals from the first or second coils may be used to sense the associated magnetic fields.

Abstract: A method and apparatus are for balancing capacitors in a capacitor bank. Three voltage levels are produced by a reference voltage source, to monitor the state of charge of the capacitors. The capacitor voltage on each capacitor is determined and is compared with the voltage levels. After the charging of the capacitors, normal operation starts when the capacitor voltage reaches the lowest voltage level and before it has reached the central voltage level. A balancing operation starts when the capacitor voltages of all the capacitors have reached the central voltage level, and ends when the capacitor voltage of all the capacitors has once again reached the lowest voltage level. When the lowest voltage level is reached once again, normal operation starts again. A fault is indicated upon reaching the highest voltage level.

Based on a result of the comparison, a function test is performed using the strobe timing to determine a pass/fail result of the semiconductor.

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.
