  • Patent number: 7376499
    Abstract: A system and related method for monitoring the state of health of sensors in an integrated vehicle stability control system. In one embodiment, the system determines whether a yaw rate sensor, a lateral acceleration sensor or a hand-wheel angle sensor has failed. The system uses a plurality of models to generate estimates of the outputs of the sensors based on the actual sensor measurements. Residuals are generated as the difference between the measured value and each of the estimates for the particular sensor. The residuals are compared to a threshold to determine whether a fault flag will be set for each residual. The threshold for the hand-wheel angle sensor is an adaptive threshold because it does not have physical redundancy. If the fault flags for the residuals for each sensor have a particular pattern, then a fault is output for that sensor.

    Abstract: A method and system for detection and remediation of sensor degradation in a monitoring device is disclosed. The method comprises defining or selecting a monitor signal, and setting at least one monitor signal range bounded by one or more upper thresholds and one or more lower thresholds for detecting degradation and/or shut-off. At least one measured sensor output signal is selected from the monitoring device that is within the monitor signal range. A predicted proxy sensor signal is generated concurrently with the measured sensor output signal in real-time. The predicted proxy sensor signal is blended with the measured sensor output signal when shut-down is impending or close to being recovered from. The predicted proxy sensor signal is used in place of the measured sensor output signal when the monitor signal crosses an upper or lower shut-off threshold during a shut-off period.

  • Patent number: 7305317
    Abstract: A joint approach of out-of-range detection and fault detection for power plant monitoring. The method initially determines whether a sensor is an independent sensor or a dependent sensor. If the sensor is an independent sensor, then an operating range is established for each independent sensor. A reading from each independent sensor is then compared with the operating range that has been established. If the reading is out-of-range, an alarm may be activated. If the reading is not out-of-range, then this reading is used to determine an expected operating range for each dependent sensor. A reading from each dependent sensor is then compared with the predicted operating range. Again, if the reading from the dependent sensor is out of the expected range, an alarm may be sounded.

  • Patent number: 7147366
    Abstract: The rationality of a measured temperature of transmission fluid is assessed by comparing it to an engine coolant temperature. The rationality assessment is enabled when the ambient air temperature is reliably determined and deemed normal, a sufficient soak condition is confirmed, and the measured temperature, the engine temperature and the ambient air temperature are all within prescribed ranges. The rationality assessment monitors the ambient temperature relative to the initial engine temperature during the assessment period, and the assessment is disabled if the ambient air temperature deviates from the initial engine temperature by more than a calibrated value.

  • Patent number: 7076389
    Abstract: One embodiment of the present invention provides a system that validates sensor operability in a computer system. During operation, the system perturbs the computer system with an excitation, wherein the excitation may be physical or software-based. The system then receives a number of responses to the excitation through sensors in the computer system, wherein each response is represented as a value of a variable which may vary with time. Next, the system compares the received responses with a set of reference responses gathered from properly functioning sensors in a reference computer system. The system then determines from the comparison whether the sensors in the computer system are operating properly.

  • Patent number: 7065465
    Abstract: A multi-sensor data fusion system and method provides adaptive weighting of the contributions from a plurality of sensors in the system using an additive calculation of a sensor reliability function for each sensor. During a predetermined tracking period, data is received from each individual sensor in the system and a sensor reliability function is determined for each sensor based on the SNR (signal-to-noise ratio) for the received data from each sensor. Each sensor reliability function is individually weighted based on the SNR for each sensor and a comparison of predetermined sensor operation characteristics for each sensor and a best performing (most reliable) sensor. Additive calculations are performed on the sensor reliability functions to produce both an absolute and a relative reliability function which provide a confidence level for the multi-sensor system relating to the correct classification (recognition) of targets and decoys.

  • Patent number: 7065466
    Abstract: System for testing attenuators by a flatness and standing wave ratio tests which includes a vector network analyzer (VNA) adapted to be coupled to a device under test (DUT) and which provides an input stimulus signal for the DUT and, when certain conditions are satisfied, receives an output signal from the DUT, and a calibration receiver adapted to be coupled to the DUT via a down-converter. When certain conditions are satisfied, the output signal from the DUT is sent to the calibration receiver (through the down-converter to be possibly modified thereby depending on the testing frequency). A signal generator provides a local oscillator (LO) signal for the down-converter. A control unit is connected to the instruments and embodies software which analyzes the testing conditions, i.e., the attenuator value being tested, and selects whether the network analyzer or the calibration receiver will measure the output signal from the DUT.
