摘要： A system that detects vibrations from a mechanical component, such as a disk drive. The system includes an excitation rod, a membrane, and a microphone. During operation, the mechanical component is coupled to the excitation rod which is coupled to the membrane, so that vibrations from the mechanical component are mechanically coupled through the excitation rod to the membrane. The membrane then converts the mechanical vibrations into acoustic waves that are transmitted through a medium. The microphone detects the acoustic waves in the medium and converts the acoustic waves into signals.

摘要： One embodiment of the present invention provides a system that proactively monitors a disk drive to detect an impending disk drive failure. During operation, the system obtains a time-varying electrical signal which is generated by the spindle rotation during operation of the disk drive. Next, the system extracts one or more inferential parameters associated with the spindle rotation from the time-varying electrical signal using a phase-sensitive detection. The system then performs proactive fault detection on the inferential parameters to detect an impending failure of the disk drive.

摘要： A system that facilitates reducing uncertainty in a quantized signal. During operation, the system measures a quantized output signal from a sensor. Next, the system obtains an initial value for an uncertainty interval for the quantized output signal. The system then margins the quantized output signal high by introducing a controlled increase in the mean of the quantized output signal to produce a high-margined quantized output signal. Next, the system measures the high-margined quantized output signal from the sensor. The system then uses information obtained from the high-margined quantized output signal to reduce the uncertainty interval for the quantized output signal.

摘要： One embodiment of the present invention provides a technique for detecting anomalies during operation of a test computer system. Initially, a golden system and the test system are equipped with the same hardware configuration, wherein the golden system has gone through extensive qualification testing and is presumed to be operating correctly. Next, a deterministic load is executed on the golden system, and values for performance parameters from the golden system are monitored while the deterministic load is executing. Similarly, the deterministic load is also executed on the test system, and values for performance parameters from the test system are monitored while the deterministic load is executing. Next, pairwise differences are computed between values for performance parameters received from the test system and values for performance parameters received from the golden system. Finally, change detection techniques are applied to the pairwise differences to detect anomalies during operation of the test system.

摘要： One embodiment provides a system that analyzes telemetry data from a monitored system. During operation, the system periodically obtains the telemetry data as a set of telemetry variables from the monitored system and updates a multidimensional real-time distribution of the telemetry data using the obtained telemetry variables. Next, the system analyzes a statistical deviation of the multidimensional real-time distribution from a multidimensional reference distribution for the monitored system using a multivariate sequential probability ratio test (SPRT) and assesses the integrity of the monitored system based on the statistical deviation of the multidimensional real-time distribution. If the assessed integrity falls below a threshold, the system determines a fault in the monitored system corresponding to a source of the statistical deviation.

摘要： An electronic system includes an accelerometer. A method for excessive mechanical shock feature extraction for overstress event registration and cumulative tracking includes obtaining a sample from the accelerometer. Feature extraction is performed on the sample using empirical mode decomposition (EMD) to produce a plurality of modes. A pattern classifier is utilized for processing the plurality of modes to determine if the sample classifies as a shock event. If the sample classifies as a shock event, a shock event counter is incremented. If the shock event counter reaches a specified count, an indication to a user is generated.
