摘要： Some embodiments of the present invention provide a system that detects the presence of constrained motion in one or more components in a computer system. First, a vibrational spectrum of the computer system is monitored while the computer system operates. Then, the vibrational spectrum is analyzed using a pattern-recognition model to detect constrained motion in one or more components in the computer system, wherein the pattern-recognition model classifies the vibrational spectrum as indicating constrained motion or as not indicating constrained motion.

摘要： Some embodiments of the present invention provide a system that characterizes the performance of a disk drive at frequencies in a set of frequencies in a frequency range. First, the disk drive is vibrated at each frequency in the set of frequencies, one frequency at a time. During this process, a disk drive performance metric is monitored. Next, the performance of the disk drive is characterized by determining the parameter related to acceleration due to the vibrations for each frequency at which a disk drive performance metric degrades by a predetermined amount from a baseline.

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.

摘要： One embodiment of the present invention provides a system that generates a vibration profile for a rotational device in a computer system. During operation, the system sequentially sweeps a rotation speed of a rotational device over a range of rotation speeds. While driving the rotational device at each rotation speed, the system collects a time-domain vibration signal produced by the rotational device and subsequently computes a frequency spectrum of the time-domain vibration signal. In this way, the system generates a set of frequency spectra associated with the range of rotation speeds. Next, the system combines the set of frequency spectra to generate a composite vibration profile for the rotational device.
