  • SYSTEMS AND METHODS FOR DETERMINING MECHANICAL WEAR IN A CRYSTAL PULLER
    Publication number: 20230304893
    Abstract: A detection system includes a loadcell connected to a gear and motor of a crystal puller apparatus to measure force applied to the gear in a time domain. The data is analyzed though a Fourier transform to obtain data in the frequency domain. The frequency domain data includes an amplitude which corresponds to mechanical wear of the gear. The time domain data is compared against a threshold amplitude to determine if the gears have mechanical wear such that preventative maintenance can be performed on the motor.

  • Reconstruction hard disk array and reconstruction method for to-be-reconstructed hard disks therein including comparing backup data with an access timestamp of first, second and third hard disks
    Patent number: 10831601
    Abstract: A reconstruction method based on a hard disk array comprises determining whether at least one damaged hard disk among a plurality of hard disks of the hard disk array has been replaced by at least one to-be-reconstructed hard disk, and writing a backup data corresponding to the at least one damaged hard disk into the at least one to-be-reconstructed hard disk according to a mapping table and information of the at least one damaged hard disk.

  • RECONSTRUCTION HARD DISK ARRAY AND RECONSTRUCTION METHOD BASED ON HARD DISK ARRAY
    Publication number: 20190354439
    Abstract: A reconstruction method based on a hard disk array comprises determining whether at least one damaged hard disk among a plurality of hard disks of the hard disk array has been replaced by at least one to-be-reconstructed hard disk, and writing a backup data corresponding to the at least one damaged hard disk into the at least one to-be-reconstructed hard disk according to a mapping table and information of the at least one damaged hard disk.

  • HARD DISK ARRAY AND METHOD FOR RECONSTRUCTING THEREOF
    Publication number: 20180181467
    Abstract: A method for reconstructing hard disk array is disclosed. In the method, at least one to-be-fixed hard disks among a plurality of hard disks of the hard disk array are determined. Then, instead of reconstructing and re-writing the hard-disk array, writing into the at least one to-be-fixed hard disks a data of the at least one to-be-fixed hard disks according to a mapping table is performed, the data corresponds to a backup data of the plurality of hard disks.
