  • Patent number: 11941301
    Abstract: A technique maintains online access to data stored in a plurality of storage devices during a hardware upgrade in which the plurality of storage devices moves between storage processor enclosures. The technique involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in a first storage processor enclosure. The technique further involves providing, from the plurality of storage devices, online access to the data while the plurality of storage devices is moved from the first storage processor enclosure to a second storage processor enclosure (e.g., transferring each storage devices one by one before triggering a rebuild process). The technique further involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in the second storage processor enclosure.

  • Patent number: 11449406
    Abstract: Techniques to control a storage system involve: determining whether available power capable of being supplied by a supplying apparatus of the storage system is less than power required by the storage system; and in response to a determination that the available power is less than the power required by the storage system, adjusting an operation parameter of the storage system based on the available power so as to match the power required by the storage system with the available power. In this way, the performance of the storage system can be at a higher level while the performance of the storage system can remain stable in a case where power of a processor is limited.

  • Patent number: 11273069
    Abstract: A wearable neck brace uses, for example, only three actuators but provides natural motion of the head and neck. This is achieved despite the fact that the head has six degrees of freedom including 3 translation and 3 rotation. In embodiments, a wearable neck brace actively controls the head of the wearer responsively to commands from a user interface such as an eye tracking input device. In further embodiments, a force-field is generated by actuators to provide assistance and/or training for weak muscles. Spring compensation may be provided for a passive support with flexibility. Encoders may be provided to generate treatment logs to support analysis of a patient's condition or progress or to provide therapy-facilitating (or athletic training-facilitating) feedback to the user.

  • Patent number: 11200109
    Abstract: Techniques involve in response to receiving, from a failure analysis device, a request for obtaining a to-be-analyzed data block in a set of raw data blocks in a data file related to a failure of an operating system, determining a position of the to-be-analyzed data block in a compressed file for the data file, the request comprising a position of the to-be-analyzed data block in the data file. The techniques further involve determining, based on the position of the to-be-analyzed data block in the compressed file, a compressed data block in the compressed file corresponding to the to-be-analyzed data block. The techniques further involve sending the compressed data block to the failure analysis device for analyzing the failure. Accordingly, the time for analyzing the failure may be saved, the amount of data transmission and the resources occupied by decompression may be reduced, and the processing efficiency may be improved.
