  • Patent number: 11422608
    Abstract: Techniques involve: if it is determined that a power supply level of a processing unit in a normal mode in a computer system is lower than a threshold level, determining the remaining power of a battery backup unit in the computer system; and if it is determined that the remaining power is higher than the threshold power, causing the battery backup unit to supply power to the processing unit to maintain the processing unit in the normal mode. Accordingly, the performance of the computer system can be optimized and stabilized without increasing the hardware cost of the computer system or changing the power supply capability of the computer system, and the user experience of users using the computer system can be improved.

  • Publication number: 20220236884
    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.

  • Publication number: 20220236908
    Abstract: Techniques involve obtaining, at a first network interface card coupled with a first device, information related to a plurality of data blocks to be written to a second device, the information including sizes of the plurality of data blocks and a plurality of destination addresses in a memory of the second device where the plurality of data blocks will be written. The techniques further involve generating a write request for the plurality of data blocks based on the information, the write request indicating at least the plurality of destination addresses and the sizes of the plurality of data blocks. The techniques further involve sending the write request to a second network interface card coupled with the second device, so that the plurality of data blocks are written to the plurality of destination addresses. Such techniques reduce the number of communications thus improving system performance and reducing hardware resource consumption.

  • 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.

    Abstract: A pixel arrangement structure may include a plurality of repeating units (100). Each of the plurality of the repeating units (100) may include a first sub-pixel (01) being at a center point of a virtual hexagon and second sub-pixels (02) and third sub-pixels (03) being alternately arranged at vertices of the virtual hexagon. Virtual hexagons of adjacent repeating units may share one common side as well as two sub-pixels on the common side.

  • Publication number: 20210216427
    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.
