  • Publication number: 20260048453
    Abstract: Disclosed is a method for repairing a Babbitt metal bearing shoe by laser cladding, metal plates are placed around a cladding range, thereby assisting in cooling a cladding area and accelerating heat conduction of a base material in the cladding area, and since the metal plates protrude out of a surface of the cladding area to form a step-like shape, thereby avoiding a phenomenon of an undercut of an edge side cladding channel; and by planning an area to be repaired, the cladding area is limited in a range as small as possible, and in addition, the metal plates are arranged around the cladding area for cooling, thereby avoiding a phenomenon of decladding of an original Babbitt metal layer caused by overheating deformation.

  • Publication number: 20260029960
    Abstract: Methods, systems, and devices for logical address indications for accessing sequential data from a memory system are described. The described techniques provide for a memory system to access sequential data associated with non-contiguous logical address ranges based on receiving a read command including information indicating the non-contiguous logical address ranges. For example, the read command may indicate the non-contiguous logical address ranges in an extra header segment (EHS) data field and the memory system may use the indication of the non-contiguous logical address ranges to improve access performance, such as by informing a pre-reading algorithm. In some examples, the memory system may identify that the EHS data field includes a logical address table based on one or more second fields of the read command, such as an EHS length field, an EHS type field, and an EHS sub-type field.

  • Publication number: 20260029936
    Abstract: Methods, systems, and devices for read booster for operational data of a memory system are described. A memory system may access system-related data in a partition via a mapping table stored in volatile memory as opposed to loading multi-level logical-to-physical tables from non-volatile memory. For example, a host system may provide a logical block address (LBA) range of system-related data to be written to the partition using a first command. The memory system may contiguously store physical block addresses (PBAs) corresponding to the LBA range into one or more segments of the partition. To access a given PBA in a segment, the memory system may access one or more parameters stored in the mapping table, such as a starting PBA and size (e.g., in PBAs) for each respective segment.

  • Patent number: 12529501
    Abstract: Aspects of the disclosure relate to an accumulator bottle having a horizontal flow and a u-tube. The u-tube includes (e.g., horizontal) inlet and outlet sections at a common height to minimize a pressure drop for a vaporized refrigerant that passes through the accumulator. Providing the u-tube in a cuboid accumulator with horizontal flow increases the liquid volume capacity of the accumulator while reducing the pressure drop across the accumulator. The u-shape tube also improves oil mixing with the vaporized refrigerant by including an orifice at or near a bottom of the u-tube and within a portion of the accumulator in which liquid oil and/or refrigerant is stored.

  • Publication number: 20250378026
    Abstract: Methods, systems, and devices for transmitting logical-to-physical (L2P) address mapping to a host system are described. A memory system may be configured to determine portions of an L2P mapping that are sequential, and transfer indications of respective starting addresses and a respective size of such sequential mappings. For example, a memory system may be configured to transmit an indication of a starting logical address, a corresponding starting physical address (e.g., a physical address mapped to the starting logical address), and a size of a sequential mapping from the starting logical and physical addresses. In some such examples, search techniques may be adapted at the memory system, at the host system, or both to facilitate address searching with the revised L2P mapping structure (e.g., to leverage indications of starting addresses and lengths of sequential portions), such as implementing aspects of a search tree or hash table.

  • Publication number: 20250377833
    Abstract: Methods, systems, and devices for write buffer management for a memory system are described. The described techniques provide for a memory system to receive data associated with multiple applications being executed concurrently and store the data to portions of a write buffer according to whether the data is sequential or non-sequential. For example, the memory system may receive sequential data for a first application between receiving non-sequential data for one or more second applications, and may partition a write buffer such that the sequential data is stored (e.g., sequentially) within a portion the write buffer and the non-sequential data is stored within a different portion of the write buffer. The memory system may flush portions of the write buffer to multiple-level memory cells once a portion is full, thereby storing sequential data to sequential physical addresses within the memory system.

  • Publication number: 20250362805
    Abstract: Methods, systems, and devices for monitoring memory device access statistics are described. A host system coupled with a memory system may track and analyze user behavior to determine access parameters associated with the user behavior, and may transmit an indication of the access parameters to the memory system. For example, while in an active mode of the host system, the host system may collect and store metadata associated with access commands issued to the memory system. After transitioning to an idle mode of the host system, the host system may analyze the metadata to generate one or more access parameters associated with access statistics of the access commands, and may transmit an indication of the access parameters to the memory system. The memory system may use the access parameters to modify one or more memory access parameters associated with accessing the memory system.
