Abstract: Methods, systems, and apparatuses related to source address memory management are described. For example, a controller can be coupled to a memory device to select a source block, a destination block, and a metadata block. The controller can store metadata indicative of an address of the source block in the metadata block. The controller can perform a memory management operation to transfer data from the source block to the destination block.

Abstract: Methods, systems, and devices for adaptive block mapping are described. In some examples, a first superblock and a second superblock may be established across one or more dice of a memory device. The superblocks may each include one or more blocks from a plurality of planes of a memory die. In some examples, the second superblock may include at least one bad block (e.g., defective block) in addition to one or more good blocks (e.g., non-defective blocks). The memory device may receive a command for writing data in a first mode and may write a first subset of the data to the first superblock in the first mode, a second subset of the data to the second superblock in the first mode, and one or more blocks associated with the second superblock in a second mode. Additionally or alternatively, the memory device may receive a second command for writing data in the second mode and may write the data to the first superblock in the first mode.

Abstract: An audio playing method, an audio playing apparatus, and a storage medium are provided. The method includes the following. When a first Bluetooth earphone receives a first audio packet transmitted by a terminal, packet locking is performed on the terminal. When the first Bluetooth earphone and a second Bluetooth earphone complete synchronization of information for an initial audio packet, packet unlocking is performed on the terminal. The first Bluetooth earphone and the second Bluetooth earphone play synchronously a target audio from the initial audio packet according to multiple audio packets received.

Abstract: The disclosure discloses a paper money identification method and device. The paper money identification method comprises: obtaining entire grayscale image data of the paper money to be tested; dividing the entire grayscale image of the paper money to be tested into a plurality of areas; comparing the feature value of each area with feature value of a corresponding area in a paper money template to judge whether the two compared areas are matched; counting the number of unmatched areas of the paper money to be tested; judging whether the number of the unmatched areas is greater than a second preset threshold; and determining that the paper money to be tested is the altered money when the number of the unmatched areas is judged to be greater than the second preset threshold. By the disclosure, the accuracy of identifying the altered money is improved.

Abstract: The disclosure discloses a method and device for controlling a composite scanning device, and a composite scanning system. The composite scanning system includes: a composite scanning device and a host which includes: an application module configured for performing a first capability setting on the composite scanning device, obtaining the scanned image data from the composite scanning device after the first capability setting, and processing the scanned image data in a first TWAIN session state; and a configuration module configured for performing a second capability setting on the composite scanning device according to the processing result of the application module in the first TWAIN session state. By the disclosure, the efficiency of capability setting in the composite scanning system which is compatible with TWAIN protocol can be improved.
