Abstract: Disclosed are a battery and an electronic device. The battery includes a film housing, a first cell, a second cell and a partition plate. The film housing is provided with an accommodating cavity, a first accommodating groove adapted for the first cell is formed on a side of the partition plate. The first cell is placed in the first accommodating groove, the second cell is placed on another side of the partition plate, the first accommodating groove and the second cell are disposed side by side in the accommodating cavity, and the first cell and the second cell are separated by the partition plate.

Abstract: Disclosed are a separator and a battery cell. The separator is used for being winded together with an electrode plate to prepare a battery cell, and the separator includes: a first section, a second section and a third section which are sequentially arranged in a length direction of the separator. A width of the first section is less than a width of the second section, and/or, a width of the third section is less than the width of the second section.

Abstract: Methods, systems, and devices for memory performance evaluation using address mapping information are described. A memory system may write a data file associated with a range of logical block addresses to a first set of blocks in a set of memory dies. The memory system may then determine, for a memory die of the set of memory dies that stores a portion of the data file, a quantity of read operations for reading the portion of the data file. The memory system may determine the quantity of read operations based on address mapping information that maps logical block addresses associated with the datafile to physical addresses. After determining the quantity of read operations, the memory device may use the quantity of read operations to determine a performance metric associated with the data file and the first set of blocks.

Abstract: Human-machine interface for required time of arrival (RTA) constraint negotiation. Embodiments present critical RTA information and results of associated data calculations to the pilot in a concise and informative manner using a dialogue box with intuitive graphical displays. Embodiments present critical RTA information to assist a pilot in negotiating the RTA constraint with air traffic controllers, accepting the clearance, and having confidence in the system that it will achieve the defined RTA constraint.
