Abstract: Disclosed are a battery connecting piece, a top cover assembly and a lithium battery. The battery connecting piece includes a first current collector and a second current collector, the first current collector is connected to the second current collector in a rotatable manner, the first current collector is configured to be connected to a top cover of a battery, the second current collector is configured to weld a tab of a cell, and an extension direction of a central axis of the second current collector rotating relative to the first current collector is perpendicular to a plane where the top cover is located in a state that the first current collector is connected to the top cover. The battery connecting piece drives the tab to fold more smoothly to prevent the tab from being torn, a bending precision of the tab is improved, and a product consistency is improved.

Abstract: Disclosed are a positive electrode plate, a preparation method therefore and a lithium-ion secondary battery, relating to the technical field of batteries. The positive electrode plate includes a positive electrode current collector and a positive electrode coating layer that is coated on the positive electrode current collector and contains a positive electrode active substance; the positive electrode plate satisfies 0.07<a{circumflex over (?)}3*10*?/?<0.14, a represents the compaction density of the positive electrode coating layer, ? represents the surface density of the positive electrode coating layer, and ? represents the thickness of the positive electrode current collector. While the positive electrode plate satisfies the above formula, the compaction density, the surface density and the current collector thickness of the positive electrode plate may be reasonably configured, such that it satisfies the requirements of the formula 0.07<a{circumflex over (?)}3*10*?/?<0.

Abstract: Techniques for associated narrative based transcription speaker identification are provided. A narrative of an incident is received at a computing device. The narrative describes an incident. An identification of at least one person involved in the incident is extracted from the narrative. The identification includes a specific identifier for the at least one person. Semantic information is extracted from the narrative. A transcript of media capturing the incident is received at the computing device. The transcript includes a generic identifier for at least one speaker whose speech was transcribed. The generic identifier for the at least one speaker whose speech was transcribed is correlated with the identification based on the semantic information. The generic identifier for the at least one speaker in the transcript is replaced with the specific identifier included in the identification.

Abstract: A method and apparatus for creating a composite image of a person is provided herein. During operation, a witness is presented with a plurality of attributes of an individual. A witness selection of an attribute is received from the presented attributes. Images of individuals who were at an incident scene at a time of the incident are received and analyzed to determine images of those individuals with attributes similar to the attribute selected by the witness. The images of those individuals with the attributes similar to the attribute selected by the witness are processed by redacting information from the images to produce a plurality of processed images. The witness is then presented with the plurality of processed images.

Abstract: A flexible substrate, as well as a method of preparing the same, and a display panel are disclosed. The flexible substrate includes: a base substrate; a first light-emitting element and an optical filter disposed on the base substrate. The optical filter is configured to receive the first light beam emitted by the first light-emitting element and filter the first light beam to obtain a second light beam, and configured to enable physical properties of the second light beam to be modulated by a bending degree of the flexible substrate at a position where the optical filter is located.
