Abstract: Provided are a separator thickness adjustment device and method, and a winding electrode assembly production system. The separator thickness adjustment device includes: a mounting base; an active roller and a passive roller disposed at the mounting base in parallel to each other, in which each of the active roller and the passive roller is rotatable about its own axis, a gap is formed between the active roller and the passive roller, a separator passes through the gap, and a position of the passive roller relative to the active roller is adjustable to change a size of the gap; a first drive component configured to drive the active roller to rotate about its own axis to move the separator; and a second drive component configured to drive the passive roller to move towards or away from the active roller.

Abstract: A laminating device includes: a plate being bendable, having a resilience characteristic and for bearing the flexible substrate; a supporting base platform for supporting the plate and driving the plate and the flexible substrate on the plate to move; a bending assembly for applying stress to drive the plate and the flexible substrate on the plate to be bent towards a side, facing away from the flexible substrate, of the plate, and for releasing stress to allow the plate and the flexible substrate to rebound; and a fixing fixture for fixing the protective cover plate. The protective cover plate is used to be laminated to the flexible substrate, a shape of the fixing fixture is same as or similar to that of the protective cover plate, the fixing fixture is bent to form an accommodating space, and the protective cover plate is fixed in the accommodating space.

Abstract: A method for selecting a content forwarding node in a vehicle ad-hoc network on the basis of service type, comprising the following steps: calculating a bandwidth occupation proportion factor according to the type of requested content information and a bandwidth occupation situation of a neighboring vehicle which can perform forwarding in a one-hop transmission range; defining a virtual arrival time of a candidate forwarding vehicle to an initial request vehicle according to the distance between the neighboring vehicle and the initial request vehicle and a driving speed of the neighboring vehicle; calculating a forwarding node impact factor according to the bandwidth occupation proportion factor and the virtual arrival time; and selecting a forwarding node according to the forwarding node impact factor.

Abstract: Computer security improvements relating to defenses for real-time account takeover detection using behavior sequence clustering are disclosed. A service provider may utilize a framework having computing operations for detecting and protecting from account takeovers by malicious entities that may utilize compromised accounts. In this regard, the service provider may utilize an account takeover framework and processing pipeline that may identify account behaviors executed by computing devices when using accounts with the service provider. These behaviors may be clustered into behavior sequences that may be verified as sufficiently occurring with other accounts of the service provider. If so, the behavior sequences may be identified as risky and may be used with a real-time detection system to monitor for those behavior sequences. If detected, security operations may be automatically executed to prevent further account takeover risk by malicious entities.

Abstract: According to implementations of the subject matter described herein, there is provided a solution for data embedding and data extraction in images. To perform data embedding, a target region for data embedding is determined from a source image, such as a chart image. Target data to be embedded is converted into a sequence of logical values represented in a predetermined format. Based on the sequence of logical values, image values of one or more image elements in the target region are changed such that the changed image values in the target region can be used to convey the sequence of logical values corresponding to the target data. The variations in image values are within a predetermined range such that no significant data distortion of perception distortion is caused by the data embedding. In a subsequent process, the embedded data can also be easily extracted from the image for use.

Abstract: A programmable receptor complex expressed by an immunocyte, wherein the programmable receptor complex includes a plurality of native or endogenously expressed receptor subunits, wherein the native or endogenously expressed receptor subunits have been engineered or modified to include Fc?RI receptor components, biotin-binding components, or both, and wherein the Fc?RI receptor components and biotin-binding components are operative to bind to target detector molecules that bind to or otherwise interact with predetermined targets.
