Abstract: The present application is suitable for use in the technical field of computers, and provides a smart diagnosis assistance method and terminal based on medical images, comprising: acquiring a medical image to be classified; pre-processing the medical image to be classified to obtain a pre-processed image; and inputting the pre-processed image into a trained classification model for classification processing to obtain a classification type corresponding to the pre-processed image, the classification model comprising tensorized network layers and a second-order pooling module. As the trained classification model comprises tensor decomposed network layers and a second-order pooling module, when processing images on the basis of the classification model, more discriminative features related to pathologies can be extracted, increasing the accuracy of medical image classification.

Abstract: The present disclosure relates to the field of intelligent driving, and discloses an information fusion method. The method is applied to intelligent vehicles, and includes: obtaining a plurality of sensing information sets, where each sensing information set includes information about at least one target, and different sensing information sets come from sensing systems of different devices; and when at least two sensing information sets in the plurality of sensing information sets include information about a first target, fuse the information about the first target in the at least two sensing information sets to obtain fused information about the first target. In the method, information about a same target in a plurality of sources is fused to make the fused information about the target more accurate and effective.

Abstract: A pump head of a diaphragm booster pump, a diaphragm booster pump, a water treatment device and a method of operating a pump head. The pump head includes: a piston chamber, including a booster chamber arranged on an inner wall of the piston chamber; and a diaphragm, the booster chamber formed through enclosing the diaphragm, and the booster chamber radially expanding or compressing. The movement of two eccentric wheels with a phase difference of 180° in an eccentric assembly drives balance wheels of a balance wheel assembly to move oppositely. During rotation of the eccentric assembly, eccentric forces counteract each other, and the moment keeps balanced. The balance wheel assembly includes big small balance wheels, which are a first small balance wheel, the big balance wheel and a second small balance wheel in sequence, and the eccentric assembly drives the balance wheel assembly to swing eccentrically through a bearing.

Abstract: The present application provides a flexible LED electronic screen, relating to the technical field of LED screens. During practical applications, by employing an FPC flexible circuit board and upper and lower shells made of PU or PVC materials, the present application prepares an LED electronic screen which can be bended and folded arbitrarily. An interface circuit arranged at two ends of the FPC flexible circuit board is used for splicing of an LED electronic screen, and users may perform splicing as needed, without limitation on length. In addition, the flexible LED electronic screen prepared according to the present application is easy to paste and move, with a wide field of application.

Abstract: A battery malfunction detection method includes: applying a preset number of vibration signals with different frequencies to a battery to be detected through a vibration generation device; collecting a response signal of the battery to be detected through a response collection device, where the response signal includes the preset number of vibration response amplitudes of the battery to be detected; determining whether the battery to be detected is malfunctioning according to the response signal.

Abstract: Embodiments of the disclosure provide a warning method and an apparatus for a driving risk, a computing device and a storage medium. In an embodiment, driving behavior data of a driver in a first time period is obtained, and a correspondence between a quantity of occurrences of preset driving behaviors of one or more drivers and a quantity of an actual occurrence of preset scenarios to the one or more drivers while driving is obtained. Based on a quantity of actual occurrences of the preset driving behaviors of the driver, indicated in the driving behavior data of the driver, and the correspondence, it is predicted a target quantity of times the driver is predicted to encounter one or more preset scenarios in the first time period, and warning information is generated based on the target quantity of times.
