Abstract: An electric oil pump comprises a stator assembly and an electronic control panel assembly which are electrically connected. The electronic control panel assembly comprises an electronic component. The electric oil pump further comprises a conductive pump housing and a conductive member that electrically connects a reference ground layer of the electronic control panel assembly and the pump housing. The above arrangement facilitates reducing electromagnetic radiation of the electronic control panel assembly, thereby reducing interference of the electromagnetic radiation of the electronic control panel assembly on the electronic component and/or other external devices.

Abstract: Disclosed is a state estimation method for a power battery formation process based on convex space filtering, belonging to the technical field of power battery manufacturing. The method performs state estimation on a time delay system by a filtering method, and an iterative replacement method is provided for converting the state quantity at a time k to the state quantity at a time k?h and subsequent items, so as to combine time delay items, thereby avoiding the problem that the dimension is increased when a state matrix A and a state matrix Ah of a time-delay state quantity are subsequently combined into a new state matrix, and reducing the computation complexity and computation time in subsequent computations. Moreover, the estimation accuracy is also improved to a certain extent because of the cancellation of the same items in the iterative replacement.

Abstract: The present invention relates generally to the technical field of integrated circuit mask design, and more particularly to a method, an apparatus and an electronic device for photolithographic mask optimization of joint optimization of pattern and image. The method includes steps: inputting the main pattern; dividing edges of each main pattern into short edges, and regarding the short edges as a first variable for optimizing the main pattern; generating same or similar assistant feature sample points around same or similar main patterns, and regarding the assistant feature sample points as a second variable for optimizing the main pattern; and forming an objective function with the first variable and the second variable as optimization variables. The rules for generating assistant feature sample points around each main pattern are consistent, which are not limited to specific locations of the main pattern and ensures the consistency of final results for optimizing each main pattern.
