This invention relates to a positioning device for the width and height of iron core windows. Its structure includes a stacking assembly and an upper positioning assembly fixed to the stacking assembly or to a crossbeam above the stacking assembly. A lower positioning assembly has the same structure as the upper positioning assembly. Both the lower and upper positioning assemblies are used for positioning the iron core. By using the stacking assembly in conjunction with the lower or upper positioning assembly, the height and width of each level of the iron core windows can be positioned. The advantages of this invention are: a simple and reasonable structural design; during the iron core stacking process, the positioning assemblies ensure that the width and height of each level of the iron core windows meet the requirements of the stacking process, effectively guaranteeing stacking quality and improving the consistency of the stacking process; and by adjusting the corresponding sliders, guide rails, support seats, and other parts, it can be applied to the stacking of iron cores of different specifications, demonstrating strong applicability.

The utility model discloses an adjustable curtain rod, belongs to the technical field of curtain accessories, and solves the problems that the mode that the curtain rod is extended to the width of a window by adopting a telescopic structure similar to a Rome rod is unreasonable, and the curtain rod needs to be matched with a roller shutter and a folding shutter to extend the length according to the width of the window. Comprising a main rod, lengthening rods are detachably connected to the two ends of the main rod in the length direction, the rod lengths of the lengthening rods can be increased, the rod lengths of the lengthening rods have a plurality of increasing modes, when the main rod rotates around the central axis of the main rod, the lengthening rods synchronously rotate around the central axis of the main rod, and the transmission ratio of the main rod to the lengthening rods is 1: 1. The rod length increasing mode of the lengthening rod comprises splicing, stretching and retracting, folding and unfolding, combination of stretching and retracting and folding and unfolding, or combination of folding and unfolding and stretching and retracting. The adjustable curtain rod is suitable for the situation that the width of a window exceeds the length of a conventional curtain rod, the length of the adjustable curtain rod can be prolonged to be matched with the size of the window, meanwhile, the adjustable curtain rod is suitable for roller shutters and folding shutters, and adaptability is ensured.

The application relates to a window width and window position automatic generation method and device, computer equipment and a storage medium, wherein the method comprises the following steps: inputting an acquired sample medical image, an initial minimum value of image grayscale and an initial maximum value of image grayscale into a neural network model for prediction, and constructing a loss function of the neural network model based on a prediction result; based on the loss function, the neural network model is iteratively optimized to obtain a target neural network model; a target medical image is input into the target neural network model for prediction to generate a window width and window position. Through the application, the problem that the window width and window position generation efficiency is low and the accuracy is not high due to human factors in the related art is solved, the loss function is constructed by using a prediction result, the training of the target neural network model is completed, and finally the window width and window position are automatically generated based on the target neural network model, so that the influence of human factors is avoided, and the generation efficiency and accuracy are improved.

The invention discloses a CMP end point detection method and system and a dynamic window scaling method.The CMP end point detection method judges an end point based on window logic and comprises the steps that a friction force signal in the grinding process is obtained, and a friction force curve is obtained according to the friction force signal; the window is dynamically adjusted to generate a dynamic window, the dynamic adjustment comprises the step of dynamically adjusting the width of the window in real time by adopting a window width dynamic contraction function, and the window width dynamic contraction function is as shown in the formula (1): W (t) = Wmax * e (-kw * df / dt); wherein W (t) is the window real-time width corresponding to a certain time point t, Wmax is the maximum window width, f in df / dt is the friction force, kw is the shrinkage sensitivity coefficient, and kw is larger than 0; and monitoring the state of the friction curve leaving the window, and if leaving from the right boundary of the window, determining that the grinding end point is reached. The width of the end point area window can be reduced, an end point signal is triggered in advance, and the over-throwing phenomenon is avoided to a great extent.
