Abstract: The present application provides a method for determining a stability of a welding equipment. The method includes acquiring initial welding images of the welding equipment; obtaining at least one welding spot position of each of at least one welded workpiece in each initial welding image by processing the initial welding images; determining a welding center position of each welded workpiece based on the at least one welding spot position of each welded workpiece, and obtaining welding center positions of all welded workpieces comprised in the initial welding images; and determining a stability of welding equipment based on the welding center positions of all welded workpieces. The method determines whether the welding equipment is stable by analyzing the welding images, thereby improving an accuracy of a detection of a stability of the welding equipment.

Abstract: A semiconductor device includes a substrate, a gate structure on the substrate, a source/drain (S/D) region and a contact. The S/D region is located in the substrate and on a side of the gate structure. The contact lands on and connected to the S/D region. The contact wraps around the S/D region.

Abstract: The present invention discloses a method for determining a maximum value of a heart rate data of a user performing a physical activity. Acquire first heart rate data in a first duration of the physical activity performed by the user. Acquire motion data in the first duration of the physical activity performed by the user. Calculate second heart rate data based on the motion data in the first duration of the physical activity performed by the user by a mathematical model and estimate the maximum value of the heart rate data of the user based on a comparison between the first first heart rate data and the second heart rate data.

Abstract: The present invention discloses a method for monitoring an exercise. The method comprises: building up an energy metabolism system having an energy metabolism feature, wherein the energy metabolism feature comprises a first feature factor, wherein the first feature factor is associated with a first biological system being one of a plurality of biological systems of a human body and not associated with the complete human body; building up a mathematical model describing that an energy expenditure depends on at least one exercise-associated parameter based on the energy metabolism feature for the energy metabolism system; estimating the energy expenditure based on the at least one exercise-associated parameter measured in the exercise by the mathematical model of the energy metabolism system; and monitoring the exercise based on the energy expenditure.

Abstract: The present invention discloses a method for monitoring an exercise. Acquire a relationship between a degree of active participation of an organism of a human body and an exercise intensity. Build up an energy metabolism system and build up a mathematical model describing that an energy expenditure depends on the exercise intensity and the degree of active participation of the organism of the human body for the energy metabolism system. Determine the degree of active participation of the organism based on the exercise intensity measured in the exercise by the relationship. Use the exercise intensity and the degree of active participation of the organism to estimate the energy expenditure by the mathematical model of the energy metabolism system. Monitor the exercise based on the energy expenditure.

Abstract: The present invention discloses a method for monitoring an exercise session of a user. The exercise session comprises a first portion and a second portion following the first portion. Provide an exercise record of a previous exercise of the user, wherein the exercise record comprises a first exercise correspondence associated with a first fitness condition of the user. Execute a first exercise scheme to monitor the first portion of the exercise session based on the first exercise correspondence. Execute a second exercise scheme to monitor the second portion of the exercise session based on a comparison of a second fitness condition of the user derived from an exercise data in the first portion of the exercise session and the first fitness condition of the user in the exercise record of the previous exercise.
