Abstract: A calculation method for real-time physical engine enhancement based on a neural network includes: dynamically constructing a multi-layer and multi-surface pre-collision shell according to key concave and convex vertices of an object to be subjected to collision detection; obtaining an initial collision detection correspondence matrix according to the multi-layer and multi-surface pre-collision shell; and setting a collision detection condition, inputting a relevant parameter of the collision detection condition into the neural network for parameter screening, and determining whether a collision condition satisfies a safety condition after the parameter screening. When the collision condition satisfies the safety condition, a collision detection correspondence matrix is not updated. When the collision condition does not satisfy the safety condition, the matrix is updated, and the multi-layer and multi-surface pre-collision shell is reconstructed according to the updated matrix.

Abstract: The invention provides a method and system for Bluetooth-based multi-end-to-multi-end communication, including: obtaining, through a short-term connection-oriented communication, a UUID of a device that needs to receive private data, corresponding the UUID to a private label according to a private label allocation table and storing the UUID in a mapping table within a broadcast host; and looking-up the mapping table, if data to be sent contains private information targeted for a specific receiving object group, then determining whether encryption is required; if encryption is required, then performing dynamical encryption based on the private label and proceeding to a step of Bluetooth broadcast payload sending; and performing corresponding non-private data hosting encapsulation or private data hosting encapsulation for the data to be sent and broadcasting the data.

Abstract: A method, a system and a computer-readable storage medium for simulating clothing comfort and a method for manufacturing clothing. The method for simulating the clothing comfort includes the following steps. A main structure of clothing is established. A clothing entity design is performed on the main structure of the clothing. After the clothing entity design is completed, and sketches are outputted. First of all, the present invention can scientifically simulate the virtual fitting on wearing comfort, and adjust the production of the clothing in simulation to meet the difference of individual comfort requirements. Further, it is intelligent clothing manufacturing. According to a clothing version adjusted in the simulation and combined with the production of human body data to meet the differences in individual clothing manufacturing, it can manufacture fitting and comfortable clothes.
