Abstract: The present disclosure provides a game monitoring method, a game monitoring apparatus, a device and computer-readable storage medium. An image or video collection for a game area is performed, a state of a designated object within the game area is determined based on at least one collected frame, and a detection for the game area is stopped in response to determining that the designated object is in a first state and resumed in response to determining that the designated object is switched from the first state to a second state. Through the above solution, scenarios in which a game host performs some specific operations on the designated object, e.g. a game prop withdrawing device, can be identified automatically based on an image or video of the game area, and the detection for a game area can be stopped or resumed when these scenarios begin or end, which achieves monitoring the game more intelligently.

Abstract: A cold and/or hot compress system, comprising a water bag (101), an air bag (102), a water circulation assembly (2) in fluid communication with the water bag (101) and a pneumatic assembly (3) in fluid communication with the air bag (102).

Therefore, during the delivery of a cooling or heating therapy, the independent pneumatic assembly (3) can be driven by an air pressure waveform defined by parameters pre-stored in a control panel (402) to cause the water bag (102) to apply cold/hot compress to a region of interest of a patient's body. Independent water and air circulation paths in the system avoid interference between water and air flows therein, allowing the system to applied more stable compress with minimized pressure errors. Moreover, a more constant water flow rate and a more uniform temperature distribution across the surface of the water bag are achievable.

The parent model is then identified from the received description, and a description of the set of parameters for generating the parent model is retrieved. Using the description for the target model and the parent model, a pipeline for generating the target model is generated. Finally, the pipeline is executed to generate the target model.
