Abstract: A surgical stapler and a control method therefor. A control part of the surgical stapler is used to acquire a real-time drive current value and a jump current average value of a drive part; then, determine the difference value between the drive current value at a current moment and the drive current value at a previous moment; compare the difference value to the jump current average value, if the difference value is greater than the jump current average value, control the drive part to stop working. Thus, an operator does not have to determine by his or herself whether anastomosis action is completed before operating the surgical stapler, thereby increasing surgical efficiency.

Abstract: The present disclosure provides a non-contact fatigue detection system and method based on rPPG. The system and method adopt multi-thread synchronous communication for real-time acquisition and processing of rPPG signal, enabling fatigue status detection. In this setup, the first thread handles real-time rPPG data capture, storage and concatenation, while the second thread conducts real-time analysis and fatigue detection of rPPG data. Through a combination of skin detection and LUV color space conversion, rPPG raw signal extraction is achieved, effectively eliminating interference from internal and external environmental facial noise; Subsequently, an adaptive multi-stage filtering process enhances the signal-to-noise ratio, and a multi-dimensional fusion CNN model ensures accurate detection of respiration and heart rate.

The mating island defines a mating face and plural passageways. The passageways receive conductive terminals and penetrate through the mating face. A soft cushion is set inside the waterproof cap. The connector body includes a collar portion. The collar portion is higher than the mating face and forms an entrance cavity around the ring groove. When the cap covers the connector body, the soft cushion penetrates into the entrance cavity to press and seal the mating face.

Abstract: Disclosed are a poly dopamine film and a preparation method and application thereof. The polydopamine film is loaded with silver sulfadiazine, and the preparation method achieves in-situ synthesis of si sulfadiazine on a conventional polydopamine film by microwave irradiation. In the method, the sulfadiazine is not dissolved in conventional aqueous ammonia, which has the following advantages: firstly, preventing the polydopamine film from being corroded by the aqueous ammonia; secondly, protecting mucosa such as eyes and nasal cavities of workers from stimulation and corrosion of the aqueous ammonia; and thirdly, avoiding the environmental problem caused by pungent odor and fumes emitted from high-concentration aqueous ammonia. In the method, without using the catalyst trifluoromethanesulfonic acid or trifluoromethanesulfonic salt, not only is the loading of silver sulfadiazine increased, but also the safely performance can be further improved.

Abstract: A method and system for finding and efficiently evaluating and selecting a wellbore path that accounts for placement rules and the presence of existing wells. A topological representation of the connected paths is created and managed. The topological representation may be generated as a pre-computed database of space information that represents the locations of existing wells and accounts for restrictions such as anti-collision and the parameters, including geological and drilling equipment parameters. Using such a representation, the design of a wellbore path may be completed quickly and more efficiently. The topology may represent all connected space for a section of the subsurface. This topological representation may be used to evaluate all possible paths from the starting point (surface location, tie-in point for a sidetrack, tie-in point for replanning, etc.) to the target and enable selecting the path that meets the conditions and is optimized for the existing constraints.
