The application provides a urine wetness detection device and method for a care product. The device comprises an absorption body, a collection circuit, a power supply module and an alarm module. The absorption body is used for absorbing liquid. The collection circuit is arranged on the absorption body and sequentially comprises an inner detection layer, a position layer and an outer detection layer. The inner detection layer is provided with a common return line. The inner detection layer and the outer detection layer are respectively formed by at least one detection layer. Each detection layer is provided with a sensing line to correspondingly conduct with the common return line and output a first electric signal to obtain depth information of the liquid when being wetted. The position layer comprises a first conductive layer, a second conductive layer and a sensing line. The first conductive layer and the second conductive layer are respectively provided with conductive lines to form a plurality of intersection points. When the liquid penetrates into the position layer along the thickness direction and simultaneously wets the conductive lines, the corresponding intersection points are conducted and output a second electric signal to collect area information of the liquid. The power supply module supplies power to the collection circuit. The alarm module sends an alarm signal according to the depth information and the area information.

The application discloses a channel scratch depth and width determination method based on speckle domain Gaussian distribution fitting. The method is characterized in that a light guide beam and a camera are cooperated with coherent laser illumination to explore a channel, original laser speckle images in the channel are collected, Gaussian distribution fitting of speckle domains is carried out through drawing a straight line vertical to a scratch in the image, and the depth and width of the target scratch are determined. The scheme provided by the application can be applied to a specific endoscope pipeline diameter, and the depth and width of the scratch can be effectively determined.

This application provides a geological exploration sampling device. After the device is started, the drive assembly drives the core tube drilling section to rotate into the target soil layer. Upon reaching the predetermined depth, the drive stops, and the core tube, along with the fixed support, is pulled out as a whole, allowing the closed sampling chamber and soil sample column to be completely removed. The core tube is placed on a horizontal worktable, and the end of the arc-shaped shell away from the fixed part is released, with the tail of the arc-shaped shell moving away from the drilling section, exposing the previously covered open slot and connecting the sampling chamber to the outside. In the open state, the side of the sample column is exposed, allowing it to be completely removed from the side through the sampling chamber, avoiding sample displacement caused by compression during removal. The side-opening sampling chamber avoids continuous compression of the sample by the tube wall when pushing from the bottom, maintaining the original diameter and stratification of the sample column and preserving the original soil structure to the maximum extent. The side-removal method eliminates vertical movement of the sample due to friction or uneven force during the push rod removal process, ensuring accurate correspondence between the sampling depth mark and the stratum.
