3results about How to "Achieve retention" patented technology

This utility model provides an automated mineral sample dispensing and retention system, relating to the technical field of mineral sample dispensing and retention processes. It includes a conveying unit for conveying original sample boxes and wide-mouth sample bags respectively; a weighing unit for weighing the dispensed and retained samples; a placement unit for placing the dispensed and retained samples; and a moving unit for picking up the original sample boxes and wide-mouth sample bags from the conveying unit and sequentially moving them to the weighing and placement units. This system boasts a high degree of automation, enabling automated dispensing of mineral samples by number, retention of remaining samples, and traceability of remaining sample quality. It ensures the accuracy of mineral sample dispensing and retention information, and allows for fully automated batch processing, benefiting the occupational health and safety of workers, improving work efficiency and quality. It effectively overcomes the technical shortcomings of existing technologies that require manual operation at each stage, have low automation levels, and suffer from significant human error in sample management.

A multi-barrier coupled treatment process for organic complexed heavy metals in wastewater from battery cathode material production is disclosed, relating to the field of wastewater treatment. The method involves: 1. Adjusting the pH of the wastewater to 3.0-4.5; 2. Adding iron salt and peracetic acid to an oxidation reaction tank; 3. Achieving primary removal of heavy metals through neutralization and precipitation after oxidation; 4. Adjusting the pH of the wastewater back to 6.0-6.5; 5. Passing the wastewater sequentially through a primary adsorption unit and a secondary adsorption unit. This invention utilizes the low bond energy characteristics of PAA and the synergistic oxidation advantages of multiple free radicals to solve the bottleneck problems of incomplete complex breaking, large sludge production, and narrow pH application range in traditional methods. After treatment by this invention, the total nickel concentration in the effluent is less than 0.05 mg / L, and the total cobalt concentration is less than 0.02 mg / L, consistently exceeding the limits of the "Emission Standard of Pollutants for Battery Industry" (GB 30484-2013), demonstrating broad industrial application prospects.

This invention discloses a cascaded detection method for dynamic allocation of computing power in video surveillance based on prior knowledge, specifically including the following steps: S1, data acquisition and generation of domain of interest; S2, dynamic allocation of computing power; S3, cascaded detection; S4, alarm evidence collection and feedback. This invention relates to the field of intelligent video analysis and resource scheduling technology. This cascaded detection method for dynamic allocation of computing power in video surveillance based on prior knowledge generates domains of interest based on task text and divides camera channels into active / dormant states accordingly. This reduces the inference frequency in non-interested periods and areas, thereby reducing ineffective computing power usage. Through two-level cascaded inference of "full-image human body localization + fine recognition within the ROI," it can reduce interference from complex backgrounds in wide-angle scenes and improve the accuracy of identifying the violation attributes of small targets. Through the export of evidence fragments from a circular cache and the return of manual confirmation, alarm evidence retention can be achieved.
