  • Publication number: 20250253509
    Abstract: A liquid injection device includes a liquid injection assembly, a first driving mechanism, and a carrying mechanism. The liquid injection assembly includes a liquid injection body and a liquid injection head arranged on the body. The first driving mechanism is configured to drive the liquid injection assembly to move. The carrying mechanism is configured to carry a replaceable wiping member. The carrying mechanism cooperates with the first driving mechanism, so that the liquid injection head comes into contact with a different position on the replaceable wiping member, and then the liquid injection head is wiped.

  • Patent number: 11919884
    Abstract: A method for preparing voriconazole L-camphorsulphonate and voriconazole. The method for preparing voriconazole L-camphorsulphonate comprises: method 1: dissolving (2R,3S)/(2S,3R) isomer mixture and L-camphor sulphonic acid in water and acetone, and performing crystallisation filtration to obtain voriconazole L-camphorsulphonate; method 2: (a) dissolving a mixture of isomer mixture and L-camphor sulphonic acid in a first solvent and then performing crystallisation filtration; or (a?) dissolving L-camphorsulphonate of the isomer mixture in a first solvent and then performing crystallisation filtration; (b) concentrating the filtrate obtained in step (a) or (a?) into a solid; and (c) dissolving the solid obtained in step (b) in a second solvent and performing crystallisation filtration to obtain voriconazole L-camphorsulphonate. Adjusting the resolution solvent effectively reduces production costs and facilitates recycling of the resolution solvent.

  • Patent number: 11847670
    Abstract: Systems, devices, and methods are described herein for improving inventory management. As used herein, “inventory” refers to digital space at an inventory providers webpage at which content can be delivered. The disclosed techniques utilize reinforced machine learning and an offline training process to train various models with which a content request corresponding to the inventory can be classified according to historical requests and a selection process identified for the request (e.g., a direct or an indirect selection process). If an indirect selection process is chosen, the content request may be optimized for that process utilizing additional machine learning models trained using reinforced machine learning and the offline training process. The disclosed techniques enable the inventory provider to optimize content selections according to a preferred objective. The training operations are performed offline, in a training system configured to simulate the run time environment.

  • Patent number: 11284453
    Abstract: There is provided a fast paging procedure in which a master device repeatedly sends the paging message to a slave device using predetermined channel frequencies, wherein a selection of the predetermined channel frequencies is not calculated or predicted from the slave's Bluetooth device address. When the master device receives a slave page response message at one frequency among the predetermined channel frequencies, the master device transmits an FHS packet to the slave device at the same frequency in which the slave page response message was received.
