  • Publication number: 20250133639
    Abstract: Disclosed are a charge and discharge balancing circuit and an LED drive system, which include multiple charge and discharge branches, each of which includes a charge circuit and a discharge circuit. The charge and discharge branches are each connected to an energy storage device. The charge circuits are connected to a charging power supply, and the discharge circuits are connected to a load. Each charge and discharge branch determines whether to charge the connected energy storage device according to a voltage signal of the charging power supply and a voltage signal of the connected energy storage device, and determines whether to discharge to the connected load according to a voltage signal at a load connection terminal and the voltage signal of the connected energy storage device. The voltage signal at the load connection terminal is the maximum value among the voltages transmitted to the load by each branch.

  • Publication number: 20210011834
    Abstract: Example service upgrade management methods, apparatuses, and storage medium are provided. One example method includes creating a gray release policy and a gray traffic distribution rule. A gray traffic distribution status can then be controlled. The gray release policy, the gray traffic distribution rule, and the gray traffic distribution status can then be delivered to a gray traffic distribution device, where the gray release policy, the gray traffic distribution rule, and the gray traffic distribution status are used by the gray traffic distribution device to control a flow direction of a service message.

  • Patent number: 10683459
    Abstract: Provided are a liquid-phase hydroisomerization system and a process therefor and use thereof. The system comprises a gas-liquid mixer (3), a hydroisomerization reactor (4) and a fractionating column (6). An oil product and hydrogen are mixed as a liquid hydrogen-oil mixture, and are introduced into the hydroisomerization reactor for a hydroisomerization reaction, and after being fractionated, a target product is led out. A supplemental hydrogen-dissolving inner member is provided at least between a group of two adjacent catalyst bed layers in order to supplement hydrogen to the reactants. The process cancels a circulating hydrogen compressor, has a simple process flow, and can be applied to the production of a lubricant base oil by the hydroisomerization of a lubricant raw material or the production of a low freezing point diesel by the hydroisomerization of and the reduction in the freezing point of a diesel raw material.

  • Patent number: 9624545
    Abstract: Methods and compositions disclosed herein generally relate to methods of treating eosinophilic esophagitis (EE) and eosinophilic disorders by providing or enhancing a diagnosis of EE and eosinophilic disorders. In particular, the invention relates to obtaining a sample from a patient, then quantifying from the sample an amount of one or more microRNAs (miRNAs) associated with EE, wherein an altered level of the miRNA correlates with a positive diagnosis of EE. An EE diagnosis can then be provided or enhanced, based upon the quantifying step, and an appropriate treatment can be administered to the patient. The invention further relates to diagnostic kits, tests, and/or arrays that can be used to quantify the one or more miRNAs associated with EE, as well as treatments developed to up-regulate or down-regulate one or more miRNAs and/or their downstream pathways relevant to EE or asthma. The invention further relates to the use of IGF1 and IGF1R inhibitors for the treatment of EE and eosinophilic disorders.
