Abstract: An automatic nitrogen filling and replacing device for hydrogen production by water electrolysis, which includes a nitrogen inlet and a pipeline. The nitrogen inlet is communicated with a check valve through the pipeline, the check valve with two flowmeters through the pipeline, and the pipeline with the check valve. The flowmeters is branched into two paths and communicated with an electromagnetic valve through the pipeline. The electromagnetic valve is communicated with a pressure reducer through the pipeline, the pressure reducer on the left side with an oxygen separator through the pipeline, and the pressure reducer on the right side with a hydrogen separator through the pipeline. Alkaline liquid is filled in the lower parts of the insides of the hydrogen separator and the oxygen separator.

Abstract: Systems and methods for scalable shared memory among networked devices comprising IP addressable memory blocks is disclosed. The disclosed systems and methods comprise a communications network, one or more memory lending devices, each comprising one or more allocated and/or available uniformly sized blocks of memory remotely lendable over the communications network, wherein each of the one or more blocks of memory are uniquely addressable over the communications network using an Internet Protocol (IP) destination address. The systems and methods comprise further comprise at least one memory borrowing device comprising one or more remote blocks of memory allocated (loaned) thereto, wherein the at least one memory borrowing device is configured to individually access each of the one or more remote blocks of memory allocated thereto over the communications network using a unique Internet Protocol (IP) destination address.

Abstract: Techniques for managing disks involve: determining a current usage parameter associated with each of a plurality of disk sets, the current usage parameter indicating usage associated with a capability of each of the plurality of disk sets, and the capability comprising at least one of the following: a number of permitted accesses per time unit and a number of permitted writes per time unit; imbalance degree associated with the plurality of disk sets, the first imbalance degree indicating a difference in the current usage parameters of the plurality of disk sets; and causing data in at least one disk slice of a first disk set to be moved to a second disk set of the plurality of disk sets, so as to lower down the first imbalance degree. In this way, a better balance can be achieved among performances of respective disks after adjustment.

Abstract: Techniques for managing disks involve determining, based on a parameter related to a capability of a plurality of disks, a reference capability parameter for each of the plurality of disks. In addition, the techniques involve determining a used capability parameter for each of the plurality of disks. Moreover, the techniques involve determining from the plurality of disks a first disk to be adjusted, a used capability parameter of the first disk exceeds a reference capability parameter of the first disk. The techniques further involve causing data of at least one disk slice in the first disk to be moved to a second disk of the plurality of disks, such that a difference between the used capability parameter of the first disk and reference capability parameter of the first disk is below a predetermined threshold. Accordingly, a balanced operation among respective storage disks can be achieved.
