The present invention discloses a pressure vessel apparatus with sensing identification function, comprising a pressure vessel body and an an identification tag. The pressure vessel body has a concave container located on its surface. The identification tag is located in the concave container, comprising a record IC and a communication unit. The record IC is used for recording the status information of the pressure vessel body. When the reading device reads the identification tag, and thus provides an identification signal such that the communication unit transmits the status information to the reading device to verify whether the lifetime of the pressure vessel apparatus was expired. Moreover, a sensing unit is applied for detecting the varying status of the content in the pressure vessel body, and such information is provided to the reading device as a judging reference for content filling and the pressure reading of the pressure vessel apparatus, in order to improve the safety of the pressure vessel apparatus.

The embodiment of the invention discloses a cache management method and a cache management device. Through the technical scheme, when data is about to be replaced, if access exists in a cache period (i.e., the number of accessing times is greater than 0), the data is added into a cache again; data with different numbers of accessing times are added to different positions; data with many numbers of accessing times are added to difficult-to-replaced positions; and the data accessing frequency is more considered so that more frequently accessed data are more difficult to be replaced. In addition, by aiming at the same total accessing quantity, data with long-term uniform accessing can more permanently stay in the cache than data with the short-term focused accessing, so the data more suitable for an accessing mode of the cache is remained in the cache. Further, when data stored in an adjusted page returns to the cache again, the number of accessing times is reset, so the number of accessing times in a certain time only generates once gains, and the retention of data in the cache caused by accumulated accessing quantity of the data due to mass accessing in a short time is prevented.

A tool-less hub is provided for hunting blinds and tent structures. Poles with particularly-shaped protrusions are insertable in and removable from the tool-less hub. The protrusions allow the pole to enter the tool-less hub at a particular angle, but once rotated to a different angle, the pole is secured with the hub. And thus, no tools are required to change out a broken pole from the hub. In addition, the tool-less hub may comprise a location for an accessory mount, which may comprise a plurality of bodies that articulate about each other. Accessories such as cameras, lights, game calls, scent dispensers, firearms, shelves, hooks, etc. may be interconnected to the accessory mount, and the articulating bodies may position the accessory in any number of locations and orientations.

The invention discloses a composite pressing block type phase change heat storage gas-solid hydrogen storage reactor. A whole structure is a cylindrical shell; the exterior of the reactor is coated with a thermal insulation layer; the interior of the reactor is loaded with a hierarchical porous tray convenient to dismount, the hierarchical porous tray is used for placing a composite pressing block, and the top of the reactor is fixed with hydrogen inlet and outlet pipelines. The top of the reactor is sealed with a large flange, and for preventing a powdered composite pressing block from entering the inlet and outlet pipelines, filter screens only for gas to pass through are fixed at the top and the bottom of the hierarchical porous tray respectively; the bottom of the tray is equipped witha stirring device. The composite pressing block is composed of an outer-circle metal hydride and an inner-circle phase change material. When a hydrogen storage material absorbs hydrogen, released heat is absorbed by the phase change material, and latent heat is stored; when the reactor releases hydrogen, the phase change material provides the heat to the hydrogen storage material to complete a dehydrogenation reaction. The reaction heat is recycled and used, an additional heat exchanger is not need, the structure is compact, the operation is simple, and the reactor is suitable for portable compact hydrogen power system application occasions, such as vehicle mounting, unmanned aerial vehicles, robots and the like.
