Abstract: The present disclosure discloses a quick detachable hard disk bracket. When the cross beam hinging rod and the enclosure frame driving rod rotate upwards or downwards, the enclosure frame is driven to transversely move opposite to the cross beam. The locking hook is slidably assembled at the cross beam in a transverse direction. The locking hook is hinged with a hook driving rod. When the cross beam hinging rod and the enclosure frame driving rod rotate upwards or downwards, the locking hook is driven to transversely move opposite to the cross beam. When the cross beam hinging rod and the enclosure frame driving rod rotate downwards, the locking hook and the enclosure frame move in opposite directions respectively, and the locking hook and the enclosure frame move out of the two ends of the cross beam respectively.

Abstract: The present application discloses a multi-node safe locking device. A guiding rail is disposed on a chassis, to enable a locking rod to translate perpendicularly to the moving direction of node modules. A guiding plate is assembled on the node modules, guiding grooves are disposed on the guiding plate, and the guiding grooves match with a plurality of limiting columns that protrude out of the locking rod. When the node modules moves, the limiting columns move relatively to the guiding grooves in a guiding path, to cause the locking rod to translate. When one of the node modules is pulled out, the guiding groove causes the locking rod to translate to the locking position, to block the other node module from being pulled out, the limiting column is separated from the notch of the guiding groove, and the guiding plate moves out along with the node module.

Abstract: The present disclosure discloses a node safe locking device and a server. An outer rail is disposed between two adjacent node modules. A middle rail is slidably assembled at the outer rail. Each middle rail is driven by one node module to translate in a same direction. When the middle rail moves, the linking and interlocking rod may be driven to reach different positions. When the middle rail moves outwards from the initial position together with one of the node modules, the locking guiding lean edge drives the linking and interlocking rod to move to the locking position. At this time, the blocking locking edge of the middle rail corresponding to the other node module is blocked by the linking and interlocking rod located at the locking position, and the node module may not move outwards to realize locking.

Abstract: Methods, systems, and computer storage media for providing observation stream data of security incidents using an observation stream engine in a security management system. An observation stream framework supports continuously generating and presenting observation stream data that facilitates developing a working hypothesis of an active security incident. The observation stream framework can also include observation stream query-types that can be selected for running queries against a plurality of security data sources. In operation, an observation stream query is accessed. The observation stream query is a user-generated observation stream query associated with an observation stream query-type. The observation stream query-type comprises parameters for querying a plurality of security data sources and dynamic tracking of a security incident. The observation stream query is executed and observation stream data is generated.

Abstract: The present invention relates to a palladium-based supported hydrogenation catalyst and a preparation method and application thereof. The catalyst is prepared by the following method: impregnating an Al2O3-containing carrier with an organic solution containing a bipyridine derivative having hydroxy group, optionally drying followed by impregnating with a mixed solution containing the main active component palladium ions and the auxiliary active component Mn+ ions, where M is one selected from Ag, Au, Ni, Pb and Cu; and then optionally drying, and calcining to obtain the catalyst. The preparation method provided by the present invention allows Pd atoms and M atoms to be highly uniformly dispersed on the carrier, which overcomes the adverse impact of the surface tension of the impregnation solution and the solvation effect on the dispersibility of active components.
