Abstract: A lock secured around an IV hub includes a hollow barrel having an open upper end with a pair of hinged gates therein that are pivotal between an open and a closed position. Below the gates are a pair of spring-biased flaps that prevent the gates from opening. When a key coupled with a syringe is inserted into slots formed on the gates and rotated, the flaps are forced outwardly, allowing the gates to open with a downward force so that the syringe can be coupled with the IV hub. When the key is rotated in an opposite direction, the flaps automatically pivot toward the center of the barrel and lift the gates to the original closed position.

Abstract: Techniques for allocating/reducing storage required for one or more virtual machines are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for allocating storage for one or more virtual machines. The method may comprise providing one or more virtual machines. The method may also comprise creating one or more master images containing one or more commonly used blocks. The method may also comprise creating one or more Copy on Write volumes, where each Copy on Write volume may be associated with at least one of the one or more virtual machines and at least one of the one or more master images, and wherein updated blocks may be stored in at least one of the one or more Copy on Write volumes, thereby reducing storage required for one or more virtual machines.

Abstract: Techniques for implementing an adaptive data access error handling policy are disclosed. In one particular exemplary embodiment, the technique may be realized as a system comprising a shared storage device communicatively coupled to a network, and a computer cluster communicatively coupled to the network, the computer cluster comprising a plurality of nodes each mounting a shared file system thereon, a first node of the plurality of nodes to send a data access request to the shared storage device, to identify a data access error associated with the data access request, and to determine whether to permit access to the shared file system based on the data access error being a local data access error or a global data access error.
