Abstract: Techniques for managing references to containers are disclosed. In one particular embodiment, the techniques may be realized as a method for managing references to containers comprising comparing at least one identifier to a first bloom filter, generating a first list of identifiers based on the comparison of the at least one identifier and the first bloom filter, comparing the first list of identifiers to a second bloom filter, generating a second list of identifiers based on the comparison of the first list and the second bloom filter, comparing the second list of identifiers to a main container list, and determining whether an image refers to a container based on the comparison of the second list and the main container list.

Abstract: An electrical assembly selectively receives power from an external power supply. The electrical assembly includes a base that at least partially defines a tool port and a battery port and an electrical tool selectively coupled to the tool port. A rechargeable battery pack is selectively coupled to the battery port and a circuit is supported by the base and is operable to direct power to the tool port and the battery port such that the external power provides power to the electrical tool to operate the electrical tool and to recharge the rechargeable battery pack.
