摘要： An electrical adapter having a manually retractable cable assembly where the electrical contacts of the retractable cable assembly are disposed along an axis of rotation to minimize the friction between the cable and contacts therein when the cable is extended and retracted. The electrical adapter includes a housing; an electrical plug assembly including an interchangeable module coupled to an adapter module, the interchangeable module having a plurality of prongs for receiving a first voltage when mated with an electrical receptacle, and a converter electrically coupled to the assembly for converting the first voltage into a second voltage; and a retractable cable assembly supported by the housing and electrically coupled to the converter. The retractable cable assembly includes a cable coupled at one end to an electrical plug for outputting the second voltage, a reel for winding and unwinding said cable, the reel being rotatably supported by the housing, a wheel mounted to the reel for enabling the cable to be manually dispensed from and retracted into the housing.

摘要： An electrical adapter is supported by a housing and includes an electrical plug assembly having an input for receiving a high voltage, a converter electrically coupled to the assembly for converting the high voltage to a low voltage, and a retractable cable assembly supported by the housing and electrically coupled to the converter. The retractable cable assembly includes a cable coupled at one end to an electrical plug for outputting the low voltage to the electrical device, and is enabled to retract the cable. In a preferred embodiment, the retractable cable assembly includes slots defined within a bore of a cable reel to support a pair of first interengageable electrical contacts coupled to the other end of the low voltage cable. These electrical contacts rotationally mate with a pair of second interengageable electrical contacts disposed along the axis of rotation within the retractable cable assembly. One of the first contacts includes a pair of edges defining a gap therein. One of the second contacts defines a sleeve having a spiral inclined portion. When the contact having the gap rotates around the sleeve, the problem of intermittent electrical contact that arises with the gap rotating about the sleeve and coinciding with gaps within the sleeve is eliminated, and continuous electrical contact is established therebetween.

摘要： A KVS tree database and operations thereon are described herein. A KVS tree database is a multilevel tree that includes a base level and subsequent levels. The base level includes a heterogeneous kvset in a node, The heterogeneous kvset including entries for multiple KVS trees, such as a first entry for a first KVS tree and a second entry for a second KVS tree, The subsequent level includes a first node including a first homogeneous kvset for the first KVS tree and a second node including a second homogeneous kvset for the second KVS tree. Here, a homogeneous kvset includes nodes from only one KVS tree. The KVS tree database also includes a first determinative mapping of entries between the base level and the subsequent level and a second determinative mapping of entries between subsequent levels.

摘要： Systems and techniques for reducing probabilistic filter query latency are described herein. A query for a probabilistic filter that is stored on a first media may be received from a caller. In response to receiving the query, cached segments of the probabilistic filter stored on a second media may be obtained. Here, the probabilistic filter provides a set membership determination that is conclusive in a determination that an element is not in a set. The query may be executed on the cached segments resulting in a partial query result. Retrieval of remaining data of the probabilistic filter from the first media to the second media may be initiated without intervention from the caller. Here, the remaining data corresponds to the query and data that is not in the cached segment. The partial query results may then be returned to the caller.
