    摘要： In a system including a collection of cooperating cache servers, such as proxy cache servers, a request can be forwarded to a cooperating cache server if the requested object cannot be found locally. An overload condition is detected if for example, due to reference skew, some objects are in high demand by all the clients and the cache servers that contain those hot objects become overloaded due to forwarded requests. In response, the load is balanced by shifting some or all of the forwarded requests from an overloaded cache server to a less loaded one. Both centralized and distributed load balancing environments are described.

    摘要： A power supply device using electromagnetic power generation includes an electric motor, an electromagnet, a winding, a rechargeable unit, and a battery case. The electromagnet is operatively connected to the electric motor so that an activation of the electric motor changes a magnetic field of the electromagnet. The winding is around the electromagnet so that the change of the magnetic field of the electromagnet generates emf in the winding. The rechargeable unit is electrically connected to both the electric motor and the electromagnet so that the emf is stored in the rechargeable unit or supply to an external electric load. The battery case includes an electrical wire electrically connected to the winding.

    摘要： Range query techniques are disclosed for use in accordance with data stream processing systems. In one aspect of the invention, a technique is provided for indexing continual range queries for use in data stream processing. For example, a technique for use in processing a data stream comprises obtaining at least one range query to be associated with the data stream, and building a range query index based on the at least one range query using one or more virtual constructs such that the query index is adaptive to one or more changes in a distribution of range query sizes. The step/operation of building the range query index may further comprise building the range query index such that the range query index accommodates one or more changes in query positions outside a monitoring area of the at least one range query. In another aspect of the invention, a technique is provided for incrementally processing continual range queries against moving objects. For example, a technique for evaluating one and more continual range queries over one and more moving objects comprises maintaining a query index with one and more containment-encoded virtual constructs associated with the one and more continual range queries over the one and more moving objects, and incrementally evaluating the one or more continual range queries using the query index.
