摘要： A method and system are provided for reconfiguring a multiple node system after an epoch change in a manner that reduces the overhead and system unavailability typically incurred during reconfiguration. A resource-to-master mapping is established using the combination of a resource-to-bucket hash function and a bucket-to-node hash function. The resource-to-bucket hash function is not changed in response to an epoch change. The bucket-to-node hash function does change in response to epoch changes. Techniques are disclosed for adjusting the dynamic bucket-to-node hash function after an epoch change in a manner that load balances among the new number of nodes in the system. Further, the changes to the bucket-to-node assignments are performed in a way that reduces the number of resources that have to be remastered. In one embodiment, only those resources that lose their masters during an epoch change are assigned new masters during an initial reconfiguration. Load balancing is then gradually achieved by migrating resources after the system has been made available. The old masters of resources forward access requests to new masters of resources once they have transferred the master resource objects for the requested resources. In addition, techniques are disclosed for migrating resources from a node in anticipation of a planned shutdown of the node.

摘要： Provided herein is a name service that includes published data that is associated with one or more duration entities and one or more modification entities, enabling the name service to more efficiently manage access to published data. To publish data, a publishing client transmits a publication request to a name service. The publication request may specify a modification entity. The name service creates at least one name entry that associates the published data with the modification entity. There are several types of requests to modify data that a name service will honor only when they originate from a modification entity.

摘要： A composition and method of detecting counterfeit paper currency includes applying a test solution to a paper currency having ink printed thereon. If the paper currency is counterfeit, the test solution causes the ink to release from the paper currency. If the paper currency is genuine, the ink will not release from the paper currency. The test solution may be an aqueous-alcohol solution having a chemical thickener, and preferably includes a de-foaming agent, a bactericide/fungicide and a fragrance.

摘要： A CAM bank is functionally divided into two or more sub-banks, without replication CAM driver circuits, by disabling all match line discharge circuits in the bank, and selectively enabling the discharge circuits in comprising sub-banks. At least one selectively actuated switching circuit is interposed between the virtual ground node of each discharging comparator in the discharge circuit of a sub-bank and circuit ground. When the switching circuit is in a non-conductive state, the virtual ground node is maintained at a voltage level sufficiently above circuit ground to preclude discharging a connected match line within the CAM access time. When the switching circuit is placed in a conductive state, the virtual ground node is pulled to circuit ground and the connected match line may be discharged by a miscompare. Control signals, which may be decode from address bits, are distributed to the switching circuits to defined the CAM sub-banks.
摘要翻译：通过禁用组中的所有匹配线放电电路，并且选择性地使能包括子组的放电电路，CAM组在功能上被划分为两个或更多个子组，而不需要复制CAM驱动器电路。至少一个选择性致动的切换电路插入在子组的放电电路中的每个放电比较器的虚拟接地节点和电路接地之间。当开关电路处于非导通状态时，虚拟接地节点保持在足够高于电路接地的电压电平，以防止在CAM访问时间内放电连接的匹配线。当开关电路处于导通状态时，虚拟接地节点被拉到电路接地，并且连接的匹配线可能被误比较地放电。可以从地址位解码的控制信号被分配到切换电路以定义CAM子库。

摘要： A method and system for exposing a version-independent interface to a computer resource. The interface system exposes a version-independent interface to a computer resource, such as a database or computer program. The interface system also provides a version-dependent interface to the computer resource that is typically not exposed. When the computer resource is modified, the version-dependent interface may be modified, but the version-independent interface might not be modified. When the version-dependent interface is modified, a mapping is generated (in some cases automatically) between the version-independent interface and the version-dependent interface. When an accessing computer program uses the version-independent interface to request services of the computer resource, the system uses the mapping to map the request to a request that is appropriate for the version-dependent interface.

摘要： A system and method for monitoring and characterizing various sources of RF interference within an RFID environment, and for adjusting the operational characteristics of an array of RFID readers within the system based on these interference characterizations. The system examines the received transmissions from readers in the network by controlling a calibration cycle or while they are operating as interrogators to determine interference parameters, and to verify the operation of the readers in the array. The system also examines outside sources of interference, and signal dependent interference. The interference characterization can also be estimated from a combination of calculations and co-monitoring.
