A method and system for monitoring moving parts relies upon a formatted surface of a moving part. The formatted surface includes an address pattern wherein a precise position relative to the address pattern can be determined from a portion of the address pattern. An electronic reading sensor detects a portion of the address pattern, and a processor uses the detected portion of the address pattern to determine a current position of the moving part.

A method and a cloud management node (200) for enabling usage of a virtual machine in a distributed cloud of resources for processing and storing of data. When receiving (2: 1 ) a VM image from a client (202) with a set of files of an operating system for running the virtual machine, the cloud management node distributes (2:2a-d) the VM image (204b) to a plurality of local data centers (204) forming the distributed cloud. In return, the cloud management node receives local identifications of the VM image from the local data centers, and creates (2:3) a mapping (200a) between the received local identifications and a global identification of the VM image. The global identification is then returned (2:4) to the client, thereby enabling the client to change the VM image in the local data centers by referring to the global identification in communication with the cloud management node.

Methods and nodes (200, 202) in a data distribution network, for distributing content to multiple consuming nodes (C1, C2, C3, . . . ). A first node (200) detects (2:2) multiple data flows (2:1b) of a first content from the first node to a second node (202) in the distribution network, when the first node operates as delivering node of the first content for the consuming nodes. The first node then instructs (2:4) the second node to operate as delivering node of the first content for the consuming nodes and redirects (2:5) the consuming nodes to use the second node as delivering node of the first content. The first node further reduces (2:6) the multiple data flows to a common data flow of the first content to the second node. Thereby, efficiency can be improved in the data distribution network by reducing the number of data flows between the first and second nodes.

Node, computer software and method for selecting a resource [20] that is available at multiple caches [14] connected in a communication network [80]. The method includes receiving from a user [18] a request for the resource [20]; identifying one or more caches [14a, 14b, 14c] of the multiple caches [14] that store the resource [20]; determining a total cost associated with a path between the user [18] and each cache [14a, 14b, 14c] of the one or more caches [14] storing the resource [20], the total cost including a static cost [Cf] that reflects a topology of the communication network [80] and a dynamic cost [Δ] which is indicative of changing conditions of the communication network [80]; and selecting one cache [14a] from the one or more caches [14a, 14b, 14c] that store the resource [20] based on a lowest total cost of the one cache [14a].
摘要:
The present invention provides a method and a caching node entity for ensuring at least a predetermined number of a content object to be kept stored in a network, comprising a plurality of cache nodes for storing copies of content objects. The present invention makes use of ranking states values, deletable or non-deletable, which when assigned to copies of content objects are indicating whether a copy is either deletable or non-deletable. At least one copy of each content object is assigned the value non-deletable. The value for a copy of a content object changing from deletable to non-deletable in one cache node of the network, said copy being a candidate for the value non-deletable, if a certain condition is fulfilled.

摘要:
A method and system for retrieving position-related information uses a map of a selected geographical area printed on a surface that includes an address pattern. Each position on the address pattern corresponds to a particular location within the selected geographical area. By detecting a portion of the address pattern with an electronic reading device, a precise position of the electronic reading device with respect to the address pattern can be determined. A server identifies the specific geographical location that corresponds to the precise position. The specific geographical location can then be stored or information relating to the specific geographical location can be retrieved and forwarded to the user of the electronic reading device. Preferably, the map is printed on a region of address pattern that is predefined as corresponding to the selected geographical area.
摘要:
A method and system for electronic data entry using an electronic reading device that detects at least one position of the electronic reading device relative to a predefined address pattern of a specially formatted surface. Data relating to the at least one detected position is transmitted, preferably via a wireless interface using a radio transceiver. The data is received by a separate electronic device that performs an operation using the received data, wherein the operation corresponds to an area on the address pattern that contains the at least one detected position. The operation, for example, can include initiating a hyperlink function.
