Abstract: A method may include obtaining seismic data regarding a geological region of interest. The seismic data may correspond to a seismic survey that is divided into various bins in a predetermined bin grid. The method may further include determining a first multiblock bin within the seismic survey. The first multiblock bin may correspond to a source bin and a receiver bin among the bins. The method may further include determining traveltime table data using the seismic data and various multiblock bins that include the first multiblock bin. The method further includes determining migrated data using the seismic data, the traveltime table data, a velocity model, a migration function, and various parallel processors. The method further includes generating a seismic image of the geological region of interest using the migrated data.

Abstract: The present invention discloses a communication system and a method. The communication system includes at least first 802.11 equipment and second 802.11 equipment. The first 802.11 equipment including a network connector for searching relevant information of the second 802.11 equipment and modifying a network setting of the first 802.11 equipment according to the searched relevant information, and a 802.11 driver interface. The second 802.11 equipment includes a 802.11 driver interface. The driver interface of the first 802.11 equipment communicates with the driver interface of the second 802.11 equipment in accordance with the modified network setting.

Abstract: In a method for implementing device grouping and interactions between grouped devices a device creating a device group sends an advertisement message carrying identification information of a device group to which it belongs, to the network. After receiving the advertisement message, a network device joins the device group by the corresponding advertisement message. When two grouped network devices interact with each other, the method further comprises: sending an access request to an accessed device; judging by the accessed device whether the device sending the request is a trusted device and if so, interacting by both parties with each other; otherwise, denying the access request, or determining by the initiating device and the accessed device, a common trusted third party; acquiring by the initiating device, key information of the accessed device from the common trusted third party, and interacting with the accessed device by using the acquired key information.

Abstract: The invention discloses a method of discovering devices located in different wireless networks, a wireless network being built up for a device, wherein network is identified with a wireless network identification (Service Set Identification (SSID)) having an array for identifying device types, a correspondence between the array for identifying the device types and the device types being arranged at a user terminal, the method comprising steps of: A. searching for a currently available wireless network by the user terminal in a wireless network environment in order to obtain an SSID corresponding to the currently available wireless network; B. determining a device type corresponding to an array owned by the obtained SSID according to the arranged correspondence, and displaying a device icon for the device type corresponding to the SSID, by the user terminal. The method enables the user terminal to discover a device located in a wireless network different from the user terminal rapidly and conveniently.

Abstract: The present invention discloses a method for data transmission between devices in a network.

Abstract: The present invention discloses a method for implementing device grouping and interactions between grouped devices. In a network, a device creating a device group sends an advertisement message carrying identification information of a device group to which it belongs, to the network. After receiving the advertisement message, a network device which wants to join in the corresponding device group joins in the device group identified by the corresponding advertisement message.

Abstract: This invention discloses a method of calling service among devices in home network, comprising following steps: a service calling party obtains a service handle of the called service by using the characterized information of the service, sends a service calling request information to a called party by using the obtained called service handle; the protocol stack of the called party determines whether or not the called service exists based on the service handle of the called service contained in the request information and whether or not the called service has established a renting relationship with the service calling party after receiving the request information, if not, the flow will be ended; if it is, the called party sends service call response message containing service call result to the service calling party; after receiving the service call response message, the protocol stack of the service calling patty determines whether or not the service exist based on the service handle of the called service inc

Abstract: The invention relates to a method allowing dynamically networking among a plurality of devices to share resource. It includes: installing a software of dynamic networking and resource sharing on each of devices to realize dynamic networking and resource sharing. These devices periodically announce information with multicasting. A device serves as node control device, and announces the message of the existence of the device through multicasting, creates a node. A device can find the node by monitoring announcement message from the node. The device which requests to join into the node device registers its service information that can be provided by the device to the node control device. The device which has joined into the node finds the device providing service by indexing the nodal control device, and obtains desired service from the device by sending a service calling information. The method is applied to home backbone network for performing networking in home network.

Abstract: The invention discloses a method of searching for devices automatically in a network.
