One or more techniques and / or systems are provided for synchronizing application state between one or more instances of an application on one or more devices. In particular, an application state, such as application settings, may be synchronized between a first instance of an application on a first device and a second instance of the application on a second device. For example, a user may configure a new email account within a first instance of an email application on a laptop device. The new email account may be synchronized with a second instance of the email application on a tablet device. During synchronization, various conflict resolution, version verifications, and / or consistency verifications may be performed. In this way, the user may be provided with a seamless and consistent experience between the laptop and tablet device.

A user interface, or a component of a user interface, is deployed as a service in a services oriented architecture for use, for example, in a data integration platform.

The present invention provides a system and apparatus for efficient and reliable, control and distribution of data files in large-scale distributed networks. The members of a group of servers in a multicast network elect a group leader whenever a new group leader is required, as when the prior group leader become unavailable, as detected by absence of a periodic heartbeat message published by the leader. The election is carried out by a system of voting by each candidate whereby each candidate has a priority calculated from its configuration, and the server with the highest priority is configured to claim the leadership faster than the other candidates. As part of the claim, each candidate multicasts its priority. Each candidate that receives a multicast claim for leadership from another candidate compares its own priority against the claimant and only votes for itself if its own priority is higher. After a preconfigured period of hearing no other claimants with higher priority, the candidate with the highest priority becomes the new leader.

A method, apparatus and computer program product are provided to synchronize multiple devices. In regards to a method, an indication is received that a view of a task is presented by a first device. The method causes state information to be provided to a second device to permit the second device to be synchronized with the first device and to present a view of the task, either the same view or a different view than that presented by the first device. The method also receives information relating to a change in state of the task that is provided by one of the devices while a first view of the task is presented thereupon. Further, the method causes updated state information to be provided to another one of the devices to cause the other device to remain synchronized and to update a second view of the task that is presented.

An email client and file manager provides combined file management and communications management in a single interface. An interface allows documents, email messages, contact information, web links or pages, and user-attached notes to be stored in the same folders. This facilitates communication by email and fax. The interface permits the user to combine this data in folders which the user categorizes according to a folder tree created by the user. In one embodiment of the invention, the client, in its email function, communicates with a dedicated host which in turn communicates with external servers according to standard internet protocol.

A transformation function of an extract-transform-load data integration process is deployed as a service in a services oriented architecture.

A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”

Real time data integration jobs are deployed in a services oriented architecture as services that allow multiple service bindings. In one aspect, a method includes providing a code module executing a data integration job and a registry of services for storing the code module. When the code module is identified in the registry, access is provided to the code module in the registry of services, in real time wherein the code module may be accessed by more than one type of service binding such that different applications can utilize the real-time integration service using different protocols to invoke the real-time integration service. At least one of the types of service bindings may be an EJB binding, a SOAP binding, a JMS binding, and a web service binding. The data integration job may include an extraction job, a data transformation job, a loading job, a metadata management job, and a data quality job.

The present invention relates to a wireless home automation system having controllers for controlling a broad variety of functions via two-way communication with a plurality of devices. More specifically, the invention relates to sharing information related to the system between controllers, e.g. by updating a second controller with the newly learned information of a first controller, or by replicating a controller by making a second controller a complete copy of a first controller. The information can be shared by generating and transmitting, with a first controller, a list of device identifiers of devices controlled by the first controller to a second controller. The list is received by the second controller and stored in a memory of the second controller dedicated to store device identifiers of devices controlled by the second controller. This function proves advantageous when new controllers are introduced or if a controller is lost, worn out, or destroyed.

A data storage medium comprises a plurality of data regions, and a plurality of servo regions configured to provide positioning information to a reading device. Each of the plurality of data regions corresponds to more than one of the plurality of servo regions. The more than one of the plurality of servo regions are configured to provide positioning information to the reading device at discrete times corresponding to a data operation of a corresponding data region.

A method of arranging synchronization of databases, the method comprising the steps of establishing a transport layer connection for synchronization between a first and a second device which synchronize databases. During initialization of synchronization a first update identifier, which is stored at least in the first device and describes the latest synchronization event the devices have performed in the databases, and a second update identifier, which is defined by the first device and describes the present synchronization, are transmitted from the first device to the second device. The second update identifier is stored in the first and the second device. The contents of the first update identifiers stored in the devices are updated in the first and the second device if synchronization has been performed and after this said transport layer connection has been ended substantially properly.

A method and system directed to negotiating and triggering media stream synchronization at the link layer in a QoS-enabled 802.11 WLAN, or other wireless, network. In one implementation, the present invention allows for improved performance of streaming network applications, such as video conferencing, over wireless links. In one implementation, the present invention also provides an optional mechanism whereby a mobile station can signal a need for on-the-fly throttling, if an application on the mobile detects that there is a need for better synchronization of two streams, such as a lower priority stream to a higher priority stream.

The invention is a system designed for acquisition of seismic data by means of acquisition stations set on water bottom of a water body. The system comprises acquisition stations (DSAU) combining a streamlined boom suited to penetrate the bottom and thus couple seismic receivers with the underlying formation, a sealed body for electronic data acquisition and communication modules. These acquisition stations (DSAU) are placed in the water and drop to the bottom under the effect of gravity. Relay buoys (RCB) are positioned at the surface, each with a GPS positioning module, a radio link with a central station (CCRU), on a ship for example, and modules providing acoustic communication with bottom acquisition stations (DSAU), which are used to determine the position of the stations in relation to the relay buoys and to exchange control data and seismic data (good running order data or possibly seismic traces acquired if the conditions lend themselves thereto) to provide seismic prospecting or monitoring of an underground formation.
