Abstract: Various embodiments provide protection against web resources associated with one or more undesirable activities. In at least some embodiments, a method detects and responds to a user-initiated activity on a computing device. Responding can include, by way of example and not limitation, checking locally, on the computing device, whether a web resource that is associated with the user-initiated activity has been identified as being associated with a safe site. If the web resource is not associated with a safe site, the user will be notified and given the option to check remotely, away from the computing device, whether the web resource is identified as being at least possibly associated with one or more undesirable activities.

Abstract: A method, program and apparatus for limiting processing resources incurred due to refreshing a user interface of a first terminal. The method comprises: at a first terminal, receiving a plurality of event indications which indicate respective events, each of the event indications being received at a different time; and based on the event indications, refreshing the user interface of the first terminal to reflect each of the respective events. Refreshing comprises determining a plurality of time periods, and during each of those time periods postponing the user interface from being refreshed to reflect any outstanding ones of the event indications until that time period has elapsed. The time periods are each determined having a length set in dependence on a timing of the receipt of one or more of the event indications, wherein the length of a later time period is set to an increased value relative to an earlier time period in response to the receipt of one or more of said event indications within a time limit.

Abstract: Embodiments of camera-based scanning are described. In various embodiments, scanned documents can be created using images captured by a camera associated with a device. An image captured by the camera is processed to identify portions within the image that correspond to rectangular objects such as paper, business cards, whiteboards, screens, and so forth. One or more of these portions can be selected for scanning automatically based on a scoring scheme and/or semi-automatically with the aid of input from a user. One or more scanned documents are created from the selected portions by un-warping the selected portions to remove effects of perspective (e.g., rectify the portions to rectangles) and applying various image enhancements to improve appearance.

Abstract: A node, such as a session node including any network node, located in a first network transmits data to one of a plurality of devices located in a second network. A determination is made that another device connected to the node is located in the second network. The node transmits to the other device located in the second network a message addressed to the one of said plurality of devices via the connection between the node and the other device effective to cause the message to be forwarded from the other device to the one of said plurality of devices via a connection established within the second network.

Abstract: A method is provided of authorizing a user of a communication system to be added to a group communication event. The method comprises: selecting a group of users of the communication system; initiating from a host node the group communication event with the group of users; responsive to receiving a group communication acceptance from at least a first user in the group, establishing the group communication event with the first user in the group; receiving at the host node a communication set up request from another user of the communication system; analyzing the communication set up request to determine if said communication set up request is associated with said group communication event initiated by the host node; and adding said other user to the group communication event if it is determined that the communication set up request is associated with said group communication event.

Abstract: Super-clusters of point-of-interest locations are created based on how close the point-of-interest locations are to one another. Additionally, one or more mini-clusters are created in each of the super-clusters based on how close the point-of-interest locations within each super-cluster are to one another. For each of one or more mini-clusters, some point-of-interest icons corresponding to the point-of-interest locations are placed based at least in part on a mean out positioning vector that is based at least in part on a center of the mini-cluster and a center of the super-cluster that includes the mini-cluster. Additionally, some point-of-interest icons are attempted to be placed as a group, while others are attempted to be placed individually.

Abstract: A Grid Proxy Architecture for Network Resources (GPAN) is proposed to allow Grid applications to access resources shared in communication network domains. GPAN bridges Grid services serving user applications and network services controlling network devices through its proxy functions such as resource data and management proxies. Working with Grid resource index and broker services, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources such as bandwidth for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. Resource-based XML messaging is employed for the GPAN proxy communication.

Abstract: Various embodiments provide a guard mechanism that is configured to prevent transmission of synchronous function calls to hung application components. In at least some embodiments, a hang resistance application layer intercepts a synchronous function call that is intended for an application component. Before permitting the synchronous function call to be transmitted to the application component, the hang resistance application layer determines whether the application component is hung by transmitting a message other than the synchronous function call to the application component that requests that a response be received before transmission of the synchronous function call to the application component is permitted. Responsive to determining that the component is hung, a hung component recovery process is initiated.

The data is divided into a plurality of portions that do not exceed the threshold amount. A plurality of messages is formed to communicate the divided data across domains.

Abstract: In embodiments of managing subscribers on a cellular network, a service provider tracks subscriber devices that are connected for voice communication via a network. The service provider can estimate an increased service load on the network by combining a number of the subscriber devices estimated to still be connected at an appointed time with a number of additional subscriber devices estimated to request connection at or within a predetermined range of the appointed time. The service provider can then cause a number of inactive subscriber devices to be disconnected for at least a predetermined period of time in anticipation of the increased service load.
