  • Patent number: 8307277
    Abstract: Event handlers associated with markup language documents represented in a web browser are identified efficiently in response to an event. The markup language document is represented as a hierarchical structure comprising nodes and edges. Nodes are associated with node types, each node type defining how descendants of the node respond to events. The markup language document provides mappings of sets of node types to sets of handlers. In response to an event associated with a node, the types of nodes encountered in a path connecting the node with the root node are identified. Handler sets of the node types encountered in the path connecting a node with the root node are used to determine the handlers to be executed in response to the event. Data is associated with nodes to allow handler code to distinguish between nodes of the same node type.

  • Patent number: 8307435
    Abstract: The execution of a software application is diverted to detect software object corruption in the software application. Software objects used by the software application are identified and their pointers are inspected. One or more tests are applied to pointers pointing to the virtual method tables of the software objects, addresses (or pointers) in the virtual method tables, and memory attributes or content of the memory buffer identified by the addresses for inconsistencies that indicate corruption. A determination of whether the software objects are corrupted is made based on the outcome of the tests. If software object corruption is detected, proper corrective actions are applied to prevent malicious exploitation of the corruption.

  • Patent number: 8306256
    Abstract: Users of an online system are authenticated based on signatures of cameras that were used to capture images uploaded to the online system. Users of an online system upload photos taken from their cameras. The online system extracts characteristic information about the camera that captured the photos. This information includes a mapping of faulty pixels, metadata included with the photos, a naming convention, and the like. The online system stores an association between the user and the camera. This association is used for authentication of the user. For authentication, the user is asked to upload new photos taken from the camera that the user used previously. The information extracted from the newly uploaded photos is matched against stored information of cameras used previously by the user. The user is successfully authenticated if the camera used for the newly uploaded photos matches a previously stored camera.

  • Patent number: 8307086
    Abstract: Applications in social networks support interaction between members through various types of channels such as notifications, newsfeed, and so forth. For each channel, applications are ranked based on their user affinity measures. User affinity is based on measuring positive and negative interactions by users as both senders and recipients of messages generated by applications. Metrics are computed for the different types of messages and interactions provided by applications. For each channel, an application receives user affinity score based on specific weighted combination of the metrics. Applications use channel resources to send messages to increase their user base. Given the large number of applications that are available, the extent to which applications are allowed to use channels is controlled, limiting their resource consumption. User affinity scores of applications calculated for a channel are used to decide the allocation of channel resources for an application.

  • Patent number: 8301498
    Abstract: A video demographics analysis system selects a training set of videos to use to correlate viewer demographics and video content data. The video demographics analysis system extracts demographic data from viewer profiles related to videos in the training set and creates a set of demographic distributions, and also extracts video data from videos in the training set. The video demographics analysis system correlates the viewer demographics with the video data of videos viewed by that viewer. Using the prediction model produced by the machine learning process, a new video about which there is no a priori knowledge can be associated with a predicted demographic distribution specifying probabilities of the video appealing to different types of people within a given demographic category, such as people of different ages within an age demographic category.

  • Patent number: 8301452
    Abstract: A system and method for retrieving distributed content responsive to voice data are disclosed. Voice data is transmitted from a source client device to media server which applies a mixing table to route the voice data to one or more destinations described by the mixing table. The media server also analyzes the received voice data for one or more events. Responsive to detecting an event, the media server communicates with an application server, which modifies the mixing table so that subsequent data is also routed to a media generator which analyzes voice data received after detection of the event for a command. The media generator communicates with the application server to retrieve data from a user data source, such as a website, associated with a detected command. The media generator produces an audio representation of the retrieved data which is communicated to the source client device via the media server.

  • Patent number: 8294504
    Abstract: In certain arrangements and methods, a reset-able counter (100) produces multiple delay times as required by, for example, a finite state machine. The counter (100) counts a stored value by a configurable amount. That configurable amount is determined based upon the period of a clock cycle divided by a desired time unit. The value held by the counter does not represent a count of clock cycles, but rather a count of time units. In other aspects, a device generates fixed delays derived from a variable frequency input clock. The device includes a count circuit (100) and a comparator (114, 116). The number of time-units between consecutive clock edges of the input clock is stored, and the count circuit changes a current-count value by a corresponding amount, with the change being responsive to a clock edge of the input clock. The comparator (114, 116) compares the current-count value to a fixed value that represents a fixed delay time.
