Abstract:

A system and method is described herein for managing bandwidth and cost in connection with a plurality of sensors in an ad hoc network. The system and method receives sensor data that is provided from a plurality of sensors and constructs an ad hoc network among the plurality of sensors based on the sensor data. The system and method also receives and analyzes bandwidth information from each sensor in a group of sensors in the ad hoc network. Based on the analysis, the system and method then modifies a manner in which at least one sensor in the group exchanges data, including sensor data and multimedia content.

Abstract:

Methods and systems for generating information about a physical context of a user are provided. These methods and systems provide the capability to render a context avatar associated with the user as a composite image that can be broadcast in virtual environments to provide information about the physical context of the user. The composite image can be automatically updated without user intervention to include, among other things, a virtual person image of the user and a background image defined by encoded image data associated with the current geographic location of the user.

Abstract:

A system and method for deriving income from URL based context queries. A URL based user context query is received over a network from a user, wherein the user context comprises at least one user context criteria. A query is formulated based on the context criteria so as to search for user profile data, social network data, spatial data, temporal data, topical data and context query bid data that is available via the network and relates to the context so as to identify entries in a context query bid database that relate to user context criteria. A dynamic webpage is generated having content relating to the query and advertisements associated with the selected bid are inserted into the webpage. The dynamic webpage is transmitted to the user. The advertiser associated with the selected bid is charged a fee when a user interface event relating to the dynamic webpage occurs.

US Classification:

455466, 4554121, 4554141, 709206

Abstract:

Communicating data by transforming images or other non-text data into subsets of text characters and communicating each subset in an electronic message that can carry only a limited number of text characters. An embodiment transforms portions of binary data of an image or other non-text data into subsets of hexadecimal data that represents text characters. The subsets of hexadecimal text character data are included in SMS messages that have a predefined maximum number of characters. A header is included in the SMS messages to identify the ordering of the data. The SMS messages are communicated to a receiving device that orders the messages, transforms each subset of hexadecimal text characters back into the binary data, and assembles the binary data into it prior form for rendering to a user of the receiving device. A server may process the SMS messages, such as by inserting additional SMS messages with advertising data.

US Classification:

4554561, 455418, 4554566, 709217

Abstract:

Disclosed are apparatus and methods for providing location information for a current location of a portable device, such as a camera-phone. In general, a current, generic location, e. g. , cell ID, of the portable device is mapped to a more specific location description, e. g. , the name of a specific city, that is defined by one or more users. In a specific implementation, one or more users of portable devices may be encouraged to contribute specific location descriptions with respect to media objects or the like that are managed on their portable devices. When a particular user ties a specific location to a media object or the like, the media object serves to also tie the particular user's current generic location or cell ID to the media object. Thus, a plurality of media objects and their associated specific and generic location descriptions can be analyzed to determine a most relevant specific location description for a particular generic location or cell ID. The specific location that is tied to a generic location may be used in any number of applications, such as automatically associating such specific location with any media objects that are captured in the corresponding generic location, e. g. , cell ID.

US Classification:

707709, 707722, 707784

Abstract:

A system and method for generation of URL context queries. A request is received over a network from a user for generation a URL based context query, wherein the request comprises at least one query generation criteria. A multidimensional dataspace having a spatial axis, a temporal axis, a topical axis and a social axis is searched for clusters of related data objects using the query generation criteria, wherein at least one cluster of data objects relating to the query generation criteria is identified. Permissions are checked relating to each data object cluster of related data objects. If the user does not have permission to view the data object, it is removed from the cluster. A URL having a context query comprising at least one context criteria is generated from the properties of the cluster of data objects. The URL having a context query is then transmitted to the end user.

Abstract:

Disclosed are apparatus and methods for performing actions with respect to objects. An object having an action tag, that specifies that a particular action script is to be performed with respect to the object, is provided. The action tag can be in the form of a textual label or any suitable user interface object that can be associated with the object. A search is then performed in a plurality of reference action tags, that each correspond to a different action script, for the provided action tag. When a matching reference action tag is found for the provided action tag, the corresponding, matching action script is then invoked so that the matching action script is automatically performed with respect to the object. Embodiments of the present invention also provide an action tag management architecture that is independent of the actions that are triggered by the action tags associated with particular objects and, accordingly, provides flexibility by allowing the set of actions to be expanded without requiring code changes to the tag management architecture.

International Classification:

G06F 17/30

US Classification:

707732

Abstract:

Search results may include both objective results and person results. In one example, a search query is evaluated to determine whether it is the type of query that a user might want to ask to a friend. If the query is of such a type, then the search engine may examine a social graph to determine which friends of the user who entered the query may have information that is relevant to answering the query. If such friends exist, then the friends may be displayed along with objective search results, along with an explanation of each friend's relevance to the query. Clicking on a person in the results may cause a conversation to be initiated with that person, thereby allowing the user who entered the query to ask his or her friend about the subject of the query.
