Abstract: Enabling a recipient to control presentation of an audio identifier informing the recipient of an arrival of a digital communication from a sender in a communication session includes receiving a digital communication from a sender directed to a recipient. A sender-designated first audio identifier or sender-related information that identifies the sender to the recipient is accessed upon arrival of the digital communication. The first audio identifier or sender-related information is presented to the recipient contemporaneous with receipt of the digital communication. The recipient is able to specify, upon presentation of the first audio identifier or sender-related information, whether to enable subsequent presentation of the first audio identifier prior to or concurrent with receipt of a future digital communication from the sender.

Abstract: The people a user is presumed to know or be associated with may be determined using a number of techniques. For example, the people within a certain number of degrees of separation from the user may be considered as known to the user. This information about people that the user knows is used in relation to the user's communications.

Abstract: Controlling the volume of an audible alert associated with an instant messaging communications session includes rendering, on a first instant messaging user system, an instant messaging application user interface for an instant messaging communications session involving at least a first instant messaging user and a second instant messaging user, receiving notification of an event related to the instant messaging communications session, determining a characteristic of the event, accessing an audible alert to be rendered to signal existence of the event, adjusting based upon the determined characteristic of the event a volume of the audible alert corresponding to the event, and rendering the audible alert to signal existence of the event.

Abstract: Audibly identifying an event includes enabling selection of a first sound based upon an identifier. The identifier enables identification of an entity related to the event. A notification of an occurrence of the event is received. The notification includes the identifier. An intended recipient is alerted of the event by playing, in response to the notification, at least a portion of the first sound and at least a portion of a second sound that is related to the event.

Abstract: Audibly informing a recipient of an arrival of a digital communication from a sender includes receiving a digital communication from a sender directed to a recipient and determining whether the digital communication is associated with an audio identifier that identifies the sender of the digital communication and that is designated by the sender of the digital communication. Perception by the recipient of the audio identifier is conditioned on whether the digital communication is determined to be associated with the audio identifier. The audio identifier is perceived prior to or concurrent with perception of the digital communication by the recipient.

Abstract: An electronic message may be reconfigured to effect an enhanced notification using an input interface to receive at least one electronic message created by or on behalf of a message source for delivery to an intended recipient. A matching engine determines whether the electronic message corresponds to a predetermined definition of an enhanced notification. An enhancement engine reconfigures the electronic message to the enhanced notification if stored information related to the intended recipient indicates that the intended recipient is subscribed to receive the enhanced notification. Reconfiguring the electronic message may include reconfiguring the message to provide special handling, routing or presentation.

Abstract: Automatically saving communicated multimedia objects to a repository for subsequent use includes in response to a sent electronic message and a received electronic message, identifying an embedded multimedia object or an attached multimedia object. The embedded multimedia object or the attached multimedia object is separated from the electronic message. The separated multimedia object is automatically saved to a repository for subsequent use by a user and the user is able to select the multimedia object from the repository for subsequent use.

Abstract: Informing a user of a large scale network dynamically of other network users includes determining dynamically an online context of the user. Other users presently within the online context of the user are identified and trait information is stored that is related essentially only to the user or to the other users in a users store associated with the online context. The user is informed dynamically of the other users based on the stored trait information, such as, for example, an age or other demographic identifier, or information indicative of an expertise, interest, preference, user type and/or other quality of the user or of the other individual.

Abstract: A real time notification system that tracks, for each user, the logon status of selected co-users of an on-line or network system and displays that information in real time to the tracking user in a unique graphical interface. The invention provides user definable on-line co-user lists, or “buddy lists”, that track specific co-users in real-time automatically. A user can create many separate buddy lists of co-users, either with intersecting or disjoint lists of users, and label these buddy lists according to the user's preference. The user can update a buddy list or create new buddy lists whenever necessary. When a user logs on to a system, the user's set of buddy lists is presented to the buddy list system. The buddy list system attempts to match co-users currently logged into the system with the entries on the user's buddy list. Any matches are displayed to the user. As co-users logon and logoff, a user's buddy list is updated to reflect these changes.

Abstract: A messaging application user interface has an input element for receiving electronic messages and an output element for displaying electronic messages. The messaging application user interface can be implemented so as to maintain a subset of the plurality of potential message recipients, the subset being determined using a predetermined criterion. The messaging application user interface also can be implemented so as to auto-complete a partially entered address based on the subset of potential message recipients. A set of user-selectable signals that modify auto-completion behavior also can be used with the messaging application user interface. The messaging application user interface can be used in an instant messaging system to allow a user to send instant messages to and exchange comments with a plurality of other users without having to switch among several instant message windows.

Abstract: The performance of a network system having one or more requester nodes, one or more provider nodes, and one or more intermediate nodes is improved by determining the digital signature of a received file, looking up the digital signature in an index of signatures, and forwarding a previously compressed version of the requested file when the digital signature is found in the index of signatures.

Abstract: A recompression server that automatically decompresses selected pre-compressed data streams and recompresses the decompressed data to a greater degree than the original pre-compressed data. In one embodiment, the recompression server determines from a request whether a requested file is pre-compressed. In another embodiment, the recompression server determines from a retrieved requested file's name or attributes whether the file is pre-compressed. Optionally, the recompression server may compress requested but previously uncompressed files. As another option, the recompression server may cache frequently requested files in re-compressed form to further optimize the bandwidth of a wide area network. Such caching can be done on-line or off-line.
