Abstract: A presence aggregation system provides a presence aggregation server that allows for the publication of presence state of a publisher from the publisher's multiple endpoints. A presence state includes an availability value and an activity. An activity may include an activity token and/or a custom string. When any one of the publisher's endpoints makes a presence state publication on the presence aggregation server, the presence aggregation server generates an aggregated state of the publisher (i.e., the availability of the publisher aggregated across all of the publisher's endpoints) and publishes the generated aggregated state to each of the publisher's endpoints. The presence aggregation server may also provide the publisher's aggregated state to the subscribers of the publisher's aggregated state information.

Abstract: Methods and related apparatus pertaining to downhole and surface telemetry, such as a method in which a telemetry system is provided with a communication path formed with an electrically conductive transport medium coupled across a plurality of downhole nodes. Such method includes operating on the communication path with a multi-drop system that provides telemetry to the downhole nodes in a wellbore, including employing modulation in a master-slave arrangement using binary differential phase shift keying or differential quadrature phase shift keying.

Abstract: A method and system for presenting a user interface displaying a view of a user's presence aggregated across multiple endpoints is provided. The view provides a visual display of the user's aggregated availability by displaying an indication of the user and an icon that pictorially indicates the aggregated availability of the user. The aggregated availability is the availability of the user aggregated across the user's multiple endpoints. The view may also include a text string describing the user's current aggregated availability or activity. The user interface may also display a view of the user's contacts, which includes an icon that indicates each contact's current aggregated availability.

Abstract: A presence aggregation system provides a presence server that allows users to publish information regarding their availability with the presence server. The presence server maintains a record of each user's published information. When an endpoint publishes information regarding a user's availability at that endpoint with the presence server, the presence server provides all of the user's published information, including the information just published, to each of the user's endpoints, including the endpoint which published the information. This allows each of the user's endpoints to generate an aggregated availability of the user. The presence server may also provide all of the user's published information, including the information just published, to each of the subscribing users' endpoints. This allows the subscribing users to also generate a view of the user's aggregated availability.

Abstract: A call forwarding system forwards telephone calls based on presence information of a user as reported by computing devices associated with a telephone number. When a telephone system receives an incoming call directed to one of the telephone numbers of the user's computing devices, it sends an incoming call event to each computing device. Upon receiving the incoming call event from a telephone system, each computing device determines whether the user is most likely present at that computing device based on the presence information. When a computing device determines that the user is most likely present at that computing device, it sends a notification to the telephone system to forward the incoming call to the telephone number associated with that computing device to effect the automatic forwarding of a call based on presence information.

Abstract: A muting system that allows audio of a computing device to be automatically muted when a telephone call is received on a telephone number associated with the computing device is provided. When an incoming call event occurs for that telephone number, the computing device directs a software component to mute the audio. When the muting system subsequently receives a call event indicating that the call has terminated, it may automatically un-mute or resume the software components. The muting system may allow a user to manually specify to un-mute or resume the software components.

Abstract: A method and system for providing notifications of changes in the presence state of contacts is provided. A notification system allows a user to specify those contacts of interest for whom the user wants to be notified when the contact enters a certain presence state. When presence information is received about a contact, the notification system determines whether the contact is a contact of interest as specified by the user. If so, then the notification system determines whether the presence information indicates a change in presence state that is of interest to the user. If the contact and the change in presence state are of interest to the user, the notification system notifies the user.
