Abstract: Methods and systems for providing simplified presence for a user are described. The user has a plurality of associated communication devices registered with a communications server, and each communication device enables at least one communication service class. The server has a user data entry associating the user with each of the plurality of communication devices. To hide the details of the user-associated devices from third parties, a virtual device is defined and associated with the user. Presence information received at the server from the various devices is aggregated together to create aggregated presence information that indicates at least the service classes available from the user-associated devices based on the received presence information. A virtual device presence document is generated containing the aggregated presence information and is provided to a presence server as presence information associated with the user.

Abstract: A method and system of establishing calling preferences for a user are provided. The method includes: defining a user profile containing an association between the user and two or more communication devices, each device having an associated device type; assigning the user to at least one group; obtaining group preferences associated with one or more of the user's groups; determining user preferences for the user based on the group preferences and the device types of the communication devices associated with the user; and storing the user specific preferences in a user profile associated with the user.

Abstract: A method and system for call management is provided. In a system embodiment a call manager server is provided that can managing incoming call requests from certain telephony devices and effect connections to other telephony devices based on those incoming call requests. The call manager server can also maintain a policy that defines permissions as to whether certain telephony devices can request interruption of an ongoing phone call at a destination telephony device.

Abstract: An apparatus includes an image buffer, a graphics buffer, a memory, a router, and a sensor interface. The apparatus further includes a memory controller for controlling transfer of image data from the image buffer to the memory via the router and for controlling transfer of graphics data from the memory to the graphics buffer via the router. The apparatus also includes an image controller simultaneously operable with the memory controller for controlling transfer of the image data from the sensor interface to the image buffer. Optionally, the sensor interface comprises a receiver and a transmitter. Optionally, the apparatus further includes a header buffer, and a header controller simultaneously operable with the memory controller for controlling transfer of header data from the sensor interface to the header buffer. The apparatus optionally further includes a sensor for communicating with the header controller via the sensor interface.
