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.

The magnetic shield portion can be incorporated into at least one of the battery and the communication device. When the battery is inserted into mobile communication device, the magnetic shield portion is located substantially between a battery portion, in the battery, and the receiver.

Abstract: A system and method for delaying delivery of teleconference access information includes at least one processor, at least one computer readable medium in communication with the processor, and at least one program module stored on the medium. The module is operative to create a teleconference notification in response to a request from a requestor device. The module can also assign a date, time, and access information for the teleconference, receive an input from the requestor device to delay delivery of the access information, and deliver the teleconference notification to at least one participant device. The teleconference notification has at least the date and time of the teleconference but not the access information. The module delays delivery of the access information to the at least one participant. For example, delivery of the access information is delayed until a predetermined time period from the assigned date and time of the teleconference.

Abstract: The present disclosure relates to systems and methods for secure communications. In some aspects, one or more values used to generate an encryption key used to encrypt a packet are stored in a header of the packet. The packet is transmitted with the encrypted data portion in a communication. In some aspects, one or more values used to generate an encryption key are received. The encryption key is regenerated using the one or more values.

Search results are provided in threads at the display. Search results are automatically updated in response to receiving additional message data when the additional message data meets the search criteria.

Abstract: An electronic device includes an object sensor for detecting motion of an object, such as a stylus or finger, relative to device and during a period of contactless object movement. A motion sensor, such as an accelerometer, detects device motion during the period of contactless object movement. A processor determines a gesture that corresponds to the movement of the object and to movement of the device. This device, and the associated method, results in a more accurate determination of an intended gesture, such as a three-dimensional gesture. For example, the processor, or gesture determinator, can compensate for movement of the device when determining the gesture corresponding to detected contactless movement of the object.
