  • Publication number: 20110078097
    Abstract: Face data sharing techniques are described. In an implementation, face data for a training image that includes a tag is discovered in memory on a computing system. The face data is for a training image that includes a tag associated with a face. The face data is replicated in a location in memory, on another computing system, so the face data is discoverable.

  • Patent number: 7418495
    Abstract: A system for monitoring user activity in an instant messaging session on a computer network periodically sends an activity message to other participants in the instant messaging session if the user has actively entered data during a first predetermined time interval. The system periodically sends a new activity message at intervals corresponding to the first predetermined time interval so long as the user is actively entering data during each time interval. If the user has not entered data during the first predetermined time interval, the system will not send an activity message. Other participants in the instant messaging session receive the activity message and generate an activity indicator on their respective displays. The computer receiving the activity message displays an activity indicator on the computer display in response to receipt of an activity message and starts a timer to measure a second predetermined time interval.
