    Abstract: A first substrate mounted to a bonder head and a second substrate mounted to a base plate are held at different elevated temperatures at the time of bonding that provide a substantially matched thermal expansion between the second substrate and the first substrate relative to room temperature. Further, the temperature of the solder material portions and the second substrate is raised at least up to the melting temperature after contact. The distance between the first substrate and the second substrate can be modulated to enhance the integrity of solder joints. Once the distance is at an optimum, the bonder head is detached, and the bonded structure is allowed to cool to form a bonded flip chip structure. Alternately, the bonder head can control the cooling rate of solder joints by being attached to the chip during cooling step.

    Abstract: A method and system directed to negotiating and triggering media stream synchronization at the link layer in a QoS-enabled 802.11 WLAN, or other wireless, network. In one implementation, the present invention allows for improved performance of streaming network applications, such as video conferencing, over wireless links. In one implementation, the present invention also provides an optional mechanism whereby a mobile station can signal a need for on-the-fly throttling, if an application on the mobile detects that there is a need for better synchronization of two streams, such as a lower priority stream to a higher priority stream.

    Abstract: A method is provided for configuring a video conference endpoint. The method comprises receiving session data that comprises endpoint connection data for remote endpoints associated with scheduled conferences, and receiving a signal from a user interface indicating a user has activated a control associated with a selected conference, identifying the endpoint connection data for the remote endpoint associated with the selected conference, and establishing a media session with the associated remote endpoint. A video conference endpoint system also is provided. The system comprises a controller coupled to a memory, and a user interface coupled to the controller. The user interface includes a command button associated with a conference. The controller periodically receives session data associated with the scheduled conferences, stores the session data in the memory, and establishes the selected conference in response to a user activating the command button.
