    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 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 system and method are provided in which access point (AP) devices in a wireless local area network (WLAN) are typed or configured into one of three measurement and reporting roles: Monitor-Mode AP (MMAP), Portal AP (PAP), a Border AP (BAP) or an Interior AP (IAP). APs are assigned specific link measurement requirements according to their assigned type or role. In general, MMAPs and PAPs have the greatest measurement and reporting responsibilities, BAPs have less measurement and reporting responsibilities than PAPs and IAPs have the least measurement and reporting responsibilities. The APs generate measurements that are supplied to appropriate equipment to facilitate handover decisions with respect to a dual-mode wireless client device that roams between the WLAN and another network or vice versa. As a result, link measurements are only performed by APs in locations where such measurements are necessary for handover service, thus reducing the overall processing load on the WLAN infrastructure.

    Abstract translation: 提供了一种系统和方法,其中无线局域网(WLAN)中的接入点(AP)设备被输入或配置为三个测量和报告角色之一:监视模式AP(MMAP),门户AP(PAP) 边界AP(BAP)或内部AP(IAP)。 AP根据其分配的类型或角色为特定的链路测量要求分配。 一般来说,MMAPs和PAPs具有最大的测量和报告责任,BAP的测量和报告责任比PAP更少,IAP具有最少的测量和报告责任。 AP产生提供给适当设备的测量结果,以便于相对于在WLAN和另一网络之间漫游的双模无线客户端设备进行切换决策,反之亦然。 因此,链路测量仅由AP在这种测量对于切换服务是必需的位置中执行,从而减少WLAN基础设施上的整体处理负担。

    Abstract: A voice over WLAN diagnostic system. In particular implementations, a method includes simulating, in response to a triggering event, Voice over Internet Protocol (VoIP) communications with a remote diagnostics engine; gathering metric data characterizing one or more aspects of the simulated VoIP communications; and periodically transmitting diagnostic packets including the metric data to the remote diagnostics engine; wherein the simulating VoIP communications comprises transmitting diagnostic protocol packets that simulate VoIP communications to the remote diagnostic engine; and intercepting diagnostic protocol packets received from the diagnostics engine.
