    • The present invention is a putting tool to assist a golfer. The putting tool comprises a box like structural housing having a cavity therein. The housing is further defined by a top wall, bottom wall, back wall, first side wall, and an opposing second side wall. The front of the housing defines an opened an entry way for inserting foam into the cavity of the housing. An elastic band covers the front opening of the housing. At a predetermined location on the elastic band, a target is incorporated onto the band. Thus, when the golf ball hits the elastic band, the ball bounces off the band and automatically returns back to the putter.
    • 本发明是一种用于协助高尔夫球手的投掷工具。 放置工具包括其中具有空腔的盒状结构外壳。 壳体还由顶壁,底壁,后壁,第一侧壁和相对的第二侧壁限定。 壳体的前部限定了用于将泡沫插入壳体的空腔中的打开的入口方式。 弹性带覆盖壳体的前开口。 在弹性带上的预定位置,将目标结合到带上。 因此,当高尔夫球击中弹性带时,球从弹跳带弹起并自动返回到推杆。

    • A fast roaming (handoff) service is provided for a WLAN infrastructure. A given mobile station (STA) obtains a pairwise master key (PMK) when it associates with an access point (AP) in the infrastructure. A neighbor graph identifies prospective APs to which the STA may then roam. At initialization, preferably the neighbor graph is fully-connected (i.e., each AP is assumed to be connected to every other AP). The PMK (obtained by the STA initially) is shared proactively with the neighbor APs as indicated in the neighbor graph. Thus, when the STA roams to a neighbor AP, because the PMK is already available, there is no requirement that the STA initiate a real-time request to an authentication server to re-associate to the new AP. Further, the new AP causes an update to the neighbor graph information implicitly by simply issuing a notification that it is now handling the STA that arrived from the prior AP; in this manner, the prior AP is confirmed as a neighbor, but there is no requirement for any inter-AP dialog before a given neighbor graph is updated. As roaming occurs the neighbor graph is pruned down (to reflect the actual neighbor AP connections) using the implicit notification data.
    • 为WLAN基础设施提供快速漫游(切换)服务。 当给定移动站(STA)与基础设施中的接入点(AP)相关联时,获得成对主密钥(PMK)。 邻居图识别STA可能漫游的预期AP。 在初始化时,优选邻居图是完全连接的(即,假设每个AP被连接到每个其他AP)。 PMK(由STA最初获得)与邻居图中所示的相邻AP主动共享。 因此,当STA漫游到邻居AP时,由于PMK已经可用,所以不要求STA向认证服务器发起与新AP重新关联的实时请求。 此外,新的AP通过简单地发出它正在处理从先前的AP到达的STA的通知来隐式地更新邻居图信息; 以这种方式,先前的AP被确认为邻居,但是在给定的邻居图更新之前不需要任何AP间对话。 当漫游发生时,使用隐式通知数据修剪邻居图(以反映实际的邻居AP连接)。
