    • The invention is addressing the problem of efficient formation and maintenance of piconets with assistance from the master of an already existing piconet. The master of an existing piconet initiates the formation of a new helper piconet by at least two of its slaves. One of the slaves of the existing piconet becomes the master of the newly formed helper piconet and the other slave becomes a slave of the helper piconet. This process can be used to expand the number of Bluetooth devices that can use an Internet access point. It can also be used to permit two slave devices to communicate directly with one another so as not to unnecessarily use bandwidth available through the master. Finally, the method and system could be used to provide a method of efficient hand-off from one piconet to another.
    • 本发明在已经存在的微微网的主机的协助下解决了微微网的有效形成和维护的问题。 现有微微网的主人由其至少两个奴隶启动新的助手微微网的形成。 现有微微网中的一个从站成为新形成的辅助微微网的主机,另一个从站成为辅助微微网的从站。 该过程可用于扩展可以使用因特网接入点的蓝牙设备的数量。 它也可以用于允许两个从设备彼此直接通信,以免不必要地使用通过主设备可用的带宽。 最后,该方法和系统可用于提供从一个微微网到另一个微网的有效切换的方法。

    • A body implantable lead system includes an over-the-wire lead with a longitudinally extending lumen. A hollow stylet having an outer peripheral surface is introduced into the lumen and an annular resilient blood seal within the lumen may be sealingly positioned between the outer peripheral surface of the stylet and the lead to prevent flow of blood beyond the blood seal and into the lumen in a proximal direction. A guidewire is slidably received within the hollow stylet and includes a tip end which may project through the passage at the distal end of the lead such that relative movement of the guidewire and stylet within the lead is enabled while avoiding friction between the blood seal and the guidewire. Either the guidewire or the stylet may be preshaped for proper placement of the lead for engagement with the body tissue and surrounded by a semi-rigid retractable sheath.
    • 身体可植入引线系统包括具有纵向延伸管腔的线上导线。 具有外周面的中空管心针被引入内腔,并且内腔内的环形弹性血液密封件可以密封地定位在探针的外周表面和引线之间,以防止血液流过血液密封件流入腔内 在近端方向。 引导线可滑动地容纳在中空管心针内,并且包括可以在引线的远端处突出通过通道的尖端,使得导线和探针在引线内的相对运动得以实现,同时避免血液密封和 导丝。 引导线或探针可以被预先成形,以便正确地放置引线以与身体组织接合并且被半刚性的可缩回护套包围。
