摘要： A laboratory-scale device for assisting in the simulation of heat setting conditions includes a pair of laterally spaced-apart flexible heat-resistant cords (e.g., formed of aramid fibers) tensioned between forward and rearward rigid cross-support bars. At least one rigid tensioning bar is provided parallel to the support cords and extending between the cross-support bars so as to maintain the desired tension on the flexible heat-resistant cords. The tensioning bar thus allows for manual or automated lateral winding of the synthetic heat-settable fibers or yarns about the spaced-apart heat-resistant cords during preparation of the device for a laboratory test run. The tensioning bar may thereafter be removed once the device has been secured in position with the laboratory heat-setting oven. In such a manner, therefore, various effects on heat-setting conditions simulating can be investigated.

摘要： A preferred embodiment of the present invention provides a cell site base station configuration for a wireless communications system that makes use of a sectorized base station co-located with an omnidirectional base station. The sectorized base station has a sectorized antenna system and the omnidirectional base station has an omnidirectional antenna. The configuration may also include a controller that monitors the base station for communications links subject to adverse conditions and reassigns any such links to the omnidirectional base station. The adverse conditions monitored for may include multiple fade, equipment failure and a lack of available channels. The controller may also monitor the omnidirectional base station for links that can be moved to the sectorized base station and reassign any such links to the sectorized base station. The configuration may also include a network that interconnects the sectorized base station, the omnidirectional base station and the controller.
摘要翻译：本发明的优选实施例提供了一种利用与全向基站同时定位的扇区化基站的无线通信系统的小区站点基站配置。分段基站具有扇区天线系统，全向基站具有全向天线。该配置还可以包括控制器，该控制器监视基站对于处于不利条件的通信链路，并将任何这样的链路重新分配给全向基站。监测的不利条件可能包括多次褪色，设备故障和缺乏可用的通道。控制器还可以监控全向基站，以获得可移动到扇区化基站的链路，并将任何这样的链路重新分配给扇区化的基站。该配置还可以包括互连分割的基站，全向基站和控制器的网络。
