    Abstract: An underground seamless storm shelter for use during severe weather. The storm shelter is comprised of a single piece base formed by a rotational molding process and an impervious, steel plate cover that is secured to the base by a method forming a watertight seal. The cover comprises a steel door that serves as the means of entrance into the shelter. In addition, a ladder is attached to the cover to facilitate entry and exit. The storm shelter has a ventilation system that provides fresh air to the inhabitants. The storm shelter is secured to the ground by a plurality of anchors that are attached to the cover.

    Abstract: The present invention introduces a concept of “smart” ribbons, which use functionally tensioned optical fibers during the manufacture of fiber optic ribbons to create fiber ribbons with controlled geometrical configuration, optimized strain distribution and reduced attenuation. The ribbons may have flat or bowed cross section and be straight along the length or curved in its plane, or twisted unidirectionally, or periodically. These shapes and residual stress-strain state are induced and controlled by using tension functions instead of traditional constant-value tension per fiber during the ribbon manufacture. Further, the present invention reduces signal loss and/or attenuation in ribbon fibers caused by an increase in the strain variation from tensile strain to compressive strain along the length of the individual fibers when ribbons are manufactured, stacked, stranded around a strength member or twisted and bent during cable installation. In a first embodiment of the present invention, either a symmetric or non-symmetric load distribution is applied across the fibers being placed or drawn into a ribbon structure to eliminate or control residual twist in a completed fiber ribbon. Additionally, in the present invention, the load distribution on the fibers of a ribbon can be varied (e.g. periodically changed) along the length of the ribbon to provide a ribbon with the required design characteristics for any particular application. In a second embodiment of the invention, a fiber optic ribbon is made up of a plurality of sub-unit ribbons arranged in substantially the same plane. Each sub-unit ribbon includes a plurality of optical fibers coated by sub-unit matrices.

    Abstract translation: 本发明引入了“智能”带的概念,其在制造光纤带期间使用功能张紧的光纤以产生具有受控几何构型,优化的应变分布和减小的衰减的光纤带。 带可以具有平坦或弯曲的横截面,并且沿着该长度是直的或在其平面上弯曲,或者单向扭转或周期性地扭曲。 这些形状和残余应力应变状态通过使用张力函数来引导和控制,而不是色带制造期间每个纤维的传统恒定值张力。 此外,本发明减少了当色带被制造,堆叠,绞合在强度构件上或绞合时沿着单个纤维的长度的应变变化从拉伸应变变化到压缩应变的增加引起的带状纤维中的信号损失和/或衰减 并在电缆安装期间弯曲。 在本发明的第一实施例中,将对称或非对称的负载分布施加在放置或拉入带状结构中的纤维上,以消除或控制完成的纤维带中的残余扭曲。 另外,在本发明中,带的纤维上的载荷分布可以沿着带的长度改变(例如周期性地改变),以便为任何特定应用提供具有所需设计特征的带。 在本发明的第二实施例中,光纤带由布置在基本相同的平面中的多个子单元带构成。 每个子单元带包括由子单元矩阵涂覆的多个光纤。
