    • A fiber optic drop ribbon is described that can be attached to structures, such as the walls of multi-dwelling units (MDUs), for connecting subscribers to a fiber optic communications network. A number of coated optical fibers are supported by a backing strip of the article having a first and second surface. The first surface is attached to the structure, and the optical fibers are attached to the second surface. A cover strip attaches to the second surface of the backing strip to cover the optical fibers. The cover strip may be removable to provide access to the optical fibers and may reattach to the backing strip following removal. Associated systems and methods are also provided that may include additional components, such as furcation sections, furcation splints, and fiber trays, to facilitate the installation of the article and the connection of subscribers to the fiber optic network.
    • 描述了可以连接到诸如多住宅单元(MDU)的墙壁的结构的光纤色带,用于将用户连接到光纤通信网络。 许多涂覆的光纤由具有第一和第二表面的制品的背衬条支撑。 第一表面附接到结构,并且光纤附接到第二表面。 覆盖条附着到背衬条的第二表面以覆盖光纤。 盖带可以是可移除的以提供对光纤的访问,并且可以在移除之后重新连接到背衬带。 还提供了相关的系统和方法,其可以包括附加部件,例如分叉部分,分叉夹板和纤维托盘,以便于物品的安装和用户连接到光纤网络。

    • A process controller with power outage analysis capability uses a real time clock generator powered by an uninterruptible power source for providing a real time reference which is used to measure the actual duration of a process controller disabling power outage. A non-volatile memory is also powered by the uninterruptible power source and is used to store the maximum allowable outage time limit for a particular process being controlled. The clock generator is initialized at the start of the power outage by a power outage detector which provides an early warning of an imminent power outage. After the power is restored to the controller, a digital computer used in the process controller compares the actual power outage time as represented by the accumulated clock time with allowable power outage time limit stored in the memory and is arranged to provide a first process control sequence if the actual power outage time is less than the maximum allowable time and a second process control sequence if the actual power outage time is greater than the maximum allowable time.
    • 具有停电分析功能的过程控制器使用由不间断电源供电的实时时钟发生器,用于提供实时参考,用于测量过程控制器禁用停电的实际持续时间。 非易失性存储器还由不间断电源供电,并用于存储被控制的特定过程的最大允许停电时间限制。 时钟发生器在断电开始时被停电检测器初始化,该断电检测器提供即将发生的断电的早期警告。 在电源恢复到控制器之后,在过程控制器中使用的数字计算机将由累积时钟时间表示的实际停电时间与存储在存储器中的允许停电时间限制进行​​比较,并且被布置成提供第一过程控制序列 如果实际断电时间小于最大允许时间,则实际断电时间大于最大允许时间时的第二过程控制序列。
