    • In an example embodiment disclosed herein is an apparatus, comprising a battery, a display, and logic coupled to the battery and display. The logic is configured to determine an amount of remaining energy in the battery, and a current power consumption rate of the apparatus. The logic determines whether the amount of remaining energy is sufficient to operate the apparatus for the duration of the predetermined time period based on the current power consumption rate of the apparatus. The logic is configured to adjust the brightness of the display to enable the device to operate for the duration of the predetermined time period responsive to determining the amount of remaining energy in the battery is insufficient to operate the apparatus for the duration of the predetermined time period based on the current power consumption of the apparatus.

    • A method for characterizing a threaded coupling such as between two tubular members is disclosed. In one embodiment, a threaded connection between a first tubular and a second tubular is considered, where the first tubular has a internally-threaded box structure and the second tubular has outer threads defining a pin structure. A mathematical model of the connection between the two tubulars is generated, and the mathematical model is permuted to reflect application of at least one flexing force to the joint. From the permuted model, a stress/strain distribution of the box and pin structures is derived. A connection fatigue index value is calculated based on the stress/strain distribution. In one embodiment, connection fatigue indices are computed for a variety of connection combinations, such that a user can compare the relative suitability of multiple box/pin combinations to select one that is deemed desirable for a particular use.
    • 公开了一种用于表征诸如两个管状构件之间的螺纹联接器的方法。 在一个实施例中,考虑了第一管和第二管之间的螺纹连接,其中第一管具有内螺纹的箱结构,第二管具有限定销结构的外螺纹。 产生两个管之间的连接的数学模型,并且将数学模型置换以反映至少一个弯曲力对接头的应用。 从排列的模型中,推导出盒和针结构的应力/应变分布。 基于应力/应变分布计算连接疲劳指数值。 在一个实施例中,针对各种连接组合来计算连接疲劳指数,使得用户可以比较多个盒/针组合的相对适合性以选择被认为对特定用途是期望的。

    • A lightweight and compact super-insulation system that is also capable of supporting a high level of compressive load is described. The system utilizes spacers to provide structural support and utilize controlled buckling of a thin protective outer skin supported by spacers to form strong catenary surfaces to protect insulation material underneath. The spacers may comprise an aerogel, or an aerogel may provide insulation separate from the spacer yet contained within the thin outer skin. The system will be useful for thermal management of variety of deep underwater structures such as pipe-in-pipe apparatus, risers or subsea trees for ultra-deep water oil-and-gas exploration.

    • Provided are extendable loop-back passive optical network (PON) and scheduling method and apparatus for the same. The loop-back type PON includes an OLT (optical line terminal) including a wavelength-tunable optical transmitter and a wavelength-locked optical receiver, and an RN (remote node) including an optical coupler/splitter, the optical coupler/splitter receiving optical signals from the wavelength-tunable optical transmitter and splitting the optical signals by wavelength so as to transmit the optical signals to corresponding ONTs (optical network terminals). Each of the ONTs transmits upstream data to the OLT using the same wavelength as the wavelength of the optical signal received from the OLT through the RN. Since the optical network makes use of the TDM and WDM communication schemes, the optical network can be maintained and upgraded at lower cost.
