    • A non-invasive tissue oxygenation system for accelerating the healing of damaged tissue and to promote tissue viability is disclosed herein. The system is comprised of a lightweight portable electrochemical oxygen concentrator, a power management system, microprocessors, memory, a pressure sensing system, an optional temperature monitoring system, oxygen flow rate/oxygen partial pressure monitoring and control system, a display screen and key pad navigation controls as a means of providing continuous variably controlled low dosages of oxygen to a wound site and monitoring the healing process. A kink resistant oxygen delivery tubing, whereby the proximal end is removably connected to the device and the distal end with holes or a flexible, flat, oxygen-permeable tape is positioned at or near the wound bed as a means of applying near 100% pure oxygen to the wound site. The distal end of the tube is in communication with the electrochemical oxygen concentrator and wound monitoring system to communicate oxygen partial pressure and, where appropriate, temperature information. A moisture absorbent dressing is positioned over the distal end of the tubing at the wound site and a reduced moisture vapor permeable dressing system is positioned whereby covering the moisture absorbent dressing, distal end of tubing and wound site creating a restricted or occluded airflow enclosure. The restricted airflow enclosure allows the out-of-the-way control and display unit to provide a controlled hyperoxia and hypoxia wound site for accelerated wound healing.

    • An intelligent traffic redirection system performs global load balancing for Web sites located at mirrored data centers. The system relies on a network map that is generated continuously for the user-base of the entire Internet. Instead of probing each local name server (or other host) that is connectable to the mirrored data centers, the network map identifies connectivity with respect to a much smaller set of proxy points, called “core” (or “common”) points. A core point then becomes representative of a set of local name servers (or other hosts) that, from a data center's perspective, share the point. Once core points are identified, a systematic methodology is used to estimate predicted actual download times to a given core point from each of the mirrored data centers. Preferably, ICMP (or so-called “ping” packets) are used to measure roundtrip time (RTT) and latency between a data center and a core point. Using such data, an average latency is calculated, preferably using an exponentially time-weighted average of all previous measurements and the new measurement. A similar function is used to calculate average packet loss. Using the results, a score is generated for each path between one of the data centers and the core point, and the score is representative of a file download time. Preferably, the score is generated by modifying an average latency with a penalty factor dependent on the time-weighted average loss function. Whichever data center has the best score (representing the best-performing network connectivity for that time slice) is then associated with the core point.
    • 智能流量重定向系统对位于镜像数据中心的网站执行全局负载平衡。 系统依赖于为整个互联网的用户群连续生成的网络地图。 而不是探测可连接到镜像数据中心的每个本地名称服务器(或其他主机),网络映射标识了相对于称为“核心”(或“公共”)点的更小的一组代理点的连接性。 因此,核心点将成为一组本地名称服务器(或其他主机)的代表,从数据中心的角度来看,它们共享这一点。 一旦识别出核心点,就使用系统方法来估计从每个镜像数据中心到给定核心点的预测实际下载时间。 优选地,ICMP(或所谓的“ping”分组)被用于测量数据中心和核心点之间的往返时间(RTT)和等待时间。 使用这样的数据,优选地使用所有先前测量和新测量的指数时间加权平均值来计算平均延迟。 使用类似的功能来计算平均丢包。 使用结果,为数据中心之一和核心点之间的每个路径生成分数,分数代表文件下载时间。 优选地,通过依赖于时间加权平均损失函数的惩罚因子修改平均延迟来产生得分。 然后,与核心点相关联的数据中心具有最佳分数(表示该时间片的最佳性能的网络连接)。

    • A multistage optical amplifier is controlled to compensate for the effect of amplified spontaneous emission (ASE) by a method comprising the following steps. Optical input and output signals to a first gain stage are detected, and the drive current to the first gain stage is controlled in dependence on the optical input signal to the first gain stage. Optical input and output signals to a last gain stage are detected, and the drive current to the last gain stage is controlled to maintain the output power of the last gain stage substantially constant. The effect of ASE in the first gain stage is compensated for by applying a correction factor based on the ASE of the first gain stage and the output power of the first gain stage. The drive current supplied to the first gain stage is controlled to zero in on an error signal of the general form: (Total Power at B−Stage 1 ASE)−(A+Stage 1 Gain) where Total Power at B is the power of the output signal from the first gain stage, and A is the input signal of the first gain stage. Furthermore the drive current supplied to the last gain stage is controlled to zero in on an error signal of the general form: (Total Power at E−Stage 2 ASE)−(D+Stage 2 Gain) where Total Power at E is the power of the output signal from the last gain stage, and D is the input signal of the last gain stage. In this method the correction factor is calibrated in the gain control mode and is subsequently applied in the power control mode, and this therefore simplifies the calibration procedure.
    • 控制多级光放大器以通过包括以下步骤的方法来补偿放大的自发发射(ASE)的影响。 检测到第一增益级的光输入和输出信号,并且根据到第一增益级的光输入信号来控制到第一增益级的驱动电流。 检测到最后一个增益级的光输入和输出信号,并控制到最后一个增益级的驱动电流,以保持最后增益级的输出功率基本恒定。 ASE在第一增益级中的作用通过应用基于第一增益级的ASE和第一增益级的输出功率的校正因子来补偿。 提供给第一增益级的驱动电流在一般形式的误差信号上被控制为零:<?in-line-formula description =“在线公式”end =“lead”?>(B处的总功率 - 1号增益) - (A +阶段1增益)<?in-line-formula description =“在线公式”end =“tail”?>其中B处的总功率是第一个输出信号的功率 增益级,A为第一增益级的输入信号。 此外,提供给最后一个增益级的驱动电流在一般形式的误差信号上被控制为零:<?in-line-formula description =“在线公式”end =“lead”?>(总功率 E阶段2 ASE) - (D +阶段2增益)<?in-line-formula description =“在线公式”end =“tail”?>其中E处的总功率是来自 最后一个增益级,D是最后一个增益级的输入信号。 在该方法中,校正因子在增益控制模式下被校准,随后在功率控制模式中被应用,因此简化了校准过程。
