摘要： A method of operation of a network transport system includes: determining a congestion mode based on a total bandwidth request meeting or exceeding a bandwidth threshold, where the congestion mode indicates a level of network traffic and the total bandwidth request is a sum of all bandwidth requests for accessing the network; calculating a fixed information rate schedule grant based on a fixed information rate list to create a bandwidth grant for a fixed information rate request; calculating a low latency schedule grant based on a low latency list to create the bandwidth grant for a low latency request; calculating a main schedule grant for allocating an available bandwidth based on the congestion mode, where the main schedule grant is calculated using a weighted maximum-minimum fairness method when the congestion mode indicates congestion; and generating a grant packet for defining a transmission schedule of a first network unit.

摘要： A robotic arm assembly is provided comprising a driving mechanism including a rotor which is rotatable relative to a stator. The rotor is coaxially rotatable about a columnar shaft having a substantially hollow central longitudinal axis. A first arm having proximal and distal pivotal ends is rigidly mounted on the rotor such that the first arm is drivable to rotate by the driving mechanism. A proximal pivotal end of a second arm having proximal and distal pivotal ends is pivotally connected to the proximal pivotal end of the first arm. A first timing pulley is mounted coaxially onto the columnar shaft, and a second timing pulley which is spaced from the first pulley is drivable to rotate together with rotation of the first arm. A timing belt connects the first and second timing pulleys and is operative to rotate the second arm relative to the first arm as the first arm is driven to rotate by the driving mechanism, such that the distal pivotal ends of the first and second arms are configured to always lie along a substantially straight line.

摘要： An apparatus, which performs a plasma process on a target substrate by using plasma, includes first and second electrodes in a process chamber to oppose each other. An RF field, which turns a process gas into plasma by excitation, is formed between the first and second electrodes. An RF power supply, which supplies RF power, is connected to the first or second electrode through a matching circuit. The matching circuit automatically performs input impedance matching relative to the RF power. A variable impedance setting section is connected to a predetermined member, which is electrically coupled with the plasma, through an interconnection. The impedance setting section sets a backward-direction impedance against an RF component input to the predetermined member from the plasma. A controller supplies a control signal concerning a preset value of the backward-direction impedance to the impedance setting section.
