    摘要： The present disclosure describes an endotracheal tube for a child, the tube having a balloon mounted near the distal end of the tube. The tube has a ventilation lumen and an inflation line used to inflate the balloon. The balloon is mounted to the tube at a lower mounting point and an upper mounting point. The upper mounting point is above the level of the vocal cords. The balloon has a lower and upper diameter when inflated, and the upper diameter is from 1.1 to 1.5 times larger than the outer diameter of the tube.

    摘要： A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that an extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station. Next the preformed composite laminate travels into a pultrusion die where the extended “groupings of fiber filaments” are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die. The composite laminate continues to be pulled by grippers that then feed it into a gantry CNC machine that is synchronous with the pull speed of the grippers and where computerized machining, drilling, and cutting operations take place. This entire method is accomplished automatically without the need for human operators.

    摘要： Methods and systems provide a geographical network alarm viewer (GNAV) application that receives, tracks, aggregates, reports, and maps data associated with cable telephony services outages occurring in a cable services network. The GNAV application integrates network map data and identification information associated with customer locations, equipment, and associated network alarm data from a network operations center. All customer location addresses associated with individual network alarms are located and mapped on a geographical network map. Because the alarms are received, tracked, aggregated, reported, and mapped in real-time, service personnel may respond to network outages in a more efficient manner, and service technicians and service vehicles may be directed to repair service outages based on more accurate location and service outage timing data.

    摘要： A method of inserting z-axis reinforcing fibers into a multi-layer composite laminate. Layers of material made up of z-axis fiber and y-axis fibers are automatically transported into a z-fiber deposition machine having a housing with upper and lower surfaces. Z-axis apertures are formed in the respective upper and lower surfaces. An elongated solid rod having a tapered front tip is aligned in close proximity to the aperture in the bottom surface. The rod is first rotated by a motor and then actuated upwardly completely through the thickness of the layer of x-y material by an actuator. A first hollow tube having a z-axis is axially aligned with the aperture in the top surface and a fiber bundle is threaded downwardly through a first hollow tube to a position adjacent its bottom end. The z-fiber deposition machine has structure to feed a predetermined length of the fiber bundle downwardly through the first hollow tube so that it follows the pathway in the x-y material formed by the rod which is now withdrawn downwardly through the aperture in the bottom wall. The z-axis fiber is thus deposited into the x-y material. The top end of the z-axis fiber is then severed and the x-y material is then advanced a predetermined distance to complete the cycle and is, thus, set to be repeated.

    摘要： A scheme for extending the life of a drum maintenance unit that applies a release agent to the surface of a transfer drum in a phase change ink inkjet printer determines a release agent usage ratio based on an ink coverage percentage for each print. The release agent usage ratios for each print are accumulated, and each time the release agent ratio accumulation value has an integer change a maintenance counter in the drum maintenance unit is decremented by one from an initial nominal number of prints to produce a number of prints remaining. Once the number of prints remaining reaches a specified low value, the maintenance counter may be decremented by one for each additional print to allow for variability in the amount of release agent consumed per print from projected values. As a result depending upon a particular customer usage profile a drum maintenance unit having a nominal life of 30,000 prints, for example, may be extended by over 40%.

    摘要翻译： 用于延长相变墨水喷墨打印机中的转印鼓表面上施加脱模剂的滚筒维护单元的使用寿命的方案根据每个印刷品的油墨覆盖率确定脱模剂使用率。 每个印刷品的脱模剂使用率被累积，并且每次脱模剂比例累加值具有整数变化时，滚筒保养单元中的维护计数器从初始标称打印数量减1，以产生剩余的打印数量 。 一旦剩余的打印数量达到指定的低值，维护计数器可以针对每个附加打印递减1，以允许每个打印机从投影值消耗的脱模剂量的变化。 因此，取决于特定客户使用情况，例如，具有30,000印刷品的标称寿命的滚筒维护单元可以延长超过40％。
