    • A multiple lumen catheter having a soft, tapered multiple lumen distal tip for insertion into a body vessel. One of the lumens is sized to pass over a guidewire such that the catheter can be inserted into the body vessel using the Seldinger technique. At least one medical implement lumen is used for placement or positioning of a biomedical sensor or other medical implement. For example, at least one optical fiber passing through the medical implement lumen may transmit and receive light at the distal tip for measuring oxygen saturation of the blood. The catheter may have a cylindrical catheter body to which the soft distal tip attaches. The soft tip reduces the possibility of vessel or tissue puncture and abrasion. The tip is constructed of a soft plastic or pliable material that yields easily when force is applied. For example, the tip may be made of a softer material than the catheter body, or if made of the same material, the tip can be configured with thinner walls or a higher air-to-material ratio cross-section. Various geometrical configurations and combinations of materials can be used to decrease the flexible resistance of the tip to an applied load. One particular useful application for the catheter of the present invention is as a central venous catheter equipped with fibers for measuring oximetry. The fibers extend to the distal end of the tip and are preferably secured therein with minimal adhesive so as to limit the stiffness added to the tip. One particular useful construction is to secure the fibers within the medical implement lumen using adhesive only along a length of between about 0.5-3.5 mm.
    • 多腔导管,其具有用于插入体容器中的柔软的锥形多腔远端。 其中一个管腔的大小适于穿过导丝,使得导管可以使用Seldinger技术插入体内容器。 至少一个医疗器械腔用于生物医学传感器或其他医疗器具的放置或定位。 例如,穿过医疗器具内腔的至少一根光纤可以在远侧末端传送和接收光,以测量血液的氧饱和度。 该导管可具有一个圆柱形导管主体,软远端尖端附着在该主体上。 软尖端降低了血管或组织穿刺和磨损的可能性。 尖端由软塑料或柔韧材料构成,当施加力时容易产生。 例如,尖端可以由比导管主体更软的材料制成,或者如果由相同的材料制成,则尖端可以被配置为具有更薄的壁或更高的空气 - 材料比的横截面。 可以使用各种几何构型和材料的组合来降低尖端对施加的负载的柔性电阻。 用于本发明的导管的一个特别有用的应用是配备有用于测量血氧定量的纤维的中心静脉导管。 纤维延伸到尖端的远端,并且优选地以最小的粘合剂固定在其中,以便限制添加到尖端的刚度。 一个特别有用的结构是使用粘合剂将纤维固定在医疗器械腔内,只有约0.5-3.5毫米之间的长度。

    • Systems and methods are disclosed to calculate the hue angle of image data. One system includes at least one input channel, an octant determining unit, an angle determining unit, and an angle offset unit. Each input channel receives chroma components of image data. The octant determining unit determines which octant a given image data occupies. The angle determining unit determines a hue angle of the given image data within an octant. The angle offset unit adjusts the hue angle for the image data according to the octant the image data was determined to occupy.
    • 公开了系统和方法来计算图像数据的色调角。 一个系统包括至少一个输入通道,八分圆确定单元,角度确定单元和角度偏移单元。 每个输入通道接收图像数据的色度分量。 八分圆决定单元确定给定图像数据占据哪个八分圆。 角度确定单元确定在八分圆内的给定图像数据的色调角。 角度偏移单元根据确定占据的图像数据的八分圆度来调整图像数据的色调角。

    • A fish lure that alternately dives and surfaces has a hollow body through which water flows as the lure is drawn through water on a line, and an air catching means such as a skirt on the trailing end of the body. The trailing end can be made of a material relatively heavier than water and can be flared to produce an air-retardation low-pressure area at the trailing end. When the air catching means holds water only, the lure is directed upwards to the surface, causing ingestion of air. The ingested air trapped in the air catching means offsets the trailing end weight and causes the lure to tilt downwards temporarily, until the air is lost. The alternating effect may be enhanced by movable-body noisemakers attached within the hollow body and having weighted balls that roll fore and aft as the lure tilts. The variations in lure depth, bubble emission and in emitted sounds due to variations in tilt and air content make the lure especially interesting to fish.
    • 鱼类诱使交替潜水和表面具有中空的身体,当诱饵通过水线在水线上流动时,水流动,以及空气捕获装置,例如身体后端的裙部。 后端可以由比水更重的材料制成,并且可以被扩张以在后端产生空气延迟低压区域。 当空气捕捉装置仅保持水时,诱饵向上指向表面,从而摄入空气。 捕获在空气捕获装置中的摄取的空气抵消尾端重量并使诱饵临时向下倾斜,直到空气流失。 交替效应可以通过附接在中空体内的移动体噪声增强器,并且具有当诱饵倾斜时前后滚动的加权球。 由于倾斜和空气含量的变化,诱饵深度,气泡发射和发出的声音的变化使得诱饵特别有趣。
