    • Systems and methods are provided for detecting a movement of an object marked with a marker. The system includes a sensor configured to capture a first image of the marker and to capture a second image of the marker after the first image, each of the first and second images having pixels each having a visual intensity. A controller is configured to compare the first image and the second image by comparing the visual intensity of each of the pixels of the first image and the second image, determine an area of overlap between the first image and the second image based on the comparison, calculate a change in position of the marker in the second image relative to the marker in the first image based on the area of overlap, and detect the movement of the object based on the change in position of the marker.
    • 提供了用于检测标记有标记的对象的运动的系统和方法。 该系统包括被配置为捕获标记的第一图像并且在第一图像之后捕获标记的第二图像的传感器,每个第一和第二图像具有各自具有视觉强度的像素。 控制器被配置为通过比较第一图像和第二图像的每个像素的视觉强度来比较第一图像和第二图像,基于该比较来确定第一图像和第二图像之间的重叠区域, 基于重叠区域计算相对于第一图像中的标记的第二图像中的标记的位置的改变,并且基于标记的位置的改变来检测对象的移动。

    • A vertical connection apparatus for connecting a pipeline to a subsea structure comprises a guide funnel for controlling the position of the pipeline relative to the subsea structure; a moveable barrier and a attachment region for a drive mechanism; the moveable barrier is operable between an open position in which the pipeline can pass through the guide funnel and a closed position in which the barrier prevent the end of the pipeline passing through the end of the guide funnel. A tool with a drive mechanism can be attached between the pipeline and guide funnel to manipulate the pipeline into a connectable position. A clamp connector secures the connection between the pipeline and subsea structure conduit.
    • 用于将管道连接到海底结构的垂直连接装置包括用于控制管道相对于海底结构的位置的导向漏斗; 可移动屏障和用于驱动机构的附接区域; 可移动屏障可操作在管道可以穿过导​​向漏斗的打开位置和封闭位置之间,其中阻挡物阻止管道的端部通过引导漏斗的端部。 具有驱动机构的工具可以安装在管道和引导漏斗之间,以将管道操纵成可连接的位置。 夹紧连接器固定管道和海底结构导管之间的连接。

    • A retraction apparatus and method are provided including slider assemblies for being slidably connected to a retractor body with end portions of the slider assemblies disposed within a central retractor opening. A retractor blade is slidably connected to one of the slider assembly end portions such that the depth of the retractor blade can be readily adjusted. Once the retractor blade is at the desired depth within the incision, a handle is pivoted to a locked position to fix the blade relative to the slider assembly. A cantilever lock between the blade and the slider assembly pivots the blade relative to the slider assembly to fix the blade thereto. In one form, the retractor body has a substantially flat surface configured to be placed adjacent a bone and slide connections which position slider assemblies such that the connected blades avoid contact with the bone during retraction.
    • 提供了一种缩回装置和方法,包括滑动组件,滑块组件可滑动地连接到牵开器主体,滑块组件的端部设置在中央牵开器开口内。 牵开器叶片可滑动地连接到滑块组件端部中的一个,使得能够容易地调节牵开器叶片的深度。 一旦收缩器叶片处于切口内的所需深度,则手柄枢转到锁定位置以相对于滑块组件固定刀片。 刀片和滑块组件之间的悬臂锁相对于滑块组件枢转刀片以将刀片固定在其上。 在一种形式中,牵开器主体具有基本上平坦的表面,其构造成邻近骨头放置并滑动连接件,其将滑动器组件定位成使得连接的叶片避免在收回期间与骨骼接触。
