20090116692 | REALTIME OBJECT TRACKING SYSTEM - A real-time computer vision system tracks one or more objects moving in a scene using a target location technique which does not involve searching. The imaging hardware includes a color camera, frame grabber and processor. The software consists of the low-level image grabbing software and a tracking algorithm. The system tracks objects based on the color, motion and/or shape of the object in the image. A color matching function is used to compute three measures of the target's probable location based on the target color, shape and motion. The method then computes the most probable location of the target using a weighting technique. Once the system is running, a graphical user interface displays the live image from the color camera on the computer screen. The operator can then use the mouse to select a target for tracking. The system will then keep track of the moving target in the scene in real-time. | 2009-05-07 |

In one implementation, the first coupling element and the second coupling element can be detachably joined in a coupled state, where the first passage and the second passage form a common passage and/or have (or surround) a common longitudinal axis. The first passage can be configured with a funnel-shaped section that, in the coupled state, the first passage faces the second passage and widens toward the second passage. In addition, the first coupling element may be formed from ceramic material at least on its inner surface in the region of the funnel-shaped section. | 2009-05-07 |
