Filed: 2009-07-06
Abstract: Moulding is formed by first making a longitudinally extending cut in the bottom wall of a con-ventional eavestrough in order to separate the eavestrough into two segments. The inner portion of the bottom wall is then attached to the exterior wall of a building beneath its eaves or elsewhere such that the back wall of the eavestrough projects outwardly. The front wall of the eavestrough is then hung from the projecting back wall so that it extends downwardly and inwardly toward the exterior wall of the building. The eavestrough is cut by means of a machine having a guide plate and a pair of cutting wheels. The guide plate has an opening of a shape similar to that of the cross--section of the eavestrough but slightly larger so that as the eavestrough is fed through the opening it is guided by the guide plate. The cutting wheels are positioned such that after the eavestrough exits from the opening, its bottom wall passes between the wheels where it is cut.

IPC: G08B13/196
Filed: 2008-02-08
Abstract: Embodiments of the present invention provide a method and a system for an alyzing and learning behavior based on an acquired stream of video frames. O bjects depicted in the stream are determined based on an analysis of the vid eo frames. Each object may have a corresponding search model used to track a n object's motion frame-to-frame. Classes of the objects are determined and semantic representations of the objects are generated. The semantic represen tations are used to determine objects' behaviors and to learn about behavior s occurring in an environment depicted by the acquired video streams. This w ay, the system learns rapidly and in real-time normal and abnormal behaviors for any environment by analyzing movements or activities or absence of such in the environment and identifies and predicts abnormal and suspicious beha vior based on what has been learned.

Filed: 2008-01-17
Abstract: The present inventors conducted dedicated studies, and as a result discovered that propionic acid bacteria fermentation products have a preventive/therapeutic effect on functional gastrointestinal disorders in in vitro tests and tests using patients with irritable bowel syndrome, and completed the present invention. Specifically, the present inventors discovered, in in vitro tests, that the products have an effect of increasing the intestinal contraction frequency without changing the intestinal contractile force in a distal colon-specific manner.  Moreover, effects of improving the defecation condition, general abdominal condition, and health-related QOL in patients with irritable bowel syndrome were also found. Furthermore, propionic acid bacteria fermentation products can be taken in large amounts. Therefore, the propionic acid bacteria fermentation products can be expected to have an effect of preventing/treating functional gastrointestinal disorders safely.
