摘要: A flame detecting method and device are provided to improve the accuracy of flame detection and reduce the possibilities of the false fire alarm. The flame detecting method and device capture a plurality of images of a monitored area; determines whether a moving area image exists in the plurality of images; analyzes at least one of a color model and a flickering frequency of the moving area image to generate a first analyzed result and compares the first analyzed result with a feature of a reference flame image; analyzes at least one of a variation of a location and an area of the moving area image to generate a second analyzed result and compares the second analyzed result with a predetermined threshold; and determines whether the moving area image is a flame image based on results of the comparing steps.

摘要: A smoke detecting method is provided. The smoke detecting method includes steps of (a) capturing a video segment for a object and a background; (b) analyzing if an image of the object is moving; (c) analyzing a chrominance variance of the moving object with a corresponding background; (d) analyzing at least one of an edge blur of the image of the background and a flickering frequency of the moving object with its corresponding background; (e) comparing analyzed results obtained from the steps (b)-(d) to a smoke feature; and (f) determining if the moving object is a smoke.

摘要: A biological safety cabinet comprises a cabinet body, an experiment chamber, a blower, and a soft material chamber. The cabinet body is cuboid and comprises a first elongated side. The experiment chamber is disposed in the cabinet body. The blower impels air in a direction parallel to the first elongated side. The soft material chamber is connected to the blower, wherein air flows from the blower through the soft material chamber and into the experiment chamber.
