TH52578B - A method for creating a shadow of a liquid container and a kit for that method. - Google Patents

Abstract

The invention involved a method and a set of equipment for creating silhouettes for liquid containers. Where the light-emitting unit (2) is provided to allow light to be emitted and beamed onto the container (B), and the photoreceptor (3) is provided to Receive light transmitted through such a container. The purpose of this invention is to provide a method and a set of equipment for creating The silhouettes of the liquid containers, the method and the kits, ensure reliable detection of Surface of the contained liquid In containers or foreign matter mixed in liquids or appearing in containers or materials forming a container, not only in a transparent container but also in cases where the container is colored. To a dark color such as black, dark green or dark brown, or if The container has a texture that is Ice flakes or in case The liquid contained in the container is dark in color. To achieve This purpose In line with this invention, the light emitting unit (2) emits light close to infrared, or the light receiving unit (3) receives light close to infrared to create a shadow image of the container (B).

Claims (2)

1. A method for creating a shadow of a liquid container, which consists of a process of Light emission and exposure onto the container (B) by the light emitting unit (2), the exposure transmitted through the container by the photoreceptor (3) and the container shadow projection based on the news. Message about the receiver that was sent It is characterized by the said light emitting unit (2) to emit and emit nearby light. With infrared as light For creating a shadow image for the container (B). 2. Methods consistent with claim 1, which is designated
