Patents by Inventor Ole Magne Johnsen

Ole Magne Johnsen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7154600
    Abstract: A method and an apparatus for automatic analysis of particle size distribution, shape and color. The method includes collection of a particle sample, where the particles are distributed into a substantially monolayer particle curtain to be exposed to a light source for providing imaging and subsequent analysis of the particles. The apparatus has a sampling device that collects samples from the product stream integrated in the system.
    Type: Grant

  • Patent number: 6822736
    Abstract: In a method and a system for automatic analysis of particle size distribution, shape and color, sampled particles are distributed into a substantially monolayer particle stream to be exposed to a light source for providing imaging and subsequent analysis of the particles. The samples are collected manually or automatically and placed in containers provided with identification codes which can be read/typed manually or automatically, recorded optically or electronically and the containers are placed in storage devices or sample magazines which can be connected to a sample distribution device for forming the particle stream. The samples can be collected from various process streams and the containers for these samples can be placed in the same storage device for being analyzed as a series of analyses. The imaging of the particle stream is performed by a camera chosen among several cameras present in the analyzing device according to the particle size distribution of the sample.
