Hakan Erik Roos 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: 11179725
    Abstract: A self-adhesive layered septum is disclosed. In one example, the septum includes a first outer layer including a thermoplastic elastomer such as a styrenic block copolymer, containing styrene ethylene butylene styrene (TPE-SEBS) capable of closing at least partially an aperture formed when a needle is inserted through the layer; an adhesive second layer for adhering the septum to a mouth area of a well or container to which the septum is attachable; and a thermoplastic third layer between the first and second layers, thermobonded to the first layer and providing better adherence for the adhesive layer. The first layer includes a recess and a vent, which reduce pressure differentials in use, but together with the third layer minimize evaporation through the septum.
    Type: Grant

  • Patent number: 9891192
    Abstract: A system and method for generating a digital image in fluorescence gel imaging is disclosed. The method includes providing a gel sample and placing the gel sample on a flat panel detector having array of photodiodes and transistors that collect light generated from the gel sample. The gel sample is illuminated using a light source integrated into the flat panel imaging system and light emitted by the gel sample responsive to an excitation of the gel sample by light provided by the light source is then collected, with the light emitted by the gel sample being collected by the array of photodiodes of the flat panel detector and converted to electric charges to generate light data. The light data is then processed to generate a digital image of the gel sample.
