Publication number: 20220371216Abstract: A knife assembly for cutting a substrate during relative motion between the knife and the substrate, the assembly including a knife having a distal knife blade and a proximal knife shaft attached to a holder rotatable about a first axis perpendicular to the substrate to define a cut direction angle. The holder is also configured to rotate the knife blade about a second axis perpendicular to the first axis to form a notch angle relative to the first axis. The notch angle is preferably automatically infinitely adjustable within a range of angles. The holder may also, optionally, be configured to rotate the knife blade about a third axis perpendicular to a plane defined by the knife blade to adjust an angle of attack of the knife blade relative to the substrate.Type: ApplicationFiled: October 13, 2020Publication date: November 24, 2022Applicant: KONGSBERG PRECISION CUTTING SYSTEMS ASInventors: Matti Damgaard WINTHER, Sondre HUSTVEIT, Simon KVANVIK, Thomas MALME, Satish NAIDU, Lidvar BUDAL, Ivar HOLM, Knut JOHANSEN

Patent number: 9335330Abstract: A method to extract information from samples taken at different times from a mammalian. These samples are analyzed with respect to one or more analytes giving one or more responses, creating one or more response curves. From this/these response curves is/are changes in the responses calculated as slope, curvatures or mathematical functions. This is especially useful for early detection of acute myocardial infarction.Type: GrantFiled: June 10, 2009Date of Patent: May 10, 2016Assignee: Scientific Engineering QEDInventor: Knut Johansen

Patent number: 6862094Abstract: A two-dimensional imaging surface plasmon resonance (SPR) apparatus for optical surface analysis of a sample area on a sensor surface is disclosed. The apparatus comprises a sensor surface layer of a conductive material that can support a surface plasmon, such as a free electron metal, e.g. gold, silver or aluminum, a source of electromagnetic beams of two or more wavelengths that illuminate a two-dimensional surface area from either the front or the backside of the sensor surface layer, and a detector for simultaneous, or pseudo simultaneous, detection of two or more wavelengths of reflected intensities from the two-dimensional surface area, providing two or more two-dimensional images of the surface area, the two-dimensional images being a function of the effective refractive index at each point on the surface area. The two-dimensional images put together result in a color image. The apparatus is suitable for use in biological, biochemical, chemical and physical testing.Type: GrantFiled: March 14, 2001Date of Patent: March 1, 2005Assignee: Spring Systems ABInventor: Knut Johansen
