  • Patent number: 10341026
    Abstract: An optical bus system (1) having a start-up state and at least one operating state is disclosed. The optical bus system (1) includes a mechanical support structure (21) arranged to receive and hold a master module (2) having a downstream optical interface (3) and a set of slave modules (6) each having an upstream optical interface (7) and a downstream optical interface (8). The modules are attached to the mechanical support structure (21) such that optical interfaces of adjacent modules are aligned and in close proximity to each other in order to enable optical communication (24, 25) between adjacent modules. Each slave module (6) is further provided with circuitry to form one or two shunting signal paths (30, 31) depending on operating state after an addressing procedure is completed in the start-up state. Hereby, it is e.g. possible to realize a robust and cost-efficient optical bus system with high bandwidth capability.

  • Patent number: 10330164
    Abstract: A coupling assembly for a driveline of a motor vehicle comprises a first shaft; a second shaft; a coupling which can selectively drivingly connect or disconnect the first shaft and the second shaft; a brake for braking the second shaft relative to a stationary component; and an actuating device for actuating the coupling and the brake. The actuating device comprises a ramp mechanism having a first ring which is axially supported relative to the stationary component, and a second ring which is axially movable relative to the first ring when one of the first and second rings is rotated relative to another one of the first and second rings.

  • Publication number: 20140187490
    Abstract: A method of treating functional dyspepsia and/or irritable bowel syndrome in mammals in need of treatment is disclosed herein. The method comprises administering to the mammal a formulation by inhalation, wherein the formulation avoids first pass metabolism of the active ingredient. The method comprises administering a formulation by pulmonary inhalation comprising a diketopiperazine and a glucagon-like peptide (GLP-1), analog, ROSE-010.

  • Patent number: 6348447
    Abstract: The invention relates to the new use of gastrointestinal peptide hormones selected from the class consisting of glucagon-like peptide-1 (GLP-1) and derivatives thereof having anti-secretory effects and smooth muscle relaxatory properties in the gastrointestinal tract for the manufacture of a pharmaceutical composition for the treatment of functional dyspepsia and/or irritable bowel syndrome. The invention also relates to a pharmaceutical composition comprising a combination of at least one member selected from said class consisting of GLP-1 and derivatives thereof with one or more other gastrointestinal peptide hormone(s) or derivative(s) thereof together with pharmacologically acceptable additives and to a method of treating functional dyspepsia or irritable bowel syndrome or both by administering an effective amount of at least one member of said class consisting of GLP-1 and derivatives thereof having effects and properties as mentioned above.

  • Patent number: 4362222
    Abstract: An acoustical system for damping and absorption of sound in rooms to provide a sound damping even at very low frequencies, e.g. 50 Hz, and simultaneously improve speech comprehension in the entire room by reduction of the resonance time. The acoustic absorption can be varied to vary the resonance time over the entire part of the frequency area. The sound absorbents 14 in the form of plates, mats or similar constructions, are arranged at an angle in at least one corner area 11 formed by the walls 12 and ceiling 13 of the room. In the corner area 11 behind the absorbent 14, an air volume is trapped so that the absorbent due to the sound influence has a membrane effect. The inclination and position of each absorbent 14 can be varied individually or in groups.
