Publication number: 20200094042Abstract: A garment worn by the patient is provided. The garment has a first module electrically connected to a second module. The first module has a first sub-control unit electrically connected to a first electrode and a second electrode placed at a first muscle of the patient and a third electrode and a fourth electrode placed at a second muscle. The sub-control unit is electrically connected to a master unit. The first muscle is stimulated with a first stimulation signal without shortening the first muscle by sending the first stimulation signal to the first electrode placed at the first muscle. The stimulation of the first muscle relaxes the second muscle. A measuring unit (U1) of the master unit determines a first current value flowing from the first electrode through the first muscle to the second electrode and sends the first current value to a central processing unit (CPU).Type: ApplicationFiled: November 26, 2019Publication date: March 26, 2020Inventors: Lars Dernebo, Fredrik Lundqvist

Publication number: 20090099354Abstract: The present invention provides a method for extracting polymeric pentose, preferably xylan, from a polymeric pentose containing liquid/slurry, preferably black liquor, comprising the following steps: a) providing a polymeric pentose containing liquid/slurry; b) concentrating the polymeric pentose by membrane separation of a said polymeric pentose containing liquid/slurry; and c) adding alcohol to the concentrate obtained in step b) and subsequently acidifying said concentrate obtained in step b) for precipitating polymeric pentose whereby a polymeric pentose product, or an intermediate polymeric pentose product, is obtained. In this above way polymeric pentose, e.g. xylan, is separated whereby the use of methanol (less lignin must be kept in solution) and acid (less acid which buffers the pH-decrease) become much lower.Type: ApplicationFiled: February 2, 2007Publication date: April 16, 2009Applicant: STFI-PACKFORSK ABInventors: Peter Axegard, Karin Lindgren, Olof Dahlman, Per Tomani, Fredrik Lundqvist

Patent number: 5546435Abstract: The invention relates to an arrangement for carrying out leak detection of a fuel assembly for a pressurized-water nuclear reactor. A substantially vertical hollow mast means open in both ends houses the fuel assembly to be examined. The fuel assembly is drawn to the inside of the mast means from its lower side. The part of the mast means housing the fuel assembly is lifted to a position in which the fuel assembly is provided near but below the water surface of water inside the nuclear reactor. Water is sucked from a position inside the mast means above the fuel assembly. A gas separating means separates gases present in water sucked from the inside of the mast means. The separated gas is analyzed in a gas analyzing means regarding its amount of gaseous fission products.Type: GrantFiled: November 16, 1994Date of Patent: August 13, 1996Assignee: ABB Atom ABInventors: Per Collin, Roland Deleryd, Roland Ivars, Fredrik Lundqvist, Norman R.
