Publication number: 20230248588Abstract: An absorbent pad, such as a feminine hygiene article, according to the present disclosure comprises superabsorbent polymer particles (2). The superabsorbent polymer particles (2) are surface coated on an outer surface (3) with a coating agent (4), the coating agent (4) being water-soluble. The coated superabsorbent polymer particles (2) comprises an odour inhibiting substance (5) in powder form adhered to and/or mixed with the coating agent (3). The present disclosure also relates to methods of producing the absorbent pad (1).Type: ApplicationFiled: November 12, 2019Publication date: August 10, 2023Applicants: Essity Hygiene and Health Aktiebolag, Essity Hygiene and Health AktiebolagInventor: David Lindqvist

Patent number: 11123234Abstract: A folded absorbent article with an absorbent core having at least two core layers located between a topsheet and a backsheet is provided. The width of a transition between front and intermediate portions of the core is narrower than a width of the rest of the core. A first end portion of the article is folded about a fold line that coincides with or is adjacent the narrow portion of the core. A second end portion of the article is folded about a second and rear transversal fold line. The first end portion may be folded onto a central area and the second end portion may then be folded onto the first end portion, or the second end portion may be folded onto the central area and the first end portion may then be folded onto the second end portion.Type: GrantFiled: December 1, 2017Date of Patent: September 21, 2021Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Kent Vartiainen, David Lindqvist

Publication number: 20120109453Abstract: A system and arrangement for correlating time in different time bases used by interconnected units by timestamping a reference event with a time determined with respect to a first time base. A message unit provides the time to a second interconnected unit that uses a second time base. A translation device is configured to calculate a difference between the time measured by the first time base and in the second time base. The difference is used to translate a time measured by the first clock to a time in a different time base at run time.Type: ApplicationFiled: October 27, 2011Publication date: May 3, 2012Applicant: XINSHU MANAGEMENT L.L.C.Inventors: Lars-Berno Fredriksson, David Lindqvist

Patent number: 7899936Abstract: A device for a modularized system with decentralized and function-executing modules comprising a module with associated clock that is arranged to effect time-stamping of events associated with the system and of reference events selected from among these. The module comprises a memory device for storing the module's time stamps relating to the events noted by the module and to the reference events selected from among these. The module also comprises a microprocessor that generates messages related to the module's stored time stamps. In addition, the module is arranged to transmit the respective generated messages to a time conversion unit via one or more communications links, and the time conversion unit is arranged, after any intermediate storage, to relate the module's respective noted reference event and effected time-stamping to additional reference events and time-stamping introduced into the unit or already in the unit.Type: GrantFiled: July 20, 2005Date of Patent: March 1, 2011Assignee: Xinshu Management, L.L.C.Inventors: Lars-Berno Fredriksson, David Lindqvist

Publication number: 20110008631Abstract: A multi-ply web of flexible material, such as tissue paper or nonwoven material, includes a fluorescent whitening agent. The multi-ply web includes at least two plies being interconnected in one or more adhesive interconnection zones with an adhesive composition including polyvinyl alcohol, a polyaldehyde and an acid catalyst. The polyvinyl alcohol is cross-linked with the polyaldehyde such that the adhesive composition is water insoluble. Also described is a method for improving the bleed fastness of a fluorescent whitening agent of a multi-ply web of flexible material, which includes at least two plies being interconnected in one or more adhesive interconnection zones with an adhesive composition including polyvinyl alcohol. The method includes a step of incorporating a polyaldehyde and an acid catalyst in the adhesive composition so as to cross-link the polyvinyl alcohol with the polyaldehyde such that the adhesive composition is made water insoluble.Type: ApplicationFiled: March 7, 2008Publication date: January 13, 2011Applicant: SCA HYGIENE PRODUCTS ABInventor: David Lindqvist

Publication number: 20070094528Abstract: A run time method correlates time in different time bases used by interconnected units by timestamping a reference event with a time determined with respect to a first time base. The time is provided to a second interconnected unit that uses a second time base. A difference between the time measured by the first time base and in the second time base is determined. The difference is used to translate a time measured by the first clock to a time in a different time base at run time. An arrangement correlates different time bases of interconnected units, and includes a first unit that detects a reference event. A clock determines the reference time of the reference event in a first time base. A message unit sends the reference time to a second interconnected unit. The second interconnected unit uses a second time base, and a translation device correlates time measurements between the first time base and the second time base at run time.Type: ApplicationFiled: October 30, 2006Publication date: April 26, 2007Applicant: Kvaser Consultant ABInventors: Lars-Berno Fredriksson, David Lindqvist
