Patent number: 8586820Abstract: An absorbent article such as a diaper, a pant diaper, a sanitary napkin, an incontinence guard etc., which includes thermochromic fibers. The thermochromic fibers may be incorporated in one or more of the following components of the absorbent article: the inner coversheet, the acquisition layer, the absorbent structure, the outer coversheet or a layer arranged between the outer coversheet and the absorbent structure. The article may alternatively contain a fibrous layer which mainly or entirely contains thermochromic fibers. The thermochromic fibers may be used as wetness indicator, as a fever indicator, as a function control for microorganisms that have been incorporated in the article or for amusement purposes, such as creating color imprints of hands etc.Type: GrantFiled: September 13, 2005Date of Patent: November 19, 2013Assignee: SCA Hygiene Products ABInventors: Morgan Hansson, Robert Torstensson

Patent number: 8324444Abstract: An absorbent article, such as a diaper, a pant diaper, a sanitary napkin, an incontinence guard etc., includes components that are joined together by a bonding pattern. The bonding pattern has color-changing properties triggered by heat and/or pressure exerted during the bonding process, the color-changing properties being either irreversible or reversible. The color-changing properties may be accomplished by thermochromic pigments, thermochromic fibers and/or pressure-sensitive pigments. A laminate is formed from two or more web material layers joined together by a bonding pattern having color-changing.Type: GrantFiled: September 13, 2005Date of Patent: December 4, 2012Assignee: SCA Hygiene Products ABInventors: Morgan Hansson, Robert Torstensson, Henrik Carlén

Patent number: 7875136Abstract: A method for manufacturing an absorbent hygiene article having a plurality of components that are joined together during the manufacturing process. Thermochromic fibres are incorporated in a component web, component or a selected area thereof, said thermochromic fibres being adapted to change colour between a contrasting colour to a less contrasting colour. A colour change of said thermochromic fibres is induced during one step of the manufacturing process and the presence of the thermochromic fibres being in their contrasting state is detected by a detection means. A measure in the process control is actuated in response to the detected presence of thermochromic fibres in their contrasting state.Type: GrantFiled: December 7, 2005Date of Patent: January 25, 2011Assignee: SCA Hygiene Products ABInventors: Robert Torstensson, Morgan Hansson, Henrik Carlén

Patent number: 7697445Abstract: A system and method for autonomous data path verification in a multi-module shelf configuration, such as in a digital cross-connect system, are disclosed. The system generally includes a source port module, a destination module, and optional n-stage network of mapping interface modules. The source port module is configured to reuse transport overhead bytes of received SONET or SDH signals by inserting data path verification data therefor. The destination module is configured to perform autonomous data path verification between the source port module and the destination module by examining the reused transport overhead bytes of the signals received from the source port module. The method generally includes reusing transport overhead bytes by inserting data path verification data into the overhead bytes of signals received by a first module, e.g., a source port module, and transmitting the signals with the data path verification data toward a second module, e.g., a destination port module.Type: GrantFiled: June 5, 2003Date of Patent: April 13, 2010Assignee: Tellabs Operations, Inc.Inventors: Brian L. Yarger, Satish K. Jena, Terrence J. Tanis, Robert Torstensson

Publication number: 20080297325Abstract: A method for associating a reading of a machine readable sensor positioned in an absorbent article, such as a diaper, a diaper of pant type, an incontinence garment, a sanitary napkin, a tampon-like product, a wound or sore dressing, a bed protector, or a similar product, with the identity of a user of the absorbent article. A machine readable identity tag is uniquely associated with the user independently of the absorbent article. Furthermore, the reading of the sensor is performed during the same reading session as a reading of the identity tag. In addition, a system including an absorbent article including a sensor, an identity tag and reading means for performing readings of the sensor and the tag during the same reading session.Type: ApplicationFiled: December 16, 2005Publication date: December 4, 2008Applicant: SCA HYGIENE PRODUCTS ABInventors: Robert Torstensson, Christian Sahlin

Publication number: 20080269704Abstract: An absorbent article, such as a diaper, a pant diaper, a sanitary napkin, an incontinence guard etc., includes components that are joined together by a bonding pattern. The bonding pattern has colour-changing properties triggered by heat and/or pressure exerted during the bonding process, the colour-changing properties being either irreversible or reversible. The colour-changing properties may be accomplished by thermochormic pigments, theromchromic fibres and/or pressure-sensitive pigments. A laminate is formed from two or more web material layers joined together by a bonding pattern having colour-changing.Type: ApplicationFiled: September 13, 2005Publication date: October 30, 2008Applicant: SCA HYGIENE PRODUCTS ABInventors: Morgan Hansson, Robert Torstensson
