Patent number: 10973710Abstract: Absorbent article including a chassis and fastening tab. The fastening tab includes a carrier, a first fastener having first male fastening elements, and a second fastener. The second fastener includes a backing with first and second opposing surfaces, with second male fastening elements on the first surface. A first portion of the second surface of the backing is connected to the carrier, and a second portion of the second surface of the backing is attached to the topsheet side of the chassis. The carrier is attached to the backsheet side of the chassis. Some fastening laminates, before attachment to the article, have the second portion of the second fastener folded over to face the first portion of the second fastener. Other laminates have the second fastener positioned with its first surface toward the carrier and attached to the carrier with a film.Type: GrantFiled: November 17, 2015Date of Patent: April 13, 2021Assignee: 3M Innovative Properties CompanyInventors: Mark A.

Patent number: 10967624Abstract: The article includes a thermoplastic layer having opposing first and second side edges and a first surface bearing male fastening elements. The thermoplastic layer is plastically deformed and has a retardance profile having an average retardance along a line from the first edge to a location 500 micrometers from the first edge and a distance from the first edge where 75% of the average retardance is observed of at least 10 micrometers. In some cases, a distance between the first and second side edges is up to 50 millimeters. In some cases, the article is a fastening tab. The method includes providing a thermoplastic film having opposing first and second side edges, with a distance between the opposing side edges of up to 50 millimeters, and stretching the thermoplastic film to form the thermoplastic layer, which is plastically deformed. The first surface of the thermoplastic film bears male fastening elements.Type: GrantFiled: December 19, 2016Date of Patent: April 6, 2021Assignee: 3M Innovative Properties CompanyInventors: Thomas J.

Patent number: 10223089Abstract: A method for partial redundancy elimination with a fixed number of temporaries includes determining local data values of program code that describe a temporary memory location, a set of registers, and a set of basic blocks. The method determines global data values of the program code based on the determined local data values of the program code. The method removes a first load of the temporary memory location in a first basic block in the program code. The method adds a second load on a first edge from a second basic block out of the set of basic blocks to a third basic block out of the set of basic blocks in the program code. The method performs a register move on a second edge from the third basic block to the second basic block in the program code.Type: GrantFiled: October 27, 2017Date of Patent: March 5, 2019Assignee: International Business Machines CorporationInventor: Steven J.

Patent number: 9782302Abstract: A wetness sensor includes a substrate that carries a tuned RF circuit. The circuit includes a conductive pattern applied to the substrate, a capacitor, and a jumper all disposed on a same side of the substrate. The conductive pattern includes an inductive coil, and an inner and outer terminus. The jumper electrically couples the inner terminus to the outer terminus. The jumper also includes a frangible link which, when contacted by a target fluid, produces a drastic change in the operation of the RF circuit. The drastic change can be interpreted by a remote reader as a “wet” condition. Contact of the frangible link by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or more, and/or may cause the frangible link to disintegrate to produce an open circuit, and/or may substantially render the RF circuit inoperative.Type: GrantFiled: February 4, 2015Date of Patent: October 10, 2017Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Justin M. Johnson, Lori-Ann S. Prioleau, Brinda B. Badri, James C. Vanous, Robert D. Lorentz, Jacob D. Chatterton, Steven J. Perron, Donald R. Battles

Publication number: 20170252227Abstract: A wetness sensor includes a self-supporting substrate and an electrically conductive trace carried by the substrate. The trace is patterned to provide at least a portion of a tuned RF circuit, which may be disposed on only one side of the substrate and characterized by an impedance or resistance. The trace is not self-supporting. The substrate is adapted to dissolve, swell, or otherwise degrade when contacted by a target fluid. Such degradation produces a drastic change in the operation of the RF circuit, which can be interpreted by a remote reader as a “wet” condition. Contact of the substrate by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or 1000, and/or may cause the trace to disintegrate so as to provide the RF circuit with an open circuit, and/or may substantially render the RF circuit inoperative.Type: ApplicationFiled: May 18, 2017Publication date: September 7, 2017Inventors: Lori-Ann S. Prioleau, Justin M. Johnson, Robert D. Lorentz, Brinda B. Badri, James C. Vanous, Jacob D. Chatterton, Steven J. Perron, Donald R. Battles, Badri Veeraraghavan
