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

Patent number: 5172905Abstract: A receive magazine for collecting and transporting sheets of exposed photographic media. The receive magazine includes an elongated, light-tight enclosure having front and back walls, top and bottom walls, and first and second end walls. Sheets of media are gravity fed into the magazine entrance through a collection door on the top wall of the enclosure. The collection door includes a media-receiving slot, a shutter and a spring for biasing the shutter to a normally closed, light-tight position over the slot. A lower downwardly sloping resilient member mounted to the front wall engages the sheets as they are inserted into the magazine and forces the sheets into a vertically stacked arrangement against the back wall of the enclosure, away from the entrance. A ramp surface on the back wall guides sheets being inserted over previously collected sheets. A compound curved surface on the back wall of the enclosure below the ramp surface arcs the sheets to minimize contact during insertion.Type: GrantFiled: June 19, 1991Date of Patent: December 22, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: James C. Vanous, Robert L. Rydeen, Thomas J. Lundgren, Bert A. Munthe, Arnold B. Dammermann
