Patent number: 7877009Abstract: A method and system of measuring the spectroscopic impedance of a sensor and its immediate surroundings. The sensor is disposed on an engineered structure and is coated with a protective coating. The method includes providing a first optical signal having a first modulation frequency and amplitude. The method also includes transmitting the first optical signal and a second optical signal from a first location to a sensor location. The method also includes modulating the second optical signal with a second modulation frequency and amplitude, the second modulation frequency and amplitude converted from the first optical signal. The method also includes comparing the first modulation frequency to the second modulation frequency to determine one of a phase difference and a time lag and calculating the electrochemical impedance spectroscopy of the sensor and its immediate surroundings as a function of frequency.Type: GrantFiled: December 20, 2007Date of Patent: January 25, 2011Assignee: 3M Innovative Properties CompanyInventors: Ding Wang, Steven Y.

Patent number: 7477060Abstract: A detection system for monitoring an engineered structure includes an array of sensors disposable in a predetermined pattern on the engineered structure and disposable between a surface of the engineered structure and a protective coating substantially covering the surface. The detection system also includes a data acquisition system in communication with the array of sensors for retrieving data from the sensors. The array of sensors can provide data corresponding to at least one of a degree of cure of the protective coating, a health of the cured protective coating, and a corrosion rate of the engineered structure at each of the sensors.Type: GrantFiled: December 27, 2005Date of Patent: January 13, 2009Assignee: 3M Innovative Properties CompanyInventors: Steven Y. Yu, Michael R. Matthews, Gary A. Shreve

Patent number: 6692895Abstract: A laser imageable article includes an imageable layer that comprises the reaction product of a metal precursor and a reactant. The imageable article also includes a first boundary layer on a first side of the imageable layer, the first boundary layer being substantially transparent to laser radiation, and a second boundary layer on a second side of the imageable layer. The imageable layer may be imaged with a laser through the first boundary layer while maintaining the continuity of the first boundary layer. In a preferred embodiment, the imageable layer comprises the reaction product of an ion of one or more metals selected from columns 8, 9, and 10 of the periodic table of elements and a reducing agent selected from hypophosphorus acid and salts thereof, sodium borohydride, and dimethylamine borane. One preferred embodiment of the imageable layer comprises from 1 to 30 mole percent phosphorus and up to 99 mole percent nickel.Type: GrantFiled: May 25, 2001Date of Patent: February 17, 2004Assignee: 3M Innovative Properties CompanyInventors: Haitao Huang, Michael N.

Patent number: 5973266Abstract: A method of altering a portion of the semiconductive layer of an electric power cable, to increase its resistance so as to render it electrically insulative. The semiconductive layer is loaded with carbon powder which forms chains to provide conductive pathways through the layer. By introducing an intercalant into the semiconductive layer, which causes the layer to swell, the conductive pathways are interrupted and the material is rendered insulative (>10.sup.4 .OMEGA.-cm). The intercalant may be a polymerizable material with a curing agent which is cured in situ, i.e., without removing the semiconductive layer from the cable. By this method, flashover to the semiconductive layer at a cable splice or termination may be prevented without requiring tedious removal of the exposed portion of the semiconductive layer. The method is usable with both strippable and coextruded semiconductive layers.Type: GrantFiled: March 24, 1998Date of Patent: October 26, 1999Assignee: 3M Innovative Properties CompanyInventors: Gary A. Shreve, Nanayakkara Liyanage Don Somasiri, Justine Anne Mooney, Alan George Hulme-Lowe, Curtis Roy Guilbert
