Publication number: 20210229834Abstract: The systems and techniques of this disclosure relate to improving work safety in confined spaces by, for example, using machine vision to analyze location marking labels in the confined space to control an unmanned aerial vehicle (UAV) within the confined space. In one example, a system includes a UAV that includes an imaging device and a processor communicatively coupled to the imaging device. The processor may be configured to receive, from the imaging device, an image of a confined space, detect a location marking label within the image, process the image to decode data embedded on the location marking label, and control navigation of the UAV within the confined space based on the data decoded from the location marking label.Type: ApplicationFiled: May 8, 2019Publication date: July 29, 2021Inventors: James W.

Patent number: 10405796Abstract: Methods for estimating and predicting tooth wear based upon a single 3D digital model of teeth. The 3D digital model is segmented to identify individual teeth within the model. A digital model of a tooth is selected from the segmented model, and its original shape is predicted. The digital model is compared with the predicted original shape to estimate wear areas. A mapping function based upon values relating to tooth wear can also be applied to the selected digital model to predict wear of the tooth.Type: GrantFiled: July 20, 2017Date of Patent: September 10, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Evan 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
