Patent number: 11680202Abstract: An article that includes a fluorescent composition having at least one of a fluorescent sensor compound and organic reporter molecules encapsulated in a microsphere structure. When encapsulated, the fluorescent sensor compound and the organic reporter molecules are distributed in a liquid organic matrix. When non-encapsulated, the remaining one of the fluorescent sensor compound and the organic reporter molecules reside in the matrix. In response to a force applied to the composition sufficient to break at least a portion of the microsphere structure, the fluorescent sensor compound and the organic reporter molecules are transformed into a non-reversible fluorescent state exhibiting a quantum yield greater than 0.2. The fluorescent state is objectively visually verifiable without physically contacting the composition.Type: GrantFiled: July 21, 2021Date of Patent: June 20, 2023Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Heidi A. Smartt, Dianna S. Blair, Juan A. Romero, Patrick L. Feng

Patent number: 8186731Abstract: Seals have a flexible wire that can be looped through a hasp-like device. The seals include a body having a recess, a plug insertable into the recess and a snap ring for fastening the plug to the body. The plug and/or body can have access holes for inserting the wire into the recess. “Teeth” on the outer diameter and through-holes through the thickness of the snap ring allow for passing the ends of the flexible wire from the recess through the snap ring. The ends of the wire can be folded back over the snap ring and into engagement with the teeth. Assembly of the seal causes the ends of the wire to be securely fastened between the teeth of the snap ring and the sidewall of the recess. Seals can include a plug and/or body made of a frangible material such as glass, ceramic, glass-ceramic or brittle polymer.Type: GrantFiled: April 14, 2009Date of Patent: May 29, 2012Assignee: Sandia CorporationInventors: Juan A. Romero, Charles A. Walker, Dianna S. Blair, Connie C. Bodmer

Patent number: 6076406Abstract: By measuring two or more physical parameters of a thin sensing film which are altered when exposed to chemicals, more effective discrimination between chemicals can be achieved. In using more than one sensor, the sensors are preferably integrated on the same substrate so that they may measure the same thin film. Even more preferably, the sensors are provided orthogonal to one another so that they may measure the same portion of the thin film. These provisions reduce problems in discrimination arising from variations in thin films.Type: GrantFiled: March 25, 1998Date of Patent: June 20, 2000Assignee: Sandia CorporationInventors: Dianna S. Blair, Gregory C. Frye-Mason, Michael A. Butler

Patent number: 5922106Abstract: An apparatus and process for the continuous, near real-time monitoring of low-level concentrations of organic compounds in a liquid, and, more particularly, a water stream. A small liquid volume of flow from a liquid process stream containing organic compounds is diverted by an automated process to a heated vaporization capillary where the liquid volume is vaporized to a gas that flows to an automated gas chromatograph separation column to chromatographically separate the organic compounds. Organic compounds are detected and the information transmitted to a control system for use in process control. Concentrations of organic compounds less than one part per million are detected in less than one minute.Type: GrantFiled: April 20, 1998Date of Patent: July 13, 1999Assignee: Sandia CorporationInventors: Curtis D. Mowry, Dianna S. Blair, Philip J. Rodacy, Stephen D. Reber

Patent number: 5187980Abstract: A method and apparatus for sensing a liquid-solid phase transition event is provided which comprises an acoustic plate mode detecting element placed in contact with a liquid or solid material which generates a high-frequency acoustic wave that is attenuated to an extent based on the physical state of the material is contact with the detecting element. The attenuation caused by the material in contact with the acoustic plate mode detecting element is used to determine the physical state of the material being detected. The method and device are particularly suited for detecting conditions such as the icing and deicing of wings of an aircraft. In another aspect of the present invention, a method is provided wherein the adhesion of a solid material to the detecting element can be measured using the apparatus of the invention.Type: GrantFiled: May 31, 1990Date of Patent: February 23, 1993Assignee: The United States of America as represented by the United States Department of EnergyInventors: Dianna S.
