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: 11241752Abstract: Nanometers thick conformal coatings deposited by atomic-layer deposition (ALD) onto the metal surface of an active braze joint modifies the surface chemistry to eliminate excess braze filler metal flow. Unlike other means used to prevent braze filler metal runout, the thin ALD coating does not hinder next assembly processes, does not require post-braze cleaning, and does not alter the base material mechanical properties.Type: GrantFiled: May 10, 2019Date of Patent: February 8, 2022Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Ronald S.

Patent number: 10572786Abstract: A reflective particle tag reader system includes a read head assembly having a camera, illuminators, and a rigid frame portion for supporting the camera and the illuminators. The illuminators illuminate a focal point located opposite the camera where a reflective particle tag is placed. A computer in data communication with the camera receives and store images of the reflective particle tag that are acquired by the camera. The computer is programmed to process video images and to quantify a positional alignment parameter and an angular alignment parameter of the reader with respect to the reflective particle tag. A rapid burst of image frames is obtained in response to the positional alignment and the angular alignment parameters being within a predetermined tolerance and identity of the reflective tag is established between a first image set and a second image set.Type: GrantFiled: September 25, 2018Date of Patent: February 25, 2020Assignees: National Technology & Engineering Solutions of Sandia, LLCInventors: Heidi A. Smartt, William C. Sweatt, Michael B. Sinclair, Michael McDaniel, Juan A. Romero, Keith Tolk

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.
