Patent number: 11802502Abstract: An exhaust system includes a light-off catalyst, an exhaust system component, and at least one H2O trap. The exhaust system component is upstream from the light-off catalyst and includes catalyst material, the catalyst material configured to store hydrocarbons during a period when the light-off catalyst is warming up to a light-off temperature. The at least one H2O trap is at or upstream from the exhaust system component and is configured to perform H2O adsorption and desorption to increase a length of time for the exhaust system component to reach a hydrocarbon release temperature and prevent the exhaust system component from reaching the hydrocarbon release temperature prior to the light-off catalyst reaching the light-off temperature.Type: GrantFiled: January 30, 2023Date of Patent: October 31, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Patrick G. Szymkowicz, Mingjie Tu, Yuntao Gu, Calvin Thomas

Patent number: 9250386Abstract: Disclosed is an optical fiber having a core with an alkali metal oxide dopant in an peak amount greater than about 0.002 wt. % and less than about 0.1 wt. %. The alkali metal oxide concentration varies with a radius of the optical fiber. By appropriately selecting the concentration of alkali metal oxide dopant in the core and the cladding, a low loss optical fiber may be obtained. Also disclosed are several methods of making the optical fiber including the steps of forming an alkali metal oxide-doped rod, and adding additional glass to form a draw perform. Preferably, the draw preform has a final outer dimension (d2), wherein an outer dimension (d1) of the rod is less than or equal to 0.06 times the final outer dimension (d2). In a preferred embodiment, the alkali metal oxide-doped rod is inserted into the centerline hole of a preform to form an assembly.Type: GrantFiled: June 25, 2014Date of Patent: February 2, 2016Assignee: Corning IncorporatedInventors: James Gary Anderson, Dana Craig Bookbinder, Lisa Carine Chacon, Calvin Thomas Coffey, Adam James Ellison, Gregory Gerard Gausman, Rostislav Radiyevich Khrapko, Stephan Lvovich Logunov, Michael Thomas Murtagh, Clinton Damon Osterhout, Sabyasachi Sen, William Anthony Whedon

Patent number: 9138177Abstract: Methods and apparatus for the recovery, visualization and enhancement of latent fingerprints using Low Pressure Dye Vapor Deposition (LPDVD) are described. The LPDVD methods of the present invention provide for fine control over the deposition of a precursor in combination with a fluorescent dye, combination of dyes or a premixed dry solid compound of the precursor and dyestuffs, to make the latent fingerprints visible. The LPDVD process makes use of a heated carrier gas to dilute and carry the vapors into a vacuum chamber where they condense onto the exposed surfaces of the article being developed. The LPDVD process can be used to develop latent fingerprints on a wide variety of substrates, including metal, plastic, glass and thermal paper and has been shown to perform as well or better than conventional fingerprint development techniques on these surfaces.Type: GrantFiled: July 24, 2013Date of Patent: September 22, 2015Assignee: Linde AktiengesellschaftInventor: Calvin Thomas Knaggs
