Publication number: 20220187265Abstract: A sensor system that removes responses from an interferent and/or corrects for baseline drift of a sensor to determine a presence, a concentration or a change in concentration of a target material in a gaseous environment. Fluid flowing into the system may be directed by a valve arrangement to either a first fluid flow path or a second fluid flow path. The target material may be absorbed by a filter material in the first fluid flow path. Fluid flowing along the second gas flow path passes directly to the sensor. Responses of the sensor to fluids from the first and second fluid flow paths may be used to determine a presence, concentration or change in concentration of the target material.Type: ApplicationFiled: March 16, 2020Publication date: June 16, 2022Applicant: Sumitomo Chemical Co., Ltd.Inventors: Daniel Tobjork, Nicholas Dartnell, Pascal Cachelin, Robert Archer

Patent number: 10551744Abstract: Systems, devices, and methods for printing on surfaces of three-dimensional objects are provided. The systems, devices, and methods allow for images, and three-dimensional structures, to be printed onto a surface of a three-dimensional object. The surface of the three-dimensional object can have many different shapes, including an arbitrary or non-uniform shape having multiple curves. In one exemplary embodiment, the method includes associating a pattern of polygons with a surface of a three-dimensional object and then scaling a pattern of polygons associated with an image to be printed onto the surface with the pattern of polygons associated with the surface. One or more polygons of the scaled pattern of polygons are then progressively projected onto the surface, and a photosensitive material associated with the surface is cured to set projected image portion on the surface. Systems, devices, and other methods for printing onto surfaces of three-dimensional objects are also provided.Type: GrantFiled: May 28, 2019Date of Patent: February 4, 2020Assignees: Massachusetts Institute of Technology, The Regents of the University of MichiganInventors: Anastasios John Hart, Christopher Ryan Oliver, Adam Gregory Stevens, Jieyuan Wu, Chad Robert Archer
