Publication number: 20230345686Abstract: A method of embedding a screen in a substrate includes placing the screen on the substrate, and then melting part of the substrate, so that the screen becomes embedded in the substrate. The melting may involve heating at least part of the screen to melt part of the substrate, or directly heating the part of the substrate. The screen may be a screen of electrically-conductive material, and the heating may be Joule heating in which an electrical current is passed through the screen to heat the screen. Alternatively, the heating may involve microwave, conductive, or laser heating. The produced device of the substrate with an embedded screen may be an optical window with an embedded electromagnetic interference (EMI) screen, may be a touch screen or touch display, or may be a window with an embedded heating element, to give a few non-limiting examples.Type: ApplicationFiled: April 26, 2023Publication date: October 26, 2023Inventors: Catherine Trent, Raquel Ovalle-Robles, James E.

Patent number: 11524862Abstract: A dispenser is described for dispensing nanofiber yarns that includes a housing that defines an inlet, an outlet, and a chamber. A spool, around which is wound a length of nanofiber yarn, is disposed within the chamber defined by the housing. The nanofiber yarn is threaded from the chamber through the outlet and can be dispensed in a controlled way that reduces the likelihood of developing knots within the nanofiber yarn, and which facilitates convenient application of the yarn onto an underlying surface. In some cases, the dispenser can be used to concurrently dispense an adhesive or other polymer along with the nanofiber yarn.Type: GrantFiled: October 30, 2020Date of Patent: December 13, 2022Assignee: LINTEC OF AMERICA, INC.Inventors: Márcio D. Lima, Raquel Ovalle-Robles

Patent number: 11479438Abstract: A nanofiber structure applicator is described that can remove two substrates from opposing major surfaces of a nanofiber structure. The two substrates can have differing adhesive strengths with the nanofiber forest. This difference in adhesive strength can be used to reorient nanofibers that form the nanofiber structure relative to the final surface on which they are applied. This reorienting of the individual nanofibers within a nanofiber structure can be used to tailor some of the properties of the nanofiber structure. Furthermore, the nanofiber structure applicator is configured can improve the convenience with which a nanofiber structure can be transported and applied to an application surface.Type: GrantFiled: April 15, 2020Date of Patent: October 25, 2022Assignee: LINTEC OF AMERICA, INC.Inventors: Jordan Benson, Raquel Ovalle-Robles, Nicklas Keller

Publication number: 20210164452Abstract: Polymer and nanotube-based actuators that include a thermochromic coating is disclosed. The actuators include a thermochromic material applied to a surface of the core fiber or the conductive element. Upon heating the actuator, the thermochromic coating undergoes a color transition to indicate a pre-determined temperature correlated to a rated critical temperature, important temperature of the actuator components, or a level of actuation.Type: ApplicationFiled: May 10, 2019Publication date: June 3, 2021Applicant: LINTEC OF AMERICA, INC.Inventors: Jaeah LEE, Marcio Dias LIMA, Sergey LI, Raquel OVALLE-ROBLES

Publication number: 20200203046Abstract: Holders for nanofiber sheets that can reduce the probability of damage to a nanofiber sheet during transport, handling, or experimental preparation are described. These holders can improve the convenience with which nanofiber sheets can be manipulated. Holders generally include two features: an outer case and a clamp disposed within the outer case. The clamp, which can be embodied in any of a variety of ways, mounts to a peripheral edge at one or more locations on the nanofiber sheet. The nanofiber sheet is held fixed in place within the outer case and is suspended within the chamber defined by the outer case and the client.Type: ApplicationFiled: February 28, 2020Publication date: June 25, 2020Applicant: Lintec of America, Inc.Inventors: Chi Huynh, Jaeah Lee, Raquel Ovalle-Robles

Patent number: 10562775Abstract: The present invention provides a method for producing a carbon nanotube sheet that is excellent in light transmittance and conductivity, and the carbon nanotube sheet. The method includes firstly modifying of modifying a free-standing unmodified carbon nanotube sheet in which a plurality of carbon nanotubes are aligned in a predetermined direction. The firstly modifying includes performing a densification process of bringing the unmodified carbon nanotube sheet into contact with either one of or both of vapor and liquid particles of a liquid substance to produce a modified carbon nanotube sheet that contains the carbon nanotubes which are mainly aligned in a predetermined direction, and that includes a high density portion where the carbon nanotubes are assembled together and a low density portion where density of the carbon nanotubes is relatively lower than density in the high density portion.Type: GrantFiled: November 20, 2015Date of Patent: February 18, 2020Assignees: Lintec Corporation, Lintec of America, Inc., Kinki UniversityInventors: Raquel Ovalle, Senku Tanaka, Kanzan Inoue
