Publication number: 20230383139Abstract: A method for creating a dielectric thin-film coating for devices having a fusible element is disclosed. The method comprises mixing insoluble and soluble polymers in solid form and exposing the mixture to heat to create a melt mixture. The melt mixture is then dissolved in a solvent to create a slurry which can then be deposited on the device as a thin-film coating to create an interior insulation layer or an external surface.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Applicant: Littelfuse, Inc.Inventors: YURIY BORISOVICH MATUS, MARTIN G.

Publication number: 20230358625Abstract: Gravity-actuated display systems suitable for use as security markers, for example to incorporate into bank notes. The devices can be made very thin and flexible, yet are robust enough to endure the harsh conditions of paper currency in general circulation. Because the displays are gravity actuated, they do not require a power source or circuitry. The gravity-actuated displays can be fabricated using microembossing or photolithography and can be filled and sealed using roll-to-roll techniques. The microcells can also be patterned to provide custom designs, such as official seals.Type: ApplicationFiled: May 1, 2023Publication date: November 9, 2023Inventors: Yuriy Borisovich MATUS, Chandra Bikram KC, Haiyan GU, Ajeet KUMAR, Bryan Hans CHAN
