  • Patent number: 11669009
    Abstract: A method for fabricating patterns on a flexible substrate in a roll-to-roll configuration. Drops of a monomer diluted in a solvent are dispensed on a substrate, where the drops spontaneously spread and merge with one another to form a liquid resist formulation. The solvent is evaporated (e.g., blanket evaporation) from the liquid resist formulation followed by selective multi-component resist film evaporation resulting in a non-uniform and substantially continuous film on the substrate. The gap between the film on the substrate and a template is closed such that the film fills the features of the template. After cross-linking the film to polymerize the film, the template is separated from the substrate thereby leaving the polymerized film on the substrate.
    Type: Grant
    Filed: August 3, 2017
    Date of Patent: June 6, 2023

  • Publication number: 20140321235
    Abstract: Techniques for navigating a high temperature low visibility environment are supported. A system may employ appropriate sonar signals to determine and display the location or distance to remote structures that may be obscured in the high temperature low visibility environment. Firefighters, military personnel, and other individuals that must navigate through obscured, high temperature environments may interact with suitable devices, such as a handheld device, to access and display the approximate location or distance of the remote structures or pathways. These devices may facilitate effective navigation of high temperature low visibility environments, thereby minimizing the risk of traumatic or fatal bodily injuries posed by the dangerous conditions.
