  • Patent number: 11351313
    Abstract: A system and method for monitoring the pressure of an injection site, utilizing a fluid operating in the laminar regime flowing through a calibrated tube, and measuring a pressure at one end of the calibrated tube with a pressure sensor, as well as a fluid velocity with a flow sensor, such as an elastic filament velocimeter, that comprises a nano-scale sensing element. Additional elements may be utilized, including the use of data acquisition units, processors, user interfaces, pumps, syringes, and control loops.
    Type: Grant
    Filed: February 22, 2018
    Date of Patent: June 7, 2022

  • Patent number: 11054290
    Abstract: Disclosed is an apparatus for measuring velocity of a fluid stream via deflection of a wire filament. Also disclosed is a process for measuring velocity of a fluid stream, requiring deflecting two or more wire filaments in a fluid stream, measuring two or more resistances, and equating the velocity of the fluid stream to the result of a function of the two or more resistances. In both the apparatus and method, one wire filament must have a length dimension longer than at least one of a dimension of the wire filament in the primary sensing or transverse direction, as well as a dimension of the wire filament in the primary sensing and/or transverse direction less than 50 ? ? ? U ? ? ? throughout a predetermined operating range.

  • Publication number: 20160122677
    Abstract: In a broad aspect of the invention there are provided liquid infused surfaces that feature drag reducing characteristics. In a further broad aspect, the present invention provides methods for designing and fabricating liquid infused surfaces that feature drag reducing characteristics. In a yet further broad aspect the present invention provides methods for increasing the operating efficiency of systems in which a flowing bulk fluid is in contact with a patterned surface, the increased operating efficiency specifically being realized from a reduction of the drag forces due to the bulk fluid flowing over the patterned surface.
