  • Publication number: 20260184939
    Abstract: An anti-fouling shield composite material for shielding and removing ice or slush from a surface and a method of forming the same. The composite material including a cured organogel matrix and an auxetic skeletal structure, wherein the composite material has a negative Poisson's ratio that results in an increase in net surface area of the shield to shed ice from a surface of the shield when stretched. The method including mixing a silicone and a silicone oil to form an uncured organogel matrix; separately mixing fumed silica and a silicone precursor to form a second uncured material; curing the second uncured material to form the cured auxetic skeletal structure and molding that into a shape of the anti-fouling shield; pouring the uncured organogel matrix around and covering the cured auxetic skeletal structure; and curing the uncured organogel matrix to form the anti-fouling shield composite material.

  • Patent number: 11841027
    Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.
