  • Patent number: 11808290
    Abstract: A fluid flow conditioning apparatus having self-adjusting tab members that reduce flow losses within a conduit. A plurality of tabular members is affixed to an insertion plate-type flow conditioner. Tabular members are cojoined in pairs at their leading edges. When the cojoined pair of the first tabular member and the second tabular member are placed into a fluid flow, an angle between the first tabular member and the second tabular member is configured to decrease in response to static and dynamic pressure exerted onto the outer surfaces of the tabular members by the fluid flow. The tabular members may be made of a hyperplastic material configured to undergo an elastic deformation and exhibit flapping due to the dynamic pressure of the fluid flow. Tabular members maybe cojoined by a hinge configured to partially close in response to pressure exerted by the fluid flow, decreasing the angle between the tabular members.

  • Publication number: 20230174208
    Abstract: A Flettner rotor that employs localized suction over its surface improves performance and fuel efficiency. Simulations and analysis show that such a method can significantly improve the performance of the Flettner rotor. Improvements in rotor performance enable reduction in fuel costs and greenhouse gas emission by ships or other modes of transport. Improvements in rotor performance can also reduce noise for applications such as drones or other devices having rotors.

  • Patent number: 10853763
    Abstract: Techniques for onboarding new service providers based on portable service provider attributes are described. In an example, a server computing device may determine service provider attribute(s) of a service provider associated with a first merchant and associate the service provider attribute(s) with a data entry corresponding to an identifier of the service provider in a database. The server computing device may subsequently receive, from a point-of-sale device operated by a second merchant, identification data associated with the service provider and may determine the identifier of the service provider based on the identification data. Based on the identifier, the server computing device may access the service provider attribute(s) associated with the service provider from the database and may update a second merchant service inventory associated with the second merchant based on the service provider attribute(s) of the service provider.

  • Patent number: 10485517
    Abstract: The present invention provides a method for determining thromboembolic risk in a patient. The method includes processing functional images of a patient's heart in order to create a computational fluid dynamic (CFD) modeling of the patient's heart. Once a CFD model is obtained, various metrics can be determined to estimate the patient's risk of left ventricular thrombosis. This method is particularly suited for determining thromboembolic risk in patients having suffered a myocardial infarction. However, the method can also be applied to a broader population at risk of cardioembolic and cryptogenic stroke.
