  • Patent number: 12351761
    Abstract: A catalytic process for the deoxygenation of an organic substrate, such as a biomass or bio-oil, is described. The catalytic process is conducted in the presence of a gaseous mixture containing both hydrogen and nitrogen. The presence of nitrogen in the gaseous mixture gives rise inter-aliato increased catalytic activity and/or increased selectivity for aromatic reaction products.

  • Patent number: 11701228
    Abstract: A system for treating valvular regurgitation in a heart valve includes a flexible canopy and an elongated tether including an elastic portion and an inelastic portion. When the system is in a deployed configuration, a proximal end of the flexible canopy is coupled to an annulus of the heart valve and a distal end of the elongated tether is coupled to a ventricle. The flexible canopy is configured to overlay a first native leaflet of the heart valve, and tension on the elongated tether is applied and/or adjusted to prevent the first leaflet from prolapsing, to maximize coaptation of the flexible canopy with a second native leaflet of the heart valve, and to minimize regurgitation of the heart valve.

  • Publication number: 20210157442
    Abstract: An interaction object can attach to a touch surface of a touch-sensitive device. The interaction object includes one or more contact portions that cause one or more touch events on the surface. The contact portions may have specific shapes or sizes or be arranged in a specific manner so that the touch-sensitive device can distinguish the interaction object from other touch objects that cause touch events (e.g., fingers or styli). Responsive to the touch-sensitive device recognizing an interaction object, a display may display a user interface associated with the identified interaction object. The user interface may allow a user to interact with the touch-sensitive device in ways that are intuitive and more efficient than conventional interaction techniques.
