  • Patent number: 11969542
    Abstract: In some examples, provided is a fluid blockage device for use with a reduced-pressure source for treating a tissue site with reduced pressure. The fluid blockage device may be configured to preclude fluid communication through a port fluidly coupled to the reduced-pressure source when the fluid blockage device contacts a liquid. Other devices, systems, and methods are disclosed.

  • Patent number: 11969317
    Abstract: A wound dressing includes an inelastic absorbent layer, an elastic film, and a plurality of welds. The inelastic absorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The elastic film is configured to elastically stretch when a stretching force is applied to the wound dressing and elastically recover when the stretching force is removed. The plurality of welds fix the elastic film to the first side of the inelastic absorbent layer such that the elastic film and the inelastic absorbent layer elastically stretch and elastically recover as a unit.

  • Publication number: 20220330488
    Abstract: The present application is directed to a system and processing method for fractionating pre-formed forage hay bales into a fractionated leaf portion and a fractionated stem portion. More particularly, the system involves grinding, chopping and shredding bales, and fractionating the chopped and shredded bales using a shaker table and grate assembly, into a fractionated leaf portion and a fractionated stem portion using a shaker table. The resulting fractionated leaf portion and fractionated stem portion can then be further processed into pellets for animal feed products, or the fractionated stem portion can be re-baled. Pelletization includes customizing the size of the pellets and the addition of additives to the pellets according to customers specifications for customized animal feed products. Pellets derived from the fractionated leaf portion and the fractionated stem portion are then packaged, typically in bags, for storage and transport.

  • Publication number: 20220295742
    Abstract: A water filtering pet bowl assembly includes a bowl including a raised drinking water location, a bottom to-be-pumped water location having a raised platform, and a central channel between the raised drinking water location and the bottom to-be-pumped water location, such that, in an in-use operation of the water filtering pet bowl assembly, water flows by gravity flow from the raised drinking water location, through the central channel, and to the bottom to-be-pumped water location; a filter assembly positioned above the bottom to-be-pumped water location; and a pump coupled with the filter assembly and positioned in the bottom to-be-pumped water location; wherein, in the in-use operation of the water filtering pet bowl assembly, a base of the filter assembly is positioned on the raised platform.

  • Publication number: 20220101486
    Abstract: Computer-implemented system and method that allows for the rehabilitation of individuals with strabismus by leveraging commercially available VR headset technology. Eye tracking capabilities and external cameras of existing VR headsets, enables the system and method to first gather the image that the dominant, unaffected eye is focused on (FIG. 1). Then, given where the strabismus unaffected eye's gaze falls on its screen, the system and method will take the image and identify where that point lies on the strabismus affected eye's screen. This point is the ideal gaze point of the strabismus affected eye. The software solution disclosed herein will then warp the strabismus affected eye's screen so that this new gaze will line up with the unaffected eye's gaze.

  • Patent number: 11026369
    Abstract: The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method will accomplish seven steps in one pass of the combine harvester. This apparatus and processing method harvests leaf crops and is configured to perform multiple processing operations, including fractionation of the leaf crop, leaf maceration, leaf sizing, elevating the leaf fraction to a transport vehicle, and stem conditioning, cutting and windrowing, in a single pass through the crop field. These steps are accomplished using a header unit, an adapter feeder macerator and a forage harvester vehicle, expeditiously removing the leaf fraction from the field. Following leaf fraction harvesting, the leaf fraction is processed by densification into forage feed products. The processed leaf fraction can be combined with other feeds to make up customized feed rations. The stem fraction is also processed. The present invention can also be used to harvest grass crops.
