  • Patent number: 12329290
    Abstract: A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

  • Patent number: 12005725
    Abstract: The present invention relates to a method of forming a surface covering for example wallpaper or a floor covering and an apparatus for forming a surface covering, in which a surface covering raw material is supplied, the surface covering raw material comprising a substrate and a resin layer comprising a resin and a carrier liquid, the resin being dispersed in the carrier liquid and being capable of gelling or curing with the carrier liquid. A pattern is then applied to the resin layer by inkjet printing, and the surface covering raw material with the pattern formed on the resin layer is heated to gel or cure the resin layer to thereby prepare a surface covering.

  • Patent number: 11722626
    Abstract: A system determines an object-design for a three-dimensional model of an object. The object-design may exhibit a design continuity. The system breaks the object-design in to spatial patterns corresponding to the discrete surfaces making up the outward surface of the object. The system then generates flattened patterns by projecting the spatial patterns into a two-dimensional plane. The system prints the flattened patterns on to designated regions of material sheets in an orientation that preserves the design continuity of the object-design. The regions may be extracted from the sheets and then joined at their edges to form a cover for object that exhibits the continuity of the object design.

  • Publication number: 20220381055
    Abstract: An assistive device for a door having a door lock mounted adjacent to a doorknob. The door lock is rotationally actuatable via a thumb lever. The assistive device comprises a handle adapted to mount on to the thumb lever without obstructing the doorknob and a mounting slot formed between opposed ends of the handle for forming a frictional fit between the handle and the thumb lever. The handle includes an elongated end configured to provide leverage for rotation of the thumb lever using the handle, and an arcuate end for grasping. The mounting slot at least partially surrounds the thumb lever in a plane of rotation thereof.

  • Patent number: 11110731
    Abstract: Provided is a method for applying an ink for applying an oil-based ink to a resin composition layer of a target including a base and the resin composition layer formed over a surface of the base, the method including: a pretreatment step of pre-treating the target before the oil-based ink is applied, with at least one surface treatment for improving a wetting/spreading property of the oil-based ink; a step of applying the oil-based ink to the target that has undergone the pretreatment step; and a post-treatment step of post-treating the target after the oil-based ink is applied, with at least one surface treatment for improving a wetting/spreading property of the oil-based ink.
