  • Patent number: 11960149
    Abstract: Provided is technology that makes it possible to measure visual behavior with respect to objects that are at different distances in the depth direction, while reducing burden on a subject. A method for measuring visual behavior of a subject to design an eyeglass lens includes: a step (a) of ascertaining a head rotation amount that is generated by the subject in a sagittal plane of the subject when gazing at each of a plurality of gaze points that are set at predetermined distances different from each other in a forward depth direction; and a step (b) of determining an eyeball rotation amount that is generated by the subject when gazing at each of the plurality of gaze points, based on the head rotation amount.

  • Patent number: 11447624
    Abstract: The present disclosure relates to TPV compositions suitable for foaming, as well as foamed TPV compositions, methods of making the foregoing, and applications of various foamed TPV compositions, including in glass run channels. The TPV compositions comprise an at least partially vulcanized rubber component dispersed within a thermoplastic component comprising a first thermoplastic resin. According to some aspects, the TPV composition may be combined with a high melt-strength thermoplastic resin, and in particular a high melt-strength polypropylene-based thermoplastic resin, to make a foamable TPV composition. The foamable TPV composition (with or without high melt-strength thermoplastic resin) is then coextruded or otherwise combined with foaming agent (preferably comprising thermo-expandable microspheres) to form the foamed composition.
