  • Publication number: 20240083189
    Abstract: A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

  • Publication number: 20240060584
    Abstract: A connection portion for a surgical instrument provides an improved means of connection between a surgical instrument and a hose. The hose may supply irrigation fluid or may be connected to a suction source. The connection portion includes a part which is connected to and movable with the hose, ensuring that the connection between the connection portion and the hose does not limit the flow of fluid through the hose even as the hose moves. This further reduces the apparent feeling of weight caused by the hose on the surgical instrument.

  • Publication number: 20240059094
    Abstract: An optical product can reproduce a first 3D image of at least part of a first 3D object and a second 3D image of at least part of a second 3D object. The optical product comprises a surface configured, when illuminated, to reproduce by reflected or transmitted light, the first 3D image without reproducing the second 3D image at a first angle of view, and the second 3D image without reproducing the first 3D image at a second angle of view. Each portion of first portions can correspond to a point on a surface of the first 3D object, and comprise first non-holographic features configured to produce at least part of the first 3D image. Each portion of second portions can correspond to a point on a surface of the second 3D object, and comprise second non-holographic features configured to produce at least part of the second 3D image.

  • Patent number: 11861966
    Abstract: An optical device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. In some examples, individual ones of the first and second segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the first and second segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

  • Publication number: 20230264510
    Abstract: An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. The images can produce one or more optical effects.

  • Publication number: 20220276502
    Abstract: An optical product can be configured, when illuminated, to reproduce an image that appears to be a 3D image of at least a part of a 3D object. The optical product can include a surface comprising a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. One or more non-holographic features can be disposed within each portion configured to produce at least part of the image without relying on diffraction. An interference optical structure can be disposed on one or more features. A gradient in the features can correlate to a surface normal of the surface of the 3D object at the corresponding point. An orientation of the features can correlate to an orientation of the surface of the 3D object at the corresponding point.
