  • Publication number: 20220221735
    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: 20210271105
    Abstract: In certain embodiments, a master for fabricating an optical product is disclosed. For example, the optical product can be configured to be an anti-counterfeit feature such as a patch, a window, or a thread on a banknote. The optical product can be configured, when illuminated, to reproduce by reflected or refracted light, a 3D image of at least a part of a 3D object. The master can include a first surface and a second surface opposite the first surface. The second surface can include a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. Each portion can include features corresponding to non-holographic elements on the optical product. A gradient in the features can correlate to an inclination 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.

  • Patent number: 9942106
    Abstract: A network broker divides IP address space into subnets to allow IT infrastructure transfers using a cloud computing environment. A link established between a client and network broker allows transfer of data and provides connectivity between the client and cloud providers. IT infrastructure to be divested is provisioned onto subnets in a cloud environment. A second link is established via the network broker between the entity being divested and the provisioned IT infrastructure. Client access to provisioned IT infrastructure is cut by rerouting, at the network broker, traffic destined to the subnet(s) hosting the provisioned IT infrastructure from the link to the second link. After a new owner assimilates the divested IT infrastructure using the second link, network broker routing rules are adjusted to sever access of the new owner to the subnet(s) hosting the divested IT infrastructure and return access to the subnet(s) to the client.
