Abstract:
Natural-scene light is polarized so the light exiting the polarizer and entering a glass assembly has a first polarization. Light having a second polarization substantially orthogonal to the first polarization is launched into the glass assembly and directed normal to the glass assembly and into a zone plate assembly, along with the natural-scene light. A first plurality of electric fields is established in the zone assembly to form at least one zone plate that modulates the launched light without modulating the natural-scene light. The first plurality of electric fields is disestablished and a second plurality of electric fields is established in the zone plate assembly to reposition the at least one zone plate in the liquid crystal plate. Disestablishment and establishment of electric fields is repeated at a sufficient rate so that an image defined by a number of pixel spots formed on a retina is perceived by a viewer.
Abstract:
Various aspects directed towards automating an onboarding procedure are disclosed. In a first aspect, an administrative communication associated with onboarding an onboardable device is received by an access point (AP) device, such that the administrative communication originates from a device different than the onboardable device. The AP device then enables the onboardable device to access a secure network based on the administrative communication. In another aspect, an identifier is transmitted from an onboardable device while the onboardable device operates in an AP mode. The onboardable device then receives credentials associated with accessing a secure network via an AP device. Here, the credentials received from the AP device are in response to an authentication of the identifier by an administrator. The onboardable device then connects to the secure network by utilizing the credentials.
