A display medium displays a predetermined number of contents corresponding to a predetermined number of azimuth angles when viewed from a predetermined elevation angle and azimuth angle. An example display medium includes: a planar member that reflects light; and a plurality of protruding members, each protruding member of the plurality of protruding members has a surface occluding the light, placed vertically on the planar member and parallel to each of the predetermined number of azimuth angles. The planar member is partitioned into a plurality of unit cells, where each unit cell is further partitioned into the predetermined number of sub-cells corresponding to the predetermined number of azimuth angles. The protruding member that has the surface parallel to the predetermined azimuth angle is formed for each sub-cell corresponding to the predetermined azimuth angle.

An optical device comprises a support having a reference plane, and a dielectric periodic structure including a plurality of periodic elements which are arranged, on the reference plane, in a two-dimensional lattice having a sub-wavelength spacing and are either projections projecting from the reference plane or recesses depressed from the reference plane. The optical device further includes a metal layer, which is positioned on a surface of the periodic structure including a region of the reference plane surrounding the individual periodic elements and the surfaces of the periodic elements and which has a shape that follows the surface profile of the periodic structure.

A system and method for displaying advertisements on utility poles is provided. In one aspect, the system allows users to generate revenue by placing advertisements on utility poles. The system generally comprises a display, display mount, processor operably connected to the display, power supply, and non-transitory computer-readable medium coupled to the processor and having instructions stored thereon. The user interface allows users to choose content that may be presented via the displays. Chosen content is transferred to the displays by the processor over a network. The displays may be grouped in ways that allow users to control multiple displays at once. Various permission levels may be used to limit which displays users have access too, allowing various degrees of control for each display of the system.

The present invention relates to a solar power generation assembly and method for providing same involving an array of solar generating modules on a dual-incline structure, which can achieve high energy yields over a wide range of azimuths/orientations. The assembly consists of canopy wings providing for the dual-incline structure, where, depending on specifications, the canopy wings can differ in length, width, angle of inclination, structural material and solar module or other material mounted on the surface. The canopy wings may be pivoted or hinged to enhance the energy generation and/or other functional benefits of the assembly or system, including display elements, advertising, rainwater/precipitation and snow drainage and collection and energy transmission. The assembly or system is modular and may be assembled in a long continuous configuration in which the inclination, width and tilt of the canopy wings may vary of a long distance to maintain substantially consistent energy yields as the assembly or system orientation changes.

An optical device that produces flicker-like optical effects is provided. The optical device employs directionally cured image icons. Specifically, the optical device is made up of at least one arrangement of image icons formed from one or more cured pigmented materials, and at least one arrangement of optionally embedded focusing elements positioned to form one or more synthetic images of at least a portion of the arrangement(s) of image icons. Some or all of the pigmented material(s) is cured using collimated light directed through the focusing elements toward the arrangement(s) of image icons at one or more angles relative to a surface of the optical device to form directionally cured image icons. The synthetic image(s) of the directionally cured image icons is viewable at the cure angle(s) and therefore visually appears and disappears, or turns on and off, as the viewing angle of the device moves through the cure angle(s).

An information display device includes a light emitting panel, a shutter panel, and a controller. The light emitting panel includes a plurality of transmitting portions configured to transmit first light and a plurality of light emitting portions configured to emit second light. The transmitting portions and the light emitting portions are configured to be alternately arranged along a predetermined direction including a component in a direction in which a first eye and a second eye of a user are arranged. The shutter panel is configured to be positioned to be overlapped with the light emitting panel and includes a dimming region which is capable of operating so that the first light and the second light are reduced. The controller is capable of controlling the dimming region so that the first light enters the first eye and the second light enters the second eye.
