Abstract: A STEM educational building set (i.e., apparatus) consists of a double-side multiplane imaging display device that provides two simultaneous and distinct 2D/3D scenes. Viewers with polarized goggles can observe 3D multiplane scenes (i.e., a 3D scene for each axial plane) by displaying two laterally separated images of the same scene with different polarization. The building set teaches users optics, exposing them to refraction law, lateral magnification, optical two-dimensional projection, and three-dimensional imaging.

Abstract: There is provided an article having a reusable writing surface comprising: a planar surface, a water-based film disposed upon the planar surface, wherein the water-based film has a satin finish, and a first UV film over the water-based film, wherein the first UV film has a gloss finish, thereby providing a surface suitable for writing with a dry erasable pen and allowing erasure of the writing.

Abstract: There is provided a method for producing a reusable writing surface comprising: providing a sheet substrate having first and second surfaces; providing a water-based film disposed upon at least one of the first and second surfaces, wherein the water-based film has a satin finish; and providing a first UV film over the water based film, wherein the first UV film has a gloss finish, thereby resulting in a surface suitable for writing with a dry erasable pen and allowing erasure of the writing.

Abstract: There is provided a workbook having a plurality of pages. Each page having a writing surface suitable for writing with a dry erasable pen and allowing erasure of the writing. The writing surface is formed on a substrate by applying layers of film. A particular embodiment uses two film layers. A first layer of water-based UV film is covered with a second layer of UV film having a gloss finish.

Abstract: A wall or roof covering for mounting to a support surface, comprising: a plurality of panels securable to the support surface, each of the panels having a front surface comprising a covering section with simulated building elements, an opposed rear surface facing the support surface when secured thereto, a first marginal edge region and an opposed second marginal edge region, the first marginal edge region having an elongated receiving groove with an elongated aperture oriented one of substantially upwardly and substantially downwardly, the second marginal edge region being at least partially insertable in the first elongated receiving groove of a vertically-adjacent panel and being at least partially covered by a first section of the covering section of the vertically-adjacent panel when inserted therein.

Abstract: A corner assembly for siding and roofing coverings includes two complementary corner molding members, each one of the two corner molding members having a front wall including a covering section with simulated building elements on an outer face thereof. Each one of the two corner molding members further has at least one protruding finger and at least one recess. The at least one protruding finger and at least one recess are configured in an alternate configuration in order to interlock in a male-female configuration when the two complementary corner molding members are engaged with one another to define a corner. A method covers a length of a corner defined at a junction of a first support surface and a second support surface.
