The present invention provides tablets with interconnection features and a system of multiple tablet assemblies removably interconnected to one another. The tablets may be removably mounted to a vertical surface or positioned on a horizontal surface. Features of the present invention allow a user to remove or move one tablet from the system without disrupting or moving the other tablets.

Electro-optic, especially electrophoretic, displays are used in variety of architectural and furniture applications, including a tile (100) comprising an electro-optic layer (110) capable of changing the color of the file, front and multiple rear electrodes and a light-transmissive polymeric layer (102), the exposed surface of which is textured to provide a plurality of facets inclined to the plane of the tile (100), the rear electrodes being aligned with the facets. A variable color writable board is also provided.

A display device is described which can be updated by applying pressure with a passive object. The display device comprises a transparent top conductor layer, a middle conductor layer and a bottom conductor layer. The middle conductor layer is segmented into a plurality of independent areas and a pixel of the display device is defined based at least in part on the way that the middle conductor layer is segmented. The display device further comprises an electrophoretic ink layer between the top and middle conductor layers, a layer of piezo-electric material between the middle and bottom conductor layers, and an electrical connection between the bottom and top conductor layers.

A frame-type air purifier includes a purifier housing, a main frame and an image board. The purifier housing has a back plate and a front plate configured opposite to each other. The back plate has a wall positioner configured thereon. The front plate includes a first quick-demounting member configured thereon. The main frame has a central hollow and a second quick-demounting member configured thereon. The image board includes a baseboard and an imaging sheet configured on the baseboard, wherein the baseboard has a third quick-demounting member configured thereon. The first quick-demounting member of the purifier housing selectively assembles with the second quick-demounting member of the main frame correspondingly, or selectively assembles with the third quick-demounting member of the image board correspondingly.

A display assembly, having a base comprised of polymeric material, and having a front wall of at least one hundred square centimeters in area, and a rearward-extending base peripheral wall of at least 0.5 cm height. The front wall has raised regions and recessed regions that extend at least as far back as the peripheral wall at its furthest rearmost extent, so that when the base is placed against a flat surface the back of the recessed regions touches the flat surface. A polymeric cover is adapted to tension fit to the base, the polymeric cover including a generally transparent front wall. Translucent display media interposed between the base and the cover and a set of energy efficient lighting devices disposed in the recessed regions.

A slope adjustable illuminated art and drafting table for drawing, writing, or impromptu sketching on large documents enables efficient access and storage of artistic or drafting supplies. The art and drafting table provides a base supported by a pair of arced legs. A work surface overlays the base. The work surface is illuminated and pivotally adjustable to slope between 0 and 35. A hinged angle adjustment bracket fastens the work surface at the desired slope. The drafting table provides modular lower drawers that are interchangeable between left and right sides of the drafting table; an extendable shelf having a longitudinal lip for retaining marking instruments; and a pair of elongated partitioned lateral trays at the lateral edges of the work surface. The partitioned lateral trays are detachable and have depressions for holding artist instruments, paints, writing instruments, and other materials used by artist and draftsmen.
