A self-adhesive and reusable support for notes is disclosed. The support comprises a flat laminar body (1-1-1) that in turn comprises a first flat surface (10) and a second flat surface (11) opposite from the first surface. The flat laminar body comprises micro suction cups (3) distributed in a staggered pattern on the first flat surface and a writable surface (4) on the second surface. The self-adhesive and reusable support for notes is manufactured from opaque polymeric calendered vinyl. The support is reusable, meaning that it can be used as many times as desired, without the risk of losing the self-adhesive properties thereof even when the location thereof is constantly changed, as well as writing with marker or highlighter and erasing it again. Due to the nature thereof, it is especially suitable for use in the Kanban method.

Disclosed is a coating composition suitable for coating onto a wall or other substrate to yield a dry-erase coating. The composition may be prepared by providing an aminoalkoxysilane, and in the substantial absence of water, reacting a portion of the aminoalkoxysilane with a carbonate and reacting a portion of the aminoalkoxysilane with an epoxy compound. These reactions will result in a coating composition that comprises a mixture of alkoxysilylamines and alkoxysilylcarbamates. The coating composition can also include an alkyl amine in an amount effective to catalytically deprotect alkoxy groups to yield silanol groups, facilitating fast crosslinking.

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.

Present invention is a learning game and apparatus that focuses on improving the mastery of object permanence, language and vocabulary development, humor development, and complex imaginative play abilities in young children. This game and apparatus has many variations to accommodate play by infants, toddlers, preschoolers, and children of varying ages in their language and humor development, and is ideal for young children as no reading is required. The game provide a means to teach infants and young children sign language. Still further, in a particularly certain embodiment the game invention is easily employable by children with developmental disabilities due to the limited need to manipulate playing pieces. The game play allows variations for embodiments of the game to be played with one game leader and one game player, however, there is no limit to the number of players that can play, and children of all ages can play together.

According to an embodiment, an information processing device includes a memory having computer readable instructions stored thereon and at least one processor. The at least one processor is configured to execute the computer readable instructions to: set, in response to an instruction from a first terminal device, task information containing a task and a request for an answer to the task; present, in the first terminal device, a user interface meant for inputting the instruction; manage the task information; and receive the answer which is sent from a second terminal device and which is associated to the task included in the task information that is obtained by the second terminal device. For each of sets of identification information enabling identification of the second terminal device that sent the answer, the at least one processor further manages the received answer in a corresponding manner to the task information containing the task.

A panel assembly including a panel and at least one base member for supporting the panel. The at least one base member is configured between a stored position and a use position. The assembly further includes a locking mechanism, the locking mechanism configured to secure the at least one base member to the panel in the use position.

A dry erase writing surface has a low gloss level of 35-60 that can be utilized as both a writable/erasable dry erase surface and a projection surface, formed by a single component, 100% solids polyurethane, ambient cured, dry erase paint formulation. The paint formulation includes a low NCO isocyanate, a cure accelerating catalyst, a flow, leveling, and defoaming agent, a silica matting agent to reduce the gloss level of the applied coating, and an aliphatic hydrocarbon. The surface is ready for use in 24 hours. The coating has a low VOC of between 49 g/l and 99 g/1. The coating is applied to a prepared surface of a substrate to form a film thickness of 1-3 mils. Marks on the dry erase surface remain virtually invisible after 2500 cycles.
