In one embodiment, a reusable writing kit is disclosed. The kit includes a substrate comprising a substrate writable surface and a substrate rear surface and a panel releasably mountable to the substrate. The panel includes a panel writing surface, a panel rear surface, and a first attachment member having a first type of securing force operable to mount the panel to the substrate, where the panel is mounted to the substrate and the panel rear surface is spaced apart from the substrate writable surface.

The present invention relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions.

A magnetic display unit includes: a display layer; a magnetic layer located behind the display layer; and a quick-release mechanism including an activator, wherein the quick-release mechanism is adapted to increase the distance between the magnetic layer and the display layer such that, when activated by the activator, the quick-release mechanism causes any magnets located along the display layer to be released from the display layer.

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.

According to an embodiment of the present invention, there is provided a magnet screen device, comprising a casing having an opening, a roll rotatably placed in the casing, and a magnet screen, the magnet screen being configured to be wound on the roll during a storage of the magnet screen and configured to be pulled out from the opening of the casing and to be attached to an installation surface upon an use of the magnet screen, wherein the magnet screen device further comprises a bar part at a region where the opening is provided, and wherein the bar part is configured to be capable of contacting the magnet screen at the region where the opening is provided.

In one embodiment, a reusable writing panel including a writing surface and attachment mechanisms is disclosed. The writing panel may include a stacked layer configuration, having a front or first layer defining a writing surface and a rear or second layer defining a connection surface, with an optional spacer layer positioned therebetween. The connection surface may include one or more attachable or securable elements, such as a first attraction element and a second attraction element, that may generate different types of attraction forces, e.g., magnetic and suction. This variation in connection types allows the panel to be securable to various types of objects or surfaces, e.g., magnetic and non-magnetic surfaces.
