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.

An eraser includes a body portion defining a plurality of passages configured to hold a plurality of writing implements. The eraser may further include an eraser portion forming a side of the body portion. The eraser may further include an attachment portion forming a second side the body portion. The attachment portion may be configured to releasably secure the eraser to a writable surface formed from a non-magnetic material. An eraser kit may include the eraser and a plurality of writing implements. In a first configuration, the eraser may releasably secured to a writable surface using the attachment portion. In a second configuration, the eraser may be engaged with the writable surface to modify markings using the eraser portion.

Mobile training labs for training gas technicians are disclosed. The mobile training labs can include a towable trailer comprising a body having a plurality of walls at least partially defining a hollow interior, an axle having at least two wheels disposed thereon to support the body, and a tow hitch. The mobile training labs can also include at least one training bay connected to the towable trailer such that the at least one training bay is configured to be accessed from an exterior of the towable trailer. The at least one training bay can include a work bench and a mock service entrance that is representative of a commercial or residential gas service entrance.

A whiteboard includes a whiteboard support and a board body, the whiteboard support includes two support rods arranged in parallel with each other, and each of them is formed by rigidly connecting the first tube body and the second tube body, can be detached one by one, and then stored. Compared with the one-piece support rod of the conventional whiteboard, the whiteboard according to the present embodiment greatly reduces the occupied area and reduces the difficulty in transportation, and the transportation cost for the enterprise. Meanwhile, by providing at least two insertion slots at different heights on the side of the support rod facing the board body, the board body of the whiteboard can be adjusted in height so as to adapt to use of people of different heights.

A tablet-like device is configured to have a slightly negative buoyancy and to hold a sheet of waterproof synthetic paper, or another removable, waterproof recording sheet, onto which notes or messages or sketches can be recorded via a writing implement, in an underwater or marine environment, or another extreme or severe environment. Since the tablet device is configured for use of sheets of waterproof synthetic paper, divers can work with their own personal pre-printed material underwater. Further, the tablet device also has the advantages of cost savings and reduced environmental impact.

The invention is directed to a system of presenting and displaying information in a home office or executive environment. The system includes an outer casing that houses a plurality of pull-down screens. In use, the screens can be extended in a downward direction from the open lower face of the casing. Advantageously, the assembly provides a storage configuration where a plurality of pull-down screens are hidden from view within the interior of the casing. The assembly also includes a use configuration where one or more screens extend from the bottom face of the casing, allowing information/ideas to be exchanged and conveyed.
