A method of reusing a notebook provides a notebook having a synthetic-paper page. The method also provides a thermochromic ink pen which, when used to write on the synthetic paper page, leaves thermochromic ink markings. The method further provides a moisture carrier configured to have a liquid diffused therein. The moisture carrier is configured to erase the thermochromic ink markings from the synthetic-paper page by contacting the thermochromic ink markings when the moisture carrier is moist. The method then writes with thermochromic ink on at least a portion of the synthetic-paper page. Liquid is diffused in the moisture carrier, and the portion of the synthetic-paper page having the thermochromic ink is wiped with the moist moisture carrier, such that the thermochromic ink is erased from the synthetic-paper page.

A series of devices that allow for embedding of an image as a background while also affording the user the ability to write and print on the surface, with erasable capabilities, thus providing a multifunctional product for use in numerous industries. The devices are manufactured from predominately corrugated plastic. In one embodiment a one piece, removably attachable, cabinet system and graphic display system. In an additional embodiment, a writable board, or peg board comprising a front panel and a rear panel wherein the panels are interconnected by parallel rows, or corrugations, these panels include a writable and erasable surface. The present invention relates to assemblies of corrugated systems to better serve personal, business, and educational needs.

Articles are described comprising a surface layer comprising at least one long hydrocarbon chain silane compound (C8-C36) bonded to a siliceous layer such as diamond-like glass. In an embodiment, the siliceous layer has a porosity of no greater than 10% and a thickness no greater than 1 micron. In another embodiment, the siliceous layer comprises 10-50 atomic percent carbon and the article further comprises an organic polymeric base member or a hardcoat layer. Also described are coating compositions comprising at least one C8-C17 hydrocarbon silane compound and at least one C18-C36 hydrosilane compound.

An erasable writable material for large format applications is disclosed, and includes a cast polyvinylchloride film with a mount surface opposite an etched receiver surface. Also incorporated is a transparent polyester film that has a marking side with a hardness exceeding approximately shore D 79 and an opposite seal side, hermetically laminated to the receiver surface. The marking side includes a clear superstrate that has a hardness exceeding approximately shore D 90, which is applied to the marking side of the polyester film to lower surface energy below about 24 millinewtons per meter. The receiver surface is treated to have a surface energy exceeding about 45 millinewtons per meter, to enable improved adherence of printed and preformed graphic elements, which are encapsulated when laminated between the PET film and receiver surface. The superstrate includes a perfluoropolyether, a polyurethane, an acrylated polyurethane, and/or an acrylate resin to harden the material.

An electronic whiteboard system, an operating method and an electronic whiteboard are provided. The electronic whiteboard system includes an electronic whiteboard and an electronic device. The electronic whiteboard includes a functional area. The electronic device is coupled to the electronic whiteboard and includes a display. The electronic whiteboard receives a touch input to generate coordinate information corresponding to the touch input. The electronic whiteboard transmits the coordinate information to the electronic device. The electronic device receiving the coordinate information determines whether the coordinate information is located in the functional area of the electronic whiteboard. If yes, the electronic device executes a function corresponding to the coordinate information. If not, the electronic device displays the touch input corresponding to the coordinate information on the display. The electronic whiteboard system, the operating method and the electronic whiteboard of the invention are adapted to improve convenience and functionality of the electronic whiteboard.
