Abstract: Systems and methods provide a user with the ability to mark a surface, easily remove the marking, and remark the same surface. The systems and methods include a marking implement and a mark-receiving surface. When the mark-receiving surface is marked, the resulting mark dries relatively quickly, tends not to smudge, and can be wiped from the surface easily, efficiently and effectively without lasting effect to the mark-receiving surface, which then is available to be marked again.

Abstract: A simple, inexpensive reliable an unobtrusive method of attaching a watch or other timepiece to anything with an edge without damaging the item the watch is attached to. The device is merely twisted onto the edged item (i.e. cap, sleeve, pocket, book, etc.) and placed at the proper angle. The attaching device is a spiral type of apparatus that is attached or molded into the back of the watch. The device is springy enough to open, yet rigid enough to hold the timepiece in place when twisted onto the intended item.

Abstract: A base member has an electrically conductive layer thereon. An electrical power source and indicator device, such as a lamp, buzzer, etc. are electrically connected to the conductive layer. A metallic clip is provided on the base member, also electrically connected to the power source, and spaced from the conductive layer. A question and answer member is mounted on the base member with the clip in electrical connection with a second conductive layer which is part of the question and answer member. The question and answer member has a control opening in registration with a correct answer indicia whereby finger pressure on the correct answer indicia causes an electrical connection to be made between the second conductive layer of the question and answer member and the conductive layer on the base member to complete the electrical circuit to the indicator device. The question and answer member may be an integral or laminated layered structure.

Abstract: A teaching device having a base member with a metallic sheet thereon and a power source and indicator lamp assembly electrically connected to the metallic sheet. A clip is provided on the base member, also connected to the power source, and spaced from the metallic sheet. A question and answer folder is mounted on the base member with the clip in electrical connection with a metallic foil which is part of the question and answer folder. The question and answer folder has a control opening in registration with a correct answer indicia whereby finger pressure on the correct answer indicia causes an electrical connection to be made between the metallic foil of the question and answer sheet and the metallic sheet on the base member to complete the electrical circuit to the indicator lamp.
