Abstract: A keypad for interacting with a computer system having a display screen. The keypad includes a substantially planar base surface. A numeric/control key cluster is positioned on a first half of said planar base surface. The numeric/control key cluster incudes a 10-digit numeric key set, a plurality of cursor movement keys, and a plurality of control keys. A screen select key cluster is positioned on a second half of said planar base surface. The screen select key cluster includes a plurality of control keys for controlling display of information on the display screen.

Abstract: Protective coating systems are reinforced by first laying a suitable mesh screen of plastic, metal or the equivalent on the surface to be protected. Thereafter, a thin layer of a coating composition, e.g., a latex cement, is poured over the mesh and allowed to set. In this operation the mesh is bonded by means of the coating composition to said surface. The screen also protrudes to the upper surface of said layer and when the latter has been allowed to set, a second layer is applied resulting in a system in which the reinforcing mesh not only aids in forming a durable bond between said first layer and said surface, but also likewise renders the two layers thus formed resistant to spalling or separating caused from expansion or contraction of said surface.
