eraser tool for white boards. The wiper blade
eraser can be used as a stand alone or it can be
adapted onto an existing marker, as it has
various cross-sections. This patent is not the
entirety of our invention but is a critical part
in terms of eraser design for the automated
whiteboard wiper to have the least amount of
friction and the highest removal efficiency with
the lowest number of passes.
