Patent abstract
A hands-free visual timer enables a person to wash his or hands for the duration of time recommended by the Center for Disease Control. Upon activation, the timer displays an annular ring of thirty triangles and a first icon. After five seconds have passed, a second icon is displayed indicating the user should apply soap. After twenty-five seconds, a third icon is displayed indicating the user should rinse. After thirty seconds, the screen goes blank and all the triangles have disappeared. The central display of triangles is illuminated by a liquid crystal display. The icons are illuminated by light emitting diodes.
