<P>PROBLEM TO BE SOLVED: To provide a low-cost and low-power system for selectively visualizing an image such as a static printed image of notice, advertisement, etc. <P>SOLUTION: The system for selectively visualizing image includes a transitioning assembly that is configured to be retrofit with an existing dispenser. The transitioning assembly includes a transitioning window that is coupled to a switch. The switch is configured so as to be attached to an actuator provided by the dispenser while operably contacting with the actuator. Upon the engagement of the actuator, the switch is triggered, thereby, the transitioning window transitions from at least partially opaque state to an at least partially transparent state and, as the result, an image behind the transitioning window becomes visible for an observer. <P>COPYRIGHT: (C)2010,JPO&INPIT |
