User activated fountain display
First Claim
1. A user activated display fountain comprising:
- a fountain pool;
detection means disposed in said fountain pool for detecting underwater sound, including sound caused by a user throwing a predetermined object into said fountain pool, said detection means providing a first signal in response thereto;
signal conditioning means couples to said detection means, said signal conditioning means being a means responsive to said first signal for providing a turn-on signal when said first signal has predetermined characteristics;
fountain display control means coupled to said signal conditioning means and said display fountain, said fountain display control means being responsive to said turn-on signal to generate a display sequence in response to said turn-on signal.

Abstract
A sound activated fountain display. A plurality of transducers are disposed on the bottom of the pool of a fountain display with the fountain being normally off. Whenever a coin is tossed into the fountain'"'"'s pool, the sound waves generated by the coin are received by the transducers, activating the fountain display. By gating the responses of the various transducers, the area of the pool in which the coin was tossed may be identified. In this manner, the display may be caused to be directed to that area of the pool, customizing the display for that particular viewer. If desired, the fountain display may be in a central pool with separate "satellite" coin pools surrounding the fountain and for activating the fountain display.
