Abstract

Proximity triggered water fountains may have proximity sensors configured to detect target(s), a processing unit communicably coupled to proximity sensors configured to transfer data related to the target(s) to the processing unit, nozzles and nozzle controllers, and collectors configured to receive water projected from the nozzles. The nozzle controllers may be controlled based on data received from the sensors. The nozzle controllers may be coupled to the nozzles of a water circulation system configured to adjust a water projection angle from the nozzles with respect to the ground. The water circulation system may use tank(s), pump(s), and supply and return line(s), with the nozzles, tank(s), pump(s), and supply and return line(s), being in fluid communication. The nozzles and collectors may be displaced a horizontal distance from each other such that outlets of the nozzles are not vertically above the collectors.

First claim

1 . A proximity triggered water fountain, comprising:
a first proximity sensor configured to detect at least one target; a second proximity sensor configured to detect the at least one target; a processing unit with which the proximity sensors are communicably coupled, the proximity sensors being further configured to transfer data related to the at least one target to the processing unit; a first nozzle and a first nozzle controller; a second nozzle and a second nozzle controller; and a first collector configured to receive water projected from the first and/or second nozzles, wherein the processing unit is communicably coupled to the nozzle controllers, wherein the nozzle controllers are configured to be controlled according to the data received from the proximity sensors, wherein the nozzle controllers are mechanically coupled to the nozzles of a water circulation system configured to adjust a water projection angle from the nozzles with respect to a plane orthogonal to gravity, wherein the water circulation system comprises a tank, a pump, a supply line, and a return line, the nozzles, tank, pump, supply line, and return line being in fluid communication with each other, and wherein the nozzles and the collector are displaced a horizontal distance from each other in a direction parallel to the plane orthogonal to gravity such that outlets of the nozzles are not vertically above the collector.

2 . The fountain of claim 1 , wherein the collector has a conic shape.

3 . The fountain of claim 1 , wherein the collector has a hemispheric shape.

4 . The fountain of claim 1 , wherein the collector has an urn shape.

5 . The fountain of claim 1 , wherein the collector is configured to receive a volume of water projected at least the horizontal distance from the nozzles, and wherein the collectors are in fluid communication with the return line.

6 . The fountain of claim 1 , further comprising:
a third nozzle and a third nozzle controller; a fourth nozzle and a fourth nozzle controller; and a second collector configured to receive water projected from the third and fourth nozzles.

7 . The fountain of claim 1 , comprising at least 10 of the nozzle controllers and at least 5 of the collectors.

8 . The fountain of claim 7 , wherein the collectors are arranged substantially linearly to each other along a first line,
wherein the nozzles are arranged substantially linearly to each other along a second line, wherein the first and second lines are horizontally displaced from each other and parallel to each other, such that the collectors are arranged opposite and in parallel to the nozzles.

9 . The fountain of claim 1 , wherein the nozzles are configured to project water in a jet direction including both an upward vertical and a horizontal component.

10 . The fountain of claim 1 , wherein the first and second nozzles are arranged to project water in a coplanar manner towards the first collector, with a first water stream from the first nozzle being vertically above a second water stream from the second nozzle.

11 . The fountain of claim 10 , wherein the first and second nozzles are arranged on a common hinge, such that there is an angle between the first and second nozzles.

12 . The fountain of claim 1 , wherein the first and second nozzles are vertically no higher than the collector.

13 . The fountain of claim 1 , wherein the water projection angle from the nozzles increases with a decreasing distance to the at least one target, the water projection angle of the nozzles having a maximum of 70° with respect to the plane orthogonal to gravity, and
wherein the decreasing distance is determined by the proximity sensors.

14 . The fountain of claim 1 , wherein the water projection angle from the nozzles decreases with an increasing distance to the at least one target, the water projection angle of the nozzles having a minimum of 30° with respect to the plane orthogonal to gravity, and
wherein the increasing distance is determined by the proximity sensors.

15 . The fountain of claim 1 , wherein the water projection angle of each of the nozzles is independent to each other.

16 . The fountain of claim 1 , comprising at least three of the proximity sensors.

17 . The fountain of claim 1 , wherein the tank is surrounded on all sides by walls such that water cannot evaporate from the tank, the fountain obtaining at least 50 wt. % of its water from the tank.

18 . The fountain of claim 1 , configured to draw water only from the tank, wherein the tank draws water from a municipal source.

19 . A method of operating a water system, the method comprising:
detecting the motion of a human with the fountain of claim 1 ; and projecting water from the nozzles to the collectors.

20 . A method of conserving water during use of a fountain, the method comprising:
projecting water from a nozzle to a collector across a horizontal displacement and a vertical displacement, while collecting at least 95 wt. % of the water projected in the collector, wherein the fountain comprises proximity sensors configured to detect at least one target, a processing unit with which the proximity sensors are communicably coupled and to which the proximity sensors are configured to transfer data related to the at least one target, a plurality of the nozzles, nozzle controllers, and collectors configured to receive water projected from the nozzles, the processing unit being communicably coupled to the nozzle controllers, the nozzle controllers being controllable according to the data received from the proximity sensors,
the nozzle controllers being mechanically coupled to the nozzles of a water circulation system configured to adjust a water projection angle from the nozzles with respect to a plane orthogonal to gravity, and
wherein the water circulation system comprises a tank, a pump, a supply line, and a return line, the nozzles, tank, pump, supply line, and return line being in fluid communication with each other without a body of water exposed to the environment besides the water projected.
