A fountain apparatus (100) includes a submersible pump (1), a water supply pipe (2) including one end connected to a discharge port (13b) of the submersible pump (1), a rotating mechanism (5) including a rotating shaft (51) and a water jet nozzle (50) configured to jet water supplied through the water supply pipe (2), and a support mechanism (4) provided at the other end of the water supply pipe (2) and configured to rotatably support the rotating mechanism (5) via the rotating shaft (51). The water jet nozzle (50) includes a first jet nozzle (53) configured to jet the water in a jetting direction having a propulsive force component in a circumferential direction of the rotating shaft (51).

A holographic projection system and method are implemented by a projection device provided on the vehicle; a water mist generating device for generating water mist provided on the vehicle; and a controller in communication with the projection device and the water mist generating device. The controller is configured to detect a signal of user proximity to the vehicle, and activate the water mist generating device and the projection device respectively based on the detected signal, so that the projection device projects an image onto the water mist.

The present invention is a water fountain control system that utilizes cameras to analyze movements of a human subject, and actuates one or more water fountain controllers in response to the movements to create a display incorporating spray patterns of the flowing water. The camera system records video in real time and generates optical signals that are sent to a processor running software that assesses the dimension, position, stance, and/or motion of the human subject and converts the data into recognized classes of movements and/or poses. Once the processor identifies the type of movements and/or poses, it sends signals to the actuators of the water fountains to control the fountains in a manner that implements stored predetermined visual effects generated by the fountain to create a visual presentation to an audience.

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.
