Aquatic timing systems are designed to automate the process of timing, judging, and scoring in competitive swimming and other aquatic sports, including diving, water polo, and synchronized swimming. [1] These systems are also used in the training of athletes, and many add-on products have been developed to assist with this process. [2]

[2] The general distinction between pools/ponds and lakes is vague, but Brown [1] states that ponds and pools have their entire bottom surfaces exposed to light, while lakes do not. In addition, some ...
Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms. [1]
