Underwater swimming pool illumination systems - Patent 4053758 (5758 words) |
 | An underwater swimming pool illumination system includes a lighting assembly having a lamp unit installed within its rear portion in a waterproof enclosure; and the lamp is connected to a low voltage battery. |
| In a normal installation of a swimming pool lighting assembly 10 or 22 according to this invention, the assembly is installed at the swimming pool by being fitted to a pad 16 or 16.1 respectively, which is in turn, secured to the swimming pool deck 18. |
| The bayonet-like assembly of the base to a pad which is secured to the swimming pool deck assists in overcoming or absorbing the force of a rocking motion which may be imposed upon the lighting assembly due to the wave action of water in the swimming pool. |
| Computational fluid dynamics ? A tool for future swimming technique analysis (3012 words) |
| The underwater phase of swimming forms a large component of the total event time in modern swimming and can often lead to the difference between a medal and finishing with the rest of the pack. |
| To make this model specific to elite swimming performance, it is necessary to apply the movement patterns which are typical of an elite swimmer with a proficient underwater dolphin kicking technique. |
| Due to the unavailability of empirical testing to accurately measure drag while swimming throughout an underwater kick cycle, the model was calibrated using steady- state tests (passive drag recorded while in a prone streamlined position). |
