Device for detecting a body fall into a pool
First Claim
1. ) A method for detecting the entry of a body into a pool comprising the following steps in any order:
- sensing of water condition in said pool using a water condition sensor;
acquiring and storing the water condition information;
processing of said water condition informationto filter said water condition information using a filter,to determine a change in filtered data, andsending an alarm signal to an alarmwhen a predetermined body entrance criterion is exceeded.

Abstract
This invention relates to a water condition indication system for a swimming pool comprising a water condition sensor (110), a memory (130) and a processor (140) and alarm (150). The memory collects and stores the information. The data processor filters the water condition information, corrects for perturbations, and generates an alarm when a body fall into a pool causes a change in the water condition that exceeds a predetermined body entrance criterion. Analysis of the output of one or more filters reduces the occurrence of false alarms while still providing a substantially rapid response time under the prevailing conditions.
