MONITORING SYSTEM AND METHOD
First Claim
1. A monitoring system comprising a first module and a second module, the first module comprising:
- a sensor operable to sense the state of an environment in which the first module is located; and
a first communications device coupled to the sensor and operable to transmit a first signal to the second module indicative of the sensed environment and in response to the sensed state of the environment;
the second module comprising;
a second communications device operable to receive the first signal from the first module;
an alerting device coupled to the second communications device and operable to generate an alert in response to a change in condition of the state of the sensed environment;
a variable timer coupled to the alerting device and operable to delay generation of the alert by the alerting device for a variable predetermined time delay period; and
a controller operable to set the length of the variable predetermined time delay period in response to user input.

Abstract
A monitoring system (10) for monitoring people in swimming pools and other similar environments has a child unit (12) and a parent unit (14) that are in wireless communication with each other. The child unit is intended to be worn by a person near a swimming pool. The child unit includes a water sensor and a proximity sensor that detect when the child unit is immersed in water or when it is removed from the person—potentially hazardous environments. The child unit sends signals to the parent unit indicative of the state of the environment. If the state of the environment is detected as being hazardous, then the parent unit is operable to emit an alarm. The emission of the alarm is delayed by a predetermined time delay, which is variable depending upon the needs of the person being monitored.
