Abstract

The present invention relates to a drowning alert transmitter comprising: a) a head component 1 for securing on a swimmer'"'"'s head, b) a head sensor 6A,6B to sense if a swimmer'"'"'s head is inclined back relative the upper torso and to then generate an alert signal, and c) a transmitter 3 connected to the head sensor to transmit an alarm signal upon generation of an alert signal.

Claims

1. A drowning alert transmitter comprising:

a) a head component for securing on a swimmer'"'"'s head,

b) a head sensor to sense if a swimmer'"'"'s head is inclined back relative the upper torso and to then generate an alert signal, and

c) a transmitter connected to the head sensor to transmit an alarm signal upon generation of an alert signal.

2. A drowning alert transmitter according to claim 1, wherein the head sensor includes at least one accelerometer.

3. A drowning alert transmitter according to claim 1 or 2, further comprising a dipping sensor connected to the head component to sense whether a swimmer'"'"'s head is dipping in and out of the water and to then generate an alert signal.

4. A drowning alert transmitter according to claim 3, wherein the dipping sensor measures the conductivity or capacitance of water or air between two electrodes.

5. A drowning alert transmitter according to any preceding claim further comprising a movement sensor to sense absence of translational movement of a swimmer through the water and to then generate an alert signal.

6. A drowning alert transmitter according to claim 5, wherein the movement sensor includes at least one accelerometer.

7. A drowning alert transmitter according to any preceding claim, wherein the drowning alert transmitter further comprises a water sensor to indicate whether the face of a swimmer is in the water for a prolonged period and to generate an alert signal.

8. A drowning alert transmitter according to any preceding claim, wherein the head component is a pair of head goggles.

9. A drowning alert system comprising an alert transmitter according to any preceding claim and a receiver to receive alarm signals from the alert transmitter, said receiver providing an indication means that a swimmer is in difficulty on receipt of an alarm signal.

10. A drowning alert system according to claim 9, wherein the receiver includes means to give directional information of a swimmers location.

11. A drowning alert transmitter substantially as hereinbefore described with reference to and as shown in the accompanying drawings.

12. A drowning alert system substantially as hereinbefore described with reference to and as shown in the accompanying drawings.
