Abstract

A device comprising a plurality of conductive probe pairs, a control unit coupled to said probe pairs and a power source to supply said control unit with power, wherein each of said probe pairs is activated when bridged by a conductive liquid thus forming a closed circuit, said control unit registers activation of said probe pairs and said control unit is designed to actuate at least one pre-determined response, said response being dependent on the order in which each of said probe pairs is activated.

Claims

1. A device comprising:

(a) a plurality of conductive probe pairs;

(b) a control unit coupled to said probe pairs; and

(c) a power source to supply said control unit with power;

wherein each of said probe pairs is activated when bridged by a conductive liquid thus forming a closed circuit, said control unit registers activation of said probe pairs and said control unit is designed to actuate at least one pre-determined response, said response being dependent on the sequence in which at least two of said probe pairs are activated.

2. The device according the claim 1, wherein said pre-determined response is dependent on the order in which each of said probe pairs is activated or deactivated.

3. The device according to claim 1, wherein said control unit and said power source are disposed in one or more liquid impervious housings while exposing said conductive probe pairs to the exterior of the device.

4. The device according to claim 1, wherein said pre-determined response comprises emitting a sound and the device further comprises a speaker coupled to said control unit.

5. The device according to claim 1, wherein said pre-determined response comprises emitting light and the device further comprises a light emitter coupled to said control unit.

6. The device according to claim 1, wherein said pre-determined response comprises movement and the device further comprises a motor coupled to said control unit.

7. A toy comprising:

(a) a cavity;

(b) at least one aperture in the toy that allows for the movement of liquid from the exterior of said toy into said cavity

(c) a device housed within said cavity comprising;

(i) a plurality of conductive probe pairs;

(ii) a control unit coupled to said probe pairs; and

(iii) a power source to supply said control unit with power;

wherein each of said probe pairs is activated when bridged by a conductive liquid thus forming a closed circuit, said control unit registers activation of said probe pairs and said control unit is designed to actuate at least one pre-determined response, said response being dependent on the sequence in which at least two of said probe pairs are activated.

8. The toy according to claim 7, wherein said predetermined response comprises emitting a sound and the device further comprises a speaker coupled to said control unit.

9. The toy according to claim 7, wherein said device forms a physical partition to divide said cavity into first and second compartments and said partition is substantially impervious to liquid.

10. The toy according to claim 9, wherein the plurality of conductive probe pairs are disposed within said first compartment and said at least one aperture allows the movement of liquid from the exterior of said doll into said first compartment.

11. The toy according to claim 10, wherein said predetermined response comprises emitting a sound, the device further comprises a speaker coupled to said control unit, said speaker is disposed within said second compartment and said second compartment further comprises a hole to allow sound from the speaker to escape.

12. The toy according to claim 7, wherein said toy is a doll.

13. A device comprising:

(a) at least one conduit comprising at least one opening;

(b) a plurality of conductive probe pairs disposed within said conduit;

(c) a control unit coupled to said probe pairs; and

(d) a power source to supply said control unit with power;

wherein each of said probe pairs is activated when bridged by a conductive liquid thus forming a closed circuit, said control unit registers activation of said probe pairs and said control unit is designed to actuate at least one pre-determined response, said response being dependent on the sequence in which at least two of said probe pairs are activated.

14. The device according the claim 13, wherein said pre-determined response is dependent on the order in which each of said probe pairs is activated or deactivated.

15. The device according claim 13, wherein said conduit further comprises at least one reservoir that further comprises a valve to empty said reservoir.

16. The device according to claim 13, wherein said control unit and said power source are disposed in one or more liquid impervious housings.

17. The device according to claim 13, wherein said pre-determined response comprises emitting a sound and the device further comprises a speaker coupled to said control unit.

18. The device according to claim 13, wherein said pre-determined response comprises emitting light and the device further comprises a light emitter coupled to said control unit.

19. The device according to claim 13, wherein said pre-determined response comprises movement and the device further comprises a motor coupled to said control unit.

20. A toy comprising:

(a) a cavity;

(b) at least one aperture in the toy associated with said cavity;

(c) a device housed within said cavity comprising;

(i) at least one conduit for receiving liquid comprising at least one opening, each opening disposed in a said aperture;

(ii) a plurality of conductive probe pairs disposed within said conduit;

(iii) a control unit coupled to said probe pairs; and

(iv) a power source to supply said control unit with power;

wherein each of said probe pairs is activated when bridged by a conductive liquid thus forming a closed circuit, said control unit registers activation of said probe pairs and said control unit is designed to actuate at least one pre-determined response, said response being dependent on the sequence in which at least two of said probe pairs are activated.

21. The toy according to claim 20, wherein said pre-determined response comprises emitting a sound and the device further comprises a speaker coupled to said control unit.

22. The toy according to claim 20, wherein said device forms a physical partition to divide said cavity into first and second compartments and said partition is substantially impervious to liquid.

23. The toy according to claim 22, wherein said pre-determined response comprises emitting a sound, the device further comprises a speaker coupled to said control unit, said speaker is disposed within said second compartment and said second compartment further comprises a hole to allow sound from the speaker to escape.

24. The toy according to claim 20, wherein said toy is a doll.
