Abstract

An illumination poi is provided, comprising light emitters and light waveguides optically coupled to the light emitters. In some embodiments, the light waveguides are optical fibers. A microchip light controller, associated with the light emitters, varies the light entering the optical fibers, and facilitates spectacular light pattern upon rotation of the illumination poi in the dark.

Claims

1. A poi weight including:

i) a casing;

ii) one or more light emitters mounted inside said casing;

iii) one or more light waveguides, each of said light waveguides having a proximal end optically coupled to at least one of said light emitters and a distal end disposed outside that casing, said distal end being configured to scatter light propagating in the light waveguide; and

iv) one or more light controllers associated to said one or more light emitters and configured to vary at least one parameter of the light entering into said one or more light waveguides.

2. The poi weight of claim 1, further comprising a suspension element which is attached to the weight.

3. The poi weight of claim 1 wherein the weight has at least one cross section roughly shaped as an ellipse.

4. The poi weight of claim 1 wherein the casing is made of a translucent material.

5. The poi weight of claim 1 further comprising an elastic sheath disposed over the casing for absorbing at least part of a shock occurring as a result of a collision between the weight and an entity.

6. The poi weight of claim 1 wherein the casing comprises two compartments and having an open state, in which state a user may dispose detachable objects within one of the compartments.

7. The poi weight of claim 1 wherein said one or more light emitters comprise one or more light emitting diodes.

8. The poi weight of claim 1 wherein the one or more light emitters are powered by one or more rechargeable batteries disposed within the casing.

9. The poi weight of claim 1 wherein the light controller is loaded with two or more illumination programs.

10. The poi weight of claim 1 further comprising a motion sensor associated with the light controller, and wherein the light controller varies at least one parameter of the light entering into one or more light waveguides in accordance with one or more parameters of weight motion.

11. The poi weight of claim 1 wherein at least one of the light controllers is configured to receive one or more parameters of motion data, the light controller varying at least one parameter of the light entering into one or more light waveguides in accordance with said one or more parameters of the motion data.

12. The poi weight of claim 1 further comprising a switch and a suspension element attached to the switch, said switch being configured such that, when the suspension element pulls the switch, the switch is turned on, thereby activating the light controller.

13. The poi weight of claim 1 wherein the one or more light waveguides comprise one or more optical fibers.

14. The poi weight of claim 1 wherein the light waveguides comprise two groups of optical fibers, a first group of optical fibers of a first substantially equal length, and a second group of optical fibers of a second substantially equal length, the first length being greater than the second length.

15. The poi weight of claim 1 wherein the light emitters comprise a first light emitter emitting a first color, and a second light emitter emitting a second color.

16. The poi weight of claim 1 wherein the light emitters comprise a first light emitter emitting a first color, and a second light emitter emitting a second color, the light emitted of the first emitted being intermixed with the light emitted of the second light emitter causing a color perception in accordance with a colorimetric blend of the two colors.

17. The poi weight of claim 1 further comprising a communication interface connecting at least one of the light controllers to a device residing outside the weight.

18. The poi weight of claim 1 wherein the light emitters comprise one or more visible laser diodes.

19. The poi weight of claim 1 further comprising a rotation data sensor measuring one or more rotation parameters and transferring said one or more rotation parameters to said light controller, said light controller varying one or more parameters of light entrance to the light waveguides in accordance with said one or more rotation parameters.

20. The poi weight of claim 1 wherein another poi weight of approximately same weight and external shape is connected to said poi weight, the two poi weights being parts of a symmetric poi.

21. The poi weight of claim 1 further comprising at least one flat light waveguide, the flat waveguide has a proximal end configured for efficient optical coupling with at least one light emitter, and has a distal end configured to scatter light outside the casing in a wide light trail.

22. A method for enabling a person to perform illumination poi moves, the method comprising the steps of:

a) providing the person with an illumination poi, said illumination poi comprising;

i) a suspension element;

ii) a weight connected to said suspension element, the weight including

A) a casing;

B) one or more light emitters mounted inside casing;

C) one or more light waveguides, each light waveguide having a proximal end optically coupled to at least one light emitter and a distal end disposed outside the casing and scattering light propagating in the light waveguide; and

D) one or more light controllers varying automatically at least one parameter of the light entering into one or more light waveguides.

and

b) allowing the person to perform illumination poi moves.

23. The method of claim 22 wherein the person determines one or more parameters of the spectacular light patterns by maneuvers conducted in accordance with the variation by a light controller of one or more parameters of the light entering the light waveguides.

24. The method of claim 22 further comprising the step of coding a color varying time sequence in an illumination program using the illumination poi and a computing device connected to the illumination poi.
