Abstract

The present invention is a toy wand that is activated and controlled by a sequence of motions of the wand while in the hand of an operator. When moved through a specific sequence of motions (herein termed a “spell”, the wand will produce an appealing display of lights whose purpose is to amuse or entertain the wand operator or others in the viewing area. The toy wand comprises a casing, a means for detecting a sequence of motions, one or more lights, and a means for providing time-varying illumination from the lights as a function of the history of motions of the wand

Claims

1. A toy wand for operation by a human comprising:

an elongated casing having a first end and a second end;

a motion detector for detecting motion of said wand;

a means for emitting a human-detectable response;

a microprocessor operably connecting said motion detector and said means for emitting, said microprocessor including;

a first library of target motion sequences;

a motion history buffer for recording a history of said motion extending up to the present;

comparison means for repeatedly comparing said history of said motion with said target motion sequences;

activation means for activating said means for emitting when said comparison means detects a match between said history of said motion extending up to the present and one of said target motion sequences.

2. The toy wand of claim 1 wherein said microprocessor further includes a second library of emitting displays, each of said emitting displays corresponding to one of said target motion sequences, and wherein said activation means activates said means for emitting as per one of said emitting displays, each of said emitting displays corresponding to said one of said target motion sequences.

3. The toy wand of claim 2 wherein said means for emitting is multi-colored light-emitting-diode lights.

4. The toy wand of claim 2 wherein a subset of said library of emitting displays control said emitting means as a function of motion.

5. The toy wand of claim 2 wherein a subset of said emitting displays control said emitting means as a function of time.

6. The toy wand of claim 2 further including a battery for powering said wand and a means whereby said microprocessor determines an absence of said wand motion, said absence causing said wand to enter a battery-conserving mode of operation.

7. The toy wand of claim 2 further including other detectors than said motion detector, said other detectors selected from the group consisting of magnetic, light, and temperature detectors, wherein said other detectors modify said activation means and said emitting displays.

8. The toy wand of claim 1 wherein said motion detector is an accelerometer, said accelerometer mounted to detect acceleration of said first end of said toy wand.

9. A toy wand for operation by a human comprising:

an elongated casing having a first end and a second end;

an orientation detector for detecting orientation of said wand, where said orientation of said wand is defined as the static angular position of the longitudinal axis of said wand with reference to the center of the earth;

a means for emitting a human-detectable response;

a microprocessor operably connecting said orientation detector and said means for emitting, said microprocessor including;

a first library of target orientation sequences;

an orientation history buffer for recording a history of said orientation extending up to the present;

comparison means for repeatedly comparing said history of said orientation with said target motion sequences;

activation means for activating said means for emitting when said comparison means detects a match between said history of said orientation extending up to the present and one of said target orientation sequences.

10. The toy wand of claim 9 wherein said microprocessor further includes a second library of emitting displays, each of said emitting displays corresponding to one of said target orientation sequences, and wherein said activation means activates said means for emitting as per one of said emitting displays, each of said emitting displays corresponding to said one of said target orientation sequences.

11. The toy wand of claim 10 wherein said means for emitting is multi-colored light-emitting-diode lights.

12. The toy wand of claim 10 wherein a subset of said emitting displays control said emitting means as a function of orientation.

13. The toy wand of claim 10 wherein a subset of said emitting displays control said emitting means as a function of time.

14. The toy wand of claim 10 further including other detectors than said orientation detector, said other detectors selected from the group consisting of magnetic, light, and temperature detectors, wherein said other detectors modify said activation means and said emitting displays.

15. The toy wand of claim 9 wherein said orientation detector is an accelerometer, said accelerometer mounted to detect orientation of static angular position of the longitudinal axis of said wand with reference to the center of the earth.
