Abstract

A motor control system is provided for controlling a speed of a motor system used in a musical instrument. The motor control system includes at least one sensing device attached to the musical instrument, and configured for detecting movement of an object and providing a sensor signal based on the movement of the object. Also included in the motor control system is a control unit having a processor connected to the motor system and the at least one sensing device. The control unit is configured for selectively modulating the speed of the motor system based on the sensor signal.

First claim

What is claimed is:

1. A motor control system for controlling a motor system, the motor control system comprising:
at least one sensing device attached to a musical instrument and configured to detect movement of an object and generate a sensor signal from the at least one sensing device based on the movement of the object; and
a control unit comprising:
a processor connected to the motor system and the at least one sensing device;
a signal interpretation profile adjustment unit configured to interpret the sensor signal based on a signal interpretation profile; and a motor speed modulation unit configured to generate a motor signal for modulating a speed of the motor system by converting the sensor signal based on the signal interpretation profile.

2. The motor control system of claim 1 , wherein the at least one sensing device includes at least one of: a motion-detecting camera, an infra-red sensor, an ultrasound sensor, a motion-tracking camera, and a motion-capturing sensor.

3. The motor control system of claim 1 , wherein the control unit further comprises a signal detection and calibration unit configured to detect the sensor signal from the at least one sensing device, and provide movement condition information about the object.

4. The motor control system of claim 1 , wherein the control unit further comprises a distance estimation unit configured to estimate a distance between a corresponding sensing device and the object based on the sensor signal.

5. The motor control system of claim 1 , wherein the control unit further comprises a signal tracking unit configured to track the sensor signal to monitor the movement of the object during a predetermined time period.

6. The motor control system of claim 1 , wherein the control unit further comprises a motor activation unit configured to activate the motor system based on the motor signal, and modulate the speed of the motor system based on the motor signal.

7. A method of controlling a motor system, the method comprising:
detecting, at least one sensing device attached to a musical instrument, movement of an object;
generating, by the at least one sensing device, a sensor signal based on the movement of the object;
interpreting, by a control unit, the sensor signal based on a signal interpretation profile; and
modulating, by the control unit, a speed of the motor system by converting the sensor signal based on the signal interpretation profile.

8. The method of claim 7 , further comprising interpreting a relationship associated with at least one of: a distance between the object and the at least one sensing device, and a speed of the object, the relationship being interpreted based on a voltage level of the sensor signal.

9. The method of claim 8 , wherein interpreting the relationship comprises estimating the distance between the object and the at least one sensing device based on the voltage level of the sensor signal.

10. The method of claim 7 , further comprising detecting the sensor signal from the at least one sensing device and providing movement condition information about the object relative to the at least one sensing device.

11. The method of claim 10 , wherein detecting the sensor signal comprises tracking the sensor signal for monitoring the movement condition information of the object during a predetermined time period to evaluate change information of the movement condition.

12. The method of claim 11 , wherein tracking the sensor signal comprises calculating a sensor signal strength based on the tracked sensor signal with respect to the change information using the voltage level of the sensor signal.

13. The method of claim 7 , further comprising generating a motor signal for modulating the speed of the motor system.

14. The method of claim 13 , wherein generating the motor signal comprises activating the motor system based on the motor signal, and modulating the speed of the motor system based on the motor signal.

15. A method of controlling a motor system, the method comprising:
detecting, by at least one sensing device attached to a musical instrument, movement of an object;
generating, by the at least one sensing device, a sensor signal based on the movement of the object;
generating, by a control unit, a signal interpretation profile having movement condition information associated with the object based on a voltage level of the sensor signal;
interpreting, by the control unit, the sensor signal based on the signal interpretation profile; and
modulating, by the control unit, a speed of the motor system by converting the sensor signal based on the signal interpretation profile.

16. The method of claim 15 , further comprising adjusting the speed of the motor system based on a sensor signal strength of the sensor signal with respect to the signal interpretation profile.

17. The method of claim 16 , wherein adjusting the speed of the motor system comprises adjusting the signal interpretation profile to modify at least one of: a range of the at least one sensing device, the sensor signal strength of the sensor signal, and the speed of the motor system.

18. The method of claim 15 , further comprising converting the sensor signal based on the signal interpretation profile and generating a motor signal for modulating the speed of the motor system.
