Automatic calibration of an imbalance detector
Methods and apparatus for a centrifuge control system, which are particularly suited for automatically calibrating a centrifuge imbalance detector that include an accelerometer and a controller. The controller is configured to automatically calibrate imbalance limits. Upon determining these limits, the controller assigns these limits or values to the accelerometer.
1. An imbalance calibration control system, comprising a centrifuge;
an accelerometer acting as an imbalance detector;
a controller that automatically calibrates imbalance limits of the centrifuge and assigns these limits to the imbalance detector; and
a rotor connected to a gyro in communication with a motor drive shaft.
2. The system of claim 1 , wherein said imbalance detector is connected to said controller.
3. The system of claim 1 , wherein said rotor, said gyro and said motor drive shaft share a common geometric axis.
4. The system of claim 3 , wherein said accelerometer is in communication with one of a group consisting of said gyro and said motor drive shaft.
5. The system of claim 4 , wherein said accelerometer is disposed to move in a plane relative to said geometric axis.
6. The system of claim 1 , wherein said controller has memory storage.
7. An imbalance calibration apparatus, comprising
a centrifuge;
a centrifuge rotor mounted within said centrifuge;
an accelerometer in communication with said rotor and acting as an imbalance detector;
a controller that automatically calibrates said imbalance detector and assigns limits to said imbalance detector; and
a gyro in communication with a motor drive shaft.
8. The apparatus of claim 7 , wherein said imbalance detector is connected to said controller.
9. The apparatus of claim 7 , wherein said rotor, said gyro and said motor drive shaft share a common geometric axis.
10. The apparatus of claim 9 , wherein said accelerometer is disposed to move in a plane relative to said geometric axis.
