Abstract

A calibration verification system 20 comprises a trainer 40 having a load generator, a variable load control system (hidden by the cover of the load generator) connected in electrical communication with the load generator, and an exercise trainer computer system 140 connected in communication with the variable load control system. In operation, the exercise trainer computer system 140 outputs commands to the variable load control system. These commands can, for example, instruct the variable load control system to energize the load generator at predetermined times and power levels in order to simulate changes in terrain. The calibration verification system 20 also allows the user to verify the calibration of the trainer 40 by implementing a user initiated process, which conducts a calibration verification test of the trainer and outputs the test data at the exercise trainer computer system 140.

Claims

1. A method for verifying the calibration of an exercise trainer, the trainer having a flywheel rotated through user input, and a load generator through which an outer portion of the flywheel rotates, the method comprising:

obtaining a user start command;

obtaining data indicative of flywheel rotational speed of the trainer;

applying a load generated by the load generator onto the outer portion of the flywheel as the outer portion of the flywheel rotates through the load generator;

obtaining signals indicative of flywheel rotation;

determining calibration test data for the current operation of the trainer from the obtained signals.

2. The method of claim 1, further comprising displaying the calibration test data for the current operation of the trainer.

3. The method of claim 1, wherein obtaining signals includes obtaining counts indicative of flywheel rotation.

4. The method of claim 3, wherein determining calibration test data for the current operation of the trainer includes measuring a period of time necessary to achieve a pre-selected count value.

5. The method of claim 1, wherein the signals are indicative of an estimated travel speed associated with flywheel assembly rotation.

6. The method of claim 5, wherein determining calibration test data for the current operation of the trainer includes calculating the total time elapsed from a first travel speed to a second travel speed.

7. In a system having an exercise trainer with a load generator and a flywheel, wherein the system has standard calibration data, a method for verifying the calibration of the exercise trainer, comprising:

applying a load generated by the load generator onto the outer portion of the flywheel as the outer portion of the flywheel rotates through the load generator;

obtaining signals indicative of flywheel rotational speed of the trainer;

obtaining a current calibration data for the trainer; and

determining whether the current calibration data substantially matches the standard calibration data.

8. The method of claim 7, wherein obtaining signals includes obtaining counts indicative of flywheel rotation.

9. The method of claim 8, wherein obtaining a current calibration data for the trainer includes measuring a period of time necessary to achieve a pre-selected count value.

10. The method of claim 7, wherein the signals are indicative of an estimated travel speed associated with flywheel rotation.

11. The method of claim 10, wherein obtaining a current calibration data for the trainer includes calculating the total time elapsed from a first travel speed to a second travel speed.

12. The method of claim 7, wherein the standard calibration data is generic to a class of trainers.

13. The method of claim 7, wherein the standard calibration data is specific to a particular user'"'"'s trainer.

14. The method of claim 7, wherein applying a load generated by the load generator includes

applying a constant current to the load generator for producing a magnetic field through which the outer portion of the flywheel is rotated.

15. The method of claim 7, wherein applying a load generated by the load generator includes

applying a constant voltage to the load generator for producing a magnetic field through which the outer portion of the flywheel is rotated.

16. The method of claim 7, wherein applying a load generated by the load generator includes:

applying a variable current to the load generator for producing a magnetic field through which the outer portion of the flywheel is rotated.
