Abstract:
1. A treadmill comprising: a deck including a treadbelt rotatably attached thereto, an incline controller coupled to said deck, to selectively adjust said deck to different inclinations, a motor coupled to drive and to rotate said treadbelt relative to said deck, a microprocessor unit, a driver coupled to said microprocessor unit and said motor, to control and actuate said motor to adjust said treadbelt to different driving speeds, a loading detector coupled to said microprocessor unit and coupled to said driver and said motor, to detect a current loading applied to said treadbelt by a user traversing thereon, and to transmit the current loading to said microprocessor unit, said driver actuating said motor to increase the driving speed of said treadbelt when detected current loading applied to said treadbelt is greater than a predetermined average current loading applied to said treadbelt, and said driver actuating said motor to decrease the driving speed of said treadbelt when detected current loading applied to said treadbelt is lower than the predetermined average current loading applied to said treadbelt, and a sensor coupled to said microprocessor unit, to detect rotational speed of said treadbelt, and to transmit the driving speed of said treadbelt to said microprocessor unit, said microprocessor unit calculating the rotational speed of said treadbelt obtained from said sensor to obtain a predetermined average speed of said treadbelt, said driver actuating said motor to increase the driving speed of said treadbelt when detected driving speed of said treadbelt is greater than the predetermined average speed of said treadbelt, and said driver actuating said motor to decrease the driving speed of said treadbelt when detected driving speed of said treadbelt is slower than the predetermined average speed of said treadbelt.
