Method and apparatus for measuring power output and for measuring tension and vibrational frequency of a elongate flexible member |
摘要 |
The invention broadly provides a method and apparatus for measuring the power output of one powering a vehicle or other system driven by the elongate flexible member such as chain. In a preferred embodiment described, the vehicle is a bicycle. The method of the invention comprises measuring the speed and tension of the drive chain and calculating the power output therefrom. The apparatus of the invention includes a chain speed sensor, a chain tension sensor, and electronic processing means to calculate and display the power output based upon the chain measurements. <IMAGE> |
