    摘要: The invention relates to an apparatus and method for extracting vibration data from a moving drive chain. In the preferred embodiment, the chain is that of a bicycle, or similar pedaled machine such as an indoor stationery bicycle, with two or more sensors placed on the chainstay of the bicycle to measure the vibrational frequency of the chain. Such vibration data can be used to determine the tension of the chain, and may also further compute the power transmitted by the chain, in conjunction with the measurement of chain speed. The invention provides a method and apparatus for conditioning and filtering the signals from the vibration sensors, as well as an arrangement for positioning the sensors on the bicycle.
