    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.

    摘要: The invention detects variation in the speed of the bicycle's drive chain using a sensor. Variations in chain speed are measured, with the resulting numbers displayed to be visible to the cyclist in real-time and/or saved for later downloading and viewing via computer. Metrics that can be calculated using variations in chain speed include: a smoothness index, which indicates how evenly the cyclist is applying force/power; chain speed variation to show the contribution of each leg to the overall force/power delivered; pedaling cadence; and a calculation of gear ratios. Some of these metrics can use inputs from additional sensors, such as a cadence sensor that is tripped by each revolution of the bicycle's crank arm, and wheel speed or GPS sensor for measuring the bicycle's speed.
