Magneto Cyclist Power Sensor
First Claim
1. As stated in the introduction, I claim to be the original inventor of a bicycle front derailleur mounted sensor with the intended use for incorporation into a system that determines the power delivered(through crank foot pedals) by the cyclist to propel his/her bike:

Abstract
This device is a sensor whose output can be used for providing the cyclist with a display of the power he/she is delivering to the wheels of the bicycle while he/she is riding. It can also be used to determine bike gear selection and bike ground speed. It is a sensor composed of magnet(s) and inductor(s) which attaches to a bikes front derailleur. Attaching the magnets and inductors to the derailleur causes them to move with the chain as the chain moves from gear to gear (also called sprocket) on the bike front gear assembly. Power is computed using a the vibrations of the bike and chain thats measured by the sensors and computed by a small signal processing chip.

-
2. This device is the first front derailleur mounted device that can be used to determine the sprocket selection on the bike and bike ground speed.
-
3. This system is unique in its design due to the integration of the user'"'"'s smartphone geographic, bike brand and model data, (through the phones internet access), with sensor data, for calibration of power calculations.
-
4. This system is the first to utilize in its design the time-varying bike chain vibration (measured signal by the faraday sensors) caused by the wheels rolling over the rough road surface to determine the tension in the bike chain.
