A CRANK MEASUREMENT SYSTEM WITH IMPROVED STRAIN GAUGE INSTALLATION

A crank power measurement system measures one or more of force, torque, power, and velocity of the crank, and includes a crank, two or more strain gauges located on a surface of the crank, and electronics for receiving strain data from the two or more strain gauges and determining at least one or mo...

Beschreibung
Zusammenfassung:	A crank power measurement system measures one or more of force, torque, power, and velocity of the crank, and includes a crank, two or more strain gauges located on a surface of the crank, and electronics for receiving strain data from the two or more strain gauges and determining at least one or more of bend-strain, shear-strain, and axial strain. A bicycle crank mounted power generator generates power when the bicycle is being ridden by a user, and includes a base ring, with a plurality of magnets, attached to a frame of the bicycle and circling a bottom bracket attached to a crank, a coil system attached to the crank adjacent to the plurality of magnets to generate an output at leads of the coil, and electronics configured to manipulate the output to power an electronic device and/or store the output in a power supply.
