Abstract
A power meter for cycling is capable of measuring a positional and/or alignment change of a first measurement location on a rigid component of a human-powered vehicle relative to a second measurement location. Power output by the cyclist during cycling is then calculated based upon the measured positional and/or alignment change. The positional and/or alignment change may be measured using, e.g., a magnet/magnetic-field sensor pair or by a light source/light sensor pair.
Claims20
A power meter for cycling, comprising:
- a first free-standing cantilever disposed at or on a first measurement location of a rigid component of a bicycle in a positionally fixed manner or connected in a positionally fixed manner to the first measurement location such that the first cantilever defines at least one first translocated measurement point that is configured to undergo the same positional change relative to a second measurement location of the rigid component as the first measurement location, the second measurement location being spaced apart from the first measurement location, and
- a measuring sensor system disposed at or on the first translocated measurement point and either at or on the second measurement location or at or on a second translocated measurement point that is configured to undergo the same positional change relative to the second measurement location of the rigid component as the second measurement location, the measuring sensor system being configured to detect a positional change of the first measurement location relative to the second measurement location resulting from a predetermined deformation of the rigid component.
A power meter for cycling, comprising:
- a light source disposed at or on a first measurement location of a rigid component that undergoes deformation during cycling, the light source being configured to radiate light toward a second measurement location of the rigid component,
- either (i) a reflective surface disposed at or on the second measurement location and a light sensor disposed at or on the first measurement location, or (ii) a light sensor disposed at or on the second measurement location, and
- a processing unit configured to determine a positional change of the first measurement location relative to the second measurement location based upon changes in a signal output by the light sensor as a result of deformation of the rigid component.
