Abstract
A power measurement device, which may be mounted to an inside area of a crank arm, includes processing circuitry within a housing. The processing circuitry is coupled with strain gauges mounted on the crank arm, and produces a power value that is wireless transmitted to a separate display that may receive and display power measurements. The housing may include a mounted portion and a cantilever portion where the mounted portion houses the processing circuitry and the cantilever portion houses batteries supply energy for the processing circuitry and other features.
Claims15
A power measurement assembly comprising:
- a crank arm having a first end and a second opposite end, the crank arm including a pedal aperture at the first end, the crank arm comprising a wall on a first side of the crank arm, the wall having an outer surface;
- at least two strain gauges mounted on the outer surface of the wall on the first side of the crank arm and between the pedal aperture and the second end;
- and
- a housing affixed entirely on the outer surface of the wall on the first side of the crank arm and disposed entirely at a location between the pedal aperture and the second end, the housing covering the at least two strain gauges;
- and
- a circuit board positioned within the housing.
A power measurement assembly comprising:
- a crank arm having a first end and a second opposite end, the first end including a pedal aperture, the crank arm comprising a first sidewall on a first side of the crank arm and a second sidewall on a second opposite side of the crank arm, the pedal aperture supporting a pedal extending from the second sidewall on the second opposite side of the crank arm;
- at least two strain gauges mounted on the first sidewall and between the pedal aperture and the second end;
- and
- a housing mounted entirely on the first sidewall and positioned entirely between the pedal aperture and the second end of the crank arm, the housing enclosing the at least two strain gauges;
- and
- a circuit board positioned within the housing.
