  • Publication number: 20170259880
    Abstract: A crankset for a bicycle comprising a shaft rotationally engaged with a bicycle frame, the shaft having a radially extending flange disposed toward one end, a first crank arm and a second crank arm, and each connected to an opposing end of the shaft and being approximately 180 degrees out of phase with each other, a first sprocket keyed to the shaft, the first sprocket having a toothed belt engaging surface, and a spacer member disposed between the first sprocket and the flange for adjusting a first sprocket position.

  • Patent number: 6934641
    Abstract: In order to determine movements of two subjects, two or more signals of different phase are obtained which depend on the movement, and processed by locating constellation status of the signals in at least one co-ordinate axis system, it must have at least six separate segments rotationally displaced. Where there are two or more co-ordinate axis systems, each must have an axis radiating from an origin. The change in the constellation states is monitored using at least two processed data samples obtained by sampling the signals at a suitable clock rate. It is possible to derive a prediction of values of the signal and filter the signals in dependence on the prediction. The second co-ordinate axis system may be rotatable relative to the first co-ordinate axis system enabling the provision of a movable region of uncertainty.

  • Patent number: 6837390
    Abstract: A plastic container having a sidewall extending between a shoulder portion and a bottom portion. The sidewall has a substantially oval shape in cross-section and includes a pair of opposing columns and a pair of opposing panels. The columns are located at opposing ends of the oval shape and the panels are located at opposing sides of the oval shape. This configuration allows for reduced as-packaged vacuum pressures when the container is used in hot-fill applications.
