Abstract: A storage container that includes a housing having a bottom surface, two side walls, a front wall, and a back wall that form an interior space in the housing. The storage container also includes a lid configured to enclose the interior space. The two side walls of the housing include a rim portion and the lid includes a rail portion configured to provide a non-destructive and deformable locking and unlocking engagement with the rim portion. The back wall of the housing includes a first segment and a second segment, the second segment being separated a distance longitudinally from the first segment and connected to the first segment by a secondary bottom surface such that the second section of the interior space has a greater volume than the first section of the interior space.

Abstract: A torque sensing arrangement has a set of strain sensors, such as strain gauges, mounted to an adapter that can be mounted to a chain ring of the crank set of a bicycle wheel. The adapter may have an annular body that can be used to retrofit the original crank set of a bicycle to have torque sensing components without having to replace the chain rings or the crank arm of the crank set. Together with angular velocity measurements, the measurements of the strain sensors may be used to calculate the amount of work or power exerted by the cyclist to propel the bicycle.
