Abstract: An infinity brush has a flaccid belt configured to define a lemniscate. A plurality of work-contacting segments protrude from and are carried by the flaccid belt. A mechanical drive rotates the flaccid belt. Various embodiments of the flaccid belt include a single lemniscate, a plurality of lemniscates, and various simulated lemniscates. In one embodiment, the infinity brush bristle includes non-cylindrical brush bristles with a longitudinal shaft having at least one diameter transition, while other bristles comprise beads of various oval, circular, and cylindrical geometries.

Abstract: A pedal having a pedal shaft having first and second oppositely disposed ends, and an axis extending through the first end and the second end, the first end being connectable to a bicycle crank; a pedal housing rotatably mounted to said shaft about the axis of said shaft; a pedal frame pivotally mounted on said housing along a longitudinal axis substantially perpendicular to the axis of said shaft; and adjustable pivot stops for regulating the degrees of longitudinal pivoting of said pedal frame relative to the housing. The pedal can be referred to as a rocking pedal since it can provide an unobstructed or a cushion dampened rocking motion on a heel to toe axis.
