Abstract: An ergonomic pedaling apparatus for travel in water, enabling a user to practice swimming skills, comprising: an ergonomic supporting body for supporting the upper part of the user's body when frontally mounted over the body, where the body includes a curved triangular structure having three vertices constructed by three connected chassis members; three floatation units each connected to a separate vertex of the body; and a pedaling assembly comprising two scooped pedals enabling the user to progress in water by hand pedaling the pedals. The floatation units include: a first and a second back floatation units each comprising a float, where the floatability of the back floatation units is substantially equal and a third front floatation unit comprising two float parts vertically positioned one on top of the other. The floatability of the combined floats of the third floatation unit may be substantially equal to the floatability of each of the back floatation units.

Abstract: Presented herein is a system for transmitting sounds to an in-utero infant, that is worn by a pregnant woman, said system comprising a flexible carrier with two arms and adapted to accommodate the continuously changing shape of the abdomen of a pregnant woman; an array of speakers disposed on the arms of the carrier and substantially surrounding the in-utero infant with the sounds emitted from said speakers; an amplifier operatively associated with the array of speakers that enables tailoring the frequencies and tonal qualities of the sounds emitted from the array of speakers to levels suitable for an in-utero infant; and an audio device, operatively connected to the array of speakers and the amplifier, that provides a source from which sounds are played back.
