Abstract: A prenatal listening device includes first and second handheld units. The first handheld unit includes a cup-shaped body that defines an acoustic cavity. The first handheld unit further includes a microphone mounted to the body in the acoustic cavity to capture fetal sounds collected by the acoustic cavity. The second handheld unit is spaced from and communicatively coupled to the first handheld unit. The second handheld unit includes a controller to process signals from the microphone indicative of the captured fetal sounds, a housing to enclose the controller, and an audio output to reproduce the captured fetal sounds.

Abstract: A children's development device has a carrier coupled to a juvenile product and elevated above a support surface. The carrier defines an x-y-z axis system including a generally vertical z-axis, a generally horizontal x-axis and a generally horizontal y-axis oriented normal or perpendicular to the x-axis. A child seat is coupled to the carrier and positionable such that feet of an occupant of the seat can contact a launching surface.
