Abstract: A musical hoop toy may be provided with a hoop structure, a sensing mechanism coupled to the hoop structure and being disposed on an interior side of the hoop structure such that, when the hoop structure is spun around a person's waist, the sensing mechanism will be periodically activated by a portion of the person's waist, an audio speaker coupled to the hoop structure, and a controller operatively coupled to the sensing mechanism and the audio speaker. The controller may include a processor, a memory, and a computer program stored in the memory. The computer program may have a computer program portion that causes a music sequence to be generated and a computer program portion that causes an audio sound effect to be generated in response to each activation of the sensing mechanism.

Abstract: A two-way ratchet mechanism operated by a plunger that moves a pawl housing in one of two directions. The ratchet mechanisms are preferably used in a children's game to simultaneously gather game pieces in receptacles.
