Abstract: A jewelry ring designed to be worn on the finger of a hand, having rotating halves that when rotated against one another cause the legs of a Horse or other figure attached to the outward face to move in a naturally articulate manner or run. The rings assembly consists of an inner and outer cylinder that contain one or more inner gears or friction driven cylinders which are positioned perpendicular relative to the center axis of the rotating cylinders and are held in place by the two cylinders. When the cylinders of the ring are rotated in opposing directions the cylinders that are positioned perpendicular to the center axis rotate. The rotational movement of the cylinders that are positioned perpendicular to the center axes cause the leg elements, consisting of upper and lower sections, connected to the cylinder and the Horse or other figure by rotational joints, to move in a fashion designed to mimic the natural leg movement of the horse or other figure on the ring or to appear to run.

Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for generating contextually relevant transcripts of voice recordings based on social networking data. For instance, the disclosed systems receive a voice recording from a user corresponding to a message thread including the user and one or more co-users. The disclosed systems analyze acoustic features of the voice recording to generate transcription-text probabilities. The disclosed systems generate term weights for terms corresponding to objects associated with the user within a social networking system by analyzing user social networking data. Using the contextually aware term weights, the disclosed systems adjust the transcription-text probabilities. Based on the adjusted transcription-text probabilities, the disclosed systems generate a transcript of the voice recording for display within the message thread.
