Abstract: A personal recording page and document marker is provided by an audio-electronic module having a housing. A spring clip on the housing is adopted to attach the module to the cover of a book, report, or document. The module contains a recording/playback unit connected to a microphone/speaker exposed on a face of the housing. The recording/playback unit is activated by record and play buttons recessed in a face of the housing which operate switches connected to the recording and playback unit. A battery pack or compartment holds batteries which power the recording/playback unit.

Abstract: An electronic toy which enunciates words or phrases corresponding to sentence parts and a complete sentence by enunciating sounds corresponding to words of phrases selected from a plurality of addresses of a first memory representing audio data corresponding to such words or phrases arranged in each of a plurality of categories. The selected words or phrases correspond to different parts of speech, such as subjects, verbs, adjectives, direct objects and prepositional phrases. The selections are assembled in the second memory and enunciated. The toy may resemble a book in appearance and has printed lettering and color graphics corresponding to the words or phrases.

Abstract: A hobby horse includes a neck and head portion secured to the user's waist by a belt attachment. A rein switch is supported within the head interior and is coupled to each end of a closed rein set and is responsive to pulling action upon the reins. A motion sensing switch is supported within the head portion of the hobby horse and responds to motion and changes of motion of the child user and hobby horse. A pair of pressure sensitive switches are disposed proximate the forehead and mouth portions of the hobby horse and respond to simulated feeding and petting actions on the part of the user. A sound producing circuit includes a battery power system, a speaker and a sound sensitizing circuit operatively coupled to the range switch, the motion switch, the forehead switch, and the mouth switch to provide a plurality of sound outputs responsive to play activities sensed by the switches. The rein sensing switch is resistant to overstressing by the child user in pulling upon the reins.

Abstract: Computer toy to demonstrate logical relationships, e.g.

Abstract: Vibration triggered game device having a housing with a vibration sensitive reference base to generate vibrations in response to a manually applied vibratory stimulus during game play, and a circuit to sense the level of those vibrations relative to a preselective, e.g. adjustable, threshold value, and including an indicator, e.g. an audible signal emitter, triggered when that level exceeds the threshold value, to indicate the achieving of an event in the game. The circuit may include a piezo transducer to detect the vibrations and to emit the signal. The housing may be a game board provided with play elements depositable on, movable along, and/or removable from, the reference base, or the housing may be an object graspable during play, with all such manual actions being effectable at a vibration level above or below the threshold value depending upon player skill and dexterity.

Abstract: Balancing board device formed of a roller, a treadle board normally resting on the roller and a connector releasably interconnecting the board and roller, the connector including a first part on the board and a second part on the roller, the parts being substantially rigid and inflexible and normally arranged in coactive connection at a location completely within the roller outline for maintaining the roller substantially perpendicular to the longitudinal axis of the board and permitting limited relative longitudinal movement between the board and roller and rocking movement of the board on the roller while preventing separation of the roller from the board, and a release mechanism permitting disconnection of the parts for separation of the roller from the board.
