Abstract: A method and apparatus for simulating lung sounds in real time in an integrated patient simulator uses a manikin having an associated simulated lung comprising at least one bellows and at least one sensor for sensing the position of the bellows. Based on a physiological state of the patient simulator, a audible lung sound is directed through a plurality of sound output devices located at different locations on the manikin. The lung sound corresponds to an appropriate physiological sound at that particular location on the manikin and is synchronized with the position of the bellows. Synchronization occurs by continuously determining a volume of the bellows to determine a respiratory phase and a transition in the respiratory phase. The respiratory phase is determined by calculating a first derivative of the bellows volume over time and the transition in the respiratory phase is determined by calculating a second derivative of the bellows volume over time.

Abstract: An apparatus and method of simulating breathing sounds in real time involves the use of a manikin having a lung bellows. A sensor associated with the lung bellows is used to continuously determine the volume such that, using standard mathematical procedures based on the time and volume determined, a first derivative of the bellows volume over time can be calculated to determine the phase of the respiratory cycle (e.g. inhalation or exhalation). In addition, by calculating a second derivative of the bellows volume over time, a transition in phase of the respiratory cycle can be determined. Based upon the first and second derivatives of the bellows volume over time, a sound is output through an output device, such as a speaker, located proximate the mouth of the manikin. The outputted sounds are pre-recorded audible sounds of breathing corresponding to appropriate physiological sounds.

Abstract: A doll playset includes a padded cloth pouch having an interior within which a small doll heartbeat and kick simulating unit are received and supported. A pair of shoulder straps are secured to the pouch to facilitate the wearing of the pouch on the front abdominal area of a child user. The heartbeat and kick simulator includes a motor driven mechanism which produces undulating motion of a pair of kick simulating buttons supported upon the front surface of the simulator. A triangular cam is coupled to the undulating mechanism to provide flexing of an elongated resilient sounder resulting in heartbeat-like sounds when the unit is activated. A push button is supported upon the front surface of the simulator and may be depressed to operate the unit from the exterior of the cloth pouch.

Abstract: The invention relates to a doll equipped with a voice or sub-assembly supplied by an electric battery and adapted to emit sounds such as those accompanying the tears of a baby. This doll comprises in addition an infra-red radiation detector incorporaed close to one of the cheeks of the doll so as to be sensitive to the heat radiated by a child placed in the immediate proximity of this cheek. This detector is associated with exploitation means so that any emission of sounds by the doll is neutralized as soon as the heat power received by the detector exceeds a predetermined threshold.
