Patent attributes
A heartbeat or pulse generator device is provided separately for use in or in combination with a comfort product such as a plush toy. The heartbeat generator device includes an automatic control system that provides for controlled operation of the heartbeat generator while compensating for natural movements during use. The heartbeat generator device contains a pulse generator to create the motion necessary to cause the heart to “beat” twice early in a beat interval. The heartbeat generator device to increase battery longevity by allowing the generator device to selectively shut off when it senses that the animal or other user is no longer interacting with the product. As the animal interacts, the emulated heartbeat continues. When the animal stops interacting for a period of time, the heartbeat will stop, and battery life is preserved. The heart will restart when motion is detected once again. Further, the improved device contains a sensor and control system that can sense physical movement of the heartbeat generator device while at the same time compensating for the physical movement it is itself creating with the motor to emulate a heartbeat.
