Patent US 5,503,161

In a universal instrument for medical care a biocomputer is connected directly to the patient and uses sound and chemical spectrum analyzers to generate electronic signatures indicative of health conditions. The sound spectrum analyzer is an artificial cochlea that emulates a large number of tuned filters that operate in parallel and in real time. The chemical spectrum analyzer is a modified version of the well-known mass spectrometer. "Encyclopedic" knowledge and other computer aids are also included.
