Process and apparatus for measuring vibrations and particularly nervous tremors of living organisms

Abstract From the Canadian patent

A process for measuring vibrations, especially nervous trembling in living organisms and a device for implementing said process. The device consists of a sensor (1) which converts the vibrations into an electric signal processed by an electronic circuit (2) making it possible to either display the result (3) or to transmit said result to other apparatus (recording devices computer, etc.). The different elements sensor (1), electronic circuit (2) and display (3) may or may not be all contained within the same housing (4). Said process and device serve essentially for measuring the degree of irritability (stress) for use by the general public for medical checks on patients under supervision …
