title: A versatile SAMI--a self contained digital heart beat counter.
abstract: The existing SAMI's (Socially acceptable monitoring instruments) as used for monitoring the variations in physiological parameters were considered to have certain drawbacks, such as trigger level adjustments and the need for frequent contact with the clinician/investigator. In the present system these drawbacks have been overcome by incorporating an automatic gain control into the circuitry and by using CMOS devices.
