Claim of US Patent No. 10,251,213

1. A method of heating a conductive ribbon, the method comprising:clamping a conductive ribbon to a surface of a non-conductive base using conducting pads such that a selected section of the conductive ribbon is bound by the conducting pads;
applying a voltage signal from a variable power supply across the conducting pads to cause the selected section of the conductive ribbon to heat up;
taking a measurement of at least one electrical property associated with the conductive ribbon in response to the voltage signal applied across the conducting pads;
placing a biological sample on the conductive ribbon between the conductive pads applying a voltage signal from the variable power supply across the conducting pads to cause the selected section of the conductive ribbon to heat up;
computing, based on the measurement and Ohm's law, a correction for the voltage signal applied across the conducting pads to achieve a desired temperature of the selected section of the conductive ribbon, wherein the desired temperature is selected for processing the biological sample on the conductive ribbon and the correction accounts for a variance in the selected section of the conductive ribbon;
adjusting the applied voltage signal based upon the computed correction to regulate the selected section of the conductive ribbon at the desired temperature; and
holding the selected section of the conductive ribbon at the desired temperature for a predetermined time.
