Latest Patents

One of his latest patents is a method and apparatus for calibration and controlling multiple heaters. This innovative system utilizes a microcomputer and a multiplexer to calibrate and control multiple heaters. The heaters are sequentially sampled, and their resistance is calculated from voltage and current measurements. The operator inputs a temperature for the calculated resistance to establish a calibrated resistance value. During operation, the computer energizes and samples each heater to calculate its resistance. The calculated resistance is then divided by the calibrated resistance to determine a resistance ratio. A look-up table is stored in the computer, containing resistance ratios for corresponding temperatures. The computer compares the calculated ratio to that of the look-up table to determine actual heater temperatures. Based on these temperatures, the computer controls the energization of the heaters until the set points are achieved. This system can utilize negative temperature coefficient and positive temperature coefficient transistors and semiconductors.
