Abstract:
A method of controlling the energy to a radiant heater for supplying heat to an infant contained in an infant apparatus, said method comprising the steps of:a. measuring the skin temperature of an infant in the infant apparatus, b. inputting a set temperature desired for the infant, c. generating an error signal indicative of the difference between the input set temperature and the skin temperature of an infant to obtain a patient temperature gradient (PTG), d. providing a source of a first pouncer level to the radiant heater, and e. making an incremental adjustment to the first power level to the radiant heater to provide a second power level to the radiant heater by adding or subtracting to the first power level an incremental level of power that is determined by the magnitude and sign of the PTG.
