Abstract
The present invention is directed to an ambient temperature recalibration subsystem for a recalibration system that recalibrates a tympanic thermometer. In particular, the present invention relates to a computer-related invention comprising a computer that is in communication with a tympanic thermometer which includes an ambient sensing subsystem for sensing the surrounding ambient temperature experienced by the tympanic thermometer. The ambient temperature recalibration subsystem makes several threshold determinations before recalibration of the tympanic thermometer is allowed to proceed. The computer first instructs the thermometer to take a plurality of ambient temperature readings for determining whether the current ambient temperature experienced by the thermometer is stable. Once the temperature stability of the tympanic thermometer is determined, the computer determines whether the ambient sensing subsystem is providing an accurate ambient temperature reading by cross referencing one ambient sensor against another in the ambient sensing subsystem. An average ambient temperature is then determined from the plurality of readings previously taken which is then corrected using a scaling factor. If the corrected ambient temperature falls within a predetermined range of ambient temperatures, the computer permits the recalibration procedure to proceed.
