Abstract

An instrument for recording individual body temperature data by means of an electrical temperature sensor to determine the ovulation time of humans or animals, has a data counter which is fed by temperature data pulses, and generates a mean value which is fed to an output of the data counter thus enabling the instrument to self-adjust for sensor drift and physiological changes. The instrument also has an electrical display, which is connected to the output, to display temperature data.

Claims

1. Method of processing data for determining the time of ovulation in an animal during each menstrual cycle, said method comprising the steps of:

a) periodically receiving a plurality of first data values during a current menstrual cycle, said first data values being related to a measured temperature of the animal at preselected first times during the current menstrual cycle;

b) comparing each said first data value to a stored offset temperature value of the animal from a previous menstrual cycle;

c) generating an output by calculating the difference between each said first data value and said stored offset temperature value at each preselected first time;

d) displaying said output;

e) summing together each said difference between each said first data value and said stored offset temperature value;

f) generating a second data value equal to the average of said differences between each said first data value and said stored offset temperature value at a preselected second time, said preselected second time being greater than said preselected first time;

g) generating a third data value equal to the difference between said second data value and a stored average temperature value from a previous menstrual cycle;

h) substituting said third data value for said stored offset temperature value; and

i) periodically repeating said steps a) through h), wherein said third data value becomes said stored offset temperature for a subsequent cycle of steps a) through h) during a subsequent menstrual cycle.
