Abstract

An electronic thermometer capable of displaying a body temperature in a plurality of temperature units in an automatically selectable sequence, comprising means for measuring a body temperature which includes a temperature sensor, means for displaying the body temperature as measured by the measuring means, means for selecting one of the temperature units in which the body temperature is displayed by the display means, means for setting a measuring time period and control means associated with the means for selecting a temperature unit for causing the display means to display the body temperature in one of the temperature units during the measuring time period and in another of the temperature units after the measuring time period.

Claims

1. An electronic thermometer capable of displaying a body temperature in a plurality of temperature units in an automatically selectable sequence, comprising:

means for measuring a body temperature which includes a temperature sensor and a means for detecting the completion of each measurement;

means for displaying said body temperature as measured by said measuring means;

means for selecting one of said temperature units in which said body temperature is displayed by said display means;

means responsive to the completion of each measurement as detected by said detecting means for setting a measuring time period; and

,

control means associated with said means for selecting a temperature unit for causing said display means to display said body temperature in one of said temperature units during said measuring time period and in another of said temperature units after said measuring time period.

2. An electronic thermometer according to claim 1 wherein the temperature unit in which said body temperature is displayed within said measuring time period is the temperature unit selected by said means for selecting a temperature unit.

3. An electronic thermometer according to claim 1 wherein the temperature unit selected by said means for setting a measuring time period is Fahrenheit or Centigrade.

4. An electronic thermometer according to claim 1 wherein said measuring time period is a predetermined fixed time period.

5. An electronic thermometer according to claim 1 wherein said completion of each measurement corresponds to a time point when a predetermined subsequent time period elapses after the temperature of said temperature responsive element remains constant after a period in which it rises.

6. An electronic thermometer according to claim 1 wherein said control means causes said display means to flicker the display of the measured body temperature within said measuring time period.
