US 7,350,973 B2 · Color changing thermometer

Abstract

The invention includes a thermometer with a backlight and a method for lighting the backlight. The thermometer has temperature sensing tip, a processor taking temperature readings and determining a sensed temperature reading of the living being from the temperature sensing tip. The thermometer also includes a display and a backlight for lighting the display. The backlight is activated upon a command from the processor and the processor determines whether a decrease in the temperature readings exceeds or is equal to a predetermined threshold in order to activate the backlight. The method embodiment can includes the steps of using the processor to monitor a temperature change indicated by a temperature sensing element. The processor then detects a temperature decrease and activates a first color light emitting element to backlight a display if the temperature decrease exceeds or equals a predetermined threshold.

Dependent claims

A thermometer for use with a living being, comprising:

a temperature sensor;
a processor determining a temperature of the living being based on the temperature sensor;
a memory storing:
information corresponding to a first range of temperatures, the first range indicating a normal temperature;
and
information corresponding to a second range of temperatures, the second range indicating a fever condition;
a display including a first color light and a second color light for creating light of a first color and a second color;
and
a common housing, said temperature sensor, said processor, said memory, and said display being provided within said common housing;
wherein the processor accesses the memory and compares the temperature to the temperature range information stored in the memory and illuminates one of the first and the second color light based on the temperature.
