Abstract

At least one indicator light is located on the body or probe sections of a thermometer to indicate to the user that adjustments should be made to the timing or probe cover positioning of the thermometer. Additionally or alternatively the thermometer retains and displays information from previous uses, and in particular displays information pertaining to how long ago the last temperature measure was taken. Additionally, the thermometer may include additional buttons which can function to toggle the display to provide various types of information to the user, or toggle between thermometer usage modes, icon display, and LED color, among others. In another aspect, an internal body section with an access door provides access to a button allowing the user to toggle the interface of the thermometer, such as whether the temperature output is in degrees Fahrenheit or degrees Centigrade.

Claims

1. A thermometer comprising:

a case having a probe section and a body section;

a processor disposed within the case;

a temperature sensing element disposed within the probe section and coupled to the processor;

a display disposed in the body section and coupled to the processor;

a plurality of positioning sensors disposed in the probe section and configured to determine a position of a probe cover installable onto the probe section, the at least one first positioning sensor coupled to the processor;

an indicator disposed on the case to indicate misalignment of the probe cover; and

a memory coupled to the processor and comprising program code configured to;

process signals from the temperature sensing element and cause the display to display a corresponding temperature value; and

process signals from the plurality of positioning sensors to determine if the probe cover is properly aligned on the probe section and to control the indicator to indicate to a user a direction of misalignment of the probe cover.

2. The thermometer of claim 1 wherein the plurality of positioning sensors determines the position of the probe cover according to a plurality of quadrants of the probe section, the indicator includes a corresponding number of quadrants, and the program code causes the processor to control the indicator to indicate in which quadrant the direction of misalignment of the probe cover occurs.

3. The thermometer of claim 1 wherein the indicator comprises a plurality of light-emitting diodes (LEDs).

4. The thermometer of claim 1 wherein for at least a previous temperature measurement the memory stores a corresponding measurement time of the previous temperature measurement, and the processor controls the display to display the previous temperature measurement and how long ago the previous temperature measurement was taken according to the measurement time stored in the memory.

5. The thermometer of claim 1 wherein for at least a previous temperature measurement the memory stores a corresponding measurement time of the previous temperature measurement, and the processor controls the display to display the previous temperature measurement and a time corresponding to the measurement time stored in the memory.

6. The thermometer of claim 1 wherein the case further comprises an access door for covering a compartment, and a switch is disposed within the compartment to control whether a temperature displayed on the display is shown in degrees Fahrenheit or degrees Centigrade.

7. The thermometer of claim 1 wherein a user interface of the thermometer changes according to whether or not the plurality of positioning sensors detects whether or not a probe cover is disposed on the probe section.

8. The thermometer of claim 1 wherein the display further includes a plurality of icons to indicate which one of a plurality of age groups is selected, and the processor controls the display according to the selected age group.

9. A thermometer comprising:

a case having a probe section having a plurality of positioning sensors and a body section;

a processor disposed within the case;

a temperature sensing element disposed within the probe section and coupled to the processor;

a display disposed in the body section and coupled to the processor; and

a memory coupled to the processor and comprising program code configured to;

process signals from the temperature sensing element and determine a corresponding temperature value;

store in the memory a measurement time corresponding to the temperature value;

store in the memory the temperature value; and

control the display to display the temperature value and how long ago the temperature value was obtained according to the measurement time stored in the memory.

10. The thermometer of claim 9 further comprising:

the plurality of positioning sensors disposed in the probe section and configured to determine a position of a probe cover installable onto the probe section, the plurality of positioning sensors coupled to the processor; and

an indicator disposed on the case to indicate misalignment of the probe cover;

wherein the program code is further configured to process signals from the plurality of positioning sensor to determine if the probe cover is properly aligned on the probe section and to control the indicator to indicate to a user a direction of misalignment of the probe cover.

11. The thermometer of claim 10 wherein the plurality of positioning sensors determines the position of the probe cover according to a plurality of quadrants of the probe section, the indicator includes a corresponding number of quadrants, and the program code causes the processor to control the indicator to indicate in which quadrant the direction of misalignment of the probe cover occurs.

12. The thermometer of claim 11 wherein the indicator comprises a plurality of light-emitting diodes (LEDs).

13. The thermometer of claim 9 wherein the case further comprises an access door for covering a compartment, and a switch is disposed within the compartment to control whether a temperature displayed on the display is shown in degrees Fahrenheit or degrees Centigrade.

14. The thermometer of claim 9 wherein a user interface of the thermometer changes according to whether or not a probe cover is disposed on the probe section.

15. The thermometer of claim 9 wherein the display further includes a plurality of icons to indicate which one of a plurality of age groups is selected, and the processor controls the display according to the selected age group.
