Abstract

Embodiments relate generally to systems and methods for determining the temperature of an object or surface near a user, such as a firefighter, in potentially dangerous conditions. A temperature sensor configured to be attached to a personal protection equipment may comprise a standoff temperature sensor element configured to detect the temperature of a nearby object or surface; a microcontroller configured to receive sensor data from the standoff temperature sensor element and determine the sensed temperature; an indicator configured to be activated by the microcontroller when the sensed temperature is higher than a predefined threshold; and an attachment element configured to attach the sensor to a personal protection equipment worn by a user.

Claims (52)

1. A temperature sensor configured to be attached to an item of personal protection equipment, the temperature sensor comprising:

a standoff temperature sensor element configured to sense the temperature of a nearby object or surface, wherein the standoff temperature sensor element includes a thermopile;

a microcontroller configured to receive sensor data from the standoff temperature sensor element and determine the sensed temperature;

an indicator configured to be activated by the microcontroller when the sensed temperature is higher than a predefined threshold;

a housing, wherein the standoff temperature sensor element, the microcontroller, and the indicator are disposed within the housing, and wherein the housing comprises an insulation to insulate the standoff temperature sensor element, the microcontroller, and the indicator from heat; and

an attachment element,

wherein the attachment element is configured to securely but removably attach to the personal protection equipment,

wherein the attachment element comprises a clip,

wherein the personal protection equipment comprises a slot, a strap, or a pocket configured to receive the clip, and

wherein the temperature sensor is configured to removably attach to the personal protection equipment via the attachment element.

2. The temperature sensor of claim 1 , wherein at least a portion of the standoff temperature sensor element is exposed to an external environment by an opening in the housing.

3. The temperature sensor of claim 1 , further comprising a switch configured to allow a user to control the temperature sensor.

4. The temperature sensor of claim 1 , wherein the indicator comprises a vibrating motor.

5. The temperature sensor of claim 1 , wherein the indicator comprises an audible alert.

6. The temperature sensor of claim 1 , wherein the indicator comprises a visible alert.

7. The temperature sensor of claim 1 , wherein the personal protection equipment comprises a glove, and wherein the temperature sensor is attached to a back of a user's hand via the glove.

8. The temperature sensor of claim 1 , wherein the temperature sensor does not comprise a thermal imaging element.

9. A method for determining the temperature of an object or surface near a user, the method comprising:

removably attaching an attachment element to a personal protection equipment, wherein the attachment element comprises a clip, and wherein the personal protection equipment comprises a slot, a strap, or a pocket configured to receive the clip,

removably attaching a temperature sensor to the personal protection equipment via the attachment element,

wherein the temperature sensor comprises a housing,

wherein a standoff temperature sensor element, a microcontroller, and an indicator are disposed within the housing,

wherein the housing comprises an insulation to insulate the standoff temperature sensor element, the microcontroller, and the indicator from heat,

wherein the standoff temperature sensor element is in proximity to the object or surface,

and wherein the standoff temperature sensor element includes a thermopile;

receiving, by the microcontroller of the temperature sensor, sensed data from the standoff temperature sensor element;

determining a sensed temperature based on the received sensed data;

determining when the sensed temperature is higher than a predefined threshold; and

activating the indicator when the sensed temperature is higher than the predefined threshold.

10. The method of claim 9 , wherein activating the indicator comprises one or more of the following:

activating a vibrating motor to generate a vibration that is felt by the user;

activating an audible alert; and

activating a visible alert.

11. The method of claim 9 , further comprising exposing the standoff temperature sensor element to ambient temperature via an opening in the housing of the temperature sensor.

12. The method of claim 9 , further comprising determining a local temperature by the user without the user removing the personal protection equipment.

13. The method of claim 9 , wherein removably attaching the temperature sensor to the personal protection equipment via the attachment element comprises attaching the temperature sensor to the personal protection equipment worn by the user.

14. The method of claim 13 , wherein removably attaching the temperature sensor to the personal protection equipment comprises attaching the temperature sensor to a backside of a glove.

15. A personal protection equipment comprising:

a temperature sensor attached to the personal protection equipment via an attachment element, the temperature sensor comprising:

a standoff temperature sensor element to sense the temperature of a nearby object or surface, wherein the standoff temperature sensor element includes a thermopile;

a microcontroller configured to receive sensor data from the standoff temperature sensor element and determine the sensed temperature;

an indicator configured to be activated by the microcontroller when the sensed temperature is higher than a predefined threshold;

a housing, wherein the standoff temperature sensor element, the microcontroller, and the indicator are disposed within the housing and wherein the housing, comprises an insulation to insulate the standoff temperature sensor element, the microcontroller, and the indicator from heat; and

the attachment element,

wherein the attachment element is configured to securely but removably attach to the personal protection equipment, and

wherein the attachment element comprises a clip, and

the personal protection equipment further comprising a slot, a strap, or a pocket configured to receive the clip,

wherein the temperature sensor is configured to removably attach to the personal protection equipment via the attachment element.

16. The personal protection equipment of claim 15 , wherein at least a portion of the standoff temperature sensor element is exposed to an external environment by an opening in the housing.

17. The personal protection equipment of claim 15 , wherein the temperature sensor further comprises a switch configured to allow a user to control the temperature sensor.

18. The personal protection equipment of claim 15 , wherein the indicator comprises a vibrating motor.

19. The personal protection equipment of claim 15 , wherein the personal protection equipment comprises a glove, and wherein the temperature sensor is attached to a back of a user's hand via the glove.
