Abstract

A device for use in detecting metallic objects includes a processor and an electromagnetic radiation source in communication with the processor. The electromagnetic radiation source is configured to emit radiation to heat a metallic object. The device also includes a temperature sensor in communication with the processor. The temperature sensor is configured to detect heat emitted from the metallic object. The device also includes an alarm configured to notify an operator of the presence of the metallic object responsive to a determination by the processor that a temperature threshold has been exceeded.

Claims

1. A device for use in detecting metallic objects, the device comprising:

a processor;

an electromagnetic radiation source in communication with the processor, wherein the electromagnetic radiation source is configured to emit radiation to heat a metallic object;

a temperature sensor in communication with the processor, wherein the temperature sensor is configured to detect heat emitted from the metallic object; and

an alarm configured to notify an operator of the presence of the metallic object responsive to a determination by the processor that a temperature threshold has been exceeded.

2. The device of claim 1, further comprising a stationary housing that includes a detection area, wherein the temperature sensor is positioned within the detection area.

3. The device of claim 2, further comprising a movable platform onto which the temperature sensor is mounted, wherein the movable platform is configured to move relative to an individual positioned within the detection area.

4. The device of claim 1, wherein the metallic object is within a parcel or a piece of luggage.

5. The device of claim 1, wherein the processor is configured to determine the temperature threshold based at least in part on an ambient temperature of an environment in which the device is located.

6. The device of claim 5, wherein the temperature threshold is dynamic such that the temperature threshold changes as the ambient temperature changes.

7. The device of claim 1, wherein the processor is configured to determine the temperature threshold based at least in part on a body temperature of an individual being tested by the device.

8. The device of claim 1, wherein a magnitude of the electromagnetic radiation source is adjustable.

9. The device of claim 1, further comprising a housing in the form of a handheld wand, wherein the processor, temperature sensor, electromagnetic radiation source, and alarm are incorporated into the housing.

10. The device of claim 1, wherein the temperature sensor comprises a plurality of temperature sensors positioned in an array.

11. The device of claim 10, wherein the processor is configured to monitor the array of temperature sensors to detect movement on an other side of a wall relative to the device.

12. The device of claim 11, wherein the processor is configured to:

identify a first temperature detected by a first temperature sensor at a first time and at a second time; and

identify a second temperature detected by a second temperature sensor at the first time and at the second time.

13. The device of claim 12, wherein the processor is configured to compare the first temperature and the second temperature at each of the first time and the second time to determine whether movement has occurred.

14. The device of claim 1, wherein the temperature sensor is configured to determine both an ambient temperature and a temperature proximate to the metallic object.

15. The device of claim 14, wherein the processor is configured to:

determine a difference between the ambient temperature and the temperature proximate to the metallic object that results from use of the induction heat source;

compare the difference to the temperature threshold; and

trigger the alarm responsive to a determination that the difference exceeds the temperature threshold.

16. A method for detecting metallic objects, the method comprising:

emitting, by an electromagnetic radiation source of a detection device, radiation to heat a metallic object by way of induction;

detecting, by a temperature sensor of the detection device, heat emitted from the metallic object;

determining, by a processor of the detection device, whether the heat emitted from the metallic object exceeds a temperature threshold; and

triggering an alarm responsive to a determination that the temperature threshold is exceeded.

17. The method of claim 16, further comprising determining, by the processor, the temperature threshold based at least in part on an ambient temperature of an environment in which the detection device is located.

18. The method of claim 16, further comprising determining, by the processor, the temperature threshold based at least in part on a body temperature of an individual being scanned by the detection device.

19. The method of claim 16, further comprising:

identifying a first temperature detected by a first temperature sensor at a first time and at a second time;

identifying a second temperature detected by a second temperature sensor at the first time and at the second time; and

comparing the first temperature and the second temperature at each of the first time and the second time to determine whether movement of the metallic object has occurred.

20. The method of claim 16, wherein the temperature sensor is mounted on a movable platform, and further comprising moving the movable platform relative to an individual positioned in a detection area.
