Abstract

A method, computer program product, and image branding system brand an image on a product. The system includes an image controller to determine current values for application to one or more thermoelectric devices. The image controller also determines a current range within which to select the current values based on a material composition of the product. The system also includes an image branding device including the thermoelectric devices. Each of the thermoelectric devices have a corresponding contact surface representing a single pixel. The contact surface of each of the one or more thermoelectric devices is heated based on the respective current value applied.

First claim

What is claimed is:

1. An image branding system to brand an image on a product, the system comprising:
an image controller configured to determine current values for application to one or more thermoelectric devices, wherein the image controller is further configured to determine a current range within which to select the current values based on a material composition of the product; and
an image branding device comprising the thermoelectric devices, each of the thermoelectric devices having a corresponding contact surface representing a single pixel, wherein the contact surface of each of the one or more thermoelectric devices is heated based on the respective current value applied.

2. The system according to claim 1 , wherein each of the one or more thermoelectric devices includes an n-type thermoelectric element electrically coupled to a p-type thermoelectric element.

3. The system of claim 1 , wherein each of the one or more thermoelectric devices comprises two or more pairs of thermoelectric elements, each pair of the thermoelectric elements including an n-type thermoelectric element electrically coupled to a p-type thermoelectric element.

4. The system of claim 3 , wherein the contact surface corresponding to each of the one or more thermoelectric devices is coupled to an end of the n-type thermoelectric element and the p-type thermoelectric element.

5. The system of claim 3 , wherein each of the thermoelectric elements is electrically coupled to an electrode.

6. The system according to claim 1 , wherein the image controller is further configured to pixilate the image.

7. The system according to claim 6 , wherein the image controller is configured to pixilate the image based on a number of the contact surfaces of the image branding device and a number of increments of current values available within the current range.

8. The system according to claim 1 , wherein the image controller is further configured to determine a number of searing stages, wherein the respective current value is applied to a subset of the one or more thermoelectric devices in each of the searing stages.

9. A computer-implemented method of branding an image on a product, the method comprising:
obtaining, using an image controller, the image and information regarding the product;
determining, using the image controller, a current range based on a material composition of the product;
determining, using the image controller, current values within the current range for application to one or more thermoelectric devices of an image branding device; and
branding the image on the product based on applying the current values to the one or more thermoelectric devices.

10. The computer-implemented method according to claim 9 , further comprising obtaining a grayscale image based on the image being a color image.

11. The computer-implemented method according to claim 9 , further comprising pixilating the image.

12. The computer-implemented method according to claim 11 , wherein the pixilating the image is based on a pixel resolution of the image branding device and the current range.

13. The computer-implemented method according to claim 9 , further comprising determining a number of searing stages for the image branding device, wherein the respective current value is applied to a subset of the one or more thermoelectric devices in each of the searing stages.

14. The computer-implemented method according to claim 9 , further comprising providing instructing from the image controller to the image branding device to brand the image on the product.

15. A computer program product for branding an image on a product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to perform a method comprising:
obtaining the image and information regarding the product;
determining a current range based on a material composition of the product; and
determining current values within the current range for application to one or more thermoelectric devices of an image branding device, wherein the image is branded on the product based on the current values determined for application to the one or more thermoelectric devices.

16. The computer program product according to claim 15 , further comprising obtaining a grayscale image based on the image being a color image.

17. The computer program product according to claim 15 , further comprising pixilating the image.

18. The computer program product according to claim 17 , wherein the pixilating the image is based on a pixel resolution of the image branding device and the current range.

19. The computer program product according to claim 15 , further comprising determining a number of searing stages for the image branding device, wherein the respective current value is applied to a subset of the one or more thermoelectric devices in each of the searing stages.

20. The computer program product according to claim 15 , further comprising providing instructions to the image branding device to brand the image on the product.
