Abstract

A method of updating a database listing ingredients of food products sold, where the database resides in a portable device used to scan food product labels to detect the presence of particular ingredients in food products, includes the steps of obtaining information regarding the ingredients of food products sold to consumers, updating a database that lists ingredients of food products, and transmitting the updated database to a desired number of portable devices used to scan product labels. A portable device for scanning a food product label includes a keypad, a display, a barcode scanner, a database listing ingredients of food products, a processor to compare the target food product ingredient to the database of ingredients, and an indicator to indicate whether or not the target food product ingredient is present, and when the database does not include the scanned product.

Claims

1. A method of updating a database listing ingredients of food products sold, the database residing in a portable device used to scan food product labels to detect the presence of particular ingredients in food products, comprising the steps of:

obtaining information regarding the ingredients of food products sold to consumers;

updating a database that lists ingredients of food products; and

transmitting the updated database to a desired number of portable devices used to scan food product labels to detect the presence of particular ingredients.

2. The method of claim 1, wherein the step of transmitting the database to a portable device includes replacing a read-only-memory chip of the portable device with a read-only-memory chip having the updated database.

3. The method of claim 1, wherein the step of transmitting the database to a portable device includes sending the database via the Internet.

4. The method of claim 1, wherein the step of transmitting the database to a portable device includes sending the database via a modem.

5. The method of claim 1, further including the step of repeating the steps of obtaining information regarding the ingredients of food products, creating an updated database, and transmitting the updated database on a scheduled basis.

6. The method of claim 5, wherein a provider that updates the database provides updated databases to users on a subscription basis.

7. A portable device for scanning a food product label to detect an ingredient of the food product comprising, in combination:

a keypad to enter a target food product ingredient a user is trying to detect;

a display;

a barcode scanner to scan a barcode of a food product;

a database listing ingredients of food products;

a processor to compare the target food product ingredient to the database of ingredients; and

an indicator to indicate when the target food product ingredient is present in a food product, when the target food product ingredient is not present in the food product, and when the database does not include the scanned food product.

8. The portable device of claim 7, wherein the indicator comprises three lights, a first of the lights being illuminated when an ingredient is present in a food product, a second of the lights being illuminated when the ingredient is not present in the food product, and a third of the lights being illuminated when the database does not include the scanned food product.

9. The portable device of claim 8, wherein the lights are LEDs.

10. The portable device of claim 7, further comprising a button to activate the barcode scanner.

11. The portable device of claim 7, wherein the display provides a user with a menu display from which the user can select the target food product ingredient via the keypad.

12. The portable device of claim 11, wherein the menu display includes a main menu and at least one sub-menu.

13. The portable device of claim 7, further comprising a read-only-memory chip that holds the database.

14. The portable device of claim 13, wherein the read-only-memory chip is configured to be replaceable by a read-only-memory chip having a revised database of food product ingredients.
