Abstract

A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.

Claims

1. A portable, dual-use instrument for marking surfaces by a user, and for electro-optically collecting data selected by the user, for subsequent downloading, comprising:

a) a narrow, elongated housing extending along an axis between opposite end regions, and having a size and shape configured to be held by and among fingers of a single hand of the user during both marking and data collection;

b) a marking implement supported by the housing and having a marker at one of the end regions of the housing and facing a surface to be marked during marking; and

c) a data collector supported by the housing and having a light-transmissive window at another of the end regions of the housing and facing a bar code symbol during data collection, the data collector including a light source operative for directing a light beam through the window to the symbol for reflection therefrom, a light sensor having a field of view and operative for detecting light reflected off the symbol through the window and generating an electrical signal indicative of the detected light, a processor for processing the electrical signal into a processed signal, and a memory for storing the processed signal corresponding to the data selected by the user, and for storing user information uniquely identifying the user who selected the data, for subsequent downloading.

2. The instrument of claim 1, wherein the housing bounds an interior in which the data collector is accommodated, and wherein the housing has separable portions which, upon separation, enable access to the interior.

3. The instrument of claim 2, wherein the housing has an exterior clip for clipping the housing to a part of the user'"'"'s clothing.

4. The instrument of claim 2, wherein the marking implement includes a fluid cartridge having a nib, and a mechanism for retracting the nib within the housing, and for exposing the nib as the marker during marking.

5. The instrument of claim 1, wherein the data collector includes a scanner for scanning at least one of the light beam and the field of view.

6. The instrument of claim 5, wherein the data collector includes a manually actuatable trigger on the housing for initiating scanning.

7. The instrument of claim 1, wherein the window lies in a plane that is generally perpendicular to the axis.

8. The instrument of claim 1, wherein the window lies in a plane that is inclined at an angle to the axis.

9. The instrument of claim 1, wherein the user information includes a billing number for the user.

10. The instrument of claim 1, wherein the user information includes a billing address for the user.

11. A system for electro-optically collecting and downloading data, and for retrieving information based on the data, comprising:

a) a portable, dual-use instrument for marking surfaces by a user, and for electro-optically collecting data selected by the user, including

i) a narrow, elongated housing extending along an axis between opposite end regions, and having a size and shape configured to be held by and among fingers of a single hand of the user during both marking and data collection;

ii) a marking implement supported by the housing and having a marker at one of the end regions of the housing and facing a surface to be marked during marking; and

iii) a data collector supported by the housing and having a light-transmissive window at another of the end regions of the housing and facing a bar code symbol during data collection, the data collector including a light source operative for directing a light beam through the window to the symbol for reflection therefrom, a light sensor having a field of view and operative for detecting light reflected off the symbol through the window and generating an electrical signal indicative of the detected light, a processor for processing the electrical signal into a processed signal, and a memory for storing the processed signal corresponding to the data selected by the user, and for storing user information uniquely identifying the user who selected the data; and

b) a download port bounding a cavity having a size and shape configured to receive the other of the end regions of the housing during downloading of the processed signal and the user information stored in the memory of the data collector for developing a unique user profile.

12. The system of claim 11, wherein the housing bounds an interior in which the data collector is accommodated, and wherein the housing has separable portions which, upon separation, enable access to the interior.

13. The system of claim 12, wherein the housing has an exterior clip for clipping the housing to a part of the user'"'"'s clothing.

14. The system of claim 12, wherein the marking implement includes a fluid cartridge having a nib, and a mechanism for retracting the nib within the housing, and for exposing the nib as the marker during marking.

15. The system of claim 11, wherein the data collector includes a scanner for scanning at least one of the light beam and the field of view.

16. The system of claim 15, wherein the data collector includes a manually actuatable trigger on the housing for initiating scanning.

17. The system of claim 11, wherein the window lies in a plane that is generally perpendicular to the axis.

18. The system of claim 11, wherein the window lies in a plane that is inclined at an angle to the axis.

19. The system of claim 11, wherein the system includes a desk-top computer on which the download port is located.

20. The system of claim 11, wherein the system includes a lap-top computer on which the download port is located.

21. The system of claim 11, wherein the system includes a peripheral module on which the download port is located, the module having a generally planar base for supporting the module on a generally planar support surface.

22. The system of claim 21, wherein the cavity extends along a port axis that is inclined relative to the base.

23. The system of claim 11, wherein the download port is in electrical communication with a global computer network having a server on which information relating to the data is stored, and wherein the server is operative for delivering the information.

24. The system of claim 23, wherein the network includes a display, and wherein the server delivers the information by displaying the information on the display.

25. The system of claim 11, wherein the user information includes a billing number for the user.

26. The system of claim 11, wherein the user information includes a billing address for the user.

27. A method of electro-optically collecting and downloading data, and of retrieving information based on the data, comprising the steps of:

a) providing a user with a portable, dual-use instrument for marking surfaces by the user, and for electro-optically collecting data selected by the user, the instrument being sized and shaped to be carried by the user;

b) marking a surface to be marked with a marker on the instrument by holding the instrument by and among fingers of a single hand of the user;

c) electro-optically collecting data by holding the instrument by and among the user'"'"'s fingers, and by directing a light beam at a bar code symbol, by detecting light reflected off the symbol, by generating an electrical signal indicative of the detected light, by processing the electrical signal into a processed signal, and by storing the processed signal and user information uniquely identifying the user on-board the instrument;

d) downloading the stored signal and the stored user information to a server having the information to be retrieved, by having the user insert a part of the instrument into a download port; and

e) retrieving and displaying the information to the user.

28. The method of claim 27, wherein the marking step is performed by marking the surface with a fluid.
