## Background
RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application No. 60/568,240, entitled “Scannable Article Having A Signature Section With Alignment Bars,” which was filed on May 6, 2004, the disclosure of which is hereby expressly incorporated herein by reference.


FIELD OF THE INVENTION
This invention relates generally to a scannable article having a signature section, and more particularly, to a scannable article having a signature section with alignment bars.
BACKGROUND OF THE INVENTION
The United States Postal Service (USPS) is an independent government agency that provides mail delivery and other services to the public. The USPS is widely recognized as a safe and reliable means for sending and receiving mail and other items. With the advent and steady growth of electronic mail and electronic commerce, the physical mail stream will increasingly be utilized for sending and receiving packages and other items. In an effort to ensure that mail is delivered not only to the right address, but also into the right hands, the USPS offers tracking of the mailed item in conjunction with many special service options.
Tracking of a mailed item may provide routing information allowing an item to be sent from point A to point B. Tracking may also provide information such as, for example, where the item came from, who prepared the item, when the item was prepared, or where the item is in the item delivery system. Tracking is typically accomplished by affixing a scannable label (e.g., a barcode) to the mailed item and scanning the label at specific checkpoints along a delivery route. The final checkpoint in the route may be the point of delivery, when the mail carrier scans the mailed item just prior to delivery of the mailed item to the recipient.
The special service options may include services such as, for example, delivery confirmation, signature confirmation, certified mail, registered mail, and others. These special service options may provide an added level of security by requiring a signature from the person who accepts the delivery. The signature may be co-located on an adhesive label with the tracking information described above.
During the final step of the tracking process described above, the recipient's signature and the tracking information of the mailed item, may both be scanned. Unfortunately, scanning of a signature can be difficult. In particular, depending on the character of the signature and its orientation, alignment and resolution of the scanned signature may be problematic.
It is accordingly a primary object of this invention to provide a method and apparatus that improves alignment and resolution of a scanned signature.
SUMMARY OF THE INVENTION
In one aspect, the present disclosure is directed to an article scannable by a data capture device that has an informational surface and a signature section disposed on the informational surface. The signature section has a signature area and at least two alignment bars including a first alignment bar disposed on a first end of the signature section relative to writing direction and a second alignment bar disposed at the end of the signature section opposite the first end, the alignment bars being within the signature section.
In another aspect, the present disclosure is directed to a method of reducing misalignment and poor resolution of a scanned signature on an article. The method includes providing an article having an informational surface.

INDUSTRIAL APPLICABILITY
The disclosed signature section, having alignment bars 30, may be applicable to any scannable article such as, for example, an adhesive label, a mailing label, or any other suitable form article requiring scanning. Alignment bars 30 may reduce alignment and resolution problems associated with detecting, reading, or storing a handwritten signature in at least two ways.
The first way to reduce the alignment and resolution problems may be by comparing a general physical location of a data capture device relative to the alignment bars. For example, whether the data capture device is handheld or automatically positioned, alignment bars 30 may provide an initial target for placement of the data capture device. If handheld, an operator of the data capture device can substantially align the data capture device within the signature area by visually comparing a distance between an outer structure of the data capture device and alignment bars 30 or by visually comparing an angle between an outer structure of the data capture device and alignment bars 30. If the distance or the angle difference is greater than a predetermined value, the data capture device may be repositioned by moving the data capture device in a direction of decreasing difference. Similarly, a structure of the data capture device may be automatically compared to a position and/or orientation of alignment bars 30 for initial placement of the data capture device prior to scanning.
The second way to reduce alignment and resolution problems may be to calibrate a position and/or orientation of the data capture device relative to alignment bars 30. Once positioned within the signature area of the form article, the data capture device may be configured to perform calibration processes based on an error value being greater than a predetermine value. The error value may be generated by comparing a captured dimension of alignment bars 30 with one or more predetermined calibration values. The captured dimension may include, for example, a distance between alignment bars 30, length of one or both alignment bars 30, a thickness, a shade, an orientation of alignment bars 30, and/or an angle between alignment bars 30. The error values determined through the calibration processes may then be used to either change scan settings of the data capture device or require re-positioning of the data capture device prior to scanning signature section 16. The calibration process may also be used to offset, skew, or otherwise modify already scanned images.
Other embodiments of the disclosed scannable article 10 will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. For example, the entire scannable article 10 may be scanned and electronically stored. Further, a greater of lesser number of sections may be included on scannable article 10 and the sections may be in a different order. Scannable article 10 may also have a different shape than that in the present disclosure. Alignment bars 30 may also be included in sections other than the signature section. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being defined by the following claims.
