Abstract
A hand-supportable digital-imaging based system for reading bar code symbols involving: automatically detecting the presence of an object within a field of view FOV of the system, and in response thereto, automatically generating an image cropping zone (ICZ) framing pattern and projecting the ICZ framing pattern within the FOV and onto the detected object; visually aligning the code symbol on the detected object, within the ICZ framing pattern; manually actuating a trigger switch when the code symbol on the object is located within the ICZ framing pattern, and while the ICZ framing pattern and a field of illumination are being simultaneously projected onto the object during object illumination operations, forming and capturing a digital image of the code symbol on the detected object; automatically cropping the image pixels contained within the spatial boundaries of the ICZ framing pattern, from the pixels of the digital image; and decode processing the cropped image so as to read one or more 1D and/or 2D code symbols graphically represented therein.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
