US Patent:

6454168, Sep 24, 2002

Filed:

Sep 13, 1999

Appl. No.:

09/394340

Inventors:

Jonathan R. Brandt - Eugene OR
Glen W. Davis - Junction City OR
Charles F. Atwater - Eugene OR

Assignee:

PSC Scanning, Inc. - Eugene OR

International Classification:

G06K 710

US Classification:

23546212, 23546201, 235454, 23546216

Abstract:

In a bar code scanning system, correlation and stitching techniques, both at the character and element level are utilized to assemble complete label information from partially scanned label segments. Correlation may require the same characters to be identified a fixed number of times in the same position before acceptance. Alternatively, quality and confidence measures may be implemented to determine the number of times a particular character must be decoded before being accepted. In a preferred implementation, a decoded character that is determined to be of poor quality may be required to be decoded as that same character a greater number of times than if it were of good quality. Identified correlation techniques may be combined with identified stitching techniques to enhance decodability and efficiency of assembling complete label information.

Appl. No.:

11/861276

Inventors:

Nicolas N. Tabet - Eugene OR, US
Craig D. Cherry - Eugene OR, US
Charles F. Atwater - Eugene OR, US

Assignee:

Datalogic Scanning, Inc. - Eugene OR

International Classification:

G08B 13/14

US Classification:

3405724, 235385

Abstract:

A system and method for reading multiple items bearing electronic tags, such as radio frequency identification (RFID) tags, disposed in a read zone wherein a correlation scheme/system, separate (e. g. non-RF) from the electronic reader, is provided for verifying that all the items in the read zone have been successfully read. Typically, the user/operator is then notified whether or not all the items detected by the verification system have been successfully read by the electronic reader.

Assignee:

Datalogic ADC, Inc. - Eugene OR

International Classification:

G06K 7/10

US Classification:

177 2515, 177 45, 177 50, 177245, 235383, 23546213

Abstract:

Systems and methods are provided for reducing erroneous weighing of items by detecting items extending beyond a peripheral edge of a weigh platter associated with a data reader. For example, in response to a weigh request a scale guard module acquires data indicative of whether an item extends between the weigh platter and another surface, compares the acquired data to reference data, and based on the comparison, determines whether an item extends off the weigh platter and thus on to another surface. The scale guard module may utilize non-electromagnetic compression waves, radio waves, a portion of a data reader's scan field to scan a set of patterns extending along at least one edge of the weigh platter, an imaging based scanner to capture an image of at least one edge of the weigh platter, light beams extending along at least one edge of the weigh platter, or any combination thereof.

Scott Gerald Horn - Eugene OR, US

International Classification:

G06K 7/10
G06K 15/00
G06K 7/14

Abstract:

A method of scanning an object may include determining that an object is proximately positioned relative to a scanning volume of a presentation scanner in response to receiving at least one object presence signal prior to scanning a code indicia positioned on the object. At least one object sensory indicator device may be activated in response to determining that the object is proximately positioned relative to the scanning volume so as to indicate that the object is proximate to the scanning volume to a user. A second level of detection and location feedback may be provided for code indicia within the scanning volume.
