Publication number: 20140034398Abstract: 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.Type: ApplicationFiled: October 7, 2013Publication date: February 6, 2014Applicant: Datalogic ADC, Inc.Inventors: Charles Forrister Atwater, Alexander M.

Patent number: 8571298Abstract: An system and method for tallying objects presented for purchase preferably images the objects with a machine vision system while the objects are still, or substantially still. Images of the objects may be used to recognize the objects and to collect information about each object, such as the price. A pre-tally list may be generated and displayed to a customer showing the customer the cost of the recognized objects. A prompt on a customer display may be given to urge a customer to re-orient unrecognized objects to assist the machine vision system with recognizing such unrecognized objects. A tallying event, such as removing a recognized object from the machine vision system's field of view, preferably automatically tallies recognized objects so it is not necessary for a cashier to scan or otherwise input object information into a point of sale system.Type: GrantFiled: December 11, 2009Date of Patent: October 29, 2013Assignee: DATALOGIC ADC, Inc.Inventors: Alexander M.

Patent number: 8561906Abstract: Optical reading system and methods having multiple modes of operation, for example: omnidirectional and single-code picking; fixed and handheld reading; 1D and 2D code reading. In one configuration, an image-based system obtains input data via an area sensor (e.g., a 2D CCD array) with only data corresponding to a pattern of virtual scan lines being stored and processed. A user may implement different operating modes such as a first mode reading codes in any location or orientation and a second mode reading only a code oriented along a particular virtual scan line or group thereof. Alternately, the data reader is operable to switch between handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change within or between frames.Type: GrantFiled: February 3, 2012Date of Patent: October 22, 2013Assignee: Datalogic ADC, Inc.Inventor: Robert W. Rudeen
