Publication number: 20230222779Abstract: A method is provided for identifying consumer packaged goods (CPGs). The method includes providing to a machine learning classifier a set of images containing at least one CPG; receiving from the machine learning classifier an indication that the machine learning classifier cannot reliably identify a designated CPG in the set of images; determining whether the designated CPG is a product in a product catalog; if the designated CPG is in the product catalog, then associating the designated CPG with a Global Trade Item Number (GTIN); and if the designated product is not in the product catalog, then designating the CPG as a potentially new product. Notably, this approach allows partially identified products to be treated as full-fledged members of the product catalog, thus allowing data to be collected on these products even before they have been fully identified and their GTINs have been resolved.Type: ApplicationFiled: January 11, 2023Publication date: July 13, 2023Inventors: Greg Stuart Hilton, Joel William Iventosch, Catherine Ann Malloy, Michael John Pav

Patent number: 9482468Abstract: A first heat-treating method involves monitoring at least one thermal efficiency parameter associated with an irradiance system configured to produce an irradiance flash incident on a surface of a workpiece, and automatically updating control information used by the irradiance system to produce the irradiance flash, in response to the monitoring of the thermal efficiency parameter. A second method involves predicting a heating effect of an irradiance flash to be incident upon a surface of a workpiece, in response to a measurement of a heating parameter of the surface, and pre-adjusting the irradiance flash, in response to the predicted heating effect. A third method involves measuring a temperature of a surface of a workpiece during an initial portion of an irradiance flash incident on the surface, and controlling a power of a remaining portion of the irradiance flash, in response to the temperature.Type: GrantFiled: September 14, 2006Date of Patent: November 1, 2016Assignee: Mattson Technology, Inc.Inventors: David Malcolm Camm, Sergiy Dets, Kevin McDonnell, Greg Stuart, Tilman Thrum, Igor Rudic, Ljubomir Kaludjercic

Patent number: 8693857Abstract: A method of heat-treating a workpiece includes generating an initial heating portion and a subsequent sustaining portion of an irradiance pulse incident on a target surface area of the workpiece. A combined duration of the initial heating portion and the subsequent sustaining portion is less than a thermal conduction time of the workpiece. The initial heating portion heats the target surface area to a desired temperature and the subsequent sustaining portion maintains the target surface area within a desired range from the desired temperature. Another method includes generating such an initial heating portion and subsequent sustaining portion of an irradiance pulse, monitoring at least one parameter indicative of a presently completed amount of a desired thermal process during the irradiance pulse, and modifying the irradiance pulse in response to deviation of the at least one parameter from an expected value.Type: GrantFiled: July 13, 2011Date of Patent: April 8, 2014Assignee: Mattson Technology, Inc.Inventors: David Malcolm Camm, Steve McCoy, Greg Stuart
