Patent number: 6947808Abstract: A method and system are disclosed for automatically generating embroidery designs from a scanned image. An embroidery data generating mechanism generates accurate embroidery designs. The embroidery data generating mechanism first reads an image data file, which contains bitmapping information generated from a software scanning tool, the information being related to an embroidery pattern that has been scanned. The scanned pattern is broken up into pixels, each pixel in the scanned image having a bitmap associated with the color of the pattern. Each unique color in the scanned pattern has its own unique bitmap. The embroidery generating mechanism also includes a segmentation mechanism and a chain-encoding mechanism which perform operations to enhance the quality of the bitmapped information and to separate regions of the scanned image into objects. A distance transform evaluation mechanism classifies each object as being either a thick object or a thin, predominantly regular object.Type: GrantFiled: March 23, 2004Date of Patent: September 20, 2005Assignee: SoftSight, Inc.Inventor: David A. Goldman

Patent number: 6889111Abstract: Type information on sewing machine types and identification information for specifying a sewing machine are stored in a control unit and computer of the sewing machine. A server transmits display data for displaying a pattern selection edit screen to the sewing machine side. At the sewing machine side, a pattern is selected while the pattern selection edit screen is being viewed, and an edit processing is instructed. The server edits an embroidery pattern ordered at the sewing machine side, based on the instruction supplied from the sewing machine side. The server transmits the display data and sewing pattern data to the sewing machine side. Incorporated patterns and non-incorporated patterns at the sewing machine side are displayed identifiably on a display at the sewing machine side. The server charges for the non-incorporated newly purchased patterns.Type: GrantFiled: March 20, 2002Date of Patent: May 3, 2005Assignee: Brother Kogyo Kabushiki KaishaInventor: Shintaro Tomita
