A data storage unit configured to store a sewing order and a coordinate data of a needle location in association with each other; a coordinate data adding unit configured to create the coordinate data of a new needle location on a line connecting three or more continuous needle locations in a sewing order stored in the data storage unit in accordance with a distance from the needle locations located at both ends of the line to the needle location located at an inside of the both ends when the three or more continuous needle locations are on the line; and an added coordinate data creating unit configured to create a new coordinate data by adding independent original values to the X-coordinate value or the Y-coordinate value in each of the coordinate data are provided.

Disclosed is a guiding apparatus for use with a machine to facilitate performing an action along a self-guided path on a substrate. The guiding apparatus may include a support member configured to be attached to at least a portion of the machine. Further, the guiding apparatus may include one or more of lighting units, optical sensors, controllers, and user interface components, mounted on the support member, configured to identify an object, obtain position of the object on a substrate and perform an action along a self-guided path in association with that object on the substrate.

A sewing machine detects a sewing status after a change, when the sewing status changes. When the sewing machine receives a status request requesting the sewing status, from an information terminal via a LAN, the sewing machine transmits, to the information terminal, sewing status information that accords with the detected sewing status. When the detected sewing status satisfies a predetermined condition, the sewing machine transmits a notification request, which includes identification information identifying the information terminal, to a server, in order to cause the server to transmit, to the information terminal, a notification command instructing a push notification in the information terminal.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate augmented-reality features such as projecting assistive visual elements or virtual UI elements into an operational area. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate patch library systems that may enable the storage and retrieval of patch configuration information. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate 3-dimensional vision systems that may enable operations on non-flat objects and paths. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

A coordinate data generator includes a coordinate data storage to store coordinate data, and a post-addition coordinate data generation section to respectively add independent values to the X coordinate value or the Y coordinate value of the coordinate data for each item of the coordinate data stored in the coordinate data storage, so as to generate new coordinate data in which a pattern has been distorted.

A data storage unit configured to store a coordinate data of a needle location and an added coordinate data creating unit configured to create a new coordinate data by adding independent original values respectively to an X-coordinate value or a Y-coordinate value for each of the coordinate data stored in the data storage unit are provided. The added coordinate data creating unit makes the independent original values added respectively to the X-coordinate value or the Y-coordinate value of the coordinate data in one needle location same as the independent original values added respectively to the X-coordinate value or the Y-coordinate value of the coordinate data in the other needle location when a distance between the coordinate data of the one needle location and the coordinate data of the other needle location stored in the data storage unit is within a predetermined distance.

Disclosed is a method for producing a sewing data file using an embedded computer. A method for producing a sewing data file of a sewing machine allows the embedded computer to perform the following processes: receiving a color of a thread mounted on the sewing machine through the touch input device and the data input device; receiving an image data through the network device; extracting a color component from the image data by referring to a color of a thread mounted on the sewing machine using the sewing data conversion program; and calculating a ratio occupied by a color of a minimum unit pixel for each separated color as an area occupied by a thread using the sewing data conversion program and converting the calculated ratio into a sewing data in a linear shape and a zigzag shape.
