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 sewing system includes a cutting device and a sewing machine. The cutting device acquires the cutting data and send the cutting data via at least one of the network line or at least one of the wireless communication by the cutter communication portion. The sewing machine receives the cutting data sent by the cutting device via at least one of the network line or at least one of the wireless communication. The sewing machine generates the embroidery data, based on the cutting data received by the sewing machine. The sewing machine sews on the object to be sewn, based on the generated embroidery data.

An operating method for computerized machine embroidery includes steps of: (a) transmitting two portions of the stitch data sets respectively into a first storage section and a second storage section; (b) embroidering according to the portion of the stitch data sets in the first storage section; (c) after completion of step (b), the embroidery machine erasing data from the first storage section; (d) after completion of step (c), the transmitting a remaining portion of the stitch data sets to the first storage section; (e) after completion of step (b), embroidering according to the portion of the stitch data sets in the second storage section; and (f) repeating step (b) after completion of steps (d) and (e).

In a sewing machine, an arm includes, on one side thereof in a first direction, a head. A needle bar is disposed at the head to reciprocally move in a second direction. A feed mechanism feeds a workpiece from one side toward the other side of the head in a third direction. The projection unit disposed at the head projects a projection image toward a bed. The projection unit includes an emitter for projecting image light of the projection image. The photographing unit disposed at the head captures a photographing target. The photographing unit includes an incident portion on which light reflected by the photographing target is incident. The emitter and the incident portion are disposed further toward the one side of the arm in the first direction than the needle bar, and further toward the one side of the head in the third direction than the needle bar.

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.

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.

An operating method for computerized machine embroidery includes steps of: (a) transmitting two portions of the stitch data sets respectively into a first storage section and a second storage section; (b) embroidering according to the portion of the stitch data sets in the first storage section; (c) after completion of step (b), the embroidery machine erasing data from the first storage section; (d) after completion of step (c), the transmitting a remaining portion of the stitch data sets to the first storage section; (e) after completion of step (b), embroidering according to the portion of the stitch data sets in the second storage section; and (f) repeating step (b) after completion of steps (d) and (e).

A sewing-machine operating program is installed in a terminal device of a user. A specifying information acquiring step causes a short-distance information acquiring unit to acquire specifying information recorded on a sewing-machine main unit. In the distance measuring step, an apart distance is calculated from a detection result of a movement detecting sensor with a position where the specifying information is acquired being as an initial position. In the distance comparing step, for a remote operation to the sewing-machine main unit, the apart distance and a prescribed distance are compared. In the function restricting step, when the apart distance is within the prescribed distance, an operation command is transmitted to the sewing-machine main unit via a wireless communication device, and when the apart distance exceeds the prescribed distance, the operation command is not transmitted to the sewing-machine main unit.

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 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.
