An embroidery data generation system includes a terminal apparatus and an embroidery data generation apparatus. A terminal controller acquires a generation condition of embroidery data inputted via an input device, transmits the acquired generation condition to the embroidery data generation apparatus via a terminal communication interface, and controls a display to display a preview image indicating an embroidery finish of an embroidery pattern based on image data transmitted from the embroidery data generation apparatus. An apparatus controller receives the generation condition transmitted from the terminal apparatus via an apparatus communication interface, generates the embroidery data for sewing the embroidery pattern based on the received generation condition, generates the image data for displaying the preview image on the display based on the received generation condition, and transmits the generated image data to the terminal apparatus having transmitted the generation condition.

A sewing machine determines a pattern from multiple patterns, as a first pattern. The sewing machine generates a projection image including a first image representing a sewing image of the first pattern in a sewing expected size thereof. The sewing machine projects the generated projection image onto a projection area. The sewing machine sews the first pattern on a workpiece in the sewing expected size based on pattern data for the first pattern.

A communication system is provided for a yarn creel with sensors and displays located throughout the array of yarn positions and communicating with a creel controller to facilitate transfer and display of thread-up information and analysis of operational data.

A software activation system includes a sewing machine and at least one server connected via a network. The sewing machine acquires an authentication code corresponding to an activation target software that is at least one of a program and data not activated on the sewing machine, and transmits, to an authentication server included in the at least one server, an authentication request including the acquired authentication code. The server acquires an authentication key on the basis of the authentication request, when the authentication request is received by the first receiver; and transmits the acquired authentication key to the sewing machine. The sewing machine also receives the authentication key from the authentication server, determines whether the received authentication key satisfies a predetermined authentication condition, and activates the activation target software on the sewing machine when it is determined that the authentication key satisfies the predetermined condition.

A sewing error management device includes a display portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to acquire an error image obtained by drawing an occurrence position of an error on a sewing pattern. The acquiring the error image is based on coordinates representing a formation position of a sewing stitch being sewn at a time point when the error occurs in sewing of the sewing pattern formed by a plurality of sewing stitches. The acquiring the error image is also based on an image showing a shape of the sewing pattern. And the computer-readable instructions further instruct the processor to display the acquired error image on the display portion.

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.

Presented are a method, apparatus, and computer-readable medium for stitching. The method includes examining, by an examiner, an embroidery design, wherein the examiner is operably coupled to a controller and a sewing head, and wherein the controller comprises a memory having a capacity, and wherein the controller is operable to cause the sewing head to stitch a work piece. The method further includes determining, by the examiner, a needle drop location of each stitch of the embroidery design, and dividing, by the examiner, the examined embroidery design into a plurality of separate sections. The method still further includes transmitting the plurality of separate sections at a plurality of different times to the controller such that the controller the plurality of separate sections do not exceed the capacity of the memory at any one of the plurality of different times.

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.
