An example method includes determining, by a computing system, a dry thickness of a fabric preform. The method also includes determining, by the computing system, a debulked thickness of the fabric preform using the dry thickness of the fabric preform. In addition, the method includes determining, by the computing system, a stitch tension using the dry thickness of the fabric preform and the debulked thickness of the fabric preform. And the method includes causing, by the computing system, a stitching machine to apply a through-the-thickness stitch having the stitch tension to the fabric preform.

Apparatuses, methods, and computer program products for quilting webs without compressing the webs. A quilting machine includes a needle bar to which needles are attached, needle thread passing through each needle, a looper shaft to which loopers are attached, a looper corresponding to each needle and from which looper thread is provided to form stitches, and a retainer bar to which spreaders are attached to facilitate stitching. A drive pulley powered by a first servo motor rotates cranks to move the needles through a cycle and rotates a belt which rotates an indexer pulley. Rotation of the indexer pulley oscillates the looper shaft and reciprocates the retainer bar. Another drive pulley powered by a second servo motor operates to move an input web through the machine between chain stiches.

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.

A sewing machine includes a first image acquisition unit, a second image acquisition unit, and a display unit. In the sewing machine, the first image acquisition performs image acquisition from the front face side of a cloth for a stitching pattern formed in the cloth. The second image acquisition unit performs image acquisition from the back face side of the cloth such that the center position of the acquired image matches the center position of the image of the stitching pattern acquired by the first image acquisition unit. The display unit displays, on the same screen, a first stitching pattern video image thus acquired by the first image acquisition unit and a second stitching pattern video image thus acquired by the second image acquisition unit.

A textile production monitoring system includes an electronic device connected with a sewing machine, and with sensors connected with the knife, the pedal, the motor tach of the sewing machine, and with the needle, the sensors transmitting signals to the electronic device. A microprocessor evaluates the four signals received from the sensors in a coordinated way. A software possessing a four-signal algorithm generates information about the products, information on which operator works on which machines for how long, how much product they produce, failure status, and machine efficiency. An Rfid module is connected with the electronic device for monitoring the information and working status of the personnel working on the sewing machine. At least one barcode reader allows for entering information on which order the product sewn in the sewing machine belongs to. A wireless connection module facilitates transfer of the information from the electronic device and the microprocessor wirelessly.

An automated system that can be used for prosthetic heart valve manufacturing or suturing procedures. The system can include a first automated fixture that includes an articulating arm and a target device holder. The system can also include one or more additional automated fixtures, which can be configured as one or more suturing arms that include another articulating arm and a needle holder. The first automated fixture can be configured to rotate a target device held by the holder to allow the one or more additional automated fixtures to perform operations such as form sutures on the target device without intervention of a human operator. The system can include a display system configured to display status information of a suturing procedure.
