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.

A positioning structure for a movable tongue seat includes: an eccentric positioning member disposed between the movable tongue seat and the cutter seat, the eccentric positioning member is provided with a rotary end which is located toward one end of the cutter seat, wherein the eccentric positioning member rotates about the rotary end and is further provided with a drive end which is inserted in a slot of the movable tongue seat, the drive end and the rotary end are not coaxially aligned; and a pivot hole and a pivot provided between the movable tongue seat and the cutter seat, so that the movable tongue seat is able rotate on the cutter seat by rotating about the pivot. When the eccentric positioning member rotates about the rotary end, the drive end can push the movable tongue seat to rotate about the pivot to a desired position.

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.
