An invisible zipper head assembly structure includes a sliding member and a pulling member. The sliding member has a base portion, a first lateral wall portion, a second lateral wall portion, a seat portion, an elastic component, and a retaining body. The retaining body has a positioning portion passing through a positioning through hole of the seat portion. The pulling member is movably mated with the retaining body. The thickness of the first lateral wall portion is smaller than the thickness of the second lateral wall portion. The first symmetric center line of the base portion passes through a geometric center point of the positioning through hole, and the second symmetric center line of the seat portion is horizontally moved relative to the first symmetric center line by horizontal offset and along a horizontal direction from the second lateral wall portion to the first lateral wall portion.

The system provides publishers with abstract fulfillment such that they only have to upload content for a product one time to a server or other device configured as an open, neutral electronic distribution platform that can provide third party verification to the publisher of a transaction between the retailer and the consumer for that publisher's product. Content selected from the server by different retailers is dynamically rebranded using the retailer-specific information corresponding to those respective retailers prior to deliver to consumers.

A robotic zipper system for joining and separating zipper halves of a zipper tape. A chassis retains an actuator that drives a zipper slide geometry along the zipper tape to join or separate the zipper tape. A sensor can determine zipper slide position, and a control module can provide an electrical signal to the motor to move in forward or reverse. The actuator can have a motor that drives a gear system that mechanically engages zipper teeth. Teeth of the gear system can be out of phase to mesh with alternating gaps between the zipper teeth. The actuator can be removable relative to a zipper slide. Zipper slide geometry could be integrated into the chassis, such as in the form of a channel, potentially with a central post. A sensor could be positioned to detect the presence or absence of zipper teeth through an opening in a base plate.
