Intelligent connection systems disclosed herein perform autonomous connection mechanisms and provide secure connectors. A mobile device exemplifies one of the embodiments of the autonomous connection mechanism.

A method of producing a deflector device for a fuel tank system comprising producing a deflector device prototype from prefabricated components of a construction kit, performing fuel-refilling tests using the deflector device prototype, optionally modifying the deflector device prototype, creating a construction model for the deflector device prototype, producing a deflector device according to the construction model, optionally performing fuel-refilling tests with the deflector device produced according to the construction model and optionally producing the deflector device according to the construction model. The disclosure further provides a construction kit with prefabricated components for producing the prototype of the deflector device for the fuel tank system.

A screw fastening method includes reversely rotating a shaft part of a fastening tool in a direction of loosening one of an external thread and an internal thread, which is engaged with the shaft part, while one of the external thread in a non-screwed state and the internal thread in a non-screwed state, which is engaged with the shaft part, is pressed against the other thread, detecting collisions between thread ridges of the external thread and the internal thread using a sensor while the shaft part remains rotated reversely, determining whether or not a time interval between collisions detected by the sensor matches a theoretical cycle of collisions calculated from rotation speed of the shaft part, and fastening the external thread and the internal thread to each other by normally rotating the shaft part when it is determined that the time interval matches the theoretical cycle.

A machining tool assembly for manufacturing a firearm lower receiver includes a first and second side jig which are configured to be disposed on opposite sides of the firearm lower receiver and configured to removably attach to one another securing the firearm lower receiver therebetween. A drill block jig is removably attachable to the first and second side jigs disposed above the top surface of the firearm lower receiver, wherein the drill block jig comprises a plurality of through holes. A template spacer jig is removably attachable to the first and second side jigs disposed above the top surface of the firearm lower receiver, wherein the template spacer jig comprises a spacer aperture disposed through a template spacer thickness. A first and second pocket templates are removably attachable and disposed onto the template spacer jig. A router support plate is disposed onto either the first or second pocket templates.

A method for producing or assembling a product which includes at least two components, for example a motor vehicle or a motor vehicle module, by at least two fixing parts. The first fixing part is formed as a female part and the second fixing part is formed as a male part. The components disposed at a processing station and the first fixing part are measured by a measuring device, for example by a stationary camera or a camera fastened on a first or a second manipulator or photogrammetry bar having three cameras, and a deviation from a target geometry or target position is determined, and a corrected target position of the second fixing part is calculated on the basis of the determined deviation, such that the second fixing part is joined together with the first fixing part by the first manipulator and the product is thus produced.

A joining method is a method of joining a plate set composed by a plurality of stacked plate members including a first plate member and a second plate member by using a tapping screw. When the tapping screw is advanced into the plate set while the tapping screw is rotated in a state of applying a pressure onto the plate set so as to form through-holes in the first plate member and the second plate member, a first pressure applied onto the tapping screw is reduced down to a second pressure at the time when the tapping screw penetrates the first plate member.

A system for positioning post sleeves is provided including a plurality of post sleeve positioning devices and a spacing mechanism. Each post sleeve positioning device is configured to receive a respective post sleeve and to enable selective adjustment of a position and orientation of the respective post sleeve. The spacing mechanism is coupleable between the pair of post sleeve positioning devices to determine or control the position and orientation of the post sleeve received by one of the pair of post sleeves positioning devices relative to the post sleeve received by the other one of the pair of post sleeve positioning devices. Related systems and methods are also provided.

A machining tool assembly for manufacturing a firearm lower receiver includes a first and second side jig which are configured to be disposed on opposite sides of the firearm lower receiver and configured to removably attach to one another securing the firearm lower receiver therebetween. A drill block jig is removably attachable to the first and second side jigs disposed above the top surface of the firearm lower receiver, wherein the drill block jig has at least one through hole. A router support plate is disposed above and removably attachable to the first and second side jigs. A router aperture is disposed through a router support plate thickness.

Disclosed herein are self-aware, self-modifying, autonomous connection mechanisms. Exemplifying intelligent systems introduce some of the embodiments of the autonomous connection mechanism techniques.

A stent-graft, including a generally tubular vascular graft of biocompatible material, and a plurality of bio-resorbable discrete annular members spaced apart along a longitudinal axis of the vascular graft and attached thereto.
