Abstract: Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated fashion. For example, information describing a shoe part may be determined, such as an identification, an orientation, a color, a surface topography, an alignment, a size, etc. Based on the information describing the shoe part, automated shoe-manufacturing apparatuses may be instructed to apply various shoe-manufacturing processes to the shoe part, such as a pickup and placement of the shoe part with a pickup tool.

Abstract: A luggage fastener comprising a female engagement member and a male engagement member, wherein the female engagement member includes a recessed center adjoining member, which can be directly riveted onto the luggage. In securing the male and female engagement members, the hooks of the male engagement member are inserted into the sockets of the female engagement member, while the attachment member is inserted into the adjoining member by guiding the ribs on the male engagement member along the grooves on the female engagement member. Two L-shaped openings at the rear ends of the sockets further facilitate a quick unfastening of the secured engagement members. The benefits of this invention include the elimination of the fabric strap, the reduction of part of the female engagement member, and the resulting material savings as compared to the conventional design of the prior art.
