Abstract: Aspects of the disclosures allow for a touchless or hands-free closing, opening, and holding (in a closed state) of a door system, including, but not limited to doors for stalls in public restrooms. Embodiments of the door opening system may include touchless mechanisms and methods that utilize various mechanical, electromechanical, and/or electronic systems and components. Aspects of the disclosures also allow for occupancy indication for a door system, including, but not limited to doors for stalls in public restrooms. Embodiments of the occupancy indication system may include an occupancy indicator that may be pushed away from a door panel to indicate whether the bathroom stall is occupied or not occupied.

Abstract: A flexible manufacturing system utilizing modular work stations configured to provide asynchronous operations on a plurality of work pieces mounted on fixtures or pallets that are transported through the system by means of a conveyor or rail arrangement. The pallets are diverted from the track on which they are transported linearly to a desired machining module adjacent to, but removed from, the track, such that the machining is performed in a chamber isolated from the track. Each machining module may be utilized in more than one location on the track and the modules may be interchanged depending on the desired operation sequence and the tools available in each of the machining station modules.
