Abstract: A system enabling hands-free operation of controls for accessing a transportation vehicle is provided. The system comprises code readers associated with respective entry barriers for admitting passengers to a transportation vehicle. The code readers read a machine-readable passenger code generated by a mobile electronic device and actuate mechanisms allowing entry through the barriers responsive confirmation of the code. A signal receiver in communication with a Passenger Service Unit for passenger seat onboard the vehicle receives instructions from the mobile electronic device and instruct the PSU to actuate passenger cabin controls for the passenger seat. An application on the mobile electronic device determines a time-stamped temperature of a passenger and generates the passenger code, which includes passenger identification, authorization to pass through the entry barriers and board the vehicle, and a determination if the temperature of the passenger indicates an acceptable passenger health status.

Abstract: A method of operating a 3-D printer apparatus includes a tank structure with a bottom wall with a printing area defined above and spaced apart from the bottom wall. A gas permeable liquid within the tank overlays the bottom wall of the tank structure defining a first mobile layer below the printing area. An inhibition liquid within the tank overlays the gas permeable liquid defining a second mobile layer below the printing area. A polymerizable resin overlays the inhibition liquid and flows into the printing area. Positioning of an object carrier controlled such that a lower surface of the object carrier is initially located within the polymerizable resin and within the printing area. Operation of a resin curing device beneath the bottom wall provides light to the printing area polymerizing predetermined portions of the polymerizable resin forming an object attached to the lower surface of the object carrier.

Abstract: A 3-D printer apparatus (three-dimensional printer apparatus) includes a bottom structure of a tank. The tank defines a printing area located above and spaced apart from the bottom structure. The bottom structure includes oxygen releasing electrodes. A resin curing device is configured to selectively provide light to the printing area. The electronic controller controls operation of the resin curing device and the oxygen releasing electrodes. The electronic controller selectively operates areas of the oxygen releasing electrodes thereby releasing oxygen to predetermined locations below the printing area in order to temporarily prevent the polymerization of a polymerizable resin within predetermined locations of the printing area during the printing process.
