Abstract: An aircraft door mechanism includes at least an aircraft structure that delimits an opening, and an aircraft door mounted so as to be movable relative to the structure between a closed position that closes the opening, and a boarding position, in which the door is arranged away from the opening and in which passengers are able to board the aircraft structure through the opening. The aircraft door mechanism includes also a control system configured so as to control the execution of a closing operation and the execution of an opening operation of the door, the control system including a drive shaft, with the control system being configured so as to control the execution of said operations by means of continuous rotation of the drive shaft relative to the aircraft structure.

Abstract: An aircraft door mechanism includes an aircraft structure (14) delimiting an opening (24); an aircraft door (26) movable between a position closing off the opening (24) and a released position of the opening (24); and a guide system (28) for moving the door (26) between the closed off and released positions. The guide system (28) includes a main rail (46) that is fixed relative to the structure and a main carriage (48) mechanically connected to the door (26) and able to slide on the main rail (46) during the movement between said closed off and released positions. The main rail (46) is positioned between the door (26) and the structure during at least part of the movement of the door (26) between said closed off and released positions.

Abstract: Systems and methods for distributed database management are disclosed. In an embodiment, a method of accessing information in a distributed database system having one or more data servers includes establishing a plurality of lattice structures configured to store data elements having inter-related information. A data query initiated by a client is then formulated that includes selected data attributes. The data query is processed to generate a query product, and the plurality of lattice structures are searched to identify data elements corresponding to elements in the query product. Pertinent data files located within another data server are accessed that correspond to the data query and generating a result, and the result is transferred to the initiating client system.
