专利汇可以提供Electronic system employing plural processing stations for issuing airline boarding passes while effecting seat assignments, and generally for parcelling elements of an ordered set专利检索，专利查询，专利分析的服务。并且A digital, electronic system for issuing airline boarding passes, while effecting aircraft seat assignments, employs a central processor unit connected via a plurality of system busses to a plurality of parallel connected keyboard units each having a boarding pass enscribing alpha-numeric printer associated therewith. The central processor includes a circulating memory for storing information characterizing the availability of seats for the particular aircraft in service, while the keyboard units include a lamp matrix for displaying seat availability in a section (zone) of the aircraft selected by a passenger. The central processor sequentially and cyclically polls all on line keyboard units, accommodating all proper seat requests while maintaining real time supervision over the memory contents and the keyboard units. Seat assignments are automatically printed, together with other pertinent information, on a boarding pass when a seat is selected.，下面是Electronic system employing plural processing stations for issuing airline boarding passes while effecting seat assignments, and generally for parcelling elements of an ordered set专利的具体信息内容。

A combination as in claim 6 further comprising a digital printer associated with each of said keyboard units, a printing module associated with said zone selector switches at each of said keyboard units, and mans for continuously maintaining said print module in a state signaled by said zone switches.
8. A combination as in claim 7 wherein each of said zone selector switches includes an output contact pair, and said print module includes a commutator and plural discrete connection positions each electrically connected to the contact pair associated with a different one of said zone selector switches.
9. A combination as in claim 6 wherein each of said keyboard units further comprise a plurality of row switches for defining a row within seating zone selected by said zone selector switches associated therewith.
10. A combination as in cliam 9 wherein each of said keyboard units further includes a plurality of seat selector switches.
11. A combination as in claim 6 wherein said central processor includes means for sequentially and cyclically polling each keyboard unit for operatively connecting the selected keyboard unit for bilateral communication with said central processor via said buss means.
12. A combination as in claim 6 wherein said display element illuminating means comprises means for generating a serial video digit stream comprising availability information for each seat within the zone of the enclosure selected by said zone switches, means for generating a serial clock byte stream, counting and decoding means at each of said keyboard units responsive to said clock pulse stream for sequentially selecting each of said keyboard unit display elements, and means for selectively activating the display element selected by said counting and decoding means in accordance with said video signal.
13. A combination as in claim 12, further comprisng counter menas for sequentially and cyclically polling said keyboard units, and means responSive to said polling means for selectively producing intermittent illumination of selected keyboard display elements.
14. A combination as in claim 13, wherein said intermittent illuminating means comprises divider means for passing selected seat availability signals to said video digit stream only during selected polling cycles.
15. A combination as in claim 14, further comprising row and seat selector switches at each said keyboard units, means for sequentially and cyclically polling each of said keyboard units, said central processor including means responsive to particular activated ones of said zone, row, and seat switches at a polled keyboard unit for interrogating said memory to determine the availability of the seat identified by said switches, and means responsive to said seat being available for allotting said seat.
16. A combination as in claim 15, wherein said central processor further comprises means responsive to a seat being allotted by said seat allotting means for changing the status of said allotted seat in said memory to an unavailable status.
