Description

    TECHNICAL FIELD OF THE INVENTION
  • The present invention relates to an improved information delivery system and, more specifically, to an architecture and network that allows real time digital signals to be stored, retrieved and converted to an audio signal for radio transmission to achieve the nearly instantaneous transmission of real-time data.
    • BACKGROUND OF THE INVENTION
  • Without limiting the scope of the invention, the present invention relates to a network for gathering data and translating the data into a user-friendly format for transmission over a user-friendly medium. In such networks, emphasis is heavily placed on the accuracy of the information, the timeliness in the delivery of the information and the mode of the delivery of the information.
  • In the field pertaining to this invention, the transmitted data is airline flight arrival and departure information. In the history of scheduled passenger air transportation, it has always been a goal to get flight arrival and departure information to the public in as an efficient method as possible. In the beginning days of scheduled passenger flight, this information was generally delivered by voice and written word. Passengers would call or, if at the airport, ask an agent of the airline the time of departure or arrival of a particular flight. The information would be available either by the spoken word or a sign located within the confines of an airport.
  • Since that time and continuing to today, the passenger still gets the information the same way. Through the spoken word or through the written word. What has changed tremendously is the way the information is gathered and distributed. In the early days, the scheduling information was set by the airline and then distributed in schedule books.
  • This prior system did not address scheduling changes that occurred after the schedule book was printed. Changes could occur for any number of reasons, including delays due to weather, mechanical problems or because of changes in an airline's overall flight system.
  • The passengers would not be made aware of these changes until they entered the airport. The duty to inform the passengers fell to the agent at the airport. Overall, the prior manual system was a very inefficient system.
  • As time went on, technology began to introduce changes in the way information was gathered and distributed. With the advent of the Semi-Automated Business Research Environment (SABRE), airlines began to have a tool at their disposal that allowed them to gather information more efficiently. Today, SABRE, a computerized reservation service (CRS), and other CRS', such as Covia, Worldspan and Apollo, collect and disburse information regarding not only passenger reservation information but also flight information. These CRS' enable information to be more timely disbursed over a wide geographic area almost instantaneously. Today that geographic area includes the entire world.
  • Today's methods of conveying the scheduled flight information to passengers, include automated telephone flight information services, e-mail, facsimile, use of television screens at airports along with public address systems at individual gates. There are video monitors placed inside the airport structures. Airports also have public address systems that are used to announce the most timely of information, flight cancellations, gate changes, explanations for other nonscheduled events. Large signs have been erected at some airports that provide flight information to people entering the airports. These signs have diminished value during inclement weather because visibility is poor, making it difficult for the visiting airport person to read.
  • Accordingly, today there are various overlays of ways flight information is delivered to the airport visitor.
  • In the case of various large airports where there may be more than one airport terminal, an improved system for providing flight information prior to entering the airport facilities is needed.
  • The instant invention gathers flight information from a variety of sources, both human and computer, and converts it to a user-friendly audio signal, then transmits it to the airport visitor's automobile via radio frequencies for reception in the airport visitor's automobile. In this way, real-time information is delivered timely, accurately and in a user-friendly medium. Radio reception is not affected by weather conditions except in the most extreme of conditions. Therefore, the airport visitor has the information needed to determine where they need to go to either take or meet a flight. The radio signal is strong enough that it will reach the airport visitor's automobile prior to arriving at the airport in most instances, further providing ease of use.
    • SUMMARY OF THE INVENTION
  • The present invention is an improved flight information collection and delivery system that provides real-time information in a user-friendly format. The invention offers the advantage of delivering real-time information to the airport visitor prior to entering the airport terminal in a way that is timely, accurate and largely independent of environmental factors.
  • It is a primary advantage of the present invention to provide real-time flight information to airport visitors. This is accomplished by connecting input from a variety of sources to a virtual network. As information is gathered about a specific flight, it is fed through a network to a computerized network. The information may include expected time of arrival, departure times, flight number, gate information, etc. The computer network is a computerized reservation system (CRS). The flight information is gathered by the CRS as part of its normal operations. It is converted into a computer language that allows it to be processed by the computer and then used to do a variety of functions, including scheduling flights, assigning crews, keeping updated information on weather, etc.
  • The present invention takes this raw data in its computer language form and retrieves arrival and departure information. It should be noted that this information is the most current and comprehensive information that can be obtained about a particular flight. This information is taken from the CRS and stored on a file server. A personal computer, p.c., then accesses the file server on a periodic basis. It takes the information, retrieves and transmits it to a second p.c. that converts the computer language into a form that permits audio reception on radios. The signal is broadcast via a radio transmitter to the airport visitor. In this way, the airport visitor receives the most current information in a convenient and timely manner.
  • Another advantage of this invention is that the system will reboot itself, without human intervention and the reboot will be virtually invisible to the ultimate user. By utilizing a particular memory location and placing a bit where one was not before, the system will automatically recognize when the bit is missing. The bite will be missing when the system is not receiving information from the data storage on the file server. Monitoring the location is a background task. The background task will read that that location is empty and force a hard reading.
  • For a more complete understanding of the present invention, including its features and advantages, reference is now made to the following detailed description, taken in conjunction with the accompanying drawings.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • In the drawings:
  • FIG. 1 is a high level block diagram of a network according to one aspect of this invention;
  • FIG. 2 is a high level block diagram of the equipment that receives the data through to the transmission; and
  • FIG. 3 is a high level block flow chart of the steps the system undertakes to present the information.
    • DETAILED DESCRIPTION OF THE INVENTION
  • In the following detailed description, a user shall mean and encompass a single user, a plurality of users or anyone of a plurality of users. The word “user” shall be used to mean anyone using an airport facility. Also, a node shall be understood to mean an entry point into a network, a network element, server or other designated point of access. Other similar connotations shall be obvious to those skilled in the art upon reference to this disclosure.
  • In FIG. 1, the flight information network is shown and generally denoted as 5. Flight information network 5 is a network connected to a variety of flight information sources. The information enters through various nodes. The nodes consist of output monitors 10, printers 15, computerized reservation system (CRS) 20, and a file server 25 having a database 30. The output monitors 10 are used to output information regarding flight arrivals and departures at various locations from around the world. The flight information is sent to CRS 20 from various sources where it is stored and then transmitted out to the nodes. This information is received at an airport local area network LAN 35.
  • The information stored in the CRS 20 is delivered to the airport LAN 35 where it is then disbursed to various nodes. These nodes may include the monitors 10, the printers 15 and other output devices.
  • The present invention is a part of, and accesses, the LAN 35 to retrieve the information it needs to broadcast to the airport visitor. As previously mentioned, the LAN 35 also has a database 30 as part of a file server 25. The database 30 also captures the flight information received from the CRS 20 and culls it out from the other information. The information is held here until it is called up by personal computer 45. It is the role of personal computer 45 to receive flight information from the file server 25. Personal computer 45 takes the information retrieved from the file server 25 and converts it to an audio wave file. In the present invention, this is a typical audio wave file as developed by Microsoft. In this process, the soundblaster is initialized. The core of this function is called playwave. It first initializes the soundblaster. Then in the next step it allocates memory to receive the header information. It checks to make sure the digital signal processor is present and functioning properly. The playwave function calls all subsequent functions to the header file to read the wave. The timing loop is also set during this time. The time is set in the file server 25 from input from the CRS 20.
  • In FIG. 2, a high level block diagram of the equipment that receives the data is shown. Personal computer 45 is configured with a digital signal processor, DSP, which is 100% soundblaster compatible 16, version 4.0 or greater, with a 16 bit DMA access. Such a DSP is manufactured by Creative Labs. It is available royalty free over the Internet and needs slight customization for use with the invention. The necessary modifications are obvious to one skilled in the art.
  • The database 30 has a spelling disk 50 associated with it. Each airport has a separate and distinct city code associated with it. For example, the airport located between Dallas and Fort Worth is identified by the city code DFW. The city code of the airport at Fresno is FAT. The city code for Chicago's O'HARE field is ORD. Accordingly, one of the things the program must do is to translate the airport name from the city code into an audio wave file the name of the city that is recognizable to the user.
  • To do this a spelling disk 50 is associated with the local personal computer 45. The spelling disk uses a routine that automatically translates from city code to user language. A separate routine is required for this because the system needs to be able to differentiate between similar city names. For example, when the city San Jose is mentioned, one needs to know if this is San Jose, Calif. or San Jose, Costa Rica. Another example would be Monterrey, Calif. and Monterrey, Nuevo Leon, Mexico.
  • The same logistics encountered with the real time automated voice response system for flight information occurs here with this system. A person having ordinary skill in the art would be familiar with the work necessary to handle all the nuances that are associated with changing city codes to audible city names. Listed below is the table that is used to convert city code to audible city names.

  • The CRS 20 retrieves, stores and dispatches information about every matter concerning a flight. This information includes all take offs and landings. They are reported through the CRS 20 and then the information is dispensed throughout the system. The flight information is retrieved and stored into a database 30. This information is, in turn, be called up for use by the file server 25 in response to periodic requests from personal computer 45.
  • Because a large amount of information is received from the CRS 20, other information above and beyond arrival and departure times may also be retrieved. These enhancements would include other airline information. For example, the present invention may be used to identify not only the flight arrival time, but also the airline for which the craft is flying.
  • In another embodiment the present invention may have a continuous loop that periodically repeats the identity of the airline for whom the flight information is being provided.
  • All of this information is fed into the personal computer 45 where, as stated previously, a wave file is called up to translate the information from machine language into a user-friendly format.
  • From the personal computer 45, the information is transmitted to an audio plug 55 The audio plug 55 goes directly to a regular telephone circuit 60. The audio plug connects personal computer 45 with the airport network. The circuit may be a dedicated line or part of a vertical network. In the preferred embodiment, it is a part of a dedicated line.
  • The telephone circuit goes out to an airport LAN 63 shown at FIG. 2. The airport LAN 63 includes a radio transmitter 65 located at the airport. In the preferred embodiment the radio transmitter is a 60 watt transmitter with a broadcast radius of 10 miles. The broadcast is received on a user's radio and the user then audibly hears pertinent information regarding flight arrival and departure.
  • FIG. 3 is a high level flow chart showing the steps of the software program. In general, the program first loads the software configuration. Then it looks for and connects to the network. From the network, the software locates the file server and transfers flight information into half of a buffer. At the same time, it initializes the soundblaster and wave files and DMA. Next, it sets up the wave file and DSP. The information is then converted to an audio format and then sent to the airport LAN 63 to be sent to an equalizer 70. From the equalizer 70, the information is sent to a transmitter 65 and from there out through airport antennaes 75.
  • A copy of the source code follows. It is an embodiment of the invention but the invention should not be limited to this code. It is provided as an example.
