System including multiple device communications controller which coverts data received from two different customer transaction devices each using different communications protocols into a single communications protocol

Abstract: In a store data communications system, multiple data sources having disparate communications standards are connected with respective device interfaces of a multiple device communications controller unit. Multiple protocol controllers are coupled with the respective device interfaces and convert the data from each to a common protocol for transmission via a single telephone line. The interface units preferably can be customized to operate with various data sources, a fiber optic coupler, or a modem, or another controller unit for convenient expansion. The device interfaces preferably have snap-in assembly with the controller unit so that device interfaces customized to different standards can be inserted or replaced at any interface receptacle, the multiple protocol controllers preferably being capable of corresponding re-programming by downloading from a remote station preferably via one of the device interfaces.

Method for improving interactive-screen uploading of accounting data

Abstract: Method for improving the process of uploading data from a terminal computer to a host computer with interactive, data receiving screens. The method features use of spreadsheet software to format data to be uploaded in a data source file. The data to be uploaded is laid out in single-row, multi-column form within the spreadsheet so that vivid, hard copy journals of the data may be created that facilitate examination of the data and memorializes its existence. Additionally, the data layout may be transformed and provided with additional information using the spreadsheet to create the data source file having a single-column, multi-row format suitable to facilitate entry of the data to the interactive screens for uploading. Additionally, the method features use of a management program that includes instruction for directing and coordinating the feeding of the data contained the source file to an interface program that enters the data in the predetermined fields of the interactive screens.

Device for bidirectional communication on a telephone line

Abstract: An idle time communication device in which communication windows are created during the transmission of broadcast data from a center unit to a user's home device, the windows being designated to augment the data transmission function by enabling one-to-one bidirectional communication between the center and the user's home. The invention assumes the prior existence of a communication device for the transmission of broadcast data from the independent center through the telephone network to the user's home and achieves its object of one-to-one bidirectional communication between the center and the user's home through the use of packet communication which is carried out during the idle time on the telephone network, which connects the switching system of the local telephone exchange with the telephone in the user's home. The invention enables both the transmission of download data from a control unit to a specified terminal and the transmission of upload data from a specified terminal to a control unit without confusion between terminals in either case. This enables, for example, (a) a control device to transmit download data to a specified terminal and for the due arrival of the download data to be confirmed at the center by the return of upload data from the terminal, (b) the center to receive music requests and instructions in the form of upload data from a terminal, and (c) the creation of a protocol that will enable error-free communication to be carried out between the control device and terminal.

Optimal Partitioning of Data Bases across Multiple Servers in a LAN

Abstract: In 1987, Merrill Lynch was planning to establish about 450 local area networks (LANs) at its retail branch offices Attached to the LANs would be personal computers for over 10,000 retail brokers, data-base servers providing customer and product data, and communication servers for interacting with remote systems and downloading data to the local data bases The firm had not resolved how many data-base servers would be needed We partitioned the data bases across multiple servers on a single LAN and developed an analytical methodology to determine the minimum number of data-base servers needed We showed that, at most, two servers were needed for any branch office

Continuous network media server

Abstract: We are building a networked multimedia environment called Continuous Network Media Server which is based on the client-server model. The purpose of the server is to provide users with a uniform environment of multimedia where users can employ each medium or any combination of media. We have developed an experimental system of audio server to investigate problems in handung continuous media on an ordinary workstation. The experimental results show the effectiveness of our approach and highlight several problems related to current workstation technology. 1© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.

Download of an operating system over a network

Abstract: The invention relates to a method of downloading, by a server of at least one terminal comprising a volatile memory (RAM), at least one processor, a telecommunication card allowing connection of the server over a network, the said server being provided with telecommunications means and memory means of sufficient capacity to store the communications protocol, the operating system of the terminals copied into an image file, its own operating system and the application programs, characterised in that it includes a downloading procedure for a bootstrap program, consisting in converting the first interruption produced by a terminal following the application of power to it into a read request of an image file stored in memory on the server.

Electronic libraries and optical jukebox server scheduling

Abstract: The economics of large electronic libraries requires a hierarchy of storage devices, where the lowest level contains the most data and has the poorest performance characteristics. In today''s electronic library systems, this is the role of the optical jukebox. Performance obtainable from an electronic library is a function of many system and application characteristics. We are addressing performance of client/server libraries where retrieval is the primary interaction of users with the library. When the documents to be retrieved reside on the optical media managed by the jukebox server, and nowhere else in the hierarchy, then the retrieval of these documents becomes a batch task. This is acceptable for many users and applications environments: for professionals who are simultaneously at various stages of many tasks and can anticipate the next ones, and for clerical workers in an environment controlled by work- flow (and not interrupt driven). Scheduling of batch retrievals of documents from archival storage need not be in the same order as requests. This paper proposes a cyclic scheduling for retrieval of documents from the optical jukebox, and shows by simulation that this cyclic scheduling can offer significant performance improvement over that obtained by FCFS scheduling of the jukebox.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.

Method for automating up-loading of help panel and method for automating record transfer

Abstract: PURPOSE: To provide an upload processing automatizing method for help panel in a data processing system. CONSTITUTION: A cluster or virtual storage access methods is assigned and installed to a client information control system area (CICS) which executes office vision/multiple virtual storage (OV/MVS), thereby generating a multiple virtual storage (MVS) environment. The help panel built up AS a batch file of a personal computer (PC) 12 is uploaded and is held in a temporary storage area in the OV/MVS. The PC batch file is taken out from the temporary storage area by using OV/MVS facilities and is converted into an MVS format file. The converted file is held in a special save area. The converted PC file in the save area us used as help panel index data to generate a shared document.

Development of a coded-image document station with a capacity of 300,000 pages and accessible from remote terminals via ISDN

Abstract: We have developed a document station for automated entry and remote retrieval of image documents, and we present experimental results on remote retrieval via an integrated services digital network (ISDN). The document station consist of a UNIX workstation, a 130 mm rewritable magneto-optical disk subsystem, a code/decode board, character-recognition hardware, and a high-speed image scanner. This station can store 300,000 black-and-white A4 pages at 5.0 seconds per page. The experimentally measured time for retrieving one page at a remote terminal is 1.5 seconds within a 10 Mbps local-area network (LAN) and 2.0 seconds within a 1.5 Mbps ISDN.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
