Abstract: PURPOSE:To enable to make printing out of the content of blackboard demonstration and copying of an original by one device. CONSTITUTION:When copying an original, a dial 5 is turned clockwise and a video camera 2 is set upward. An original 11 is set and a cover 12 is closed. After setting magnification of copying by operating zoom buttons 15-1, 15-2 while observing an electronic finder 14, a copy button 18 is depressed. Consequently, a video signal of the original 11 photographed by the video camera 2 is supplied to a printer 16. The printer 16 makes printing on a sheet of paper basing on the video signal, and completes copying of the original 11. When recording the content of blackboard demonstration, the dial 5 is turned counterclockwise, and the video camera 2 is set sideways. When the copy button 18 is depressed after making zoom adjustment etc., a video signal corresponding to the content of blackboard demonstration is supplied to the printer 16, and hard copying of the content of blackboard demonstration is completed.

Abstract: PURPOSE:To erase easily a part by scanning a line head sensor on a blackboard with a prescribed width to read sequentially a character or a graph drawn on the blackboard thereby inputting accurately the character or the graph CONSTITUTION:When a command of input start is received from a main control section 40, a microprocessing unit 33 drives a motor drive control section 32 and places the line head sensor 16 to the upper left part of a boad 12 Then the control section 32 drives a scan device 14 provided at one side of the blackboard and supported on a guide rail 13 is parallel with the side by driving a motor M1 in the X direction under the control of the unit 33 Moreover, a sensor support 15 is supported freely movably in the Y direction in parallel with the side in contact with one side of the blackboard based on the device 14, the motor M2 is driven and the support 15 is moed in the Y direction Thus, the image sensor 16 fitted to a support 16 is scanned in the X direction with a prescribed width on the board Further, a wiper is provided at the back of the scanning direction of the sensor 16 to attain partial erase

Abstract: PURPOSE:To prevent the generation of waiting time for recording by storing picture information read out by an optical reader temporarily in a storage circuit and recording the picture information in a recording circuit on the basis of the information stored in the storage circuit. CONSTITUTION:Characters, patterns, or the like drawn in a writing medium P and read out by an optical reader 8 and the reading signal is amplified 9 and converted into a digital signal by an A/D conversion circuit 10. The digital signal is temporarily stored in a storage circuit 11 as a writing synchronizing signal W synchronized with the winding speed of the medium P by a winding device 2, i.e. the reading speed of the reader 8 and then the contents stored in the circuit 11 are read out by regarding a signal syncrhronized with the recording speed of a recording circuit 12 as a reading synchronizing signal R. The signal is inputted to the circuit 12 and the characters, patterns or the like drawn in the paper P are recorded in paper S by the circuit 12. Thus, the contents written in the blackboard can be immediately copied.

Abstract: The use of an artificial intelligence (AI) architecture known as the blackboard model is examined as a framework for designing and building distributed systems requiring the integration of multiple cooperating expert systems (MCXS). Aerospace vehicles provide many examples of potential systems, ranging from commercial and military aircraft to spacecraft such as satellites, the Space Shuttle, and the Space Station. One such system, free-flying, spaceborne telerobots to be used in construction, servicing, inspection, and repair tasks around NASA's Space Station, is examined. The major difficulties found in designing and integrating the individual expert system components necessary to implement such a robot are outlined. The blackboard model, a general expert system architecture which seems to address many of the problems found in designing and building such a system, is discussed. A progress report on a prototype system under development called DBB (Distributed BlackBoard model) is given. The prototype will act as a testbed for investigating the feasibility, utility, and efficiency of MCXS-based designs developed under the blackboard model.

Abstract: PURPOSE:To manage effectively an electronic blackboard by constituting so that common and individual modes are switched automatically or manually as an operation mode of the blackboard, and displaying a picture filed in a storage device by the own station side only, even in the course of a conference with a remote place. CONSTITUTION:In an electronic blackboard device which is communicating with other electronic blackboard device, in case control devices 6 and 6' of both of them are set to a common mode, a handwriting information inputted in one station is superposed on a picture displaying in common and managed as a new common mode picture. While a conference is being progressed, seeing the picture displayed in common in this way, an individual mode is used in order to fetch an existing picture required for a study from a storage device and to display it. In this case, an operator inputs an individual switching instruction by a keyboard device 5, and designates a file number, etc. of the existing picture. In this way, a desired picture is displayed on a display device 4 of the own station irrespective of a display picture of the other station.

Abstract: : The use of artificial intelligence (AI) techniques for pilot aiding in real-time (DoD Pilot Associate--PA) introduces some seemingly intractable problems. Most algorithms which will be used in a PA are search intensive with exponential-order-time-co mplexities. The thesis outlines the problem and explores the possibility of using parallel processing for minimizing the computational costs. Methods for, and results from, distributing data and functions among many processors are presented. An extension to the blackboard structure used in many AI systems called a 'virtual blackboard' is introduced. The results and techniques are bundled into a prototype distributed data-flow constraint-network application system called DDAFCON. DDAFCON is discussed, and a flight-planning application is presented using DDAFCON. The results are discussed. It is shown that the maximum speedup due to parallel processing is bounded by the number of processors which a problem solution can accept. The thesis concludes that generalized AI structures and reasoning paradigms (specifically, 'deep models'), although seemingly required for the performance level desired for applications such as the PA may not be realizable for many real-time applications. A change in emphasis for developing real-time AI systems is suggested.

Abstract: Information Technology and its use in reader education has been of continual interest to Stirling University Library. In 1978, under the auspices of a British Library project investigating the potential role of intelligent terminals in libraries, we adapted a Hewlett Packard 2645A terminal to provide a ‘self‐help’ facility giving information on basic library services.

Abstract: PURPOSE:To save the power and brain of an expert by forming a system flow in the 1st step and the specifications of parts in the 2nd step at the design of software for required system specifications. CONSTITUTION:In system flow forming operation, the system flow is formed from a system flow formation knowledge 3 and an efficient system flow formation knowledge 4 (part specification retrieving knowledge). Both the formation knowledge 3, 4 are obtained by inputting know-how obtained from the expert for software design to a computer in accordance with a knowledge expression type. After ending an inference for system flow formation, the state writing the inferred result on a blackboard is held and an inference for retrieving the practical part specifications corresponding to software functional parts shown in the inferred system flow from a part data base is executed.

Abstract: Researchers are entering the second decade of research in the Blackboard problem solving framework with focus in the following areas: (1) extensions to the basic concepts implemented in AGE-1 to address, for example, reasoning with uncertain data; (2) a new architecture and development environment, BB1, that implements methods for explicity controlling the reasoning; and (3) the design of and experimentation with multiprocessor architectures using the Blackboard as an organizing framework. A summary of these efforts is presented.
