Putting the Mouse in Control of Computer Data Entry

Article Abstract:

The mouse was first used in 1981 by Xerox in its Star workstation as an alternative to the joystick, light pen, and other devices. Nissin Kohki has developed the OM-200 and OM-400 optical mice. Each system consists of the main unit and an acrylic sheet pad with parallel lines 0.5mm apart and one mm intervals of angles for reference. The stripes reflect ninety percent, while the spaces between them only four percent. Two optical sensors are used to detect the grid. The pad gives off infrared emissions. It uses an 8-bit processor to help in electrical signal conversion. Two to four buttons control serial or incremental output. There is an RS-232C interface. The two-button product is for office use, and the four-button for CAD-CAM. Optical mouse advantages include its ease, reliability and its lack of noise. The mouse is used with such machines as the Apple Macintosh. Three diagrams explaining its operations and two photographs are shown.

NEC Completes First Non-Neumann Computer

Article Abstract:

The NEC non-Neumann computer is a super-high speed computer system. It is currently used to process images from the Center National des Etudes Spatiales (CNES). This system represents the beginning of fifth-generation artificially intelligent computers. The computer is a ringed data drive, data flow system that uses a function type programming language. The data flow machine (DFM) consists of a control unit, main ring addresser unit and operational unit. NEDIPS (NEC Data Flow Image Processing System) has been developed to work in conjunction with the DFM. This system offers considerable cost performance. Diagrams illustrate this computer system.
