Display system

A situational display and a means for creating the display are disclosed. The display comprises a moving line or raster, on a cathode ray tube, which is disposed intermediate of two columns of lamps or intensifications on the cathode ray tube. The raster and lights are controlled in such a manner that pairs of lights define a line which is either tracked or chased by the raster in accordance with the relationship between the optimum and actual values of a monitored parameter

Digital video display system

System displays image data in real time on 120,000-element raster scan with 2, 4, or 8 shades of grey. Designed for displaying planetary range Doppler data, system can be used for X-Y plotting, displaying alphanumerics, and providing image animation

Credit card display system

A card-oriented transaction system (10) is provided with the capability of communicating with the card user. Specifically, the system is provided with a user card (11) having a surface region (13) capable of receiving an erasable visual image, a card reader (14) capable of detecting the card and writing on the display surface, and a data processor (16) adapted for providing information to be written on the display surface. In a preferred embodiment, the erasable visual display surface (13) is a plastic film embedding droplets of oil containing reflecting magnetic flakes. The film can be laminated onto the user card and reset by a magnetic field in the plane of the major surface. Writing can be effected by application of a magnetic field perpendicular to the surface.Published versio

Stereoscopic computer graphics display system

Handbook was published on study which describes relative merits of two general-purpose, steroscopic display systems. Both systems are adaptable to most small data processing facilities and, with minimal hardware development, greatly enhance user ability to interact with computer and to interpret data output. Section also describes digital-to-analog converters designed for use with system

System status display information

The system Status Display is an electronic display system which provides the flight crew with enhanced capabilities for monitoring and managing aircraft systems. Guidelines for the design of the electronic system displays were established. The technical approach involved the application of a system engineering approach to the design of candidate displays and the evaluation of a Hernative concepts by part-task simulation. The system engineering and selection of candidate displays are covered

Image display system 511

The experience of the Idaho Department of Water Resources Remote Sensing Unit in bringing on line their System 511 is described. The system 511 is run on a PDP minicomputer. The minimum system hardware configuration is an 11/34 with a minimum core of 128 K word, 10 megabytes of direct access disk and a floating point processor. The required software configuration is an RSX 11M V 3.2 operating system with a FORTRAN IV plus compiler. The structure of System 511 is a series of hierarchical modular software units. Problems occurring during the systems installation are discussed, and the system operating and error detection capabilities and documentation evaluated

What does augmented reality mean as a medium of expression for computational artists?

As augmented reality (AR) quickly evolves with new technological practice, there is a growing need to question and reevaluate its potential as a medium for creative expression. The authors discuss AR within computational art, framed within AR as a medium, AR aesthetics and applications. The Forum for Augmented Reality Immersive Instruments (ARImI), a two-day event on AR, highlights both possibilities and fundamental concerns for continuing artworks in this field, including visual bias, sensory modalities, interactivity and performativity. The authors offer a new AR definition as real-time computationally mediated perception

Electric field measuring and display system

An apparatus is described for monitoring the electric fields of cloud formations within a particular area. It utilizes capacitor plates that are alternately shielded from the clouds for generating an alternating signal corresponding to the intensity of the electric field of the clouds. A synchronizing signal is produced for controlling sampling of the alternating signal. Such samplings are fed through a filter and converted by an analogue to digital converter into digital form and subsequently fed to a transmitter for transmission to the control station for recording

Synchronized voltage contrast display analysis system

An apparatus and method for comparing internal voltage potentials of first and second operating electronic components such as large scale integrated circuits (LSI's) in which voltage differentials are visually identified via an appropriate display means are described. More particularly, in a first embodiment of the invention a first and second scanning electron microscope (SEM) are configured to scan a first and second operating electronic component respectively. The scan pattern of the second SEM is synchronized to that of the first SEM so that both simultaneously scan corresponding portions of the two operating electronic components. Video signals from each SEM corresponding to secondary electron signals generated as a result of a primary electron beam intersecting each operating electronic component in accordance with a predetermined scan pattern are provided to a video mixer and color encoder

Contourograph display system for monitoring electrocardiograms

Electrocardiogram is displayed as a contourogram on the cathode ray tube of a variable-persistence oscilloscope. Each cycle is stacked below its predecessors giving a three dimensional effect. A major change in the signal is apparent as a change in the contourogram pattern
