Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Computer Graphics 3D Data Converter-Projector
Computer graphics data in the form of x,y,z nodes are converted to
holographic image data which can be printed in a form suitable for three
dimensional (3D) projection.
As described in Mechanical Engineering, April 1985, pp 12 to 13, "The
Reflective Vision", an image of a three dimensional object may be broken down
into segments, e.g., polygons or nodes, and properties such as reflectance,
color, etc. recorded. For holographic images, only a grey scale of reflected light
intensity need be recorded as a property of each segment. This data is
subjected to Fourier Transformation for conversion to a holographic image.
Upon demand, the transformed data is printed on a transparent medium and, by
transmission of laser light, a virtual, 3D image is made visible. In a fashion
similar to that described in the reference, the system is completely interactive, i.e.
an operator may create images from different perspectives or make a change in
relative positions of items in an image from a computer graphics console.
Applications include, for instance, ergonomic analysis of a new set of
automobile controls by positioning a dummy or a live person to appear as a real
object in a virtual 3D holographic projection of the automobile controls.
