.~ Computational system employing liquid crystal element (neural network, correlation device, optical computer)
DEFINITION
Classification: 349/17
Computational system employing liquid crystal element (neural network, correlation device, optical computer):
(under subclass 1) Subject matter wherein liquid crystal cells are utilized to optically perform basic or more complex mathematical processes such as comparing, adding, subtracting, correlating, adaptive algorithms or neural network type algorithms.
(1) Note. Excluded from this subclass are liquid crystal elements merely employed as memory storage for a computer and the mathematics inherent to any optical process. For such excluded subject matter, see SEARCH CLASS below.
