Abstract

This pneumatic multiplication matrix has a plurality of overlying inflatable elements x, y, o. In A and the enlarged fragmentary view B, all elements x are parallel and extend in an X direction within one plane. All elements y are parallel and extend in a Y direction and lie in a plane below the X plane. All elements o are parallel to each other and extend at oblique angles through the points of intersection of different ones of the x and y elements and lie in a plane between the planes of the x and y elements.

Pneumatic Multiplication Matrix

This pneumatic multiplication matrix has a plurality of overlying inflatable elements x, y, o. In A and the enlarged fragmentary view B, all elements x are parallel and extend in an X direction within one plane. All elements y are parallel and extend in a Y direction and lie in a plane below the X plane. All elements o are parallel to each other and extend at oblique angles through the points of intersection of different ones of the x and y elements and lie in a plane between the planes of the x and y elements.

Elements x and y are input lines. Elements o are output lines. Pressure fluid normally flows through each output o. If pressure fluid is supplied concurrently to any x and y input elements, these elements expand and, at their point of intersection, exert a pinching force on the output element o passing through that coordinate point. This pinches off flow through such output element o. Such produces an output signal corresponding to the product of the assigned values of the two concurrently pulsed x and y input lines.

For example, if binarily weighted input lines x-4 and y-8 are concurrently charged with pressure fluid, they pinch off flow through output o-32, denoting a product of 32. If input lines x-4 and y-8 and also y-2 are concurrently pulsed, then outputs o-32 and o-8 are pinched off concurrently. In this case suitable devices (not shown) are employed to add these products to give a total output indication of 40. With...
