Abstract

A data processing system based on the concept of a neural network includes a normalizing circuit and driving elements. Each driving element has an output inductor magnetically coupled to an input inductor of the normalizing circuit. In the normalizing circuit, the input inductor is coupled to receive an input signal. The circuit also has a switching circuit responsive to the input signal and a switched inductor energized in response to the switched signal. The switched inductor comprising either a hooked or a spiral inductor.

Claims

1. A data processing system comprising:

a normalizing element having an input inductor coupled to receive an input signal, a switching circuit responsive to the input signal to generate a switched signal, and a switched inductor energized in response to the switched signal;

a plurality of driving elements, each having an output inductor magnetically coupled to the input inductor of the normalizing element; and

a plurality of driven elements, each having a driven inductor magnetically coupled to the switched inductor of the normalizing element;

wherein the normalizing element receives an aggregation of signals from the plurality of driving elements as the input signal to the input inductor.

2. A system according to claim 1, wherein the switched inductor is constructed with a spiral conductive pattern formed on a first side of an insulating body, one end of said spiral being lead through said first side to a second side of the insulating body.

3. A system according to claim 1, wherein the switched inductor is constructed with a first hooked conductive pattern formed on a first side of an insulating body, and a second hooked conductive pattern formed on a second side of the insulating body, the first and second patterns being in parallel planes, the first and second patterns connected by a conductor extending from the first pattern to the second pattern.

4. A system according to claim 1 wherein the normalizing element has an overall switching characteristic which results in energization of the switched inductor when the input signal exceeds a threshold, thereby inducing a signal in each of the driven elements.

5. A system according to claim 1 wherein at least one of the driving elements further includes an attenuation circuit attenuating the energization of the output inductor of that at least one driving element, thereby attenuating the contribution of that at least one driving element to the input signal of the normalizing element.
