Abstract
Abstract The present invention refers to a digital anode that permits capturing electrons and digitalizing their location on a given surface, so that it can be stored in a memory to be later processed and either interpreted, printed, filtered or transferred.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
A digital anode that enables the capture of electrons on a given surface and permits to know their precise location by digitalizing their position in a system of cartesian coordinates, said digital anode comprising a plurality of electronic transducers that have a given initial voltage and a different voltage value when they have captured electrons, said transducers being interconnected, in a system of cartesian coordinates, by horizontal and vertical lines, said lines being directly connected to decoding electronic circuits that furnish the position of said electrons substantially simultaneously upon said capturing of said electrons by said transducers.
Claim 2
Dependent Claim
97 words
A digital anode that enables the capture of electrons on a given surface and permits to know their precise location by digitalizing their position in a system of cartesian coordinates, said digital anode comprising a plurality of electronic transducers that have a given initial voltage and a different voltage value when they have captured electrons, said transducers being interconnected, in a system of cartesian coordinates, by horizontal and vertical lines, said lines being directly connected to decoding electronic circuits that furnish the position of said electrons substantially simultaneously upon said capturing of said electrons by said transducers.
Claim 3
Dependent Claim
38 words
A digital anode as recited in claim 1, wherein the input voltage varies within a range of, from 45% to 95% of the voltage of the transducer itself and wherein the output voltage responds to on/off electrical signal.
Claim 4
Dependent Claim
25 words
A digital anode as recited in claim 1, wherein the decoding electronic circuits are connected to yield information in a binary, analogic or decimal form.
