Abstract
Abstract A method employing multiple pulses per pixel to reproduce an image. A motion detector detects movement of an image receptor relative to a row of reproduction elements. The motion detector generates multiple pulses for each movement of the image receptor corresponding to a pixel dimension. Each pulse from the motion detector enables each reproduction element for a predetermined time.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A method of operating a system for rendering an image having a plurality of pixel rows, the system including N iongraphic reproduction elements, each iongraphic reproduction element being capable of receiving data and of being enabled, the method comprising the steps, performed for each pixel row, the method comprising the steps of: a first step of sending data to a first iongraphic reproduction element; a second step of sending data to a second iongraphic reproduction element, after the first sending step; an Nth step of sending data to an Nth iongraphic reproduction element, after the (N-1)th sending step; and enabling image output including substeps, each substeps performed a plurality of times per performance of the first sending step, said substeps comprising of enabling each iongraphic reproduction element at a common time, and disabling each iongraphic reproduction element at a common time, after the enabling substeps.
Claim 2
Independent Claim
145 words
A method of operating a system for rendering an image having a plurality of pixel rows, the system including N iongraphic reproduction elements, each iongraphic reproduction element being capable of receiving data and of being enabled, the method comprising the steps, performed for each pixel row, the method comprising the steps of: a first step of sending data to a first iongraphic reproduction element; a second step of sending data to a second iongraphic reproduction element, after the first sending step; an Nth step of sending data to an Nth iongraphic reproduction element, after the (N-1)th sending step; and enabling image output including substeps, each substeps performed a plurality of times per performance of the first sending step, said substeps comprising of enabling each iongraphic reproduction element at a common time, and disabling each iongraphic reproduction element at a common time, after the enabling substeps.
Claim 3
Dependent Claim
18 words
The method of claim 1, wherein the enabling step includes the substep of turning on an ion source.
Claim 4
Dependent Claim
71 words
The method of claim 1, wherein the system includes means for moving an image receptor relative to the reproduction elements, and means for detecting motion of the image receptor, relative to the reproduction elements, to generate a signal event when the image receptor moves a predetermined fraction of a pixel dimension, wherein the step of enabling image output includes the substep of receiving a signal event from the motion detecting means.
Claim 5
Dependent Claim
27 words
The method of claim 1, wherein the substep of enabling each reproduction element is performed no more than N times per performance of the first sending step.
Claim 6
Independent Claim
114 words
A system for rendering an image having a plurality of pixel rows, the system comprising: N iongraphic reproduction elements, each iongraphic reproduction element capable of receiving data and being enabled means for sending data to a first iongraphic reproduction element, sending data to a second iongraphic reproduction element after sending to the first iongraphic reproduction element, and sending data to an Nth iongraphic reproduction element after sending to the (N-1)th iongraphic reproduction element; and means for enabling image output a plurality of times per each activation of the sending means including means for enabling each iongraphic reproduction element at a common time, and means for disabling each iongraphic reproduction element at a common time.
Claim 7
Independent Claim
114 words
A system for rendering an image having a plurality of pixel rows, the system comprising: N iongraphic reproduction elements, each iongraphic reproduction element capable of receiving data and being enabled means for sending data to a first iongraphic reproduction element, sending data to a second iongraphic reproduction element after sending to the first iongraphic reproduction element, and sending data to an Nth iongraphic reproduction element after sending to the (N-1)th iongraphic reproduction element; and means for enabling image output a plurality of times per each activation of the sending means including means for enabling each iongraphic reproduction element at a common time, and means for disabling each iongraphic reproduction element at a common time.
Claim 8
Dependent Claim
30 words
The system of claim 5, wherein the enabling means includes means for turning on an ion source, and wherein the disabling means includes means for turning off the ion source.
Claim 9
Dependent Claim
68 words
The system of claim 5, further including means for moving an image receptor relative to the reproduction elements, and means for detecting motion of the image receptor, relative to the reproduction elements, to generate a signal event when the image receptor moves a predetermined fraction of a pixel dimension; wherein the means for enabling image output includes means for receiving a signal event from the motion detecting means.
Claim 10
Dependent Claim
29 words
The system of claim 5, wherein the means for enabling image output includes means for enabling image output no more than N times per activation of the sending means.
