Portable data file readers
First Claim
Patent Images
1. A process for receiving an image of an object, comprising:
- (a) aiming one or more beams of photons at the object;
(b) capturing an image of the object for preprocessing;
(c) determining whether the object is within focal range;
(d) focusing the image upon two or more photosensitive arrays, wherein the step of focusing involves adjusting two or more lenses such that a partial image of the object is focused on each array, wherein the partial images overlap each other;
(e) indicating whether the object is within focal range;
(f) controlling the exposure of the object;
(g) triggering the capture of the image;
(h) capturing a partial image by each of the arrays;
(i) digitizing said captured partial images; and
(j) processing said captured partial images.

18. A portable reader of images from objects, comprising:
-
(a) a frame having a window; (b) at least two photosensitive arrays mounted within said frame and behind said window, said array for converting images into corresponding electrical signals; (c) at least a adjustable two optical strings between said frame window and said arrays for focusing a partial image of an object onto each array;
wherein the partial images overlap each other;(d) at least two electromagnetic beam generators mounted on said frame such that the beams of said generators cross near the point of best focus of said optical strings; and (e) computer means for processing said electrical signals from said arrays. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A portable reader of images from objects, comprising:
-
(a) a first two-dimensional sensor array and a second two-dimensional sensor array; (b) a first optical lens and a second optical lens, said first optical lens moveable relative to the optical axis of said first sensor array, and said second optical lens moveable relative to the optical axis of said second sensor array; (c) means for reciprocating said first and second optical lenses relative to their respective sensor arrays such that a partial image of an object can be focused on each array wherein the partial images overlap each other; and (d) means for accurately positioning the portable image reader relative to an object to be read. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A process for receiving an image of an object, comprising:
-
(a) aiming one or more beams of photons at the object; (b) capturing an image of the object for preprocessing; (c) determining whether the object is within focal range; (d) focusing overlapping partial images of the object upon two or more photosensitive arrays each of said arrays having an optical axis of sight, wherein the step of focusing involves shifting the optical axes of sight depending upon the distance of the object from the arrays such that the overlap of the partial images remains a substantially constant percentage of the total image; (e) indicating whether the object is within focal range; (f) controlling the exposure of the object; (g) triggering the capture of the image; (h) capturing a partial image by each of the arrays; (i) digitizing said captured partial images; and (j) processing said captured partial images.
