US Classification:

101 19

Abstract:

Hot printing of hard copy i. e. , human readable, characters to meet the strict, high quality dimensional and other standards required for automatic optical or other means of reading such characters. The printing is effected by a heat responsive ink means. In the present embodiment, the ink means is heated by the printing members. Documents, especially tags or labels, marked with such hot printed automatically readable characters. The documents may also contain punched encoded information; and may further have printed thereon conventional, human but not automatically readable characters.

Amnon Goldstein - Pelham NY

Assignee:

Advanced Technology Consortium, Inc. - Wheatley Heights NY

International Classification:

G02B 606
G03B 2700

US Classification:

385116

Abstract:

A cathode ray tube provides a two-dimensional sequential scan pattern on which dots for scanning or printing are presented as spots of light provided in sequence. A single multi-scan linear raster sweep of the cathode ray tube electron beam produces a single line of dots on the scanned image or photosensitive medium. A fiber optics array with one end facing the cathode ray tube, is configured two-dimensionally in a pattern that corresponds to the sequential sweep pattern of the cathode ray tube. The trace of dots on the cathode ray tube has sufficient length to accommodate the number of dots required for the width of the finished product or scanned image. A lens positioned between the cathode ray tube and optical fiber array, focuses the cathode ray tube image onto the fiber ends with a reduction in size. At the other end of the fiber optics array, the fibers are abutted together linearly to form the desired final output line width with coherence of the fibers from input to output. The output line width can be any desired length by abutting more optical fibers and increasing the length of the cathode ray tube sweep.

Decicom Systems, Inc. - Farmingdale NY

International Classification:

G02B 514

US Classification:

250566

Abstract:

An optical embossing reader wherein the presence of embossing at predetermined locations on a reflective plane surface is detected including means for illuminating a region of said predetermined location and light sensing means for receiving light originating from said illuminating means reflected from said reflective plane surface. The sensing means is positioned relative to the illuminating means and predetermined location for the gating by the embossing of the quantity of reflected light actually received by the sensing means if the predetermined location is embossed.

Appl. No.:

6/674620

Inventors:

David R. Spencer - Melville NY
Amnon Goldstein - Pelham NY

Assignee:

Data Recording Systems, Inc. - Melville NY

International Classification:

G01D 1514

US Classification:

346160

Abstract:

A dual mode laser printer utilizes a program-controlled microprocessor to switch between a high resolution, slow speed mode and a low resolution, high speed mode. In the printer a laser beam is modulated at a rate which is a first division of a system clock rate. This beam is caused to focus on a recording medium and, due to a rotating multi-faceted polygon, the beam sweeps across the medium. The medium is moved according to a second division of the system clock. By means of the microprocessor, the printer can be in either: (1) the high resolution mode in which the laser beam is modulated at a high rate due to the first divided signal and the medium moves at a slow rate due to the second divided signal, or (2) the low resolution mode in which the light beam is modulated at a lower rate due to the first divided signal and the medium moves at a faster rate due to the second divided signal.

Harvey Bidner - Plainview NY
Amnon Goldstein - Pelham NY

Assignee:

Bidco Inc. - Hickville NY

International Classification:

G01D 942

US Classification:

346108

Abstract:

An apparatus is provided for scanning a photographic film or the like with a laser beam. The apparatus includes a roll source or cassette of film to be supplied and used and a take-up cassette to receive the exposed film in the form of a roll. Between the source of the film and the take-up cassette there is provided an arrangement consisting of one or two knurled segments or rollers which peripherally engage the film along the lateral edges thereof in order to transport the film past a laser beam generator and scanner adjacent which the knurled roller or rollers are positioned in order to draw the film at a closely controlled rate past a slot through which the laser beam exits in order to photographically process the film. Between the knurled roller or rollers and the take-up cassette are provided exit rollers which engage the film at a slightly faster speed than the speed at which the film is travelling. The exit rollers are arranged to engage the film with a force of about 21/2-4 pounds.

Assignee:

Data Recording Systems, Inc. - Melville NY

International Classification:

G01D 1514

US Classification:

346160

Abstract:

A high resolution laser printer utilizes a first cylindrical lens to focus a laser beam in the sagittal direction prior to the facets of a rotating polygon. The light reflected from the polygon is focused in the horizontal direction at the photoconductor drum of an electrophotographic process by a scan lens assembly. Following the scan lens assembly, there is a second cylindrical lens which also focuses the laser beam in the horizontal direction at the photoconductor. The first and second cylindrical lenses are positioned to eliminate errors in the facets of the polygon. Scan velocity deviations resulting from the optical design are corrected by storing correction information in a memory and using this information to vary the rate at which the laser is modulated with data.
