Title: Character recognition apparatus
IPC: G06V30/148
Filed: 1971-09-22
Abstract: 1337159 Character recognition systems INTERNATIONAL BUSINESS MACHINES CORP 22 Sept 1971 [25 Sept 1970] 44101/71 Heading G4R A character recognition system employs a number of character segmentation units having different powers of segmentation, the output of one or other of the units being selected according to the contrast of the character. The video signal from the character scanner is fed to a store, Fig. 2 (not shown), comprising a number of shift registers each of which can store one scan line. Various cells of three adjacent registers are connected to the inputs of five segmentation units 66, 68, 70, 72, 74, Fig. 1, shown in detail in Fig. 5A-5C (not shown). The segmentation units feed respective AND gates 56, 58, 60, 62, 64, only one gate being enabled at any given instant by the output of comparator 54. A potential divider provides four signals TR1-TR4 which are proportional to the difference between a fixed absolute black level signal (2) and a signal (3) corresponding to the minimum value of a signal representing the background on which the character appears. Signals TR1-TR4 are compared in comparators 30, 32, 34, 36 with a signal V representing the running average of those video samples that are sufficiently black to have a high probability of representing a portion of the character. The comparators feed five AND gates, one of which when enabled towards the end of each scan line by clock 31 increments a corresponding counter 40, 46 etc. Comparator 54 determines which counter currently has the highest count and selects the corresponding segmentation unit, an output signal being passed to OR gate 76 when the end of the character is found. In another embodiment, Fig. 1 (not shown), the potential divider provides only one signal TR, and there are only two segmentation units, one or other unit being selected according to the sense of the count in a forward-backward counter.

Title: Frequency convertors

Filed: 1972-10-04
Abstract: 1394079 Counters V V TALOV and V G YATSUK 4 Oct 1972 45702/72 Heading G4A [Also in Divisions H2 and H3] A circuit for generating reversible sequencies of pulses on a plurality of output circuits comprises a series chain of semi-conductor switching devices 6 ... 11, the intermediate points of which connect forward and reverse windings of transformers 18 ... 23 across a D.C. supply the forward windings I ... IV being connected by a first semi-conductor switch 2 whilst the reverse windings I<SP>1</SP> ... VI<SP>1</SP> are connected via a second semi-conductor switch 3. The circuit is applicable to the generation of sequencies of pulses on output circuits X for controlling a reversible phase sequence frequency changer. As described, a pulse generator 1 feeds pulses alternately to the evennumbered thyristors 6, 8, 10 and to the oddnumbered thyristors 7, 9, 11. A change over switch 5 determines whether the sequence of output pulses shall be "forward" or "reverse". Assuming switch 5 is in the "forward" position, the first pulse from generator 1 turns on thyristor 6 which energizes transformer 4, triggering thyristor 2 which connects winding I of transformer 18 across the D.C. supply so as to generate a pulse in winding X of transformer 18. Thyristors 7 ... 11 are turned on sequentially, to provide pulses in windings X of the appropriate transformers 18 ... 23. When thyristor 11 has been turned on, a pulse is induced in winding XI of transformer 37 which bottoms transistor 36, thus turning off thyristor 6. At the end of the pulse from transformer 37, transistor 36 becomes turned off, turning off the rest of the thyristors 2, 7 ... 11. Change over switch 5 may be reversed so that thyristor 3 is turned on so as to utilize the "reverse" windings I<SP>1</SP> ... VI<SP>1</SP> of the respective transformers 18 ... 23. The sequence of pulses on the various output circuits X is thus changed.
