Filed: 1966-06-13
Abstract: 1,118,953. Selective signalling. RADIO CORPORATION OF AMERICA. 13 June, 1966 [29 June, 1965], No. 26259/66. Heading G4H. The position of a manually movable electromagnetic stylus is digitized by pulsing the stylus winding and thereby inducing positive (= 1) or negative (= 0) pulses in a pattern of pick-up windings embedded in the tablet over which the stylus can be positioned. If no output pulse results from any winding (due to the stylus inducing equal and opposite pulses which can occur for some positions) a logic circuit resolves the ambiguity by arbitrarily assigning a " zero " to the highest bit that cannot be resolved and " ones " to all the lower bits. If a pure binary output is not required a cyclic binary code can be used. A simplified logic circuit can then be used also.

Filed: 1974-06-13
Abstract: 1465293 Automatic control HITACHI Ltd 13 June 1974 [15 June 1973] 26295/74 Heading G3N An automatic working machine comprises an image input device for obtaining an optical image of a moving object and deriving electrical signals representative of the shape of the object and evaluating the signals for controlling a unit for effecting predetermined work on the object. As shown, Fig. 18, a conveyer 37 transports various articles 34-36 moving against a luminant, or illuminated, background 38. The articles are scanned by a video-camera 24 and the video signals are separated by a sampling circuit and encoded to a white 'I' or a black 'O' binary date quantizing circuit 39 before feeding to recognition circuits which are similar for each of the anticipated patterns. For each pattern, the binary signals are applied to AND gates 14" A , 14" B  enabled by a gate signal generator 13" producing a binary representation of points on a space gate signal diagram corresponding to the anticipated pattern. The outputs from the AND gates are passed through an OR gate 18" to a counter 19", the contents of which are zero when the anticipated pattern is scanned. This is recognized by a comparator 10" which initiates the operation of a manipulator 41. Fig. 20 (not shown) relates to the application of the visual information processing system to an automatic bolt tightening-loosening machine. A body 42 to be worked on is moving on a carrier in the arrowed direction and has bolts 43 separated by obstacles 44, 45. The carrier supports a plurality of bodies moving in succession and the bodies are of varied shape and size. A manipulator 51, carrying a tool 56 for tightening or loosening the bolts, is moved in synchronism with the carrier during a work-operation. Initially, a body 42 is detected by a micro switch or photocube device 42 to actuate a cylinder 48 which advances a side-face detector 49. A video-camera 50, on which the assembly 48, 49 is mounted is then advanced by a cylinder 46 until the detector engages the body which ensures that the camera 50 is at a predetermined distance. The camera 50 and associated electronics are arranged as for Fig. 18 but the manipulator incorporates a readonly memory. The Specification includes a description of the pattern-recognition techniques and the use of alternative forms of manipulator.
