DEVICE FOR READING OUT GRAPHIC INFORMATION Russian patent published in 1994 - IPC

Abstract RU 2015566 C1

FIELD: automatics; computer technology. SUBSTANCE: device may be used in systems of automated coding of images. Electromagnetic field, which is excited in the device, rotates in horizontal plane due to corresponding energization of two inverse orthogonal inductance coils. Coordinates are read out, when signal with zero derivative is detected in the remover. EFFECT: improved precision of the device. 2 cl, 4 dwg
