Abstract: A high density self-clocking multiple bar code is scanned to determine the displacement of adjacent leading edges of the bars and of the adjacent trailing edges of the bars. The detected leading and trailing edge displacements are compared with a standard identifiable displacement included in all of the valid codes and are categorized with respect thereto and the sequential categories thus derived define the encoded data.

Abstract: 1,236,994. Analogue multipliers. INTERNATIONAL BUSINESS MACHINES CORP. 1 Aug., 1968 [1 Sept., 1967], No. 36653/68. Heading G4G. [Also in Divisions G3 and H3- H5] An electronically variable impedance element, Fig. 2, comprises a phase reversing amplifier 5 having an input impedance, a feed-back impedance R# and an impedance 13, Rs shunting the input is characterized in that one of the impedances, e.g. transistor 13, is voltage variable in a linear manner by control signal 14. In an analogue multiplier, Fig. 10, the element 60 is arranged as a resistance which is connected to a current source 64 which constitutes one of the two signals, A, to be multiplied. The other signal, B, is constituted by source 68 which is connected to transistor 67 to control the value of resistance 60.
