Abstract: In electronic discrimination circuitry each of a plurality of at least three analog input signals is converted to respective digital pulse output signals and to a number of multi-phase clocking signals equal in number to the plurality of input signals are also generated such that each of the plurality of at least three analog input signals is synchronized in response to a respective one of the multi-phase clocking signals, whereby at least the leading edge of each of the digital output signals is positioned into a time slot corresponding to the multi-phase clocking signals. Selected pairs of the synchronized digital output signals are sequentially compared to determine within each compared pair that digital output signal having a higher frequency and comparing that digital output signal with another digital output signal until the digital output signal having the highest frequency is selected.

Abstract: A non-contact system suitable for measuring velocity/distance of an object travelling inside a ferromagnetic pipeline utilizes magnetic dipoles written into the pipe surface by a transmission coil. These dipoles can be detected by a magnetic detector situated a fixed distance from the transmission point. If the time taken for a dipole to travel from the transmitter to the detector is recorded then this time will be proportional to the velocity of the system. The system functions both as a velocity measurement device and as a distance marker.Once the system detects a dipole it requests a further imprint, hence, a constant spacing is maintained between dipoles equal to the spacing between transmitter and detector.
