Abstract
Abstract The specification sets forth an analyser for retrieving event time information from a multi-channel graphical record sheet, comprising drive means for conveying the sheet past a linear detector device comprising a series of light sensitive elements which generate signal currents proportional to light from the chart. The drive means further includes a pulse generator for producing time base pulses in proportion to the movement of the chart and representing a predetermined time increment unit. A processor receives signals from the light sensitive devices, correlates these to each other and with the time base pulses transmits these to an output device in accordance with the desired analysis information.
