Title: Measuring time span of oscillator in random sampling mode - using time measuring circuit receiving gate signal for time to be measured and gate signals of known duration
Inventor: SCHULZE WOLFGANG
IPC: G01R29/027
Filed: 1989-07-22
Abstract: The time span between a flank of a trigger signal (TR) and a flank of a gate signal, TS1, generated by a scanning signal (AT) is measured by a circuit (6) whose curve (count value per time unit) rises at a not precisely known rate. Measuring errors can thus arise. Pref., the time meaning circuit operates on the dual-slope integration principle. As well as the first gage signal, TS1, the time measuring circuit is also supplied with at least two further gate signals, TS2, TS3. The several gate signal, TS2, has a time span equal to a scanning period, a, of the scanning signal (AT). The third, TS3, has a time span equal to a multiple, pref. double the value, of the scanning period, a. The first gate signal, TS1, has a time span lying between the second and third. The exact value of the first time span is derived from three count values assigned to the time spans. ADVANTAGE - Avoids measuring errors by automatic self equalising of oscilloscope.

Title: Opto-electronic test system for PCB - has circuit detecting bores in conductor path pattern ascertained by image converter
Inventor: MAIER REINHOLD DIPL ING
IPC: G01N21/956
Filed: 1989-08-04
Abstract: The test system detects faults in conductor path patterns of p.c.b.'' with through-bore soldering eyes.  An image converter detects the conductor path pattern to be tested.  A circuit generates a serial binary image signal (bsV) from the output signal of the image converter. A fault recognition circuit (Fe) is initiated by the binary image signal.  The circuit measures the sizes of the structures ascertained by the converter and registers a fault if a preset min. value is not attained.  A circuit (SEB), with two memories (Sp1,Sp2) and correlator (Ko), detects bores in the conductor path pattern.  A fault suppression circuit (Fus)  suppresses registering (Fm) of faults that are based on measurements of the structures in radial directions directly close to a known bore. ADVANTAGE - Reliable but min. geometry measuring. Only suppresses reports of faults near bores, e.g. arising from bore edge that is too thin, but not reports of faults arising from other causes.
