摘要： A method of measuring the twist imparted to an optical fibre includes the steps of advancing the optical fibre in a predetermined direction and at a predetermined velocity, imparting to the optical fibre, during the step of advancing, a twist about its axis, measuring the diameter of the optical fibre during the step of advancing, to generate a time-based signal indicating the diameter, and processing this signal to find a value indicating the imparted twist. The step of processing includes the principal steps of transforming in the frequency domain the signal relating to the measurement of the diameter, calculating the power spectrum of the signal thus obtained, distinguishing in this power spectrum the signal peaks correlated with the imparted twist, determining the maximum frequency associated with these signal peaks, and dividing the value of this maximum frequency by the value of the velocity of advance of the fibre to find the value indicating the imparted twist.

摘要： An object measuring apparatus for measuring the dimensions of an object, and controlling the pushing pressure of a probe that makes contact with the measured object. A table is movably mounted on a base member, a drive unit includes armature coils on the base member and a field magnet on the table, and a probe is fastened to the table and driven along the base member by the drive unit. A linear magnetic scale is provided on the base member, and a magnetic sensor portion is provided on the table. A measuring position detection sensor on the probe detects the object to be measured. An output from the measuring position detection sensor indicating that an object has been detected, and the pulse output generated by relative movement of the sensor portion and the scale, are supplied to a processing unit to calculate the dimensions of the object. The thrust of the probe is nearly proportional to the drive current supplied to the armature coils, so that the thrust of the probe unit can be controlled before determining the dimensions of the object.

摘要： In the continuous measurement and control of deviations in cross-section of slivers with constant relative sensitivity which is independent of the adjusted set value with respect to this set value, the sliver is guided between a grooved roller and a feeler roller which contact each other in the absence of the sliver between the grooved roller and the feeler roller. The changes in the position of the feeler roller are converted into rotational movements of a lever shaft and thus into changes of direction of a measuring tab. The measuring tab is arranged eccentrically on the lever shaft.A sensor is movable by means of a lead spindle which is perpendicular to the lever shaft and lies in a plane determined by the lever shaft and by the axis of the feeler roller in the absence of sliver between the rollers. This sensor preferably has a magneto-resistor. The changes in direction of the measuring tab are, therefore, transformed into fault signals of the magneto-resistor, the fault signals being used to control the thickness of the sliver.

摘要： Measurement devices and methods for measuring balloon catheters are provided. Embodiments enable measuring the outer dimensions and burst pressure of a balloon catheter. The measurement apparatus can measure a balloon catheter in ambient air or a balloon catheter submerged in a heated water bath. In ambient air, an axial drive mechanism translates the balloon catheter in an axial direction and a rotary drive mechanism rotates the balloon catheter while a measurement device is used to measure balloon catheter dimensions. In a water tank, an axial drive mechanism translates the balloon catheter in an axial direction while a measurement device is used to measure the burst pressure of the balloon catheter. The devices and methods can utilize a laser micrometer in order to provide such measurements. A control unit provides a user interface and is capable of displaying real time data during the measurement process.
