IPC: G01P5/00
Filed: 1990-06-28
Abstract: ABSTRACT OF THE DISCLOSURE         Pulses of an ultrasonic wave beam are emitted into a body at a predetermined repetition period.  Echo pulses of the ultrasonic wave beam are received via a plurality of different channels.  Each of the received pulses is converted into corresponding electric signals of the respective channels.  A pair of adders invert signs of alternate ones of pairs of the electric signals of adjacent channels, summing the inverted sign electric signals with remaining non-inverted sign electric signals, converting the electric signals into a pair of complex signals having phases which are spatially different from each other by 90 degrees.  An autocorrelation function of the complex signals is calculated.  A component of a speed of moving matter within the body in a predetermined direction is calculated on the basis of the autocorrelation function.          The moving matter causes the echo pulses.  The predetermined direction is perpendicular to a direction of travel of the ultrasonic wave beam pulses.

Abstract: An optical fiber cable core (20) which is sold to a cable manufacturer for oversheathing or for incorporation into electrical power aerial cables, for example, includes in a preferred emdobiment at least one bundle (23) of optical fibers (25-25). The at least one bundle is disposed in a tubular member (30) which is made of a plastic material suitable for use in relatively wide temperature range. The core is manufactured to cause a predetermined excess length of fiber to be disposed in the tubular member. The excess length of each fiber is such that it is sufficient to avoid undue strains on the fiber as the cable core is exposed to the elements and to forces imparted during handling such as during installation. On the other hand, the excess fiber length must not be so great as to result in undue curvature of the fiber or excessive interactive engagement of the fiber with an inner wall of the tubular member. Also, the plastic material of the tubular member must be such that it responds linearly to the application of tensile forces up to a strain corresponding to the excess fiber length at a given temperature.
