Strategic points on an input waveform are selected and a continuous trace is then laid through the sequence of points by an interpolation method, known as the spline function, to reconstruct the original waveform with high fidelity. One application of the present apparatus is in the reconstruction of an electrocardiographic trace.

Method and apparatus for mathematical characterization of the

The disclosure herein describes a method and apparatus for the removal, by dialysis, of gases physically dissolved in the blood of a person, more particularly a diver or an aviator; the blood is brought into contact, in an exchange cell, with a membrane permeable to gases only; a liquid having high solubility for gases is circulated on the side of the membrane so that the gases dissolved in the blood are made to follow their chemical potential gradient across the membrane into the liquid.

Method and apparatus for the removal of gases physically dissolved by

The disclosure herein describes an apparatus and a method of analysis of line patterns such as fingerprints, ideograms, or the like, which comprises the steps of superimposing a centrosymmetric reference pattern of lines over the line pattern to be analyzed to form an interferometric pattern of the moire type, positioning the reference pattern on a characteristic element of the line pattern to be analyzed, and enlarging it until the lines of the reference pattern fill the space between adjacent lines closest to the characteristic element to thereby translate the superimposed line patterns into a field pattern of different optical densities.

There is provided a process for removing pollutant particulates from a contaminated gas which comprises:

Liquid barrier filter and method of operation

The disclosure herein describes a carrier adapted to receive observation and/or manipulation instruments; the carrier consists of a train of articulated segments whose angular displacement is controlled by a series of magnetic clutches; the leading segment is guided from the carrier's proximal end, and the guide angle is repeated automatically at the articulations of all following segments; a central channel in each segment accepts instruments for observation and manipulation. One advantageous application of the present carrier is its use as an endoscope for inspecting a hollow portion in a living body.
