Title: Diagnostic apparatus
IPC: A61B5/0452
Filed: 1978-08-25
Abstract: A numeric diagnostic electrocardiometer includes an A/D converter for converting an EKG signal at each of the conventional electrodes employed in EKG analysis into numbers which are stored in an assigned memory as time and amplitude signals. The waveform is divided into time segments within which the basic waveshape is known. A programmed logic array stores abnormalities within a range for each segment of the EKG waveforms. The stored samples are read into the programmed logic array and deviation of the waveform beyond that programmed produces a numeric output. The instrument may directly translate any deviation output into a readout code referenced to a suitable manual for each combination of time and sampled data. The individually stored samples may also be read out from the memory. The instrument also includes a heart rate and heart arrythmia detection units for initial analysis of the heart.

Patent ES-481182-A1 (ES)
Title: System for controlling knitting or weaving machines for the production of randomly patterned fabric
IPC: D04B15/66
Filed: 1979-06-01
Abstract: A knitting machine provided with patterning mechanisms responsive to pattern-control signals is caused to produce a non-repeating pattern by generating the pattern-control signals randomly, using a random signal generator not operating in synchronism with machine operation and generating potential pattern-control signals, from which actual pattern-control signals are derived in synchronism with machine operation. Although the pattern-control pulses are randomly generated, the overall character of the pattern produced can be altered by adjustment of the random signal generator to thereby alter the probabilities in the random generation of potential pattern-control signals. Also, pattern restraints are imposed upon the randomly produced pattern-control signals in both the horizontal and vertical directions, involving the number of consecutive stitches of a certain type that are to be permitted to adjoin in one course and in one wale, this being selectable in a manner not detracting from randomness.
