Specialized digital device for medical equipment

The ANOPS-10 is described. It is a recent version of the ANOPS series of devices developed in 1966 by the department of mathematical machines of the Warsaw Polytechnic Institute. Earlier models have already been used for several years in many biological and medical centers for investigating evoked potentials recorded from the surface of the skull or brain arising in response to external stimuli, potentials arising during cardiac and muscular activity, etc. The ANOPS-10 device serves for measurement and statistical treatment of continuous or pulsed signals, which serve as a manifestation of asynchronous activity of the investigated object (organism) or as a response to such stimuli as light, sound, electric current, etc. The ANOPS-10 is a digital device, and therefore the input analog signals are converted to digital by shaping pulses for histograms or by means of an analog-to-digital converter for averaging and correlation. Operation of the device consists in measuring the analog quantities and making calculations in conformity with the selected position of the mode selector switch. The results are sent to a ferrite storage and fed out to a built-in cathode-ray tube or can be fed out to additional external devices in an analog and digital form. The various types of output information obtainable are described, and the principal technical specifications of the device are tabulated.
