  • Apparatus for evaluating characteristics of the images of objects
    Patent number: 3976827
    Abstract: The disclosed apparatus for evaluation of characteristics of the images of objects consists of a delay unit connected to the output of a video signal discriminator, wherein the square pulses coming from the output of the discriminator of the video signal are delayed for a time necessary for effecting synchronous coincidence of the respective square pulses of the current and delayed lines of the raster of the scanning unit. The apparatus further includes a synchronous coincidence unit and a synchronous subtraction unit, each one of them being connected by its respective input to the output of the video signal discriminator both directly and through the delay unit. The output of the synchronous subtraction unit is connected to a gate connected to the output of the generator of quantizing pulses.

  • Apparatus for discriminating a peak level of a video signal
    Patent number: 3963991
    Abstract: An apparatus for discriminating a peak level of a video signal, comprising a series circuit including a switch means, a discriminator with a video signal input, and at least one video signal peak clamping channel. This channel also comprises a series circuit which includes a coincidence circuit, a pulse counter, and a digital-analog converter, the first input of said coincidence circuit being connected to the output of the discriminator, the second input being connected to the output of said switch means, and the third input being connected to a timing pulse generator. The output of the digital-analog converter is connected to the input of said switch means.

  • Method of cytological diagnostication of precancer and cancer
    Patent number: 3957034
    Abstract: A method of cytological diagnostication of precancer and cancer, which comprises obtaining cytological preparations containing cells suspected of pathology, isolating cells containing nucleoli from among the suspect cells of said preparations, classifying the cells thus selected by the number and size of the nucleoli contained therein, and diagnosing precancer or cancer by the combination of various nucleolar properties.

  • Method of cytological diagnosis of precancer conditions and cancer
    Patent number: 3955559
    Abstract: The method for cytological diagnosis for precancer conditions and cancer which consists in the fact that the coefficient of the cell size is calculated for each cell in the cytological sample from the area of the nucleus, and the area of the cytoplasm, and where the values exceeding 0.5 are selected and used to determine the mean value which serves as a criterion for diagnosing the disease.
