SU1233191A1 - Device for selecting features in case of recognizing microobjects - Google Patents

Description

t

The invention relates to automation and computing, in particular, to devices for recognizing objects, and can be used to analyze objects consisting of microparticles, in microbiology, medicine, and other fields.

The purpose of the invention is to increase the speed of the device.

The drawing shows a block diagram of the device.

The device contains a television sensor I, a shaper of 2 read signals, a counter 3, an integrator 4, a divider 5, an indicator 6, the first 7 and a second 8 triggers, the element 9, a key 10, a group of elements And the delay element 12, the first 13 and the second 14 entrances.

The device works as follows.

Information about the number and size of the microparticles of the object under study is sensed by sensor 1, for example, a television, working in conjunction with an optical microscope and scanning the image of the object, the output signal of which is fed to the imaging unit 2, which generates pulses, the number of which corresponds to the number of object microparticles and is counted by counter 3.

The device begins to work with the arrival at the input 13 of the pulse of the beginning of the frame, according to which the trigger 7 is set to one state and opens the element AND 9, and also allows the potential for operation of the television sensor I to be resolved.

For video pulses from the sensor, Former 2 generates read signals, which pass through element And 9 to the input of counter 3. At the same time, the output signals from the driver are output to the input of Integrator 4.

As soon as the entire frame of processing information is viewed, the pulse of the end of the frame from input 14, the first trigger 7 returns to its original state, and the trigger 8 is set to one state, opening

a high potential key 10 and a group of elements AND 1I and connected to the input of the divider output.waters of the counter 3 and the integrator.

"

The divider 5 is started by a frame end pulse delayed by delay element 12 at the trigger trigger time 8. At the output of integrator 4, a signal proportional to the sum of the amplitudes of all pulses is received, and the output signal of divider 5 is proportional to the average particle size. On indicator 6, the object parameters are recognized by the values of the number and pulses (particles) and the average size of the pulses (particles).
