Mobile ECG 'Mosquito'

Device for electrocardiographic signal display on telecommunication devices "Mosquito".

The device is intended for personal use by patients and physicians - internists, cardiologists, functionalists. The main feature of the device is its compact size and low price.

For the first time in the domestic medical practice, every doctor obtained the opportunity to have his/her own pocket digital 12-channel electrocardiograph that is compatible with any phone running Android OS.

"ExpertTM-16 Compact" – radiotelemetric 16-channel electroencephalograph

Оборудование предназначено для записи и дальнейшей обработки электроэнцефалограмм в системе «10-20». Он может принимать ЭЭГ в любых условиях записи. Он не требует заземления, защиты от помех от сети 50 Гц и отсутствия изоляции помещений.
Использование цифровой телеметрии значительно облегчает долгосрочную регистрацию ЭЭГ, включая запись ночного сна, 24-часовой мониторинг и диагностику смерти головного мозга. 
 

 

LASER RADIATION WARNING SYSTEM TREDEX-LD

Timely detection of the work of laser police speed gauges (lidars) is a very difficult task for radar detectors. The beam of the laser is narrow, the algorithm of the complex is complicated, and most detectors detect its presence too late, if at all it is detected when the speed of the car is already measured and the car of the future recipient of the "happiness letter" is imprinted in the file along with a note of speeding.

EEG Cap – 16-57

Universal 16-channel EEG-cap with built-in Ag/AgCl electrodes. System10/20. 'POLINA'

The real alternative to traditional methods of EEG- registration is the universal 16-channel elastic EEG-cap with built-in Ag/AgCl electrodes.

The elastic cap outlines the head and provides tight fitting of electrodes.

The cap design is the most convenient for a patient. It doesn’t squeeze the head and doesn’t shift – each electrode is on its place during the long-term EEG-studies.

The vocoder algorithm for each pulse wave

      Modern low-speed speech codecs provide the satisfactory quality of signal transmission up to the speed of about 600 bps. High speech quality is obtained at the speed of more than 1200 bps, speeds of 200 and less are practically not used, because the intelligibility rapidly falls after the values of about 300 bps.

Design and operation experience of laser emission detection device

A.V. Kramarenko, R.V. Pavlovich

        For the lidar signal detection in a radar warning receiver (RWR) very simple design solutions like a single-limit comparator after the input amplifier are often used. Further processing is conducted with the help of the built-in processor, which uses only the values of time intervals between pulses for the analysis. It is clear that such an approach to the detection problem solving has multiple disadvantages. For example, the comparator output signal has passed a non-linear and irreversible transformation and the pulse amplitude information is lost irreversibly.

How “Telecard" works

09/26/2013
A.V.Kramarenko

Currently, our obviously underestimated estimates, by means of "Telecard" they give not less than 100 000 telemedicine consultations per year in Russia and Ukraine. Even if we assume that only one of hundreds transmitted electrocardiograms is really vital, and the probability of a correct decision on the provision of emergency assistance is 1/2, then not less than five hundred people a year do not give up the ghost or become disabled as a result of a timely remote diagnosis. Naturally, loss of the state decreases also - according to official data, about 15,000 USD per one person - a total of 15000х500=7.5 million cabbage annually.

Parametrical electrocardiographic trends compensation method

Alexander.V.Kramarenko, Yuri.A.Kramarenko, Igor.M.Gaftonyuk

In spite of the fact that some people, having read glossy ads of various firms, think that there are no problems in ECG recording, severe practice of post-soviet (and other as well) medical institutions reveal, sometimes-somewhere, the trends. Especially during Holter examinations. And they considerably hamper the medical analysis. What concerns radio monitoring systems and bedside monitors, the trend for them is especially unpleasant, as the analysis is real-time by definition. All the more the operator reacts to what he sees on the screen here and now. And when the curves are spread all over the screen or, even worse, have reached its boundaries, the situation becomes disgusting indeed.

Using geometrical symmetries for effective detection of stealth targets

06/26/2012
A.V.Kramarenko

Let us suppose that there is an idealized radio locator with the task to detect a target with the RCS approaching very small values. We suppose the noise of the locator receiver unit to be non-changeable non-zero and data accumulation when using multiple location is not permissible. We also think that the size of the target shining point is negligibly small compared to the “pencil” beam spot. The method of detection and selection of the decision making threshold are considered close to the theoretical optimum.
