Рассмотрены методы анализа пространственных характеристик непреднамеренных электромагнитных излучений, измеренных в ближней зоне средств вычислительной техники. Развитием подхода к обнаружению случайных процессов является алгоритм, основанный на оценке степени циклостационарности с использованием двумерной автокорреляционной функции измеренного сигнала. В работе проведены теоретический анализ свойств степени циклостационарности и экспериментальные исследования по обнаружению источников непреднамеренных излучений электронных устройств. Methods of analysis of spatial characteristics of unintentional electromagnetic radiation measured in the near-field of the electronic devices are considered. An improved algorithm for detecting such electromagnetic radiation is proposed. It is based on the estimation of the degree of cyclostationarity using the two-dimensional autocorrelation function of the measured signal. Theoretical analysis of the properties of the degree of cyclostationarity is performed. Experimental research on the detection of sources of unintentional radiation of electronic devices is presented.

AbstractPurposeEyemate® is a system for the continual monitoring of intraocular pressure (IOP), comprised of an intraocular sensor, and a hand-held reader device. The eyemate®-IO sensor is surgically implanted in the eye during cataract surgery. Once implanted, the sensor communicates telemetrically with the hand-held device to activate and record IOP measurements. The aim of this study was to assess the possible influence of electromagnetic radiation emitted by daily-use electronic devices on the eyemate® IOP measurements.MethodsThe eyemate®-IO sensor was placed in a plastic bag, immersed in a sterile sodium chloride solution at 0.9% and placed in a water bath at 37°C. The antenna, connected to a laptop for recording the data, was positioned at a fixed distance of 1 cm from the sensor. Approximately two hours of “quasi-continuous” measurements was recorded for the baseline and for cordless phone, smart-phone and laptop. Repeated measures ANOVA was used to compare any possible differences between the baseline and the tested devices.ResultsFor baseline measurements, the sensor maintained a steady-state. The same behavior was observed with the devices measurements during active and inactive states.ConclusionWe found no evidence of signal drifts or fluctuations associated with the tested devices, thus showing a lack of electromagnetic interference with data transmission. Patients who already have the eyemate®-IO sensor implanted, or those considering it, can be informed that the electromagnetic radiation emitted by their daily-use electronic devices does not interfere with IOP measurements made by the eyemate®-IO sensor.

Low Toxicity

This paper revises the use of polymer nanocomposites to attenuate high-energy electromagnetic radiation (HE-EMR), such as gamma radiation. As known, high-energy radiation produces drastic damage not only in facilities or electronic devices but also to life and the environment. Among the different approaches to attenuate the HE-EMR, we consider the use of compounds with a high atomic number (Z), such as lead, but as known, lead is toxic. Therefore, different works have considered low-toxicity post-transitional metal-based compounds, such as bismuth. Additionally, nanosized particles have shown higher performance to attenuate HE-EMR than those that are micro-sized. On the other hand, materials with π-conjugated systems can also play a role in spreading the energy of electrons ejected as a consequence of the interaction of HE-EMR with matter, preventing the ionization and bond scission of polymers. The different effects produced by the interactions of the matter with HE-EMR are revised. The increase of the shielding properties of lightweight, flexible, and versatile materials such as polymer-based materials can be a contribution for developing technologies to obtain more efficient materials for preventing the damage produced for the HE-EMR in different industries where it is found.
