This work deals with the practical problem of coding and control commands transmitting, as well as transmitting operating data using an ultrasonic device, which includes signal emitter and receiver. The reception scheme of low - powered signal allows extraction of information losslessly. Two ultrasonic transducers AW8T40-12OA01 and AW8R40-12OA01 (AUDIOWELL) operating at a frequency of 40.0±1.0 kHz were used as transmitter and receiver of ultrasonic vibrations. The emitter of ultrasonic radiation includes a microcontroller, a signal converter, and a transmitter. Pulses of the desired frequency are generated at the output of the microcontroller programmatically. The ultrasonic receiver includes an ULTRASONIC transducer, a two-stage amplifier, a comparator and a repeater. Transmission of values from 0 to 255 was fulfilled by using an ultrasonic signal. To simulate the process of receiving information, a switching circuit is used, in which the signal from the ultrasonic receiver is fed to the ICP input of the controller and an interrupt is used if the signal is captured. The Protocol for interaction coordination of non-volatile parts of the transceiver is developed. Two data encoding algorithms are proposed to ensure the preservation of the specified accuracy. Errors that occur during the information transmission in each case is analyzed. The ways for further development of the method and algorithm improvement are outlined. Development is carried out on the basis of the outdoor measuring complex PIKA-19, produced by LLC “Scientific and technical center PIKA-TECHNOSERVICE”.

Considered are asynchronous address and control-measurement systems using complex coded signals. This work is devoted to the analysis of indicators for performance estimation of the processing method and delay acquisition devices. The problem arises when using long code sequences in conditions of limited signal observation time and high requirements to reliability and synchronization accuracy. In these conditions use of various non-optimal methods and search algorithms, in particular, sequential-parallel search, consecutive algorithms of decision making based on a sequence segment, separate processing of components of the accepted combined sequences is limited because of decrease in energy efficiency, or complication of systems implementation. The code delay acquisition performance can be characterized by acquisition devices structure and selection of the search strategy. Also required indicators allow evaluating and comparing the performance of different initial synchronization approaches under different system parameters and channel conditions. This paper is devoted to search and analyze performance indicators of processing method and search device model that is close in energy efficiency to the optimal scheme, and also comparable to estimation of these fast conversions effectivity. It is shown that the proposed indicators are proof a gain on mean acquisition time for the offered versions of the scheme of delay acquisition. Presented results will be useful to the specialists who are engaged in design of the asynchronous-address systems using aggregate signals with large base.

The implementation of the algorithm for generating pseudo-random signals formed on the basis of the modified Lorentz system over a finite Galois field in the FPGA was considered. The received signals were matched with the previously generated method of computer simulation. The possibility of implementing pseudorandom signal generators based on the Lorentz system on relatively inexpensive and simple FPGAs is shown. The results of the work can be used to build communication systems with broadband signals, in modeling and cryptography.

The article discusses a possibility of using fiber-optic sensors based on address fiber Bragg structures (AFBS) to assess a dynamic of tire. A motivation for a study is to develop an economically sound sensor system for measuring forces acting on a wheel. A description of multisensory measurements technology of continuous monitoring of the tire state was presented and disscused. Information from the sensors is used as input parameters of algorithms that allow evaluating key characteristics, such as longitudinal and lateral friction forces. One of the advantages of this new technology is the fact that an optical photodetector is used as microwave photonic interrogator, which greatly simplifies the system.

A single scheme of klystron parameter optimization is considered, which includes structure optimization and optimization of the maximum number of input parameters (all parameters of group B). This optimization had been called as the full global optimization (FGO). Discusses two methods FGO: stage-by-stage optimization for the standard configuration of the klystron and the embedding method for the klystron configuration with higher harmonics cavities. It is shown that both methods allow reaching the level of klystron efficiency up to 90%.
