The paper proposes a solution for measuring the current consumption on the transmission lines for detecting the losses that may occur. The solution is non-invasive: the sensors determine the current by analyzing the electric field around the isolated conductor, it is fully mobile and easy to install: sensors are “clamp” type and can be placed on insulated conductors, data is transmitted wirelessly...
In this paper are presented the results regarding the simulation and the implementation of an enhanced communication interface based on pulse position modulation technique. The proposed module is aimed for integration in the conditioning circuits of the sensors that are connected to data acquisition systems which require transmission of information signals over short to moderate distances. Because...
This paper presents an acquisition system for sound recording, typical spectral component identification and extraction of particular instruments from a soundtrack, based on each instrument's spectral components. This system is also capable of sound reproduction (playback) and its main feature consists of minimizing the delay between the recorded sound and the playback sound below 100ms. To achieve...
In this paper are presented the results regarding the implementation of a communication interface dedicated for conditioning and remote transmission of measurement signals acquired from sound and vibration sensors. The interface contains two parts, an analog section, responsible with long distance signal transmission and a digital section that realize demodulation and analog-to-digital conversion...
In this paper are presented the results regarding the design and the implementation of a efficient delta encoder that is intended to be used for conditioning of signals from analogue sensors.

This article presents a “smart sound sensor” solution. More specifically it is a system on a chip capable of extracting sound patterns from an input signal captured by a microphone, patterns that correspond to certain musical instruments. The aim is to identify sounds like: voices, ambient sounds or musical sounds. Such applications generally involve the presence of a computer that analyzes offline...
This article presents a solution for tracking a mobile system using an artificial neural network. The mobile system collects data from the environment using an ultrasonic transmitter and receiver then data is processing using a binary artificial neural network. Some templates have been pre-loaded into the system to avoid blockages or additional routes. The solution is implemented on a SOC manufactured...
In this paper the authors propose a solution in which an intelligent algorithm - genetic algorithm in our case - is used to generate commands for a robot in real time, so that the robot can determine the optimal moves considering several aspects: route tracking and low power consumption. Genetic algorithms are intelligent solutions for multi-criteria optimization and using them to find solutions to...
The system presented in this paper consists of an image acquisition module from a video camera, an image processing module, which performs conversion to monochrome format, and a neural network that takes the acquired images and performs the extraction of patterns from them. The system proposed by the authors is used for recognizing the orientation of objects in real time by analyzing images from a...
The quantum computing represents a new field, which is still being researched, that may have numerous applications in the computer arithmetic, in the encryption - decryption systems, rapid search algorithms and physical systems' emulations. The hardware device that can make this type of calculations is still expensive nowadays and the number of the manufacturers is reduced. On the other hand, the...
The objective of this article is the implementation of an effective control system for a heliostat field. Each heliostat is based on a mirror and a routing system. Such a field of mirrors must be guided in order to focus the rays to a central captor device (usually placed on a tower). The efficiency of the system depends on the orientation control of mirrors on two axes (North-South and East-West)...
This paper presents a solution of design and implementation of a hardware error correction and detection circuit using associative memories. This type of memory allows search of a stored binary value, having as an input data a partial (or modified) amount of this value. This property can be used in communication, for detection and correction of errors. In our experiments the encoder just associate...
The content addressable memory (CAM) is allowed to search a data without knowing its address as to common memories. In addition, it allowed associating the content of the location or neighboring locations where the data word was identified. A problem that occurs to this type of memory is implementation complexity. A possible solution is to use a hardware implemented Hopfield neural network. This paper...
The content addressable memory (CAM) is allowed to search a data word without knowing where its address is. In addition, it is permissible to associate the content of the location or neighboring locations where the data word was identified. This paper presents our own approach for VLSI hardware implementation of the CAM memory. The proposed solution uses a Hopfield neural network model and is characterized...
