I have deep knowledge and extensive experience in developing of Embedded Systems (expert level): - Measuring systems: - Detecting and processing information from motion sensors, temperature, vibration, and other physical parameters; - Circuit design for measuring electrical signals in the frequency range from zero (direct current) to ultra-high frequencies; - Software design of interfaces for control / measuring systems based on personal computers (using Visual Studio); - Control systems: - Development of Signal Processing algorithms based on spectral, correlation analysis, digital filters, etc. - Development of control algorithms for actuators, including based on electric motors of any type; - Deep knowledge and extensive experience in the design of power electronics with microcontroller control: - Motor drivers (frequency regulators); - Pulse battery chargers (Pb, Li-Poly, Li-Ion), including BMS; - Uninterruptible power supplies (UPS); - Switching power supplies, etc. 2. I have deep knowledge and wide experience in the design of microwave radars - systems for detecting physical objects (expert level): - Proximity fuses; - Detection of moving objects with super-small reflection of microwaves; - Penetration detectors in the protected territory (microwave sensors of intruder alarm), etc. Currently, I develop microwave radar for detecting static objects (for example, for accident prevention systems at railway crossings). 3. I have deep knowledge and wide experience in the design of microwave oscillators based on Gunn diodes and autodyne transceivers (expert level). 4. I am fluent in working with measuring equipment. 5. I am the author of approx. 20 scientific papers about generation and reception of microwave oscillations, including 3 Inventor's certificates and 1 USSR patent. Greatest interest is the invention of super-high-sensitive microwave radar. 6. I use software tools in my work: MATLAB / Simulink, IAR Embedded Workbench, Proteus, Altium Designer, PCAD, CorelDraw, AutoCAD, VisualStudio, MPLAB X IDE, Adobe Audition, MS Office, etc. 7. I work with controllers: Microchip (8-bit), Texas Instruments (16 bit, ARM), ST Microelectronics (ARM). Experience with microcontrollers - since 1996. Previously I worked with Intel 8080 microprocessors (in 1984 - 1990). less
