2003, customer: private project, 1 developer
result: implemented, 1 installation with camera & video-board was sold
OS: Windows 98; languages: VB 6.0; tools: Win32 VfW
Adjustable motion detector of the video source. My original algorithm of motion detection uses level sensing of square and/or size of brightness and/or edge changes in selectable region. It shows windows with intermediate results (brightness difference, edges, edge changes) and sensors activity diagrams. Optional sound signaling and video activity fragment saving are provided.

Unfortunately it has only Russian interface. To use it properly expand red border of sensing region that may occasionally be collapsed to point when it is started. Read more…

1991-1992, joint project: with Production Cooperative “Informtechnika”, 1 developer
result: sold 5 boards
OS/Hardware: DOS/PC/designed ISA boar; languages: C; tools: TC 2.0, oscilloscope
Developed board grabs composite video signal with 12MHz/8bits sampling. Data was written directly to PC RAM using Master mode of ISA bus. Board had about 40 logic DIPs and fast ADC.
Grabbed composite PAL signal data is decoded by software decoder to get color picture.

1990-1991 (9 months being student), customer: Zhitomir Trunk Telephone Station, outsourcing, 1 developer
result: 1 sample was implemented and tested, they had started serial manufacturing
OS/Hardware: DOS/designed MC board; languages: Assembler i8051; tools: i8051 cross assembler
This board (for Computer controlled TTS) substitutes analog one. It detects tones of coded phone number that is passed between TTS of cities.
Prior to digital board TTS had larger percentage of errors while number detection.
Board includes i8031 MC (i51 w/o internal ROM), RAM/ROM, phone line interface with analog filter of input signal, TTS rack interface (6 logical outputs for each tone in code) and switching power unit (TTS 24V to board’s power).

1989, customer: private firm, 1 developer
result: 1 sample supplied and used
hardware: soldered controller board; languages: Assembler i8080; tools: developed at i8080 based computer
It was my first designed MC board: i8080, 2kB ROM, NO RAM (only registers of CPU), 8 digits 7-segment LED indicator, phone line interface, NO ADC (analog signal was sampled as bit stream).
Written FW: digital 6 tones caller number decoding and indicating.
