Main target of this project is to create own implementation of mesh network environment and provide 3rd party API for applications to communicate in this network. One part of this project is to implement mesh network using ad-hoc Wi-Fi connection capability of Android based mobile phones. To enable ad-hoc Wi-Fi communication, we had to modify existing android kernels and Wi-Fi chipset drivers. Implementation on Android platform consists of modified Wi-Fi chipset drivers, daemon written in native code that handles our specific network protocol and routing, higher level service written in java for interfacing daemon to user level applications and 3rd party java API library that uses our specific sockets to run communication. IOS implementation due to IOS API limitations consists of application with integrated daemon code and can only act as our mesh network node when in active state. Beside Android and IOS implementations, our mesh network runs on standalone Linux based routers (Mesh Network Routers) that extend network coverage. Daemon code is written in C/C++ and is portable to any Linux based device.

To implement flexible mesh network node we created custom Linux based device that has two independent Wi-Fi chips onboard. This is required to have both Ad-hoc and Access Point interfaces at the same time and allows both types of clients to connect simultaneously

Core project for our extension boards consists of media switches connected by high speed optical communication channels, media management software and extension boards that can be installed in media switches to convert typical media signal (SDI, Analog Video, Audio, etc.) to special internal digital format. After conversion digital data is transmitted over high speed digital optical communication channel to another media switch where it is again converted to normal media format and routed to desired destination.
Our scope for this project included development of two extension boards: 4 channel Analog Video In and 4 channel Analog Video Out. Schematics were created in Mentor Graphics DxDesigner, PCB was created in Mentor Graphics PADS and signal integrity and crosstalk simulated in HyperLynx. VHDL code for Virtex-2 Pro was also fully created by us in Xilinx ISE. Two stages of prototypes were produced on AT&S factory (Austria) and second prototype passed certification tests (signal quality) as professional video broadcasting equipment. As far as we know, later this boards were used by ORF (Austrian Broadcasting) and some more widely known broadcasting companies.

This project consists of two types of devices (Hubs and Sensors), server side that stores sensor data and mobile applications that show data to user. Hub serves as gateway for sensor data to our cloud service. It has capability to connect to internet using Wi-Fi or 3G/4G and if working offline it can temporarily store sensor data on SD card. Sensors can operate in wired mode being connected directly to Hub or can be connected wirelessly using 2.4 GHz 802.15.4 interface. Functionality of Sensors can be extended by connecting External Sensors to special port on sensor board. This External Sensors are also MCU based and provide plug and play capability. Both Hubs and Sensors can be powered from external power source or use internal rechargeable battery. Sensor schematics are optimized for power efficiency and can wirelessly work for years from a single charge (depends on activity).

Extension board for Beaglebone Black that adds Wi-Fi and IEEE 802.15.4 radio (ZigBee, BLE, etc.) functionality. Board is designed for 1.8V to skip level convertors and deliver maximum communication speed over SDIO between host CPU and Wi-Fi module. To achieve this Beaglebone board that was initially designed for 3.3V also needs some modifications.

Task was to create framework that is capable of creating virtual USB devices (like virtual flash drive, or Bluetooth, or Wi-Fi) and connecting them to system by adding a virtual USB hub device and attaching all this virtual devices to this hub. Beside the functionality we had to provide simple and easy to use API for 3rd party developers for making this virtual USB devices. This project was a part of bigger project that was aiming to make USB device sharing over network.

This is application test environment created for one specific application which is interfacing with multiple hardware devices (up to 32). Application itself had requirement to be launched in up to 20 copies on the same machine via terminals. Human quality assurance with this amount of devices and windows is very hard to implement and regression testing takes too much time. Task was to create virtual environment including desktop and all other operating system resources, and also create virtual devices to which application will connect, in this virtual environment. When launched, application was tested with some pre-defined scenarios which included random factor, virtual device were connecting, disconnecting, operation errors were simulated and finally report was created on the functionality of new version.

This is a full cycle product which includes all stages of development and production (design, schematics, PCB, embedded software, embedded service loaders, PC drivers, PC software, supporting internet site and application server). Target task was to provide aftermarket service solution for popular mobile phone brands. Product was mostly used in phone repair shops who service phones with expired warranty, and by some genuine service companies in case were official service support was not enough to fix the problem. Product consists of device which is connected to PC via USB, a set off cables to connect this device to mobile phone, PC software and our server access account for software updates and some server dependent calculation procedures.

This was written in C/C++ highly optimized internet server that was serving application specific data and using own HTTP / SSL protocol implementation. Task was to use technologies that allowed this server to be configured to run both on windows and on Linux, and another key point was that this server had to work with USB security device, which also had to work on both operating systems.

Device driver that is capable of intercepting operating system writes to persistent storage and substituting data. This was used to make fake changes to some hard disk sectors and protect original data from being overwritten. This project was part of bigger project that was aiming to make hard drive optimization utility for SSD drives.

Task was to create in-expensive solution for monitoring 4 channels of high speed digital signals (up to 400 MHz). It was implemented as PCI board with FPGA (Xilinx Spartan) and custom probe with integrated CPLD for multi-point sampling. We developed FPGA and CPLD firmware using Xilinx ISE in VHDL language and for the PC operating system side we developed driver and end user software.

The goal of development is to adapt series of 12 watt power supplies to fulfill upcoming EMC and efficiency standards. The customer was a big manufacturer of power supplies and inductive components. This power supply should pass all existing requirements in the globe for consumer and medical equipment including all ranges of AC mains voltage, existing and upcoming wired and wireless EMC, power efficiency, safety, ESD withstand and humidity standards. The schematic is based onNCP1219 PWM controller and operates in flyback topology. All parts of schematic was redesigned and optimized for high volume production. Special care was taken to design and tune transformer as primary source of efficiency and EMC problems. Series of transformers was designed and optimized to support any voltages in range from 5 to 24V. Deep analyzing was made in temperature of every part of PCB in full load in all configurations. A lot of EMC and efficiency testing was made. Over 500 experiments was made to get the best quality/cost result.
