EXAMPLES OF PROJECTS:
 
  • Automated Vehicle Localisation Device (Prototype of Invention)
An example of Proof-of-Concept development. Vehicle Location Device with Bluetooth 2.0. Most interesting feature is providing, via Bluetooth, the Internet access for Tablet.Hardware based on Raspberry PI 2B with GPS, Bluetooth and LTE module. Designed and developed software for Raspbian Linux. Developed Android Application, according to requirements, in order to evaluate and demonstrate prototype\'s features.
Used Technologies: Bluetooth, LTE, GPS, SMS
  • Bluetooth Smart interface for Coffee Machines
Wireless interface for Coffee Machine which allows Mobile Application to start and show progress of products as well as statistics reading and maintenance status. Added support of accessories based on legacy 2,4GHz radio protocol (Milk Container). Developed firmware for nRF51 chip. Up to 6 wireless accessories can be supported simultaneously. Concurrency operation of proprietary 2,4 GHz protocol (accessories) and Bluetooth Smart (Mobile App). Developed test software to evaluate and demonstrate features.
Used Technologies: Bluetooth Smart, 2,4GHz RF, nRF51
  • Bluetooth Mobile Gateway for telemedicine and homecare applications.
Developed firmware and application of the Gateway for tele-diagnosis. The Gateway takes advantage of BGS2 wireless M2M module to access the Internet. Following technologies have been used: HTTPS, RESTful, JSON, LZMA in order to communicate with a server. The Gateway readouts data wirelessly via Bluetooth protocol (Class II) from medical devices. Whole customer\'s configuration (e.g schedule, MAC address of allowed medical devices) is kept in cloud database including firmware upgrade.
Used Technology: GSM, Bluetooht, ARM, WiFi, HTTPS, RESTful, JSON, LZMA
  • NCR-270
Easy to use card reader that allows the drivers to provide securely their Digital Tacho Card data to the headquarters office form any place in EU.ISO 7816-3, ISO 7816-4 standards for Tachograph Card Application Protocol implemented on Cortex-M3 microprocessor. NCR-270 takes advantage of TC65i wireless M2M module to access the Internet. Due to e-mail protocol has been implemented customer can use his existing facilities or free e-mail services. Secure data transmission has been achieved by using SSL security protocol. Developed Java Swing application which allows to configure and monitor NCR-270 devices via USB (HID) as well as over air.
Used Technologies: SMTP, SSL, GSM, ISO 7816-3 / 4, USB HID
  • NRE-104 (GN10)
Complete design and development firmware based on STM CortexM3. NRE-104 is a light terminal with GPS/GLONASS and GSM connectivity, which is able to get device coordinates and other data and transfer them via cellular network. The most interesting features include support for CAN bus of many types of vehicles including trucks and engineering vehicles, USB and over air firmware upgrade, an innovative communication protocol with server. Equipped device with GPS (uBlox LEA6) and GSM (TC65i) module, accelerometer and a lot of interfaces which allow to read/send data from I/Os, CAN, RS-485, 1-wire, I2C, FMS, OBDII. Added support to plenty types of sensors like fuel-level, distance, rpm, temperature, driver identity, flow measurement etc. Implemented advanced algorithms for flash-memory data storage, fuel-level measurement, collision detection and eco-driving. Developed Visual Basic application which allows to configure and monitor NRE-101 devices via USB (COM) as well as over air (GPRS). Manufactured around 7,000 units in 4 years and provided after-sales service and maintenance.
Used Technologies: GPS, CAN, FMS, RS-485, GPRS, 1-wire, ARM
