We build wearable devices, home health devices, and devices for the aging, among others. My staff of engineers and I are experienced with:

  • Medical devices — we have a Design Control procedure meeting FDA 21CFR 820.30 and ISO 13485:2003
  • Wireless: Bluetooth, WiFi, Zigbee, cellular (CDMA, GPRS, GSM), GPS, NFC, and RFID
  • Sensors like temperature, pressure, accelerometers, gyroscopes, magnetometers, strain, vision
  • Sensor signal conditioning, analog-to-digital converters (ADCs), and low power
  • Batteries and power conservation
  • FPGA and CPLD: Altera and Xilinx using Quartus, ISE, ModelSim, VHDL, and Verilog tools
  • Embedded design: microprocessors (Intel, Renesas, PIC, Freescale, ARM, etc.)
  • Communication such as USB, Ethernet, RS-232, and RS-485
  • Software using Linux and Windows operating systems
  • Microsoft C (C++, C#, and .NET), Java, and Visual Basic
  • Embedded software including board support and drivers in Linux
  • Motion control systems: stepper motors, servo motors, and AC motors
  • Analog circuit design: low current (picoamps) and high speed (over 100 MHz)
  • Power supplies, including switching regulators
  • Complete product development including design, PCB layout, prototype testing, and transfer to manufacturing
  • Data acquisition systems
  • Test equipment


Ours is the highest quality work, done by professionals. Recent examples of our work:

  • Wearable golf game tracking device
  • Wearable night vision device
  • Sterilizer for home dialysis
  • Passive monitor for the elderly
  • Stroke therapy machine including sensor signal conditioning and motion control
  • Tester for heart ablation catheter
  • Heart pump


Comments by clients:

  • It was on time and below budget.
  • Excellent job
  • Their work is professionally done, high quality, and on time.
  • They worked well under pressure and cooperated well


Outstanding references available.
