Voler Systems specializes in medical devices, sensors, motion control, and wireless communication. We build wearable devices, home health devices, and devices for the aging, among others. My staff of senior engineers and I can design a new product rapidly that works the first time. We 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
