Heartstream
XLT Defibrillator, 1998-2000 System and main controller design. Overall product validation, test, and regulatory qualification testing. This was the last product designed by the resuscitation group of Agilent Technologies (previously Hewlett Packard, now Philips) in McMinnville, OR. |

Heart Sound Detection Algorithm, 2001-2003 I developed the heart sound detection algorithm used in the Inovise Audicor product. This was an extensive DSP algorithm project that involved data collection, biomedical research and sensitivity-specificity evaluation. You can view the resulting published application at the USPTO (20040267148 30Dec04 Method and System for Detection of Heart Sounds) or for a more easily digested treatment see the Inovise pdf referenced below. |

| Large
Industrial Research Test System, 2004 I can't tell you what it is (not that I don't know -it's proprietary to the customer) but it has 128 RF channels and puts out about 1.3kW of power. On this project I did much of the system design and integration as well as design and layout of the multichannel output circuit boards. This was a project co-ordinated between 7 local area engineering contractors including EE (analog, digital and RF), SW and ME disciplines. |
| System features: System board size 13x14
inches.
Real time OS with Windows running as an app.High performance backplanes. FPGA interface and control circuits. 128 programmable switching supplies. 128 synchronized DDS's. Rack mounted 2kW power supply. Matched delay clocks for 16 8 channel boards. Matched delay signal routing for 128 channels. Power Pad through the board thermal management. |
