Authored multiple patents, 33+ granted to date, several others pending. Performed freedom to operate analysis, invalidity searches, worked with counsel to develop claim charts, and assessed IP disclosures from Luminex staff for patentability.Analyzed technologies and IP from academia and industry. Presented findings to executives considering partnerships, corporate acquisitions, or legal recourse.Worked with end users and marketing staff to solicit and translate customer requirements into specifications suitable for design input. Worked with external vendors to define and supply critical custom electro-optical components. Employed outside design firms for supplemental jobs.Developed algorithms for digital signal processing, thermal compensation of optical / analog circuits, and rapid convergence calibration methods. Conceived and implemented an optical multi-decade dynamic range extension method with a handful of low-cost components. Wrote applications in C++ and C# to control instrumentation, analyze data, and perform system modeling.Conceived and prototyped a CCD-based imaging particle detector using LED illumination that became Luminex’ best-selling instrument. Developed a suite of image processing algorithms to classify and quantify fluorescent particle signatures.

Led a team of hardware and software engineers in the design of embedded PC based medical image capture devices.Transferred company design operations from New York to Texas in corporate move. Hired a new design team in Texas and managed phase out of remaining New York operations.Performed high level system analysis and designed a PCI based video frame-grabber with custom PLL generated pixel clock frequencies to 150 MHz. US patent 5,805,236 on this work granted in 1998. Wrote Visual C++ code using an object oriented methodology (Booch) to test, set up, and control the resultant video frame-grabber hardware.Led the design team in creation of NT device drivers and embedded 80C520 firmware. Brought in consultants to quickly bring self and staff up to speed on the new PCI bus and Windows NT device drivers.Managed project schedules, performed personnel performance appraisals.

Rochester, New York

Designed video capture devices to record medical images from diagnostic ultrasound machines and transmit them to network based film printers. Designed an ISA bus based video frame-grabber for capture and display of color medical images. Received US patent 5,805,236 on design work. Directed PCB layout for minimal noise on a mixed analog and digital PCB. Pixel clock generation via a programmable PLL allowed synchronous A/D sampling over multiple frequencies. Wrote control software using C++ and 8086 assembler.Taught video theory to field service personnel and directed Beta field installations. Directed technicians and software personnel.Wrote an object oriented software application in C++ for an automated video test fixture which greatly reduced manufacturing test and repair costs.
