5 Projects 2005 to September 2007, May 2008 to December 2008, May 2009 – August 2010, June 2011A. Updated C# code written using Visual Studio 2000 and the Excel2000 libraries to run with the current Visual Studio IDE.

I developed Coldfire microcontroller application code in C/C++ to generate test patterns for the Ultra Violet Direct Imager (UVDI) Module. These test patterns required two levels of bus translation (32 to 20 bit and 20 to 40 b it) in order to convert Coldfire bus to the test board FPGA bus and then to convert the test board FPGA bus to the UVDI bus. Typical test patterns created included block based “walking 1’s” - foreground/background; 4 amplitude level “walking 1’s. More than 20 different test patterns were generated. The original tasks of this project required delivery within 1 month from the beginning of code generation. This goal was met.C. While SLM was part of Cypress, I performed USB2 characterizations on the Cypress “Ovation” mouse chipset. These characterizations included power, timing, signal, and protocol testing.D. I implemented an Applications Programming Interface (API) for a manufacturer’s test instrument, which was written in and for C++, for an automated test program written in C#. Converting API’s written for C/C++ to work with C# programs is an advanced task.

A. I troubleshot unacceptable audio noise during the commissioning of a “Call Center” to assist deaf users in making and receiving telephone calls.

The instrumentation is able to withstand normal surgical sterilization methods and meets FDA standards.

A. I was brought in to complete a stalled development project that required, by contract, delivery of high volume production units within 3 months of my involvement. At the time, no working prototype existed. Contractual obligations were met, allowing One Touch to triple its yearly sales. B. I provided electronic and mechanical designs for second and third generation products. Electronic design included the telephone interface (FCC Part 68), RS485 serial communications port, analog pre-processing for digital audio, digital audio, 80C51 microcontroller, and interface to ISA bus.
