I wrote an application level USB DLL using overlapped threaded reads so the limited buffers on the USB device never overflow. I also used boost queues, threads, and signal2 to provide events when USB devices were connected, and when buffers are available. I then wrote an interface/facade class to process this data using the Intel Performance Primitives. This whole process takes less than 2% of the CPU of an Intel Atom D525 SOC system. The software I have written has been re-purposed for Bluetooth LE virtual comports. Wrote Python scripts to test DLLs for USB 2D doppler capture.

I implemented the capture application myself, while the client viewer application was farmed out to a 3rd partydue to time constraintsUsed C++, Win32 API,Open GL, MFC, COM, and DirectX to create an application that was hardware independent. Chose the open source database engine, and open source graphics and imaging libraries to develop an entirely new opthalmic image capture software. Implemented Conjugate Garient Method to Demosaic CCD for illunis 11 megapixel camera. I parallelized the Demosaic process so that on a dual Xeon the Demosaic took less than 1 second. Originally this application was written with Linux (wxWindows) in mind, but later it was determined that the tech support staff was more comfortable with Windows, so I moved all my code to the Windows Platform.This application captured from 6 different camera systems using CamLink, GigE, frame grabber and proprietary interfaces. With the help of contract consultants specified and developed a completely new image review software, all graphics rendering used OpenGL. Utilizing XML embedded into the PNG images the review software is able to track each and every image and any and all manipulations performed on the images. Further developed automated archival and cleanup software that run as services. This suite of software was then tied to a web based analysis software package called Ocunet.Ophthalmic Imaging Systems 04/1997 to 04/2002Principal Software EngineerConverted their entire 16 Bit Windows 3.x program consisting of 185 modules to Windows NT. This application used Windows C++ with MFC, Win32API and COM to provide database independence. This was accomplished in approximately 4 months. This application used no less than 5 separate threads with pipes for communication. Added DICOM compliant file saving and SCU and SCP functionality using the DAVIS DICOM communications toolkit. The NT product was the current deliverable for all new systems. The product acquires images from a CCD color or grayscale camera using several different frame grabber boards at a rate of 1 frame/second. Instituted a program structure that allows the use of other imagegrabber boards and camera combinations with no change in the main application. This has been shipping so that we can utilize 12 bit gray scale systems for our high end customers, while the low end cameras are also supported by the same application. I added DICOM capability using the Leadtools toolkit, and DCMTK and DICOM Structured Query/Response capability to satisfy the Veterans Administration requirements for interoperability. The images are used by ophthalmologists to diagnose retinal and corneal problems.I created several COM classes to provide 3rd parties access to our database.EiGEN Medical 04/1994 to 04/1997Senior Software EngineerThe 3 member software engineering team used Visual C++ with the MFC classes and Borland C++ 5.1 to develop X-Ray archival software in the NT operating system. The software is highly user oriented, extremely usable to the degree that no manuals are ever consulted with this product. The last project required making an NT PC acts as a SCSI target device so that a proprietary hardware device could transmit information to the NT box which then acts as the server for a medical intranet. Helped developed an intranet utilizing HTML and CGI code. While no JAVA code was used in this product I have written several classes for my own amusement and have used our intranet to be sure that they work as intended. That way the current proprietary hardware can be utilized in an open system.Wrote several RS232 interface modules to allow the EiGEN specializedcontrol panel to be used in place of a mouse and allow the special "menu" and"keep" keys on their interface box to act the way to access the menu andnavigate within the menu. Thoroughly familiar with the use of sockets andthe MFC classes that allow streaming over the NT and Windows 95/98 networking. Wrote software that converts EiGEN proprietary optical disk format into a corresponding CD-ROM format so EiGEN images would conform to the DICOM 3.0 standard.

This software was developed using Borland C++and the Object Window Libraries. While the heart of the software is the DLL toreceive data from the Photon interface card my pride in the project is theimpressive multivariate interface which allowed the user to view this information in a myriad of ways simultaneously and to save the current settings as a specialized file so other users would not be disturbed when the options and window placement were changed. This software development effort yielded 3 products that are superior in speed and flexibility to the previous offerings of the company. The software is device independent through the use of DLL's to provide all the machine interface and provides for such sophisticated graphicsas 3D constructions, 2D contours and mathematical fitting of nonlinear functionsat such rapid rates that the user may have all views going simultaneously andstill maintain a refresh rate that was as fast as the sensor could provide.Luxtron Corp. / XINIX 06/1989 to 06/1992Software ManagerThe Endpoint Controllers and Particle Sensors developed by LUXTRON/XINIX are themost sensitive and sophisticated controllers in use for the manufacture ofIntegrated Circuits.
