Objective
Since June, 1994

I am a consultant specializing in embedded system design and implementation, PC systems analysis, real-time data acquisition and control, embedded GPS (Global Positioning System satellite receivers), data communications (modems, both asynchronous and synchronous, RS-232, RS-422, and RS-485, fiber optics, network TCP/IP and UDP, Internet/www, and wireless communications), RFID on compact devices (Pocket PC or embedded Windows CE), PC user interface design and implementation on Windows desktop,  Pocket PC or WinCE systems, the .NET Microframework,  scientific, laboratory, industrial machine control RFID and GIS using Microsoft MapPoint ™ and Virtual Earth ™ applications (look at this Automatic Meter Reading GIS example).   If you are interested in adding Virtual Earth (Bing Maps) functionality to your .NET or VB6 applications, contact me.

Recently, I have been developing Arduino based platforms for data acquisition and control.  Arduino is an inexpensive board that is ideal form one-off or limited production systems that have modest design requirements.  Contact me for more information.

I've completed a project for communication with Philips™ Healthcare IntelliVue™ Patient Monitor.  Connection to these monitors using a PC is an option that provides both Ethernet and RS232 serial communication.  Patient and monitor status may be transferred to an external computer for display and processing.  A subset of these data are:

  •  ECG waveforms

  • Temperature (core and rectal, as appropriate)

  • Pulse rate

  • pO2 and CO2 concentrations

  • respiratory rate

  • blood pressure (systolic and diastolic)

  • Alerts, both patient and technical (monitor)

  • and a variety of other data

The Philips Data Export protocol that conveys this data is complex, not well documented, and is not supported to any great extent by Philips.  The Data Export Protocol is described in a 300+ page document that is convoluted, misleading, and incomplete.  I spent about 600 hours working out the details required to implement this protocol in a Visual Studio .NET control. My original time estimate for this project was 40-80 hours.  You might imagine how frustrating this project became over time!  Regardless, I completed it, though far behind schedule.

I intend to write a Kindle eBook that describes the process.  You may contact me for more details, including project consultation, should this interest you.

A client list is available.

Publications
Visual Basic Programmer's Guide to Serial Communications  A Tutorial: Porting VB6/MSComm32 applications to Visual Basic .NET ASIN: B009AE7NZW  Published September 2012 by Grier, R.

Visual Studio .NET and its supported languages, such as VB and C# provide a modern and well supported application development environment. There are a wealth of legacy VB6 programs that can benefit from moving to VB .NET.

This tutorial is devoted to those VB6 applications that rely on serial communication to exchange data with other computers or devices. Porting VB6 based serial communication programs to VB .NET can be tricky. The tutorial guides the porting process and provides critical information and working example code to illustrate the process.

The tutorial also provides help for maintaining legacy VB6 applications by employing COM Interop controls and forms developed using VB .NET to add important capability that is best done using .NET tools.

 

Visual Basic Programmer's Guide to Serial Communications, Fourth Edition, ISBN 1-890422-28-2 (391 pages, includes CD-ROM). July 2004, Text revised July 2006. Grier, R. For more information, to read reviews, or to order this book from Amazon.com or directly from me, click the book image. 

I add new example source code and utility programs to the included CD-ROM to keep the book up-to-date with the latest changes in VB .NET.  This includes many new articles that are intended to provide detailed insight into the example code.
