I am an engineering supervisor at
Rockwell Automation /Allen Bradley. I have been employed there for 8 years now. I work in the standard industrial Drives group designing AC inverter drives. An electric drive is an interesting device. It is a device that controls the voltage and current into a motor. Control of these parameters allow the drive to control speed torque and position of the motor shaft. Electric drives are used in industry and commercial buildings for everything form the conveyer belts in assembly lines to the speed of the fan motor in an air conditioner.What I do there
I have been mainly responsible for the communication between the drive and the wide variety of industrial computers that can control the drives. I also supervise a group of engineers and technicians that support the drives out in the field. I have been fortunate enough to be in one the best group of engineers in the world. I have received one patent and a few other engineering awards.
Technical Interests:
I have been a real time programmer for almost my entire stint as an engineer. Real time is more interesting to me than windows or system programming. It solves some cool problems and you get to set controls in the actual hardware without some damm OS buffering commands for you. I enjoy working with the chips and the emulators. Smaller 8 bit parts to me are more fun than huge number chrunchres or DSP's (although DSP's are neat too). Smaller cheaper tighter solutions are much more satisfying than big over done systems.
Real time embedded programming involves the best in mathematics, engineering (SW and HW) and applied physics. Because it has this funny mix of disciplines, good ones are hard to find. You end up with either great software skills and the inability to change a light bulb or a hardware guy that doesn't have the slightest idea what a pointer of structure (or structured programming) is.
One area of real time that is hard to get a grip on is scheduling (not interrupt scheduling in the chip but project scheduling). The interaction of the hardware design and the interaction of the software can lead to delays that are hard to account for. I am working on methodologies that help forecast these situations.
To support some of my hobbies I do a little consulting on small projects that are not involved in what I do at work. These projects are mostly real time programming not related to electric drives, PLC programming, web page design and computer graphics work. As I am doing more and more supervision and less and less of the daily engineering work, consulting keeps my skills from getting dull. I pick these projects carefully so as not to interfere (evenings and weekends only) with work. My rates are very reasonable please contact me (
