Objective
|
 |
|
 |
| |
I offer interdisciplinary skills in physics, machining, automation, engineering and R & D gained from working in telecommunications, aerospace, automation, medical devices, ordinary production machining, and other areas. I have shown an ability to conceive and apply creative solutions to many problems. This is partly due to my capacity to address both the theoretical/abstract sides of a problem, and the practical/hands-on aspects simultaneously. I can understand both the mechanical engineering and electrical engineering sides of an issue, with the additional ability of knowing many manufacturing processes. This is evidenced by my work history.

Mark Henderson CEO
Micrin Technologies, LLC, MicrinPrecision Fabrication LLC, Top Gun Products LLC, MegaRail Transportation Systems Inc.
These companies are all related. After designing and installing a material handling system at Top Gun, I worked with the controll systems for MegaRail and became the Primary Contact for an IP case that Micrin Tech was fighting. After nine months I was made Chief Operations Officer for the holding company and General Manager of Micrin Precision Fabrication.

Accomplishments at MicroFab include:
- Developed the first jet based olfactometer. This has since been used to develop a clinical diagnostic tool for Alzheimer’s and Parkinson’s. It has also been the basis for pheromone dispensers for advanced pest control, for kiosk odor displays and also for a computer peripheral. It has led to the development of a research olfactometer which can vary odors in real-time in an arbitrary way and do so for the right and left nostril independantly. Many inovations were required, including low cost jets, low cost jet drive electronics, programming if PIC controllers as well as GUIs. Current work has evolved into a calibration vapor generator. NIST ordered the first one, and other models are being developed.
- There was a need for micromachining, but the available micro CNC machines were not what we needed, so I built a system from the ground up. It includes not only automated movement, but also automated control of three coolants, a jet drive, spindle on/off, and a G code interpreter.
- Developed a dye assisted laser ablation method to obtain painless sampling of intersticial fluid. The end use of this is for diabetics to monitor their glucose levels without the needle stick they now use.
- Developed a jet which will dispence fluids with roughly ten times the previous viscosity limit. One of the key areas of application for this would be adhesive dispensing.
- Rewrote code for a Delta Tau controller that doubled ‘print on the fly’ speed and made data downloading from the host a continuous background task, enabling arbitrarily large arrays and eliminating data downloading delays during printing.
- I am inventor or co-inventor on several patents, including a diagnostic tattoo.

Decibel Products - Allen Telecom Group

Dallas, TX 75247

Andy Cartin VP Enginering (now at dbSpectra)
Senior Manufacturing Engineer - Responsibilities included; automation of manufacturing processes, Design for Manufacture/ Design for Automation (DFM/DFA) of antennas and filter products, develop new manufacturing processes, tooling design, fabrication and implementation, Continuous Flow Manufacturing (CFM) implementation, and training of technical personnel in the above disciplines.
Accomplishments at Decibel Products include:
- Designed and installed the PCS antenna production line. The needs of this line are to produce antennas at high volume and high mix, following the principles of CFM. The line had to be installed before the product was designed in order to meet schedule. It was still running well at least a year after I left.
- Designed and implemented the first computer controlled automation at Decibel Products. This unit is able to receive scheduling information from the main network to drive production. It marks component location and dispenses glue for over 150 different models of antennae. Programming was done in Visual Basic, creating a user interface that has required minimal training (less than 10 minutes during the first six months).
- Screwless component attachment was successfully prototyped and tested.
- Glueless/screwless radome attachment was conceived and successfully produced.

University Of TX Arlington Hypersonics Reseach Ctr
701 S Nedderman Dr
Arlington, TX 76019

Donald Wilson Acting Chair
Research Associate - Pulsed Detonation Engine - Designed/invented and built two styles of ignition systems at the hypersonics research facility. The first was for single pulse work and the second system was able to produce an arc of up to 5 joules/pulse at 200 Hz (as compared to millijoules for current racing ignitions). The arc produced peaked at about 3000 amps and had 90% of its power delivered in less than 10 microseconds. This power delivery profile was chosen so as to have the arc produce a shock wave. This was done under a NASA contract and in conjunction with Lockheed and Rocketdyne. NASA used the finished unit further at another facility.

Frank Lewis Endowed Chair
Prototype Development Specialist - Responsibilities included; manage model shop and waterjet facility, develop proof of concept models, safety certification of machine shop equipment, waterjet and its robotics, training of staff and students in design and fabrication.
Accomplishments at the Institute include:
- Mechanical design and fabrication of a Stewart Platform robot. This is a six axis, parallel link structure. It made the cover of the annual report for three years in a row.
- Fabrication of solderjet jet head and misc. related hardware. This project was aimed at producing a process similar to inkjet as a way to “print” with solder.
- Design and fabrication of a high pressure coupling for 60,000 psi water which produces no decoupling force. Now being used by Pratt & Whitney in an automated work cell. This contract was completed under budget and ahead of schedule. I built the initial working proof of concept model in under 4 hours with a cash outlay of less than $20.
- Design and fabrication of a staple removing end effector as part of a proof of concept for fully automating tax returns. I produced the hardware and associates produced the software for this to facilitate a major companies bid to the IRS.
- Succeeded in drilling diamond with garnet. It is no longer true that the only way to cut a diamond is with another diamond.
- Wrote modular text cutting program for abrasive waterjet robot controller (Allen-Bradley).
- While I was responsible for safety in the machine shop there were no injuries (students were allowed use of all equipment).
- I was co-author on several papers pertaining to the design and control of Stewart Platform robots.
