Employment History:

Nov. 1984 to Mar. 2000: Sr. Electrical Engineer for Laitram Corporation. Team leader of group responsible for selection, design, and programming of computer vision, robotic, and industrial control systems for use in a food processing application.

Jan. 1991 to present: Self employed (part time) under business name Spectra One. Free lance production of full digital audio recordings for demos, auditions etc.

Numerous part time jobs during college and high school, most technical/engineering related.

Embedded Device Control Experience (Axonn LLC.):

• Responsible for processor selection and all embedded software for the "Axess Transmitter" product line. This is a wireless, spread-spectrum, battery operated industrial monitoring and control device. The embedded processor used is a TI MSP430 series microcontroller. Key design criteria were extremely flexible configuration for industrial control and monitoring and extremely low current usage for multi-year battery life. The product description can be found at: http://www.axonn.com/product/end.html.
• Developed all software and selected the microprocessor for an RTU interface to Axonn's 2 watt narrow band cellular data collection transmitter. This is also a battery-operated device featuring multi-year battery life and uses the TI MSP 430 series microcontroller.
• Developed the tasking and control software for a 100 milliwatt 868 megahertz telemetry transceiver for the European market. This software featured a critically timed interface to an Atmel DSP to encode and decode an Axonn proprietary 16 symbol narrow-band digital modulation format. The microcontroller was a Temic/Atmel 87c54.
• Re-designed a legacy spread-spectrum receiver circuit, used in a building environment control application to use a new microcontroller when the legacy controller used in the circuit became unobtainable. Extensive and critical microcode re-timing was required to achieve the correct spread-spectrum chipping sequence. The microcontroller used was a Cygnal C8051F series.
• Designed, at the board level a PC-104 based, Linux based, controller for a Cellular Transceiver system. This is a 10-channel system utilizing an Axonn proprietary 16-symbol modulation scheme. Wrote all of the software applications and custom drivers specific to controlling the cellular transceiver running on that controller. Key design criteria were extensive self-diagnostics and the ability to recover from hardware failures. Designed a custom embedded Linux installation and run-time environment for the controller. A custom SNMP MIB was provided for remote monitoring. Virtually all software and firmware in the system, including the Linux kernel and run time environment itself, was designed to be remotely upgradable. A brief overview of the Cellular system in which this controller was used can be found at: http://www.ustelemetry.com/ustc/techintro/techintro.html Virtually all of these cellular transceivers have now been running for more than two years without a single glitch, failure, or reboot of any kind.
• Developed custom software for an "MCTS" (Master Cellular Transceiver System) Linux based server. This software served as the master controller for a cluster of Cellular Transceivers.

Hardware/Firmware/Device Driver Programming Experience (Laitram Corp.):

• Sole Author and Maintainer of The SST-5136 Driver and software suite for Linux. This is the Linux driver and support Package for the SST CAN-Bus/DeviceNet interface cards. Driver supports ISA, PC-104 and PCMCIA versions. http://www.spectra-one.com/dn5136man.html
• Contributing author and maintainer of the Matrox Meteor Video Capture card driver and ancillary applications for Linux. http://www.spectra-one.com/meteorman.html
• Developed a function library for controlling Omron PLC's from a central UNIX host computer. Developed on ISC UNIX, ported to SCO UNIX and Linux. I have written Serial and TCP/IP variations of this package.
• Developed device drivers and function libraries for controlling multi-axis servo and stepper controllers from a UNIX host. Developed on ISC UNIX, ported to SCO UNIX and Linux.
• Have developed several other UNIX device drivers for real time data capture and video grabber boards.

Artificial Intelligence/Industrial Automation Programming experience (Laitram Corp.):

• Written extensive artificial intelligence programs for interpreting noisy and incomplete video images and defining a three dimensional water-jet cutting path from the information using sophisticated heuristics to make decisions based on incomplete or conflicting data.
• Developed supervisory system for industrial automation system. Linux computer monitors operating parameters of manufacturing line and automatically recovers from mechanical failures.
• Developed a user interface for the industrial supervisory system. Interface features text and graphical modes of operation and several levels of user privileges.

UNIX/Linux Programming and Administration (Laitram Corp.):

• Contributing author to the "Bigphysarea patch" to the Linux kernel. This patch helped make possible the "Video for Linux" project and other innovations in Linux development.
• Maintained network of UNIX/Linux computers on local LAN and with Internet connection.
• Wrote and maintained department web pages. Some with CGI interface to databases. Fluent in HTML syntax.
• Installed from scratch dozens of ISC UNIX, SCO UNIX, and Linux systems.
• Troubleshot and repaired damaged UNIX filesystems.
• Built most of the project's Intel based hardware from scratch.
• Maintained the following Internet services on UNIX and Linux computers: ftp, telnet, http, DNS, timed, smtp, POP 3.
• Experience using/programming/administering the following flavors of UNIX: AT&T Sys. V r. 3.2, AT&T Sys V r. 4.X, ISC UNIX, SCO UNIX, SCO Open Server, SGI IRIX, Linux kernels 1.0.x - 2.3.x.

Electrical Engineering Experience (Laitram Corp.):

• Designed electrical interface circuitry to interface 16 strobes to a UNIX computer and fire them in synchronization with the scanning of a TV camera, each strobe illuminating exactly one video frame to achieve a set of images with precisely structured lighting. I also wrote the UNIX driver software that interfaced with the circuit and the strobes.
• Extensive automated motor control experience.
• Designed wiring harnesses and power and control signal distribution for entire manufacturing lines in washdown environments.
• Designed extensive DeviceNet Networks. Interfaced machines controlled by UNIX or Linux computers and machines controlled by Omron PLCs on a common network and developed user interfaces for those machines.
• Experienced in PLC programming, device interfaces, and ladder logic.
• Experienced in specifying and integrating stepper and servo motors in robotic applications.
• Experienced in design of robotic devices for up to six axis coordinated (synchronized) motion.
• Listed as inventor or co-inventor on 5 patents.
