ENERGY ASSOCIATES
Electrical Engineering Manager
Mr. Judy is responsible for managing instrumentation and control engineering assignments on Energy Associates' projects. He is experienced in the design and construction of: power distribution systems; control systems including the application of programmable controllers, computers, and microprocessors; and lighting including roadway, area, and emergency locations. Project experience at Energy Associates includes:|
* Tri-State Generation & Transmission. Prepared electrical designs and modified the system control logic for a rotary coal breaker addition to 110 MW Nucla Station, Nucla, Colorado

RICHMOND ENGINEERING WORKS
I&C Engineering Manager
Mr. Judy manages all aspects of electrical, instrumentation, and controls engineering.

SVEDALA - MCNALLY WELLMAN
Service Engineer
Mr. Judy was the Controls Group Manager for the Service Department of Svedala-McNally Wellman Co. As the leader of the Controls Group, he was responsible for the technical content and the commercial results of electrical upgrade projects on a variety of bulk material handling machines. Typical projects include replacing motor-generator sets on old clamshell unloaders with new microprocessor based digital SCR drives. Replacing old relay control systems with Programmable Logic Controllers to automate stacker/reclaimers and rail car dumper/positioners. He also successfully developed McNally's first application of flux-vector digital AC frequency drives to rotary car dumpers. In 1992, Mr. Judy was awarded US Patent No. 5,174,212 for the Positioner Optimizing Controller (POC). The POC is a system of hardware and software that allows the deceleration point of the positioner to adjust as the weight of the train varies. The net effect of the system is to allow the positioner to handle trains of varying configurations with the shortest possible cycle times.
During this period, he also had administrative responsibilities for the group including annual reviews, recruitment of new employees, and scheduling of work assignments. He also led the sales effort for many large mechanical and electrical upgrade projects.

DRAVO-WELLMAN COMPANY
Service Engineer
As a Service Engineer, Mr. Judy developed many of the techniques used in the company's electrical upgrading projects. He structured and developed PLC programs. He initiated company adoption of the Sate-Diagram method of designing software. This method allows the engineer to use Boolean algebra to prove the sequencing logic before field installation. Incremental and absolute gray code encoders were applied to the machines and interfaced with the microprocessors to precisely track the position of the machines. Mr. Judy developed and successfully applied expert system diagnostics. He designed and implemented the redundant "Emergency Stop System". Mr. Judy also assisted customers with emergency breakdowns, often leaving on a moment's notice to travel to a customer's site to troubleshoot electrical problems.
