General Overview

John has more than 22 years of broad practical experience in Electrical Engineering. He is presently a principal Engineer with responsibility for system evaluation, analysis and design. He has expertise in system engineering including needs assessment, requirements definition, alternative analysis, functional decomposition, system design description, quantitative and risk-based decision analysis, system specification, testing, and construction observation. John has applied this expertise to the design of Supervisory Control and Data Acquisition (SCADA) systems, telemetry and telecommunications systems, and security systems.

Technical Overview

John is a Principal Engineer involved in all projects at Timberline. Throughout John’s career, his experience has been related to specialties that are directly applicable to SCADA, communications, and security system design. John’s communications system experience has spanned the evolution of equipment from being predominantly analog technology to almost exclusively digital technology. During this transition, he was involved with changing requirements for propagation analysis, site selection, equipment specification, and test and acceptance procedures. During his time with Mountain Bell he had the opportunity to work closely with Bell Laboratories and developed detailed documentation for operation of their remote data acquisition system (PQUARK), which was used for digital transmission testing at remote microwave repeater sites. In addition, John developed an algorithm for obstruction fading predictions and directed the development of a baseband equalizer for use within GTE SPRINT.

Building on his communications experience acquired at Mountain Bell and GTE SPRINT, John directed an engineering team it the development, verification, and implementation, of semiconductor characterization programs for Sandia National Laboratories. This effort required strict adherence to military standard test procedures and the development of specialized test configurations for components that were to state-of–the-art for standard procedures to exist. These specialized configurations required software and hardware development to automate the measurement and data acquisition process. These test systems were optimized and verified by applying statistical process control techniques to the acquired data and the results used to support the configuration management program applied to these tests.

John’s career experiences have been uniquely applied to SCADA and communications system evaluation, analysis, and design. His telecommunication background provides Timberline Engineering with strength in an area that is typically weak for most SCADA consulting engineers.

Other Experience

The following are examples of projects John was involved in and experience gained throughout his career before working for Timberline.

• Contra Costa Water District, Concord, CA radio replacement project including interference analyses to ensure reliable communications, with primary focus on propagation analysis, path design, and system engineering and insuring that the new digital equipment interfaces properly with the existing SCADA system and that cutover has minimal impact on water system operations.
• Nextel Communications cellular radio project in Elk Grove, CA involving RF intermodulation analyses and coordination of multiple cellular and MAS users at a common tower site.
• Dam Filling Notification System designed for the Albuquerque Metropolitan Arroyo Flood Control Authority in Albuquerque, NM.
• Northern Colorado Water Conservancy District spread spectrum MAS radio and SCADA system, a turnkey design-construct project which supported a 30-mile pipeline serving users along the Front Range between Loveland and Denver, CO, including the Carter Lake gates and flow control stations along the pipeline.
