Temperature controls can factor into litigation in a variety of cases including the loss of perishable goods, lost product in manufacturing or processing facilities, fire damage, or personal injury matters involving scalds and burns. In this article, Electrical Engineer, Kenneth J. Kutchek, P.E. and Mechanical Engineer, René Basulto, P.E. provide an introduction to temperature control as it relates to expert witness investigations.

Their discussion includes an overview of temperature control systems, the major components, and potential failures.

The failure of a product or system to turn on/off or respond to input can lead to a broad range of injuries or property damage. Whether it be a seemingly innocuous device like a coffeepot, or a heavy duty industrial cooling system, the root cause of a failure can often be traced to electrical controls.

So what are electrical controls, and how do they potentially factor into your casework?

This webinar simplifies the topic of electrical controls, starting with the basics and building up to examples of actual incidents caused by control failures. Experts from our electrical engineering group provide insight on evaluating these cases and guidance on discovery questions to ensure that adequate information is available for proper forensic analysis.

“Electrical control” is a specialized discipline of electrical engineering where, to put it simply, electrical circuits and programmable electronics are engineered to turn machines and consumer products on and off. That is an over simplification but after all the engineering design, functional requirements, safety requirements, testing, and many other required activities are completed, the product or machine will turn on and off in accordance with desired parameters.

In this article, Electrical Engineer Jeffrey Kobilka explains what some of those devices are, how they can fail, and how an electrical controls engineer could be beneficial to your case.

The combination of water and electricity can create dangerous and unintended paths of electrical current. Depending on the amount of current, the duration of exposure, and the current path through the body, electrical exposures can result in a broad range of injuries, from minor tingling to severe burns or death.

This article discusses some of the electrical safety requirements relevant to pools, spas, and fountains.

In this article, Electrical Engineer, Kenneth J. Kutchek, P.E. provides an introduction to electronic machine safety guards.
