Safety must be an engineer’s primary concern, both for the sake of expensive equipment and the priceless lives of those who use it.  Please read some of blogs we have written on the topic of safety.

Part 2: Self-driving Cars Expand the Fight Over Airwaves

2018-11-26T09:53:05+00:00

Engineers Say Public is Hungry for More Wi-Fi Capacity, the telecom industry is looking to snatch control of underutilized airwaves reserved for the auto industry. But this is coming just as carmakers begin to make progress on developing and adopting technologies for connected and autonomous cars that currently rely on that spectrum. The Big Picture: Tech and telecom companies have been fighting for years over spectrum to support exploding demand for mobile services and smartphones. Automakers have had exclusive access to a band of spectrum for almost 20 years but haven't done much with it, prompting telecom providers to argue, "Use it or lose it." The Dilemma: Some safety advocates and automakers worry that commercial Wi-Fi will interfere [...]

Mechanical Engineers Support the Film Industry

2018-02-09T23:06:34+00:00

The entertainment industry relies on "entertainment engineers," e.g. mechanical engineers, electrical engineers, and others for standards https://www.smpte.org. Perhaps more importantly,  the movie industry requires Licensed Mechanical Engineers to safely innovate and amaze.  Film sets are complex physical productions, most of which are not digital special effects.  The film industry utilizes Licensed Mechanical Engineers to create complex props and various special effects that move, exploded, burn, and fly.  The mechanical engineers specializes in designing and making a wide range of mechanical devices that fulfill a specific purpose for the film or set they are engaged, or modify available technology to quickly achieve stupendous results.  Licensed Mechanical Engineers also help in structural aspects of heaving rigging, such as lighting (See above Fig. 1 [...]

Licensed Mechanical Engineers Help You Ditch Suburbia

2018-02-13T23:41:15+00:00

Licensed Mechanical Engineers Help You Ditch Suburbia Licensed Mechanical Engineers Ensure Vehicle Safety and Comfort The recreational vehicle industry (Fig. 1) is flourishing.  People can use their RVs full time part, part time or travel the country for months at a time. A Licensed Mechanical Engineer (Licensed Mechanical Engineers Role in Manufacturing) makes certain that travel is safe and comfortable at the same time, without missing out on the comforts of home and your favorite kitchen. (Fig. 2)  Recreational vehicles' kitchens are designed with adequate ventilation to ensure that no fires occur.    Across that spectrum, the RV industry is enjoying an unprecedented growth.  Who are these RVers? They love the beauty and solace of being outdoors, abiding [...]

Wind Load CFD Modeling for Rooftop Elements Compared to ASCE 7

2018-02-20T11:28:46+00:00

  Wind Load Comparison between CFD and ASCE 7 for Rooftop shapes Welcome back to our blog series on the phenomenon called Wind Load CFD Modeling and how it affects civil and mechanical engineers.  Wind Load is the force that blowing wind exerts on any device or structure that extends above ground level.  After an initial introduction to the factors that affect wind load on an object, I compared three different sets of wind load calculation methods using three simple objects, hypothetically placed on a 100-foot-tall building.  Starting with generic drag equation for the first equation, added two modification coefficients called "gust factor" and "exposure coefficient" for the second equation.    I used the model for rooftop objects for the [...]

Semiconductor Safety: Pyrophoric Gases

2018-02-21T15:25:24+00:00

Fig. 1 Tall Fire from Chemical We have written about pyrophoric materials in a number of Glew Engineering’s previous blogs on safety in semiconductor fabrication, but have yet to cover how to define it or its danger.  At its simplest, a pyrophoric substance is any substance that spontaneously ignites in room temperature air.  As one might imagine, spontaneous combustion on contact with the regular atmosphere we live in can be quite dangerous. Last year, Glew Engineering assisted a research lab in designing a safe gas distribution system for their plasma-enhanced chemical vapor deposition chamber.  During the initial work, the building administrators and safety managers were concerned about the lab’s proposed use of silane and germane, two pyrophoric and toxic materials.  To them, [...]
