Management at Sensit had a vision for a body-warn gas alarm; something that would alert the wearer about dangerous concentrations of harmful gases.  Almost nothing was defined, so our engineers defined it. We recommended that the alarm be simultaneous flashing, loud noise, and vibration. Further, we recommended that the device accommodate replaceable batteries and be proof against serious abuse, like immersion and impact.

Then we proposed a novel, manufacturable and cost-effective way to achieve those things.

Less than four months later, the owner threw a beautiful working prototype off the roof of the factory to evaluate how tough it was.  Intact and fully functional (if a bit scuffed) that prototype illustrated that the design was sound and that Porticos had, once again, exceeded expectations.  We’ve been pleased to see that product continue to sell as a flagship product for more than a decade.
