Five Iowa companies are among those being featured at what’s billed as the world’s largest trade show, underway this week in Las Vegas. The Consumer Electronics Show includes 27-hundred exhibits across 35 football fields of space.

Brian Eddy is C-E-O of Q-3 Innovations, based in Independence. Eddy says they’re getting great responses for their product called Alco-Hawk. Eddy says: "It’s a small digital device that allows you to quickly test your alcohol level to see whether or not you should be driving, whether or not friends or family should be driving. A lot of parents are also using them to test their kids." He says high schools are making use of the handheld devices to test students before they come to school or come to school events.

Various versions of the devices sell for between $50 and $300. He says they’re reusable and come with replaceable mouth pieces and it gives people the ability to make an educated decision about driving if they’ve had a few drinks.

Q-3 is also highlighting other electronic devices, like a solar-powered radar detector and something called the Thermo-Hawk, an infra-red thermometer. It allows you to test the temperature of an object without touching it, something that could be of use with barbecue grills, in the H-V-A-C industry and looking for hot-spots in the computer industry.
