I didn't hear your presentation on the call but I surmised from your presentation that you're prototyping with aromatherapy to keep drivers alert - that's an interesting idea, I'd look at other ways of releasing scent besides nebulizers since they equipment is so big and I know I personally wouldn't want to drive with that on. Maybe prototype some attachments to the wheel or hacking air fresheners people already attach to their dashboards.
The Cleveland Clinic Innovation Summit had some companies working on the speed and reaction time sector that would be great resources to look to and see if they've done some of this research in the car. From what I heard, it was mainly sports training so far. Either way, they should know a lot about reaction time research.
