I did a search for "blister pack opener" on Google. I didn't have time to pursue the various leads but there appear to be general purpose blister pack openers on the market and also devices to aid in opening pills in blister packs.
I went to this link:

where I found: "Other new Ableware products designed for individuals with limited mobility or strength include a clear plastic Pill Pusher Blister Pack Opener, which requires only a small amount of palm or finger pressure to pop pills out of their packaging"
But this was what really caught my attention (on the same link): "ARR Health Technologies, Swampscott, Mass., is offering its Robi-Comb electronic lice detector and remover as a chemical-free alternative to traditional chemical treatments for head lice. Powered by one AA battery, the coated metal-toothed comb emits an audible signal when it detects lice, then kills the louse with a small electrical discharge. Insulation on the tips of the comb's teeth protects the patient's scalp, according to the company."
Well there you go. All of you who invented electronic lice detectors years ago but never patented them - it wasn't such a lousy idea after all!
