If 3M or any other conglomerate is buying up a little niche company like this, they must believe it's a growing market. I guess they think there's potential and they might have government relations folks at their disposal, but maybe that's a question for another witness.
How many different kinds of products, then, could there be? You would think it's almost one-size-fits-all. There can't be too many variations on the theme. I would think it's either ankle bracelets or a bracelet.
I understand you could have a GPS system, you could have a biometric system, you could have a radio frequency system, but within each category there can't be too many options, can there? We're not at that level of market segmentation, I would think.
