They invented the O2 sensor that lead to electronic fuel injected engines being awesome, and they still produce huge numbers of OE automotive engine management systems.
They've got their self-branded tools, but when you buy a Dremel widget or a Diablo saw blade, you're also buying Bosch.
I used to get home aquarium equipment that was made by Bosch. I've owned a (rather high-end, for the time) aftermarket car stereo that was a product of Bosch. The Bosch dishwasher I had was a skookum choocher despite being relatively inexpensive and near the bottom of their line.
They make industrial automation hardware and sell plant engineering services. They build and run factories that manufacture semiconductors.
I'm only scratching the surface here.
Chances are excellent that you've got stuff related to Bosch all around you, wherever you go.
