Really? Which bits of the technology were infeasible prior to this?
- jessaustin 9y ago2004 was a long time ago. Can we just assume for the sake of discussion that the state of the art in electronic devices was different then?
- joosters 9y agoWe're talking about a small piece of circuitry that detects a current. This was possible in 2004, it was hardly the dark age of electronics back then. Besides, the more complex part of the sawstop, at least to my eyes, is the part where you have to stop a big metal blade from spinning very fast ASAP. Just putting some brake pads on it like a bicycle wheel is not going to be good enough.
- balfirevic 9y agoPoster above said that the stopping works differently in Bosch saw.
- jononor 9y agoAny electric motor can be ran as a generator, which can be used to do electronic braking. It is the foundation for regenerative braking on electric cars and often used on big trailer trucks as the primary braking system.
- logfromblammo 9y agoThe theremin, a device for detecting fingers using capacitative coupling, was patented in 1928. It output an analog audio signal, where pitch indicated proximity of one hand, and volume indicated proximity of the other. The children's game Operation used an effective means to detect when the game's forceps contact the metal chassis. Can we assume that the difficult and novel part of the invention is not generating the sensor signal, but acting upon it quickly enough?
