If you missed the live Sensor Fusion and Contextual Awareness Hangout, you can watch the playback on the ARMFlix channel on Youtube here:
You can find bios of all the participants on the intro blog here.
I asked Will Tu of ARM, who facilitated proceedings, for his 'Top 3' highlights:
1) Innovation in sensors is happening on multiple vectors
2) But some of the challenges are the same...
3) Ecosystem is key
The second point really jumped out at me as playing to what many would call the core strengths of ARM and our partners - including that balancing of power versus performance in ever more varied and demanding applications.
Enjoy the show!
Cost: size dependant, perhaps a proprietary protocol-interface would be suffice, add a 6 pin micro to each sensor/s cluster some bit bashing to design a single phantom powered (OC) wire half duplex slave interface back, (with sleep and sensor ID flashed in to the device ( etc)) to the main CPU. This would save on the cost of wiring/interconnection and connectors/space.
The master CPU broadcasts as sensor ID to all sensors connected on the bus, master wait for response etc etc.. Just a thought !!
