Although not expected to begin shipping inside handsets as an integrated part of a smartphone before 2016, or late 2015 at the earliest, night vision is one of the innovative uses for sensor, said Bouchard. One of the most interesting parts of the sensor market at this point in time.

Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor (M-TADS/PNVS)
The Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor (M-TADS/PNVS) system is an advanced electro-optical fire control system. Apache helicopters use the system for targeting during the day and at night, as well as in adverse weather conditions. This device has been around for some time. Since 2005, the M-TADS/PNVS has offered increased performance compared to Legacy systems. The technology has taken situational awareness to a new level by augmenting stand-off ranging for US forces, allowing those forces to get greater resolution for pilotage and targeting. The M-TADS/PNVS is designed for two-level field maintenance. It will reduce US Army operation and support costs by 50 percent over its forty-year system life. More than 1,200 systems have shipped to US Army and international customers. Production of additional systems is planned to go on through January 2015.
Thanks for the "QNH" aviation explanation. Certainly the same approach could work for SmartPhones: the GPS would provide a location and the nearest reference barometer could provide the correction factor. The one remaining issue would be the pressure differential inside the building. Many buildings run at positive pressure which would cause the "altimeter" to read a lower floor level than it should (denser air). Perhaps a simpler approach would be for the GPS to detect entry into the building perimeter, use the indoor ground level air pressure as the barometric pressure reference. It could then compute floor levels by the associated pressure reductions as the air pressure reduced with increasing altitude.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
