The project http://qcn.stanford.edu/index.php uses computer hard drive
MEMs
accelerometers to aid in tremor analysis, aiming at developing earthquake
prediction science. Potentially they could also use PS3 game controllers.
A higher quality data source could be supplied by providing wireless
equipment
vendors with incentives to include MEMs devices in enterprise access points.
These devices are generally placed in clusters and do not get moved around
as
much as a laptop, so they would provide a more stable base.
Moreover, if an accelerometer is combined with a magnetometer, vendors
could
improve their product by allowing radio resource management systems to
automatically detect the orientation of access points. This would be a side-
benefit, reducing manpower costs involved in enterprise WiFi network
provisioning. Currently, antenna azimuth and elevation and AP location are
entered into mapping utilities manually -- or more to the point they are not
entered because it is too much work.
AP location and antenna orientation information will become more critical as
RFID location systems become more essential to business operations and
active frequency management is needed to combat spectrum saturation.
So the industry has motive to do this, but it probably would not be cost-
justifiable as a feature. With public or nonprofit incentive, both parties could
benefit.
Random business rag.

In addition to the QCN, several earthquake monitoring sensor networks
are already built and maintained at public expense. This would just be
a combination of the QCN approach and the direct implementation
approach. |
|
| |
In essence the idea is to still "take advantage" of the provisioning done
by the enterprise -- power, stable location, network access, etc, but be
able to choose a quality accelerometer. |
|
| |
QCN requires staff and developers. It isn't free. Likely it is payed
for by taxpayer dollars and/or private educational grants. |
|
| |
This idea might offset the need for more expensive dedicated
monitoring networks, as the costs are: legal costs, software
development, a small amount of extra engineering, and maybe about
a buck a unit to add the actual chip, what cost will decrease over
time. It has the potential to reduce the cost to the public coffers. |

If you are going to routinely vote down every idea that uses public
financing, maybe you'd be happier on another website. Like Free
Republic. |

Any idea which concerns the public good could be considered a "let's all." That doesn't make such ideas bad ones. The main issue of whether a "let's all" idea is appropriate for HB is whether or not the people whose participation the poster desires, would have an appropriate incentive. |
|
| |
If the idea were stated to more clearly emphasize that computer hardware manufacturers would be paid by an external organization to add electronics to detect earthquakes, magnetic north, etc., to enterprise systems, I'd give it a bun. |

Perhaps a software upload to the Wii network to
utilize the accelerometers in the wiimotes? |
