Autonomous mobile robots rely on sensors to navigate through their environment.

If you've ever worked while resting a laptop computer on your lap, you know that computers emit heat, and the more powerful the computer, the greater the heat produced. This is a problem because electronics really don't enjoy elevated temperatures. A hot computer is a slow computer or, worse, a computer that will cease functioning.

In an increasingly wired world, knitting together data from disparate sources into an interoperable whole can present disaster managers and first responders with critical information during a major emergency or crisis. Building on a vendor-neutral interoperability framework for Web-based discovery, access, control, integration, and visualization of online sensors, the Open Geospatial Consortium (OGC) tested this idea in a December 2006 disaster response demo.
