Last month we discussed how IMS and DMS are used for trace chemical detection. Now we consider how the two technologies can be used in tandem to achieve greater selectivity and sensitivity and fewer false positives.More>>

The first installment of this two-part series discusses ion mobility spectroscopy (IMS), the leading contender for fast and reliable detection of trace chemicals, and differential ion mobility spectroscopy (DMS), a related technology that provides faster, smaller and more sensitive sensors capable...More>>

Wildfires, river basins, tsunami alerts, and environmental risk management are just some of the projects using OGC's interoperability framework for Web-based access and control of sensors and sensor data.More>>

Integrating networks of sensors has been a goal for years, from the creation of device profiles and industrial networking standards through to the adoption of ad hoc wireless sensor and control networks. Web services promise to ease the integration of these disparate and distributed elements.More>>

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.More>>

Firefighters and HazMat workers have a very tough job. They're frequently in heavy gear, in unfriendly atmospheres, and working hard. Unfortunately, this combination of equipment, environment, and job stress means that frequently they're operating at the limits of human endurance.More>>

The federal government is spending billions on new Border Patrol agents and on sensor and radar networks in remote areas of the U.S.-Mexico border.More>>

New developments are advancing security capabilities for large facilities. For example, Vidient Systems, developer of intelligent video surveillance and analysis software, is partnering with Intergraph Corp., provider of spatial information management software, to integrate Vidient SmartCatch with...More>>

NIST researchers have devised a novel platform for self-assembling hierarchical surfaces in a fluid. Rather than mixing the components on a substrate and letting them dry, the investigators allowed them to mix and assemble freely in a fluid and then quickly froze them in place.More>>
