Putting Measurement into Perspective   November 30, 2006

What often eludes us, but is worth keeping in mind, is that measurement itself is a process and can be treated as such. Calibration and traceability are parts of that process, and all have the same fundamental limitation as all measurements: Uncertainty Rules!More>>

Not an Either-Or Proposition   November 29, 2006

The debate over batteries vs. power harvesting in wireless sensor applications is fermenting just below the surface as the RF technology gains broader acceptance. The mistake some of us have made is to look for the supremacy of one technology in all instances. That will not be the case.More>>

Large Scale Security Approach Has Larger Implications   November 28, 2006

Securing large facilities-including public spaces-from so many threats seems a daunting task. Besides new technology, new business agreements are pushing forward developments to aid the effort. A couple of recent announcements illustrate this point-and have implications for more modest security...More>>

Putting a Spike in the Spokes   November 27, 2006

The charms of the SUV continue to elude me. Trying to peer around some monster bulk parked at the corner of School and Grove streets here in Peterborough when I want to turn right without getting T-boned is a sweaty proposition. It's worse after a winter storm, when snow banks along the curbs mean...More>>

The Coalescence of the Health Care-Sensors Market   November 21, 2006

For years, the health care industry, medical research organizations, and high-tech manufacturers have developed and tested sensor-based devices that greatly enhance the care that can be given to the sick and elderly. What has been missing is a market that can support the cost of extensively using...More>>

Limping Robots   November 20, 2006

You know, normally if we see something limping (or are limping ourselves), that's a bad thing. But in a recent development in the robotics world, a limping robot represents a significant advance.More>>

RFID: Not Just Vanilla Anymore   November 17, 2006

More and more, RFID tags-which traditionally carried simple identifying information-are being paired with sensors. And lately they're being enhanced by other technologies, too, for sometimes-surprising effect.More>>

The Lights Are Out, But Everyone Is Home   November 16, 2006

Our culture is full of conspiracy theories, involving the Kennedy assassination, extraterrestrials, and RFID. We all take these with a grain of salt because we are aware that only kooks place any stock in them. But there is one that I fervently believe: Both my wife and daughter are agents of the...More>>

RFID Scanning for Fires   November 15, 2006

Here on the east coast the weather is dank and damp and getting colder. For our antipodean friends in Australia, however, summer is just beginning and with the summer heat comes the threat of forest fires. A new take on RFID may give the firefighters a quicker way to spot blazes.More>>

Two Cheers for NASA   November 14, 2006

Only two cheers today, but one’s pretty loud and the other’s well above audible. First, NASA will save the Hubble Space Telescope. Second, NASA has established a venture capital entity designed to direct government research contracts (and funds) toward small high-tech companies with...More>>
