This post extends on my post of last week: How Full-Body Scanners Work – and Fail The aim of this post is to explain x-ray backscatter scanning in further detail by examining a few of the patents that describe how x-ray backscatter full-body scanners work. In order to receive a […]
It’s been tough to keep up with all the news on body scanning developments. Here are a few items from the last few days: Your Morning Cup Of TSA Horror – The Consumerist. Representative Holt Continues to Question Science, Effectiveness of TSA Full Body Scanners. Hat Tip: Mark Frauenfelder, BoingBoing […]
For over fifty years, Ayn Rand’s best selling novel, Atlas Shrugged, defied attempts to capture it on film or video. Now this past summer, a team led by John Aglialoro completed shooting on the first part of a planned Atlas Shrugged trilogy. Three weeks ago, ÆtherCzar presented a preview of […]

Today’s post is a mix of recent updates and older background posts on full-body scanners. Kevin Poulsen writes in Wired that New York City may forbid TSA from using body scanners at New York airports, including JFK. There’s a summary on full-body scanners in New Scientist. Here’s an older piece […]
A couple of days ago when I explained How Full-Body Scanners Work – and Fail, I didn’t mention any potential health risks because millimeter wave signals are inherently non-ionizing and the power levels associated with the potentially ionizing backscatter X-ray scanners seemed at first glance to be negligibly small. However, […]
A few recent items of interest: St. Croix Systems is hosting a free 5-part educational webinar series on asset tracking using Real Time Location Systems. Four of the leading RTLS vendors in healthcare will present their solutions to give the audience a better understanding of how RTLS can support effective […]
TSA has been introducing full-body scanners to perform a virtual strip search of air travelers. Although technically travelers have the right to opt out, the TSA discourages this behavior with aggressive and invasive pat-down searches. Initially, TSA denied punitive pat-down searches. Then they acknowledged testing a “more aggressive pat-down technique.” […]
When I first heard about “Blinky Bugs,” I thought they’d make a perfect craft project for my twin girls’ sixth birthday party. Then I took a closer look at the complexity and delicacy of the assembly and realized it was beyond the skill level I could expect of my girls […]
John Brandon, writing at Digital Trends, features my company, The Q-Track Corporation, as one of “Six tech start-ups that could change the way we live.” Q-Track’s Near-Field Electromagnetic Ranging technology provides the “indoor GPS” to bring location awareness to the most difficult industrial RF propagation environments. The piece is a […]
An American engineer must overcome the objections of environmentalists as well as the machinations of terrorists to complete a tunnel under the English Channel on time and under budget. Robert Byrne’s The Tunnel (1977) is an action-thriller in an engineering setting. This was Byrne’s first engineering novel. Writing in Behold […]
Last week, Joshua Brustein reported at the New York Times that “Location-Based Services Have Not Caught On,” citing a Pew Center report that shows use of such services has declined from 5% to 4% over the last six months. The most current survey had a +/-3% margin of error. I […]
Steven J. Crowley once again has an update on Experimental License Applications before the FCC. A couple of highlights include: “Zimmerman Associates filed an application (with supporting exhibits) for special temporary authority to test the capability of using a full polarimetric UWB radar system for identifying roadside bombs and improvised […]
Cracked.com has an entertaining and enlightening report on five popular safety measures that don’t make you any safer. It’s so hard to think logically about safety. We figure that any time our health or the safety of our children is at stake, it’s better safe than sorry. Our safety is […]
AeroScout announced yesterday that it has secured $16 million in venture financing to capitalize on the strong demand for its Real-Time Location System (RTLS) and to continue to accelerate the adoption of its Wi-Fi RFID solutions. New investor Evergreen Venture Partners led the round, and all of AeroScout’s existing investors […]
Frequent ÆtherCzar visitors will have picked up on my appreciation for Robert Byrne and his engineering novels. If you’re not familiar with his work, the first post below is a good place to start. Engineer as Hero: The Novels of Robert Byrne Book Review: Skyscraper by Robert Byrne Book Review: […]
Time for more wireless updates: Here’s a great article about the British precursor to LORAN: “GEE.” GEE was one of the first implementations of the “Time-Difference-of-Arrival (TDOA)” concept used in some modern RTLS implementations. A simple explanation of Ekahau RTLS: “The Perfect Pairing of RF and IR.” Whatever happened to […]
The movie version of Atlas Shrugged (Part One) completed a five week shoot in July and is now in post-production. Producers John Aglialoro and Harmon Kaslow began filming just days before the rights to the story would have reverted to the Estate of Ayn Rand. The producers changed directors just […]
ÆtherCzar briefly mentioned this last week, but it bears repeating in further detail. When you log in to Facebook, Twitter, or other such sites over an unsecured WiFi network, you are broadcasting your identity and login information in a way that anyone else on the network can detect and exploit.

I’ve updated the top-ten list of most popular ÆtherCzar posts in the right column to reflect October’s page views. Some old standards remain popular, like my August post: Einstein’s Nobel Prize: Proving Cell Phones Can’t Cause Cancer. And, perhaps in anticipation of next year’s Atlas Shrugged movie, my Chronology of […]
Time once again to clear out the update queue: Steven J. Crowley explains the many facets of what’s called “4G” technology.
