Are you calling 911 on your cell phone because you need emergency assistance? Your cell phone provider has to be able to locate your phone to aid emergency responders in finding you. The current standard, Wireless Enhanced 911 or ‘E911″ Phase 1, requires cell phone providers to be able to […]

After a famous wooden roller coaster injures passengers with the violence of the ride, an engineer hired to evaluate new safety modifications must analyze and diagnose a disturbing series of malfunctions before the grand re-opening. Thrill features an engaging cast of characters: the stalwart and straightlaced midwestern engineer, the mad […]
Periodically, I like to pass on interesting items that don’t warrant stand-alone posts. Here’s today’s list: ThingMagic continues their series on 100 innovative uses of RFID technology in 100 days at http://rfid.thingmagic.com/ Where, Inc., a location-based ad network, buys Local Ginger. More from the NYT. The Location-Based Services (LBS) market […]
Few novels capture the drama, the passion, and the excitement of engineering. To do justice to the subject, the author must be conversant with engineering science and practice. In addition, the author must write with sufficient power and clarity to make the relevant technical details clear to a non-technical audience […]

On 24 September, 1944 Operation Market Garden was capturing attention, as the Allies attempted to capture the “bridge too far” at Arnhem. Also that day, my grandfather, Paul Farnum, died at the 32nd Evac. Hospital of wounds received 21 September in the fighting for Luneville. He was buried at U.S. […]
Here are some updates: Not only does Steve Crowley have his monthly review of experimental license applications at the FCC, he also draws attention to a review of the proportion of lawyers, economists, and engineers at the FCC compared to other country’s telecommunications regulatory bodies. MP Antenna partners with TESSCO […]
Some Georgia Tech and University of Washington researchers have developed a scheme to use home wiring as an antenna for low power sensors operating at 27MHz. Patel’s team has devised a way to use copper electrical wiring as a giant antenna to receive wireless signals at a set frequency. A […]
The 1st and 3rd Battalions were ordered to attack in the vicinity of the railroad overpass and to clear out resistance in houses beyond the overpass. At noon, the defence of Luneville was put in the hands of the 313th Regiment. Acknowledging the severe resistance of the enemy, the 315th […]
In 1898, Sir Oliver Lodge (1851-1940) patented the first syntonic or tuned radio system. Ironically, the very patent that inaugurated this fundamental concept of narrow-band, frequency-domain radio also disclosed some of the first ultra-wideband (UWB) antennas: As charged surfaces or capacity areas, spheres or square plates or any other metal […]
By midnight a treadway bridge has been constructed across the river at Lamath. Except for occasional enemy fire, the night was quiet. At 13:30 the Regiment moved out of Germaniel. No enemy contact was encountered by the column on the march to Luneville. The 1st Battalion was ordered to proceed […]
This piece from Popular Mechanics on the evolution and development of the Leatherman Tool inspired me to draft this post about the evolution of one of my UWB antenna designs from conception, through prototyping, and finally to production. This paper describes the end result, and the design is covered in […]
Traveling through Charmes, Einvaux, etc. the 313th Regiment arrived in the vicinity of Landecourt about 04:00, today 19 September, 1944. At 07:00, the 1st Battalion was ordered to attack west to the highground just west of the Meurthe River. The 1st Battalion encountered enemy fire, but captured the high ground […]

The 313th Regiment has been in Division reserve for 3 days. This afternoon, 18 September, 1944, the USO with Bing Crosby put on a show. During the performance, the 313th was ordered to prepare to move. At 18:30, the Regiment was motorized and moved out.
Radioactive decay rates are generally thought to be invariant constants of nature. Some minor temperature dependent effects have been observed, but even those remain elusive. Now however, researchers at Purdue and elsewhere argue that they have detected solar influences on radioactive decay rates. They claim the decay rates of certain […]
Technically this is more about antenna maintenance than design and engineering, but let’s not quibble. The video embedded below shows climbers ascending a 1768 ft antenna tower explaining the features of the antenna design. I feel acrophobic just watching it. But talk about a workplace with a view – in […]
The Ideal Scientific Equipment Company, of course! With an inventory including magnetic monopoles, frictionless planes, inertialess pulleys, and more, textbook results can finally be guaranteed for most any physics experiment.
A few quick updates, while I recover from Wireless Wednesday on Twitter: New Scientist explains the history of complex numbers in a fascinating piece, “Putting the ‘i’ in iPods.” But since the iPod is more an accomplishment of engineering instead of physics, shouldn’t it be called the” jPod?” To learn […]
The 313th Regiment was placed in Division reserve just northwest of Charmes, today, 15 September, 1944.
Yesterday’s post on Peter Massey’s Antenna Engineer’s Guide prompted me to think about about why I love antenna engineering. Massey is correct that antenna engineering does provide interesting and varied work, good pay, and job security. But one could say the same about many other jobs. Here’s a slightly edited […]
Today, 14 September, 1944, the 313th Regiment finally secured Poussay at 11:00. The 1st Battalion moved on to capture Mirecourt in the afternoon, while the 2nd Battalion captured Ramecourt. The 313th Reigment captured Poussay today, 14 September, 1944. Source: Hugh M. Cole, U.S. Army in WWII European Theater of Operations: […]
I recently ran across a fantastic introduction to antenna engineering as a profession. Peter Massey compiled his Antenna Engineer’s Guide with an eye to helping students evaluate on antenna engineering as a career choice. Why chose antenna engineering as a career? Here’s Dr. Massey’s analysis: Interesting varied work. In many […]
The 313th Regiment resumed its attack on Ambacourt and Poussay this morning, 13 September, 1944. The 3rd Battalion overran the town by 10:30 but was encountering such resistance that the 1st Battalion was ordered to attack from the southeast and the 2nd Battalion from the west.
