Independence Day Fireworks punted by the Great Recession

As the Great Recession drags on and on, more and more municipalities are being caught by the cash crunch. This year, a major casualty of shrinking budgets may be the traditional July 4th fireworks celebration. Towns all over are canceling or getting creative.
"It's becoming harder and harder to justify," she says of the $20,000 event. "The tax dollars only go so far, and it's one of those expendable items."

Other places such as Birmingham, Ala., may scale back the festivities as well unless they can attract more corporate sponsors. The Independence Day celebration in Moorestown, N.J., across the Delaware from Philadelphia, was canceled for the second year in a row. Monterey, Calif., suspended its Fourth of July festivities because of "budget constraints and ongoing safety concerns regarding the Fireworks Display," according to the city's website. Maplewood, Minn., Mayor Will Rossbach told the Pioneer-Press that it no longer made sense to pay about $19,000 for the town's 30-minute fireworks display while struggling to maintain more basic city services.

In another strategy, Morris Plains, N.J., saved its traditional July 4th fireworks display -- and some of its tight budget -- this year by holding it on Saturday, June 26, instead.

The origin of the iPhone 4's signal problems?

Fans of government intervention and regulation believe that it is possible to create complex guidelines for businesses which give us only benefits and no detriments. But the reality is that every government regulation has an unintended consequence and one antenna designer is suggesting an FCC regulation is behind the reported iPhone 4 antenna issues. It may explain several other mysterious decisions behind Apple's designs in previous generations.
Just about every cell phone in current production has the antenna located at the bottom. This insures that the radiating portion of the antenna is furthest from the head. Apple was not the first to locate the antenna on the bottom, and certainly won't be the last. The problem is that humans have their hands below their ears, so the most natural position for the hand is covering the antenna. This can't be a good design decision, can it? How can we be stuck with this conundrum? It's the FCC's fault.

You see, when the FCC tests are run, the head is required to be in the vicinity of the phone. But, the hand is not!! And the FCC's tests are not the only tests that must be passed by a candidate product. AT&T has their own requirements for devices put on their network, and antenna efficiency is one of them. I know because I have designed quad-band GSM antennas for the AT&T network. The AT&T test similarly does not require the hand to be on the phone.

So, naturally, the design evolved to meet requirements - and efficient transmission and reception while being held by a human hand are simply not design requirements!
I can confirm that I have seen this issue with my iPhone, and it now appears Apple has acknowledged the issue. But it is interesting to see how it came about, and the pressures that may have justified it. In the meantime, many users are looking into cases to alleviate the issue.
