TSA say no to powerless devices

So by this new rule is the TSA admitting that they do not, and probably never had, a reliable warm and fuzzy method of accurately detecting explosive devices?

TSA – Say No to Powerless Devices

That's brilliant! What would TSA agents say about USB portable power supplies, which are essentially just battery cells with some electronics and no GUI?

TSA would be clueless. In the 1990s I worked with the Psion Organiser, a handheld computer that was ahead fo its time. Airline security was told it was a calculator and it was never questioned.

It's a silly rule. If the device is unpowered, you must pack it into your check-in luggage. Since the new rule is aimed at suicide bombers, wouldn't the device be just as effective being detonated with a timer in your check-in?

"If the device is unpowered, you must pack it into your check-in luggage."

The exact wording of the TSA announcement reads "Powerless devices will not be permitted onboard the aircraft," which suggests that such devices will not be allowed in check-in baggage either.

in that case, all suitcases, and their contents, need to be inspected before check-in. That is a huge logistical effort that I doubt the airlines and airports are prepared for. It is further complicated that you may check-in your luggage at a connecting flight before taking the overseas flight. The connecting flight isn't restricted, and may not be the same airline as the US-bound flight.

There seems to be 3 news in 1 article unless I missed the connection.


The new TSA rule could cause a lot of problem to business travellers. With the rule, who can bring a USB drive? I hope the rule is for short term and will be removed as soon as they find a better way to inspect explosives or other hazard materials.

How about transparent packaging?

I think it is high time to make the casings of all electronic devices from transparent material, so that there is no room to suspect what lies inside.

This is a new challenge for the case designers and think such solution will be more reliable than requiring to power up each electronic device to make sure it is harmless.

Many a electronic devices do not have displays or even the power-up LEDs. so the current regulation does not solve the problem 100%.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
