Assuming the compression didnt remove the high frequency, that still leaves the low sampling rate.
If you go and buy an acoustic mosquito repellent, the tone isnt nearly as harsh as that.
1: The tone is compressed with mp3. 25kHz isnt supposed to be even representable with that format. MP3 drops frequencies at 16kHz and above, right? 2: You cant properly represent a 25kHz tone with 44.1kHz sampling without distrotion. For all we know the real tone may sound like Mozart.
Sure, there is no problem updating firmware. Firmware gets upgraded all the time on loads of products. The problem is that the hardware for the newer BD players might not be in the older ones. I'm no expert on BD, but I do know that you cant upgrade a 4-cylinder engine into an 8-cylinder engine by just plugging in a new ECU (the firmware).
I would hope that Samsung has a valid reason that they cannot possibly upgrade. At least they arent sending its customers up a creek from sheer apathy.
I got my mac so that I wouldn't have to deal with the eternally beta Linux software situation. I want things to work I take it you aren't running the latest QuickTime software, huh?
GM had cars during the 80s that got better fuel economy than most hybrids of today (50-60 mpg, with carburetors no less). Few wanted them then and few want them today.
E10/85/100 causes damage because the ECM wont compensate for the extreme timing advance required on such a small compression ratio that ethanol fuels require due to their octane ratings. Thus, you have a bad burn, poor fuel economy, poor throttle response, and you can easilly overheat the catalytic converter, and turbo if equiped. This isnt even addressing the fuel line and pump issues, nor the chemical reactions on the metals used internally.
As for the WW2 plane engine overhaul, water was injected to increase the compression ratio, and thus power, normally at takeoff from short runways. There was a string keeping the carbs from opening all the way. If the pilot pushed the throttle open rather hard, the string would break and the carb would open completely, giving several hundred more horsepower for only a few minutes. The stress on the engine was so great that it was too dangerous to fly them again without rebuilding them.
On an only distantly related note, electric brakes are set to dramatically increase the safety and reduce the stopping distance for trains. Currently the airbrake system takes many seconds to deploy and react down the length of the train, whereas electric can cause the braking to begin at the same time on each car. And airbrake systems are completely incomparable to hydraulic systems. Consider how much pressure at the pads you need to stop a train weighing thousands of tons quickly. Now consider that to build that pressure over a very large area consisting of air ducts and brake cylinders, it should come to no surprise that air brake systems are slow.
Now compare this to any modern hydraulic system which is quicky to react (when properly designed) primarilly because the fluid doesnt compress under the extreme pressure required by the break system. The only problem is cost of the entire system as a whole. When you consider that most trains use electricity as their motive force, it should come to no surprise that electricity is in no short supply, therefore it makes sense, in a way, to use electric brakes.
Contrast this to vehicle brakes and this becomes an exercise in stupidity. There is no advantage whatsoever in using electric brakes over hydraulics. ABS works just as well in hydraulic systems as it does in electric. Not only is it ridiculously unsafe, it also drags the engine using it, requiring lots of torque (which can stall a small engine at idle) and larger alternators. Contrast it to the modern hydraulic system, your foot provides the power, plus a boost provided from engine vacuum which is in no short supply in any reasonable driving scenario.

A well regulated power supply required to stabilize a millivolt source with any semblence of accuracy is far too bulky and expensive to ever be considered. Beyond that, the noise inherent in the wiring would give lots of false readings at all operating temperatures. The ADC in the measuring circuits are also not standardized much below 1V, if there are any manufacturers that produce them at all; lets not even consider the exceptionally poor resolution they would give.
Thus, such a system would be extremely cost prohibitive for next to no safety gains.

Imagine how some of those shareware authors feel when they see cracked copies of the stuff they worked to build on everyone's computer just because someone didn't want to throw them a $49 registration fee. And when it comes to movies/music, there's lots of broke actors for every over-the-top-rich Brad Pitt.z` Software piracy and music piracy are two extremely different things.

What you say is very true. However, you forget to mention the element of administration. Engineers can only work with tools, knowledge, and expertise they have. The administration overseeing the project cant always accomodate everything the engineer wants due to budget restrictions or sheer ignorance. Sometimes the design itself might be flawed in a way that was unforseeable in the past and it would then be uneconomical to go back and fix the problem at the present or the managers cant allow you the time to go back and fix it because of deadlines and whatnot.
Thankfully the "make or break" moment of a project doesnt always rest on the shoulders of the engineer.
If you had a Faraday cage around your electronics, there wouldnt be a pulse to disrupt your signals, differential or otherwise. You didnt address why a Faraday cage wouldnt work at all, but rather showed why noise cancellation might no work against the microwave weapon.
Nothing to do with a Faraday cage, mate.
One concern with the device is that it could cause an accident if a car is disabled and a driver loses steering control. This isnt a problem for most of the vehicles on the road today since they use primarilly hydraulically actuated power steering, but you can still steer even without hydraulic pressure. Same thing with standard rack-and-pinion and recirculating ball steering systems. For these three types, only a grandma that doesnt expect to loose hydraulic pressure will have any serious problems controlling the car.
However, steer-by-wire systems are quickly coming into play in America, especially on some of the lower-end GM products. Now I'm no GM engineer yet, but from what I gather the steering system is either on the GMLAN high speed bus or it has its own bus but still gets data off GMLAN.
Now suppose the ECM stops giving out speed information on the GMLAN bus. Hopefully there is a contingency plan in the steering logic so that you can still have some steering I/O even without the vehicle speed information, but if the output isnt on its own bus, I cant say I'd want to be in that car.
Then you should have enabled BSODs:
By default when WinXP encounters a system failure, it reboots without warning. The setting that controls this can be changed: Control Panel/System/Advanced/Settings (Startup & Recovery)/System Failure/Uncheck-Automatically Restart. To view the event log: Administrative Tools/Event Viewer or Start/Run/eventvwr.To bypass the BSOD altogether and enable the instant "Auto Reboot" feature: Start/Run/Regedit http://kellys-korner-xp.com/win_xp_restart.htm
Hmmmm, I have a mass of air leaking from a space ship. My detector mechanism is outside in the vacuum. I wonder how I could detect this escaping air? Maybe the detector will announce that it hears something when it passes through the mass of air? BRILLIANT!
