I have to wonder about a comment I think James may have made regarding possible cell phone or other electronic interference causing problems with automobile computer systems and sensors. If it could be shown that electronic devices do or can cause hiccups in these systems, whose responsibility is it to fix that? We already know that airlines forbid use of some electronic devices while in flight due to possible interference with navigation systems. This might be a valid point that's worth investigation. It could be that some automobile systems/sensors are more likely to be affected than others and it might be that some electronic devices are more apt to generate signals that affect automobile systems. Obviously a poorly designed cell phone isn't going to result in death but, if it could cause a car wreck, I'm not certain we should jump to blame the car and expect a re-design anymore than we should expect bullet proof glass because someone got killed in a gang war crossfire.

Lots of stuff

........ also like GPS and satellite radio.

Are those screens to entertain children like a vCR or do they show live TV?

There was a time cell phones could open garage doors up and down a street, if I recall c orrectly.

Something to think about.

Along that line...

Along that line, there is a laminated card attached to my electric wheelchair that warns about operating things like cell phones. It says in part:
"Radio wave sources may affect power wheelchairs/motorized scooter control." and "If unintended movement or brake release occurs, turn the powered wheelchair/scooter OFF as soon as it is safe.".

I haven't "snoped" it yet but I expect to be hearing more such anomalies. I already know my employer supplied PDA causes interference with some devices I work on and will produce a buzzing noise in land line phones and speakers. I've even heard it create that buzz in PA systems in some stores.

RF noise/sources

by Willy Mar 11, 2010 12:08AM PST

There are times when I work on wifi setups to include anything that's remote controlled have weird issues. I try to explain, really there's nothing I can do but move the PC elsewhere or try to shield certain areas. So far, I've found no shielding that can be added as it were to help in these matters. Thus, a wifi printer may even now and then spit out a paper or print weird stuff when no one is around. This problem is common in apt. or hi-density living. Now, you say, why doesn't this happen more often in offices? Well, it does but it's taken for granted and/or not as effected as the PC gets used alot more
to include also that some better grounding is in use. While PCs in general are shielded by being housed in a metal case, they are also grounded as part of its make-up. They also tend to considered powered by a more protected circuit though not immediately apparent, it just is. However, any RF source that's close or just a leaky source is bound to effect something. Anything electronic or RF based generates noise and if not build-in shielded will sooner or later effect something and what that is, is the weakest link or closest item that can be effected. Consider the warnings on microwave ovens to anyone having a pacemaker, go figure. A small electronic device near a device that uses 1000W or better to cook a meal. go figure.......
