[SystemSafety] ROHS and Safety critical applications

Mon Jan 23 22:38:22 CET 2017

The EU directive ROHS (Restriction Of Hazardous Substances) cover almost all
kind of Electrical and Electronic Equipment (EEE). The scope is to reduce
the amount of lead, Mercury, Cadmium and some other substances. This means
that most EEEs have to be produced with lead free components and solder.

As far as I can see, there are no exemptions for safety critical
applications. ROHS applies.

I would like to hear from you guys doing safety critical design, that you
have the same understanding.

Thanks .

Cheers

Emne: Re: [SystemSafety] Apple being sued for illegal use of Facetime

I’m not so sure that’s a great idea. Our new Mondeo has a system to that is
supposed to detect “driver fatigue”. The rate of false positives is
positively maddening and it took ages to find the tiny little “OK” button on
the steering wheel so I could get rid of the &^%$£ stupid message in the
middle of the dashboard display (an LDC simulating analogue dials).

The number of little buttons (and I mean little as in small) is in itself is
positively maddening...

If you are going to follow this line of thinking, it seems to me that the
car manufacturers are more in line for criticism than the phone
manufacturer. It is the car that is the “injuring device”, not the mobile
phone, so it makes more sense to install protection in the car than it does
to put protection functions in the phone. 

Going back to PBL’s original argument, the problem is the distraction of
drivers from the primary activity of driving. I’d have thought there was a
case to expect the car designers to monitor that the driver is paying
attention to the road. This is at least somewhat analogous to putting
kickback protection on the table-saw. 

There are already designs for systems to monitor drivers by observing their
direction of gaze and head-attitude. I came across it in systems designed to
detect drunk driving. I’d be amazed if no-one has improved them to monitor
drivers failing to pay attention to the road for other reasons.

In regards to this 

> Are manufacturers responsible for inhibiting illegal use of their
products? 

You may find this interesting. 

Table Saw Accident Victims May Qualify to File a Lawsuit and Seek Settlement
Compensation 

"Despite safety technology that could prevent many of the most serious table
saw injuries, the manufacturers of these tools have failed to equip them
with their products. Table saw users who suffered amputations, lacerations,
avulsions, or other injuries may be eligible to file a lawsuit against the
table saw manufacturer and receive compensation." 

"Since 2003, manufacturers of table saws have had access to flesh-detection
technology called SawStop, which would prevent amputations and injuries to
human flesh. However, these companies have chosen not to add the technology
to their machinery. The reason? Adding this vital safety feature might
increase the expense of production – a cost they would ultimately pass on to
the consumer. What manufacturers don’t seem to consider is that the cost of
making safer tools might still be less than money spent in table saw injury
lawsuits."
