Tire Pressure Sensor

[Terry Given]

I had a '61 Dauphine with tubular wrap-arounds that offered
substantial protection.

The first day in my new apartment in Boston, I was walking to the T and
saw a guy getting into a vehicle that was stuck between 2 others (all in
contact). I was curious to see what he did, so I stopped and watched.
Bang Bang Bang Bang Bang Vroom. I was astounded, but what else could he
do. A week later I was oblivious to such driving, its ubiquitous.

Cheers

In Europe some folks think they can't even live without ultrasound
parking aids in the bumpers. Oh man.

Infinately Preferable to VOLVO drivers who use the "rubber fenders" on the
bumpers to gauge the distance ... when parking *and* driving.

 

[Tim Shoppa]

In Boston, no ultrasonics need, they park by ear... clang, clang ;-)

Where I grew up, we called this "Park by Braille". In California they
have the bumpy dots ("Bot's Dots"?) on the highways too, for "Drive by
Braille" (probably a better analogy...)

Anyone who owned a Dauphine must be an experienced engineer; as we
gain experience from failure....

It takes a brave man to own a French car...

Hello Frithiof,

Infinately Preferable to VOLVO drivers who use the "rubber fenders" on the
bumpers to gauge the distance ... when parking *and* driving.

My first real driving after I got my license happened in Lyon, then
Madrid. Bumpers touched all the time and that was considered normal. If
something fell off in the course of action, oh well. The most important
part of a car seemed to be the horn, the least important the turn signal.

Sure, I wouldn't want to work on a DS21 where you can't even get a straw
between all the hoses and stuff. But I had a Citroen 2CV (the "ugly
duckling") for six years. It was good to me and got 50mpg on regular
gasoline. Even the new Prius can't do that and the 2CV engine was
basically a late 40's design.

I finally sold it in '68... never really had a bit of trouble with
it... but: (1) I added an oil filter assembly to it from a Caravelle
and (2), I always fed it distilled water, so the aluminum block didn't
get munged.

And it was the only '61 Dauphine in the world with a 50Amp alternator

A friend owns a Deux Cheviot. You forgot to mention that engine is
17HP on a good day. His car was in the parking garage under the
building and could not make it up the ramp with us on board.
We got out and pushed...

Oh, Heavens! Dauphine. Isn't that a Renault with two different horns, for
city and highway?

It isn't really my fault, but I looked up my Winnebago Le Sharo somewhere,
and discovered it has a Renault motor.

It does run, however, notwithstanding it needs new tires and various and
sundry to actually be roadworthy. ;-)

And I keep getting this nagging feeling that I should fill up the water
tank to prepare for Armageddon. Or at least for the next big quake. ;-)

Cheers!

They usually only came in 16HP, later they "upgraded" to 23HP and then
higher. Mine was 16HP. But it could climb all hills with a full load so
his must have had an engine or clutch problem. The 2CV had a really low
1st gear which helped on steep grades. The problem came when uphill on
the freeway and the truckers were about three feet behind you honking
their horns. That's where 16 horses just wasn't enough horses.

IIRC my Dauphine was 36HP.

When I moved to Arizona in 1962, driving by myself (the wife and baby
daughter flew), I never got out of second gear while negotiating Salt
Creek Canyon ;-)

I was being too generous, clearly....

The ramp up is just short of a 30 degree grade, I think.

He did OK once we got out; by then his engine was a bit warmer.
We still pushed a little to be sure he could not live it down...

Hello Spehro,


It already exists. One of the guys on the German electronics forum
(Oliver Bartels) developed such a system. I believe he also used to
race Formula One rods so he should know what he's talking about.
Unfortunately the pubs are only in German:

http://www.tyretronic.com/index.php?m=200202___AANDE_200201&language=en

In that article it is mentioned that the US mandates it already but I
doubt that.

I can see this for car tires although I check mine every other week.
But for bicycles? On mine I just sit on it and then I know. Usually the
pressure is digital. It is either ok, or it went kapoof.

Done with my assistance by Eveready (batt manufacturer) in the UK in the
70s coded Crystal controlled TX powering up every few seconds, inside
the tyre. Voltage controlled subcarrier prop to pressure
Sure its been done many times waiting for forcing function like
legislation .
