Electronic Faucet

Hello Jim,

That's true. But even in the days when I had to that didn't bother me much. An automatic can really throw you a curve when it's icy out there or when you have to crawl up a steep mud "road" in heavy rain. Not much of a concern in Phoenix, of course :-)

Regards, Joerg

Probably a substandard BOR circuit.

Good for hygene - remember that people turn the tap on with hands that have just been on thei privates etc - so you wash your hands clean, then touch that dirty tap handle to turn the water off. Was/is a big problem for infection control in hospitals who haven't fitted foot or electronic on/off taps

I thought hand washing was for employees only. j/k ;-)

But seriously, as I'm washing my hands, I usually also wash the tap handles; it only takes a few seconds. The problem is with some sinks when you rinse the soap off the handles, the water doesn't always drain back into the sink and it can make kind of a mess. Also, I sometimes use my elbow to dispense the paper towels, then use the paper towel to open the door. Ah, clean hands!

At MIT they taught us not to piss on our hands ;-)

Its really sad that you had to wait till college to learn that.

Me too

That's just a line out of an old Harvard/MIT joke...

Two guys go into the john (one from Harvard, one from MIT), and take a leak.

When they're finished the MIT guy heads for the door.

The Harvard guy remarks, "At Haaah-vaaahd they teach us to wash our hands after we urinate."

To which the MIT guy replies, "At MIT they teach us not to piss on our hands."

Battery-operated water control devices generally use a pilot type of valve, i.e., a valve with 2 fluid circuits, one small and one large. The small 'pilot' circuit has a tiny solenoid valve that doesn't require much current. The small flow in the pilot circuit is used to operate a much larger valve. It's a kind of hydraulic amplifier, using the water pressure as a free source of energy. The longest-life devices use magnet-biased solenoids, so the pilot solenoid is pulsed on and off. The Sloan Optima series is rated for 5 yrs or 50K flushes, and it's an honest spec. The power budget for the 4AA cells was divided about equally among these consumers: CMOS microcontroller, photoelectric sensor circuitry, solenoid driving, and battery self-discharge. Most of the reliability issues with electronic water control is due to particulates in the water supply that clog the tiny pilot circuits. There are several important patents relating to how to design the internals such that they don't tend to clog. The ubiquitous Sloan Royal's success was originally based on its patented centrifugal inner chamber, that forced larger particles in the water away from the pilot orifices. Paul Mathews

I heard the same joke, but it was about a Marine and a Navy Guy. I forget which was which.

Likewise but with Boeing and McDonnell Douglas.

If travelling to certain Asian destinations you might care to clean the whole sink area carefuly before using it yourself.

First step is to make sure your laundry is all caught up. It may be a while before you have a functioning washing machine again! :-)

I've been driving various Jeep wagons for the last 25 years. All had automatics and all gave me all the manual control I needed including hiway, mud (what we call "loon s*it" in this country) and loose desert sand. Convenience of the automatic in city and paved hiway and control when needed.

Army & Air Force, and it was the Air Force guy who didn't piss on his hands. ;-)

I once saw a very cook toilet tank in Japan - the tank top was a basin, with a hole in the bottom, and the fill pipe was a spout like a water faucet, presumably so you could wash your hands right there, and then your hand-wash water would go into the tank for the next flush.

Now _there's_ a water-saver toilet! ;-)

I learned long before I was college age! ;-D
