181.0. Again, holding ~1#, I still measured 181.0. Then, when holding
~1.5#, apparently past the programmed hysteresis threshold, scale
reported 182.5.

Do you think that this behaviour would result if the ADC resolution is
coarser than the display resolution, for example the LSB represents 1.5#?
Or maybe the ADC has missing codes. This wouldn't require tricky
programming, just a bad ADC.

A balance scale at a gym I used to frequent had about a 5 lb
difference at the 200 lbs mark, depending on whether you moved the big

small weight to the 50 lb mark.

I have a Taylor bathroom scale, with a 1# hysteresis. I weigh myself

Why is it then that the current flowing through a fully forward-biased
diode is called diffusion current instead of drift current? Under this
condition, is the majority carrier current (which predominates) not
driven by the external forward bias (thereby eliminating the need for
thermal excitation associated with diffusion)?

defending myself in a bar-fight... That said, I don't need remarks

Having read the rest of the thread, so far, I think what I'd do if I
were in your shoes (easy for me to say, since I'm not) is to call
whoever's on your case and let them know that since they can't supply
you with range data what you're planning on doing is walking away
from your confinement area until the telephone light goes on or the
range light changes color, (I'll bet that's what happens when you
leave your confinement area; the thing calls the cops and sends its ID
so they'll know who it was) and then go back in.

If they think that's a bad idea, then ask them to send a cop over so
that he/she can take the walk with you just to make sure you're not
trying to do something funny.

Understood. But I think we may be barking up the wrong tree, seeking a
technological solution to a policy problem.

Sounds like your mailbox is in bounds, according to the terms of your
confinement* so just go ahead and fetch your mail; you'll learn soon
enough whether an alarm gets sent. In any case, you'll be in your house
when the police arrive, right?

*If the mailbox is out of bounds, then you would be looking for a way to
beat the machine, so based on what you said, it must be in bounds.

Let me rephrase my last post for you St. John. 'ONE' of my points is
that I've not been sufficiently informed of the terms of my program,
particular to the range limitation.
Click to expand...
That sounds very unfair to me.

The other issue is as to whether or
not the range can be increased. I can only believe that if the range
CAN be increased, then the unique circumstances pertaining to my rural
environs would justify it.
Click to expand...
Agreed.

The problem is that in pracice all sorts of things effect the range of radio
communications. It's a problem for the makers because in order to guarantee
say 300ft in all conditions some people will find it works over a much
longer range. Take CB radio... With the right conditions you can either get
10 mile range or half way round the planet. Those conditions are out of the
control of the manufacturer. Things like the height of the base station
above ground will effect the range as might simply watering the lawn or
atmospheric conditions at different times of the day.

I want to know something of what I speak when addressing the Court.
Click to expand...
Best ask the court to specify a distance in feet. Tell them how far it is to
the post box or better still give them a site plan and ask them to mark the
boundary. Then you might have grounds to complain if it doesn't allow you
that range.

Just one bit of parting advice: have a lawyer represent you in dealings
with the court/authorities. What you're about to get stuck to like Tar

OK! So I see now that the "75-300" foot range is the "range of the
range" if I understand correctly? I was thinking that the unit could be
set for a specific distance 'within' THAT range... DUH! Am I on the
right track here?
Click to expand...
Yes. Whoever sets up the equipment can adjust the range so that it restricts
you to as little as 75 foot or as much as 300ft. However as I said before
its not like setting up an invisible curtain - it's not precise. Ever
listened to a radio station in your car and driven out of town - it fades in
and out for many miles. It's hard to define a point at which you are "out of
range".

Yes. Unfortunately, since the thing isn't a transponder and is merely
an RF transmitter sending an RF carrier (perhaps modulated) to the
receiver, what's happening is that the receiver is responding to the
_amplitude_ of that carrier to determine whether or not you've
overstepped your bounds. Unfortunate in the sense that just about
everything will affect the amplitude of the received signal and the
range setting will, at best, be a crude approximation.

I think that these things are designed to detect when someone is gone
_permanently_ and to give the cops a heads-up fairly quickly when
that happens. I read on the web somewhere that there's also a delay
setting, ostensibly for momentary signal fluctuations below the range
set threshold which keeps the thing from sending false alarms.

Or blowing your leg off if it's one of the ones with an explosive
charge in the "bracelet" ;)

Were there any curfew conditions imposed on your sentence?

Depending upon the sentence, some people only have to remain indoors
during defined hours, such as between the hours of 6.00pm - 6.00 am
but they are allowed to leave home in order to attend work. If you do
have a job then you must be allowed to go out of range during daylight
hours.
