mobi`safety/phone:
. if you have an accident, it might be necessary to have voice command
of the cell phone;
at the very least it should be tethered to your body so you know where
it is after things got scattered .
tougheners
7.2.24:
efficient multi-door lockup
. can have multiple doors without the expense of many locks,
by unlocking one door to unlock the others from the inside
. the primary reason for having multiple doors
is that the sewage tank needs a locked door to protect from vandals and
pranks
and it`s location is near the back while the primary door is in the
front
7.2.24: vandal
ready
. if any spills (or successful pranks),
the lockbox needs to have protection from getting electronic equipment
wet
. everything should be on pallets that give liquids a chance to find
the drain on the bottom
. if mobi gets turned on it`s side, or top,
the most sensitive equipment should be packaged to take that .
6.12.13: collision
avoidance
. should plan for car collision,
can avoid right-side hit by replacing busy left turns
with a right turn followed by a u-turn in some quieter place .
7.2.17: escape hatch
. bottom hatch should be quick release, for an emergency back door .

7.2.28:
optimizations
. while experimenting with modifications I found some days ago
that
the ear pads could be popped off the muff
`shells
. this compact version was pressing on my ear`cartilage until I removed
the foam from behind the circuitboard
. now I'm looking again for ways to get the speaker closer to my ear
. the [vol + power] switch does come out, but the mic is glued
(you might be able to undo the glue,
but I'm looking for some way to make reversable modifications
so I can still get help under warranty)
. the best pro-ears access is removing the units to a separate
box
and using the holes left by the volume controls
. until I find a box though, and figure how to deal with the mic's
being glued in place
I found it best for not having ears pressed sore
to change the position of the circuit board,
rotating it to have the speaker close to ear canal
and have batts not near ear`s thick-cartilage part
. in this rotated position, the circuitboard can be much farther from
the ear,
but it's also then much closer to the mic,
and makes a feedback sound if foam is not placed between mic and
circuitboard
. the foam is pressed tightly and doesn't push the circuitboard into
the ear
because the c'board can slide under the pegs that anchor the headband
. I was suprised about the feedback problem;
because, the mic appears tightly sealed from the inside of the muff`s
shell
with a sort of very-sticky, closed-cell foam tape
. strangely, it also sounds like feedback whenever anything solid
gets too near the mic
(eg, you can wear a hat but you can put your fingers on the mic without
getting a high-pitched whine)
. also tried bringing the speaker end up over the knob that anchors the
headband
but it cramps the ear .

7.5.24: parabolic ears
. make a set of parabolic ears to vastly improve hearing .
7.5.25:
. parabolic dishes are the key to long-distance recording since they
concentrate the sound;
and, that same technology can be created at home, and used powerlessly,
if you don't mind looking like mickey mouse .

crime
map shows suburban crime is happening mostly city-center and
north-east
quadrants;
. the hotspots for urban crimes are downtown, and near the courthouse
weapons
7.5.14: taser`basics
. the way tasers work without melting itself,
is that the voltage is very high and the amperage is very low,
so that even a thin wire carry a large punch
. the one that claim to not kill the target likely do so by
not directing the current across vital organs
. it needs some type of capacitor that unloads a small amount of power
at a very high voltage .
. what a farad is?
. carrying one coulomb of charge -- a volume of current --
when one volt is applied .
7.2.25:
taser risks
Tactical And Crowd Control->Less Lethal->Taser
. not only do some deaths occur from being shocked,
but the needles don`t always penetrate clothes covering the center of
mass
and today I noticed this goofiness:
instead of try&buy, the following company is offering only
buy&be tried!
"( Activation/Registration required for unit to operate
. Age and
background check will be performed at activation. )
--. a better idea is a combination of pepper bullets and hand-combat
stun guns for the drug-soaked who don't respond to pepper .
