Imagine, don't feel you need to be distracted by that
staircase coming up, or that person coming out of the
elevator after you've been waiting on it thinking it'd be
empty, or that sidewalk you're about to walk off of
into traffic because you are drifting off course. You can
your own business like a boss with the new
SmartPhone Awareness System (SPAS).
This phone application utilizes radar to sense oncoming
objects, objects that have slowed down and now become
an obstacle, detect drifting and swaying out of a straight

BONUS!! There is an inebriated mode for our overserved
pedestrians who need a bit of help getting there swerve

||The whole point of smartphones is to help weed out the less fit.
||As of today, there is no unclassified self-contained radar
system that can fit in the palm of the hand, much less be
crammed into a hand-held device containing a bunch of
other crap. If there was, it would chew up your battery
charge in just few minutes. Also, the conflicting signals
play merry hell with reception, as (I think, I don't have the
books right in front of me) the frequencies required to
generate an ultra-close return of any accuracy are pretty
close to those used in cellular communication. Finally,
local and state law-enforcement agencies, the NTSB, and
the military generally frown upon the unregulated use of
||Having it kill their battery in a few minutes would give them a sonar capability as they start screaming...
||Ever heard of Micropower Impulse Radar?
||I think that can fit into the palm of you hand. It probably needs some refinement to get it into a cell phone.
||It's probably not capable enough to provide all the functionality in this idea, but it might be able to warn you before you bump into a wall.
||Actually I'd say that this app is very Darwinian. Something like this will never be 100% reliable. Currently, people who are sucked into their phones often try to give a little attention to the outside world. With this app they would give up all efforts to keep track of what's happening. When the app failed, they would meet an (un)timely end.
||// Ever heard of Micropower Impulse Radar? //
||Yes, I have. It's one of the last things my grandfather was
involved with before his death in 1996. Before posting my
previous anno, I searched around the 'net; the only self-
contained MIR devices comparable in size to a cellphone
available to the civilian sector that I could find are
studfinders with a maximum range of a few inches. All of
the devices of such size but capable of registering accurate
returns at greater ranges rely on external power sources. If
I missed something, please correct me.
||You did, and we could, but then we'd have to kill you.
||Not that that's a problem, you understand ...
||Re: unclassified; civilian sector. I know about that wall-
penetrating sentry-sensor you limeys have hidden up your
sleeves. I have a Jane's subscription too, you know (or at
least I will until they find out my Grandad's been dead for
||We'd have gotten away with it too, if it weren't for you pesky kids ...
||Common halfbakers, what about ultrasonic backup sensors on cars? Those have at least a five foot range. What about the actual radar sensors used on cars with adaptive cruise control? They wouldn't fit in a normal cell phone but could be worn on the chest, and send warnings through the phone via Bluetooth. As a bonus you would look like Iron Man.

||That _is_ a bonus. Iron Man is the balls.
||The MIR device that [8th] was cryptically muttering about
is a secret piece of tech currently being field-tested by
British special forces units in Afghanistan (most likely the
SAS). It's a remote sentry alarm that that uses MIR to
detect movement. These are everyone's (i.e. Jane's
Mossad, and [The Alterother]) best guesses on the specs: a
little larger than a
deck of cards, has a range of 7 - 9 meters, can somehow
tell the difference between a human and an animal of
equivalent size (maybe by metal detection, maybe more
sophisticated), has a battery life of 10-15 hours, and is
stenciled with that new UK camo pattern I can't remember
the name of. It broadcasts a silent alarm on some hard-to-
find frequency to a receiver/remote control, which has a
reception range of up to 1 km.
