Oh yeah so there's about the sixty
00:00:04
thousand that per year are due to car
00:00:09
accidents about five thousand are
00:00:12
generally family killing their own
00:00:15
children on parking lots. And all these
00:00:17
this can be avoided by achieving better
00:00:21
faster sensing of the treaty
00:00:24
environment around us. And if you do
00:00:26
that you can also do a few more things
00:00:28
you could make the buildings more
00:00:30
intelligent put the light and the
00:00:32
heating when it's necessary you can
00:00:34
make autonomous view high "'cause" that
00:00:36
can be in in inner cities without
00:00:40
pollution and then you can do a number
00:00:41
of advances in robotics that's what we
00:00:44
do we do fast really sensor so very be
00:00:47
a system integration project which we
00:00:50
started about two years ago with a
00:00:51
little team essentially what we do is
00:00:54
very simple we measure the speed of
00:00:56
light okay so if we measure the speed
00:00:58
of light do we know the constants we
00:00:59
know the distance okay so we send a
00:01:02
flash of lights with your camera and we
00:01:04
get it back and each time we send the
00:01:07
photon we measure what was or speed for
00:01:10
example with the wanted because seconds
00:01:12
I can master three centimetres. But off
00:01:15
and that's not enough you want to be
00:01:16
down to the meeting meter. And you also
00:01:19
want to do it over an are seen like if
00:01:21
you were taking the picture. So that's
00:01:23
what we do again we create a sensor
00:01:26
that sees that and it sees object the
00:01:29
fickle and challenging like a
00:01:31
pedestrians where you have the yellow
00:01:33
dots and you know bus and at high speed
00:01:36
hundred keep them in an hour and with
00:01:38
bad lighting or too much sun or do we
00:01:41
need some classes so that's the
00:01:42
challenge how you build it is very
00:01:44
simple you sample a couple a set of
00:01:48
components okay they're described here
00:01:52
we ten years of recharge enabled us to
00:01:55
do large scale our race of single photo
00:01:57
detectors I'll tell you what is a
00:01:59
single for the detector but is a very
00:02:01
efficient we use the latest lasers and
00:02:04
we build everything into a computer or
00:02:06
one centimetres that provides on your
00:02:09
real time one thousand frame per second
00:02:11
and the lies as of the date on the
00:02:14
single photo avalanche was about ten
00:02:16
years of research here at EPF and it's
00:02:19
interesting because yes a single photon
00:02:22
can generated a pulse of current it's
00:02:26
well known zoom thirty years. Well why
00:02:28
we're interested in that is because if
00:02:30
it's a single photon. It's the most
00:02:32
energy efficient in lighting. So we can
00:02:35
go in low lighting but it's also the
00:02:37
fastest because only need the the text
00:02:38
one so we can operate to one million
00:02:40
frame per second a camera that's way
00:02:42
faster than anything you know today and
00:02:46
the challenge was to build them in our
00:02:48
is like that so if I have many points I
00:02:50
can do the very many many measurements
00:02:52
and I told you and that we're able to
00:02:54
do it. Now yeah people are really
00:02:56
really interest and that's because the
00:02:58
other people would be dissolved almost
00:02:59
cards that you saw on TV they usually
00:03:02
use the radar in one dimension and then
00:03:04
they added a camera like out wise in
00:03:05
two dimensions but this is not perfect.
00:03:08
So they have to add a light are but the
00:03:10
light I on the balloon carcass hundred
00:03:13
and eighty thousand dollar we try to
00:03:15
make it four hundred and eighty dollars
00:03:17
one thousand time and not only that you
00:03:20
need to do less processing because we
00:03:22
do the calculation on board in the
00:03:23
single chip. It's way better than image
00:03:26
processing which doesn't work at night
00:03:28
and requires multiple frames. So it's
00:03:30
slow and it's way better no one ever
00:03:32
that was done in in sensing it's really
00:03:35
useful you'd use a light are to combine
00:03:37
with the radar and a camera and you
00:03:39
make these these car better say fifty
00:03:42
thousand nice for your creed the new
00:03:45
generation of the tone was robots and
00:03:46
we do it by assembling these three
00:03:48
components making cost the price of so
00:03:51
the team is young. But the professor
00:03:53
was behind the sensor of the Microsoft
00:03:56
enact the RCTO which is an EPFL
00:03:58
graduate created similar sensors at a
00:04:01
sports for tonics okay so we've shipped
00:04:03
some of these products more than a
00:04:05
hundred million units in the world and
00:04:06
now we're addressing the biggest system
00:04:08
integration challenge I have are faced
00:04:10
in my carrier you know I've for tonics
00:04:12
I've semiconductor I've optics and I'm
00:04:15
looking for people we'll have a three
00:04:18
three or four harbouring slots mostly a
00:04:20
chip designers at this stage but then
00:04:23
and battered a system programmer
00:04:24
software developers and maybe people
00:04:28
designing complex optics and so lot of
