NASA Destination Tomorrow Segment describing NASA's Child Safety Alert System for automobiles.
According to a national non-profit safety organization called Kids in Cars, 81 infants
00:00:00
and small children died last year while being left unattended in and around a vehicle, up
00:00:13
nearly 100% from the previous year.
00:00:18
In many cases, parents simply forget they've left their children unattended, while others
00:00:24
leave their children in the car for a few minutes to run errands.
00:00:28
Unfortunately, leaving a child in a car for even a short time can end tragically, because
00:00:32
temperatures inside a car can soar or plummet in just a matter of minutes.
00:00:37
In an effort to combat this deadly problem, NASA has developed a safety device called
00:00:42
a Child Presence Sensor.
00:00:47
This sensor alerts parents who inadvertently leave their children strapped in car seats.
00:00:49
I spoke with Chris Edwards of NASA Langley's Laser Systems Branch to find out more about
00:00:54
this fascinating innovation.
00:00:59
Well, the inspiration for the Child Safety Sensor came from an incident that happened
00:01:01
that I read about, where a child had died from being left in a vehicle.
00:01:05
I really wanted to develop a technology that would prevent this from happening, sort of
00:01:09
a second set of eyes and ears.
00:01:13
And I looked at technology that was out there and realized there really wasn't any.
00:01:15
There's nothing a consumer could purchase to prevent that from happening.
00:01:19
I looked at how the incident occurred and then realized that that could really happen
00:01:22
to anybody.
00:01:26
Being that a change in routine, something like that, it's usually a series of events
00:01:27
that happen.
00:01:31
I really wanted to break that chain of events.
00:01:32
So we decided to go ahead and form a team, Terry Mack of Lockheed Martin, Ed Malin of
00:01:35
Langley, and develop the technology and make it affordable and easy to use for the average
00:01:40
person to be able to just install it in any car seat, in any vehicle, and give them and
00:01:46
that child a second chance.
00:01:51
This is how the Child Present Sensor works.
00:01:53
A thin sensor is placed between the cushion and the frame of the baby seat.
00:01:55
The sensor, or switch, has a large activation area with a sensitivity of about 8 ounces.
00:02:00
Attached to the switch is a transmitter that mounts on the baby seat.
00:02:06
The sensor switch triggers immediately when a child is placed in the seat and deactivates
00:02:10
when the child is removed.
00:02:15
The sensor will detect weight once the child is placed in the seat and transmits a unique
00:02:17
code to a keychain alarm module with a corresponding radio frequency.
00:02:22
If the driver moves too far away from the vehicle, a small alarm built into the keychain
00:02:27
sounds 10 warning beeps.
00:02:32
If the driver doesn't return within one minute, the alarm will beep continuously and cannot
00:02:34
be turned off until it is reset on the transmitter.
00:02:38
How did NASA contribute to the development of this child safety device?
00:02:42
At NASA we have a 757 aircraft as a flying laboratory that we use for aviation safety.
00:02:45
And they have an experiment on there that takes data that dealt with the stresses on
00:02:51
the landing gear and transmitting that data back into the aircraft with a radio frequency
00:02:54
link.
00:02:58
And we took a similar approach with the Child Safety Sensor in that we monitor if the child
00:03:00
is in the seat and we send that data to the receiver which is on the keychain that a driver
00:03:04
would hold.
00:03:09
So we were able to use that technology and it inspired us to develop the Child Safety Sensor.
00:03:10
So what are your hopes for the future of this invention?
00:03:16
The main goal is to save lives.
00:03:18
We're currently seeking commercial partners to license the technology.
00:03:21
We've designed it to be inexpensive, the cost depends on how many units are produced, but
00:03:25
certainly in the $20 to $30 range is reasonable.
00:03:29
And that's what we're currently shooting for.
00:03:33
So if we can get a commercial partner, a lot of the technology, most all of it's been developed
00:03:34
so it should go to market fairly quickly.
00:03:39
When I started this I really wanted anybody at a department store or whatever to come
00:03:41
and be able to pull this off the shelf, put batteries in it, place it in their car and
00:03:46
provide that second chance.
