Automatic Armor Sensor Aids Police
Law enforcement and military personnel will no longer be left alone in the field while under attack, with rescue squads
scrambling to locate them.
Ken Brinkley, the senior vice president
of Select Engineering Services and a
former military veteran and police officer,
has invented the AID: Automatic Injury
Detection sensor that can be placed in body
armor and will automatically alert up to 30
preset cell phone numbers when the armor is
pierced by either a bullet or a knife.
Brinkley said one of the major issues for
police and military under times of attack is
He said often messages from officers in the
field do not come in clearly and if they are
under attack, the message may either become
quickly outdated or will tip off the attackers
to the officer’s location.
However, with AID, the sensor will
automatically send out a signal to dispatch,
alerting the headquarters of the situation
and eliminating the need for human
“What the beautiful thing about this is, if
you get shot or stabbed, it sends out a signal
in seconds,” Brinkley said in an exclusive
interview with R&D Magazine. “So you
know exactly where they are at and everyone
knows at the same time.
The device also has no tracking capabilities
unless it is pierced by a 9 millimeter or
.22-caliber projective or blade instrument.
When it is pierced, the sensor sends a group
text message with global positioning up to
preset cell phones, and at the same time
the sensor sends the message to the cell
phone, it will also send a message to radio
Brinkley said one of the issues during
times when officers or military personnel are
being attacked is that after they call in their
location, they often are forced to move to
different locations, meaning the previous call
“If you are running, you are not in the same
place that you were a minute ago,” he said. “So
the data you got a minute ago is old.”
Brinkley said police radios currently have
a “hot button” that officers can press when
they are under duress. However, Brinkley
said officers frequently accidently hit the
button and dispatchers are often taught to
“The problem is it is pushed all the time,
so they are sort of trained to ignore it,” he
Brinkley explained that when in dangerous
situations involving gunfire, many officers
turn off their radios because they do not
want their assailants hearing the radio and
locating where the officer is located.
“Most officers turn their radio off because
it is more important to not give away your
position in that environment than it is to talk
to your dispatcher,” Brinkley said.
Another problem that is eliminated by
using the sensors is that radio calls often
come in unclear and it is difficult for the
dispatchers to understand the message.
Brinkley said it is often difficult to speak
clearly in times of duress, and the dispatchers
often cannot hear the location being
That was how he came up with the idea
after hearing one of his calls on the radio
played back to him.
“If you asked me before I heard the radio
tape, I would have said I spoke slowly and
clearly because I thought I did,” Brinkley
said. “When you are under duress it just
makes everything that much harder.
