Abstract

Detecting the current state and status of a police officer. The invention can detect when an officer is in a foot pursuit, in an altercation with another person, is in proximity to gunshots, and when an officer is incapacitated. The invention is used to monitor the operational status of a police officer. The invention includes a hand held device which has a three axis accelerometer, three axis gyroscope, microphone, one or more microprocessors, cellular radio, and a camera. Measurements relating to physical movements of the officer are made by interpreting the outputs from the accelerometer, gyroscope, and the microphone. These outputs are constantly analyzed for patterns and when a threat pattern is recognized, the device will communicate the officer'"'"'s status, state and position to a central authority.

Claims

1. A method for creating acoustic fingerprints for gunshot sounds, the method comprising:

receiving sounds in a first high sample rate digital audio receiver,

running a software module in a processor, that analyzes sound samples within said sounds to produce an acoustic fingerprint of said sound samples,

first placing said first high sample rate digital audio receiver in a simulated environment, which simulates an environment in which a firearm shot is likely to be detected,

recording sounds using said first high sample rate digital audio receiver, including a plurality of shots of a

firearm will be shot a plurality of times, in a plurality of directions relative to said first high sample rate digital audio receiver,

said software module operating to analyze each sound of a gunshot and for each sound of a gunshot creating a acoustic footprint of said sound of a gunshot, and

averaging said fingerprints of said gunshot sounds fired in the plurality of directions to create an averaged fingerprint, and saving the averaged fingerprint in a database along with metadata associated with the fingerprints, said metadata includes at least a firearm manufacturer, model, caliber, ammunition manufacturer, bullet type, bullet weight, bullet type, and environment where said shot took place.

2. A system for a mobile gunshot detector which detects gunshot sounds and provides alerts responsive to detecting said gunshot sounds, said system comprising:

a device with a GPS sensor,

a microphone,

a speaker,

a processor,

a database containing a plurality of fingerprints of gunshot sounds and metadata associated with each of said plurality of fingerprints of gunshot sounds,

a first software program, running on said processor, analyzing sounds received by said microphone and identifying a suspect sound as a gunshot, by comparing said sounds with said fingerprints

a radio communications link that sends data to a remote location based on said identifying,

said first software program monitors sounds captured by said microphone and captures and digitizes sounds that have a fast rise time and a fast decay time which constitutes a possible gunshot sound,

said first software program analyzes said possible gunshot sound and creates an acoustic fingerprint of said possible gunshot sound, and

said first software program performs a comparison of said acoustic fingerprint of said possible gunshot sound against said database of acoustic gunshot sounds, and

said first software program operating if a match is made between said acoustic fingerprint of said possible gunshot sound and one of the acoustic fingerprints contained in said database, said first software program announcing a warning to a user of said mobile gunshot detector, and

said first software program operating to create a data packet containing a user'"'"'s GPS coordinates, user'"'"'s identification, the fingerprint of the gunshot sound and the metadata for the associated acoustic fingerprint matched in said database, and

said first software program operating send said data packet will be uploaded to said remote location.

3. The system as in claim 2, wherein said remote location is a law enforcement agency dispatcher.

4. A system for a mobile device capable of determining if a police officer is in danger and notifying a law enforcement agency dispatcher if it is determined that the officer is in danger, the mobile device comprising:

a device with GPS sensor,

a microphone,

a speaker,

a three axis accelerometer,

a three axis gyroscope,

a heart rate sensor receiving device,

a wearable heart rate device communicating a user'"'"'s heart rate,

a radio communications link that can send data to a law enforcement agency dispatcher,

a processor, running a first software program which monitors said three axis accelerometer and said three axis gyroscope, and

monitor said heart rate sensor receiving device;

said software program operating when detecting the user starting to move in a direction at an accelerated pace or velocity, and

said user'"'"'s heart rate accelerates,

said software program determining, based on the user'"'"'s velocity and heart rate if the monitored data is symptomatic of the user being in a foot pursuit, and if the determination is that the user is in a foot pursuit, said software program will creating a metadata packet having at least the user'"'"'s identification, time, date, GPS coordinates, and the rate that the user is running, said metadata packet will be uploaded to a law enforcement agency dispatcher;

said software program determining, based on the user'"'"'s velocity, body movement as monitored by said three axis accelerometer and said three axis gyroscope and heart rate if the monitored data is symptomatic of the user being in a physical altercation, and if the determination is that the user is in a physical altercation, said software program will create a metadata packet consisting of at least the user'"'"'s identification, time, date, GPS coordinates, and an indication that the user is in a physical altercation, said metadata packet will be uploaded to a law enforcement agency dispatcher;

said software program will determine, based on the user'"'"'s GPS coordinates and heart rate if the user has not moved and has a heart rate event where the heart rate is substantially higher than normal, substantially lower than normal, or has stopped, and

if any of the heart rate events is detected, said software program will create a metadata packet consisting of at least the user'"'"'s identification, time, date, GPS coordinates, and an indication that the user is in a medical emergency situation, and said metadata packet is uploaded to a law enforcement agency dispatcher.
