Abstract

A threat analyzer receives threat data measured by detectors. The threat data characterizes a status of detected emissions for a corresponding detector. The threat analyzer analyzes the threat data to identify a geographic region that contains a threat to humans and stores the threat data and analyzed data in a database. The machine readable instructions also include a graphical user interface (GUI) generator that provides an interactive map with indicia that characterizes the analyzed threat data.

First claim

What is claimed is:

1. A system for monitoring operations of a computing platform comprising:
a non-transitory memory for storing machine readable instructions; and
a processing unit that accesses the memory and executes the machine readable instructions, the machine readable instructions comprising:
a threat analyzer that:
periodically and/or asynchronously receives threat data from the mobile computing devices, the threat data measured by wearable detectors communicating with mobile computing devices, wherein the threat data includes a measurement of detected emissions and a timestamp for the measurement, for a corresponding wearable detector;
monitors the measurement of the detected emissions included in the threat data to determine a threat;
analyzes the threat data to identify a geographic region that contains the threat to humans and determines a signature of the threat based on the threat data;
stores the signature of the threat, the threat data, and analyzed data in a database; and
identifies a source of the threat by identifying historical threats from the database that have a same signature as the threat based on a forensics analysis and triangulates a location of the threat based on the threat data measured by three or more of the wearable detectors and location data provided by the mobile computing devices; and
a graphical user interface (GUI) generator that provides an interactive map with indicia includes icons, each representing the location and a status of the three or more wearable detectors in the geographic region that provided the threat data, that characterizes the analyzed threat data;
wherein in response to detecting the threat, the threat analyzer further:
identifies a subset of the wearable detectors proximate to the threat; and
increases a measurement sensitivity level for the subset of the wearable detectors from a first level to a second level.

2. The system of claim 1 , wherein the threat corresponds to a radio frequency (RF) emitter that provides a pulsed RF signal at a selected frequency.

3. The system of claim 2 , wherein the selected frequency is between about 150 megahertz (MHz) and about 1.5 gigahertz (GHz).

4. The system of claim 2 , wherein determining the signature of the threat includes identifying a pulse width and the selected frequency of the threat.

5. The system of claim 1 , wherein the threat corresponds to a radioactive source or toxic chemical emitter.

6. The system of claim 1 , wherein the interactive map is provided as a webpage.

7. The system of claim 1 , wherein the wearable detectors are distributed in multiple continents of earth.

8. A non-transitory machine readable medium having machine executable instructions executable by a processing unit, the machine executable instructions comprising:
a threat analyzer that:
periodically and/or asynchronously receives threat data from the mobile computing devices, the threat data measured by stationary detectors and wearable detectors communicating with mobile computing devices, wherein the threat data includes a measurement of detected emissions and a timestamp for the measurement, for a corresponding stationary detector or a corresponding wearable detector;
monitors the measurement of the detected emissions included in the threat data to determine a threat;
analyzes the threat data to identify a geographic region that contains the threat to humans and determines a signature of the threat based on the threat data;
stores the signature of the threat, the threat data, and analyzed data in a database; and
identifies a source of the threat by identifying historical threats from the database that have a same signature as the threat based on a forensics analysis and triangulates a location of the threat based on the threat data measured by three or more of the wearable detectors and location data provided by the mobile computing devices; and
a graphical user interface (GUI) generator that provides an interactive map with indicia includes icons, each representing a location and a status of the three or more wearable detectors and/or the stationary detectors in the geographic area that provided the threat data, that characterizes the analyzed threat data;
wherein in response to detecting the threat, the threat analyzer further:
identifies a subset of the stationary detectors and/or the wearable detectors proximate to the threat; and
increases a measurement sensitivity level for the subset of the stationary detectors and/or the wearable detectors from a first level to a second level.

9. The medium of claim 8 , wherein the threat corresponds to a source of radio frequency (RF) emissions that provides a pulsed RF signal at a selected frequency.

10. The medium of claim 9 , wherein the determining the signature of the threat includes identifying a pulse width and the selected frequency of the threat.

11. A method comprising:
periodically and/or asynchronously receiving, at a computing platform, threat data measured by stationary detectors and mobile detectors communicating with mobile computing devices, wherein the threat data includes a measurement of detected emissions and a timestamp for the measurement, for a corresponding stationary detector or a corresponding mobile detector;
monitoring, by the computing platform, the measurement of the detected emissions included in the threat data to determine a threat;
analyzing, by the computing platform, the threat data to identify a geographic region that contains the threat to humans and to determine a signature of the threat;
storing, by the computing platform, the signature of the threat, the threat data, and analyzed data in a database;
identifying, by the computing platform, a source of the threat by identifying historical threats from the database that have a same signature as the threat based on a forensics analysis and triangulates a location of the threat based on the threat data measured by three or more of the wearable detectors and location data provided by the mobile computing devices; and
outputting, by the computing platform, a dashboard that provides an interactive map with indicia includes icons, each representing a location and a status of the three or more mobile detectors or the stationary detector in the geographic area that provided the threat data, that characterizes the analyzed threat data,
wherein in response to detecting the threat, the computing platform further:
identifies a subset of the stationary detectors and the mobile detectors proximate to the threat; and
increases a measurement sensitivity level for the subset of the stationary detectors and the mobile detectors from a first level to a second level.

12. The method of claim 11 , wherein the threat is a pulsed radio frequency (RF) signal at a selected frequency.
