Abstract

A sensor system is provided for monitoring anti-personnel effectiveness of a gun that fires a projectile against a mannequin target. The system includes an instrumentation sensor, an aggregation controller and a base station. The instrumentation sensor is disposed on the target. The sensor transmits a status condition based on electrical integrity. The status condition is either intact as default or else disablement in response to impact from the projectile. The aggregation controller receives the status condition from the sensor and transmits the status information as aggregated information. The base station receives the aggregated information for analysis to determine the effectiveness in response to the gun firing at the target.

First claim

What is claimed is:

1. A sensor system for monitoring anti-personnel effectiveness of a gun that fires a projectile against a mannequin target, said system comprising:
an instrumentation sensor for disposition at an anatomical position on the target, said sensor transmitting a status condition based on electrical integrity, said status condition being one of intact as default and disablement in response to impact from the projectile, said default indicating electrical connection and said disablement indicating electrical disconnection;
an aggregation controller for receiving said status condition from said instrumentation sensor and transmitting said status condition and said anatomical position as aggregated information; and
a base station for receiving said aggregated information for analysis to determine the effectiveness in response to the gun firing at the target, wherein
said instrumentation sensor includes:
a frangible substrate that fractures upon said impact, thereby altering said status condition from said intact to said disablement,
a transmitter for sending said status condition to said aggregation controller,
an electrical circuit disposed on said substrate that passes current therethrough absent said impact, and interrupts said current in response to disintegration of said substrate from said impact, and
a microprocessor for providing control for said transmitter and said current to said circuit,

the target includes a plurality of instrumentation sensors, each instrumentation sensor being disposed at an anatomically analogous location in relation to a disablement status that indicates the effectiveness on the target, and
said disablement status includes one of healthy, wounded and incapacitated such that healthy indicates impact absence, wounded indicates a non-lethal projectile impact at a non-vital sensor-location on the target, and incapacitated indicates a mortal projectile impact at a vital sensor location on the target.

2. The system according to claim 1 , wherein said substrate is one of a ceramic tile, a paper sheet, a plastic panel, an epoxy plate, and said circuit is a wire trace disposed on a planar surface of said substrate.

3. The system according to claim 1 , wherein said impact triggers an event indicator associated with a timestamp provided by a global positioning system satellite receiver.

4. The system according to claim 1 , wherein said aggregation controller includes:
a process controller for aggregating said status condition, and
a relay transceiver for receiving said status condition from said instrumentation sensor and sending said aggregated information to said base station.

5. The system according to claim 1 , wherein said base station includes:
a graphical user interface (GUI) for converting said aggregated information into visual representation of the effectiveness on the target.

6. The system according to claim 1 , wherein said each instrumentation sensor further includes:
an impact detector for indicating said status condition;
a second microprocessor for determining said status condition from said detector; and
a bus for providing said status condition from said second microprocessor to said aggregation controller.

7. The system according to claim 6 , wherein said bus is one of a conduction connection and a wireless transmitter.

8. An instrumentation sensor for disposition on a mannequin target in association with a detection system for monitoring antipersonnel effectiveness of a gun that fires a projectile against said target, said instrumentation sensor comprising:
a transmitter for transmitting a status condition to the detection system based on electrical integrity, said status condition being one of intact as default and disablement in response to impact from the projectile, said default indicating electrical connection and said disablement indicating electrical disconnection;
a frangible substrate that fractures upon said impact, thereby altering said status condition from said intact to said disablement;
an electrical circuit disposed on said substrate that passes current therethrough in absence of said impact, and interrupts said current in response to disintegration of said substrate; and
a processor for providing control for said transmitter and said current to said circuit;
wherein the instrumentation sensor is part of a sensor system, and the sensor system comprising:
an aggregation controller for receiving said status condition from said instrumentation sensor and transmitting said status condition and an anatomical position as aggregated information; and
a base station for receiving said aggregated information for analysis to determine the effectiveness in response to the gun firing at the target,
the target includes a plurality of instrumentation sensors, each instrumentation sensor being disposed at an anatomically analogous location in relation to a disablement status that indicates the effectiveness on the target, and such that healthy indicates impact absence, wounded indicates a non-lethal projectile impact at a non-vital sensor-location on the target, and incapacitated indicates a mortal projectile impact at a vital sensor location on the target.

9. The instrumentation sensor according to claim 8 , wherein said substrate is one of a ceramic tile, a paper sheet, a plastic panel, an epoxy plate, and said circuit is a wire trace disposed on a planar surface of said substrate.

10. The instrumentation sensor according to claim 8 , wherein said impact triggers an event indicator associated with a timestamp.

11. A sensor system for monitoring anti-personnel effectiveness of a gun that fires a projectile against a mannequin target, said system comprising:
a plurality of instrumentation sensors for disposition on the target, said disposition of each instrumentation sensor of the plurality of instrumentation sensors being at an anatomically analogous location in relation to a disablement status that indicates the effectiveness on the target in response to impact from the projectile;
an aggregation controller for receiving a status condition from said each instrumentation sensor of said plurality of instrumentation sensors and transmitting corresponding said status condition and said anatomically analogous location from said each instrumentation sensor as aggregated information; and
a base station for receiving said aggregated information for analysis to determine the effectiveness in response to the gun firing at the target, wherein
said disposition on the target corresponds to the anatomically analogous location in relation to the disablement status that indicates the effectiveness on the target, and
said disablement status includes one of healthy, wounded and incapacitated, such that the healthy indicates impact absence, the wounded indicates a non-lethal projectile impact at a non-vital sensor-location on the target, and the incapacitated indicates a mortal projectile impact at a vital sensor location on the target, wherein said each instrumentation sensor includes:
a transmitter for transmitting the status condition to said aggregation controller based on electrical integrity, said status condition being one of intact as default and disablement in response to impact from the projectile;
a frangible substrate that fractures upon said impact, thereby altering said status condition from said intact to said disablement;
an electrical circuit disposed on said substrate that passes current therethrough in absence of said impact, and interrupts said current in response to disintegration of said substrate; and
a processor for providing control for said transmitter and said current, to said circuit.
