Abstract

A sensor includes a housing and a mass, suspended in the housing. The motion of the mass emulates dynamic behavior of a brain of the wearer along a plurality of axes. At least one sensing element is coupled to generate sensor data based on the motion of the mass, in response to an impact to a protective helmet.

Claims (27)

1. A sensor for monitoring protective headgear of a wearer, the sensor comprising:

a housing;

a mass, suspended in the housing along a plurality of axes via at least one spring element that includes a six-point suspension harness, wherein motion of the mass emulates dynamic behavior of a brain of the wearer along the plurality of axes;

at least one sensing element, coupled to generate sensor data based on the motion of the mass, in response to an impact to the protective headgear; and

at least one damping element, coupled to the mass, for damping the motion of the mass along the plurality of axes.

2. The sensor of claim 1 wherein the at least one spring element further includes at least one of: an elastic band, a coil spring, a leaf spring, an elastomeric solid, a colloid, a suspension and a gel.

3. The sensor of claim 1 wherein the damping element includes at least one of:

a fluid, a colloid, a gel, and a suspension.

4. The sensor of claim 1 wherein the at least one sensing element includes a contact sensor that generates sensor data in response to displacement of the mass along the at least one axis.

5. The sensor of claim 1 wherein the at least one sensing element includes a plurality of sensing elements that generate the sensor data to indicate motion data along the plurality of axes.

6. The sensor of claim 1 wherein the motion of the mass is constrained via at least one constraining element that resists the motion of the mass until an impact threshold is exceeded.

7. The sensor of claim 1 wherein the at least one sensing element includes a strain gauge that generates sensor data in response to a strain induced by the mass along the at least one axis.

8. An article of protective headgear comprising, a headgear element for use by a wearer;

at least one sensor coupled to the headgear element, wherein the at least one sensor includes:

a housing;

a mass, suspended in the housing along a plurality of axes via at least one spring element that includes a six-point suspension harness, wherein motion of the mass emulates dynamic behavior of a brain of the wearer along the plurality of axes;

at least one sensing element, coupled to generate sensor data based on the motion of the mass, in response to an impact to the protective headgear; and

at least o ne damping element coupled to the mass, for damping the motion of the mass along the plurality of axes.

9. The article of protective headgear of claim 8 wherein the at least one spring element includes at least one of: an elastic band, a coil spring, an elastomeric solid, a gel, a colloid, a suspension and a six-point suspension harness.

10. The article of protective headgear of claim 8 wherein the damping element includes at least one of: a fluid, a gel, a colloid and a suspension.

11. The article of protective headgear of claim 8 wherein the at least one sensing element includes a contact sensor that generates sensor data in response to displacement of the mass along the at least one axis.

12. The article of protective headgear of claim 8 wherein the at least one sensing element includes a plurality of sensing elements that generate the sensor data to indicate motion data along the plurality of axes.

13. The article of protective headgear of claim 8 wherein the motion of the mass is constrained via at least one constraining element that resists the motion of the mass until an impact threshold is exceeded.

14. The article of protective headgear of claim 8 further comprising;

a radio frequency (RF) transmitted that transmits the sensor data in response to the impact event.

15. The article of protective headgear of claim 8 further comprising;

a device interface for coupling to a monitoring device and for sending the sensor data to the monitoring device, when the monitoring device is coupled to the device interface.
