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.
Claims15
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.
