A blast pressure recording device and method includes at least one first sensor for measuring a parameter indicative of a blast event, at least one comparator in communication with the at least one first sensor for determining whether said parameter indicative of a blast event exceeds a predetermined threshold, at least one second sensor for measuring blast pressure, a power control means providing power to the at least one second sensor only when the predetermined threshold is exceeded, and a controller for receiving and recording blast pressure.

Blast exposure recording device

An apparatus as provided for measuring acceleration of a person's head or other object. The apparatus comprises a sensor for sensing acceleration and a controller for controlling recording of data resulting from the sensed acceleration due to an explosive force. The controller is adapted to determine whether or not to enable recording of the data based on the sensed acceleration. A data receiver is provided to receive the sensed acceleration data from the sensing means, and requires electrical power to enable data to be received thereby. The controller controls electrical power to the receiver so that if the sensed acceleration reaches or exceeds a predetermined value, electrical power to the data receiver is enabled. The recorded acceleration data may be used for injury analysis.

Method and apparatus for measuring data for injury analysis

An apparatus is provided for recording information about an event resulting in application of a force to a body. The apparatus comprises data recording means for recording the information, sensor means for sensing a parameter which enables a predetermined source of force to be distinguished from another, predetermined source of force, and control means responsive to the sensed parameter for controlling the data recording means. The sensor means may comprise a pressure sensor for sensing shockwaves resulting from an explosive force and the resulting signal used to distinguish from other events, such as blunt impacts. The pressure signal may be used to control the storage of acceleration data for injury analysis.

Apparatus and method for measuring and recording data from violent events

An apparatus adapted for mounting on a head protector including sensor means for sensing the presence of a head in the head protector. The sensor means includes first and second spaced apart electrode elements adapted to sense the dielectric of a head and the one or more electrode elements include a fastener for fastening an object to the head protector.

An apparatus for mounting to a head protector including a housing having a plurality of parts each defining a portion of the housing, one or more components to be accommodated in the housing, and one or more apertures in the housing for introducing a compound for securing the one or more components in the housing, a protrusion on the exterior surface of the housing for abutting against the exterior surface of the head protector, and a sensor and a coupling for mechanically coupling the sensor to the protrusion to minimize relative movement between the head protector and the sensor.

An apparatus is provided for recording information about an event resulting in application of a force to a body. The apparatus comprises data recording means for recording the information, sensor means for sensing a parameter which enables a predetermined source of force to be distinguished from another, different source of force, and control means responsive to the sensed parameter for controlling the data recording means. The sensor means may comprise a pressure sensor for sensing shockwaves resulting from an explosive force and the resulting signal used to distinguish from other events, such as blunt impacts. The pressure signal may be used to control the storage of acceleration data for injury analysis.
