Abstract: An impact sensor for characterizing impact at a headpiece comprises: a flexible base; an acceleration sensor provided on the flexible base and configured to generate impact data; a control unit provided on the flexible base and configured to receive the impact data from the acceleration sensor; a power source provided on the flexible base and in communication with the acceleration sensor and the microcontroller; a communication module provided on the flexible base and configured to send impact data for processing; and a housing enclosing the flexible base, the acceleration sensor, the microcontroller and the power source, the housing shaped and constructed for mounting an interior surface of the headpiece such that it is flush with internal geometry of the headpiece.

Abstract: 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.

Abstract: Impact at a headpiece, for example a protective helmet, is characterized in part using an impact sensor including at least one acceleration switch positioned on the helmet. A microcontroller is configured to identify and store acceleration switch opening duration data based on the binary output values of the at least one acceleration switch. A processor at a portable electronic device receives the acceleration switch opening duration data and determines whether the experienced impact force is associated with an impact force magnitude that is within a predetermined head injury range of magnitude. An impact alert is generated when the impact force magnitude is within the predetermined head injury range of magnitude. In an embodiment, the portable electronic device displays a severity indication and an identifier of a person associated with the sensor that experienced impact.

Abstract: A method of calibrating a data recording unit for measuring head acceleration, including the steps of providing a data recording unit mounted to a head protector, mounting the head protector on a support, subjecting the head protector and support to a force or pressure, measuring acceleration of the head protector resulting from the force or pressure, measuring acceleration of the support resulting from the force or pressure, and determining a relationship between the measured acceleration of the head protector and of the support.

Abstract: An apparatus for recording data indicative of acceleration of a part of a person's body or other object, including first memory means for receiving acceleration data from an acceleration sensor, second memory means operatively coupled to the first memory means for receiving data from the first memory means, and a data transfer controller for controlling the transfer of data from the first memory means to the second memory means based on the acceleration data.

Abstract: A headpiece assembly for use with a night vision mounting arm includes a bump shell and an interior suspension assembly for seating on the head of a human. A mounting bracket is secured to the front of the bump shell for removably attaching the night vision mounting arm to the bump shell. A ballistic shell has a bottom forming an opening and a coupling mechanism for removably securing the ballistic shell to the bump shell when the ballistic shell is placed over the bump shell. The ballistic shell has a front and a notch extending upwardly from the opening into the front for receiving the mounting bracket when the ballistic shell is placed over the bump shell so as to permit the night vision mounting arm to be attached to the bump shell during use of the ballistic shell.
