Apparatus and method for measuring and recording data from violent events
First Claim
1. An apparatus for recording information about a plurality of events resulting in application of force to a body, comprising data recording means for recording said 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 said data recording means, and further comprising means for indicating a chronological order of said plurality of events and a generator for generating said means for indicating, wherein said generator is operatively coupled to receive a timing signal from generating means that generates a timing signal for operation of the data recording means.

Abstract
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.
