1. In a ski binding for releasably securing a ski boot to a ski, a method for minimizing injuries in a lower extremity of a skier, said method comprising:

  • measuring a plurality of mechanical deflections induced in said ski binding from interaction between said skier and said ski;

    developing a plurality of first electrical signals, each of said first signals being determined from a different one of said deflections;

    developing a plurality of second electrical signals determined from a relationship between said first signals, said second signals defining a measurement of forces along first selected ones of longitudinal, lateral, and vertical axes of said ski and moments about second selected ones of said axes, said mechanical deflections occurring in response to said forces and said moments; and

    computing from said second signals an actual angle of deflection based on a preprogrammed relationship between said second signals, said actual angle of deflection being about a location of said lower extremity of the skier, said location being selected to prevent injury thereto, said computing step including comparing said actual angle of deflection with a predetermined critical angle of deflection to initiate a release of said ski binding in the event said actual angle exceeds said critical angle.
