1. A pressure threshold crossings accumulator for selectively accumulating relative pressure threshold crossings, comprising:

  • computer means for receiving a first plurality of pressure signals representing a second plurality of pressures, and for selectively assigning a threshold flag value which both corresponds to a first pressure vector direction and indicates that a first pressure vector magnitude exceeds a first threshold, and further for providing a unit count when both a second pressure vector magnitude exceeds a second threshold and a second pressure vector direction opposes said first pressure vector direction, wherein said first pressure vector direction and magnitude represent a first sign and magnitude, respectively, of a first pressure differential from a first pressure to a second pressure of said second plurality of pressures, and wherein said second pressure vector direction and magnitude represent a second sign and magnitude, respectively, of a second pressure differential from a third pressure to a fourth pressure of said second plurality of pressures; and

    accumulator means coupled to said computer means for receiving and accumulating said unit count.
