Appeal No. 2001-1340
Application 08/944,885
features of the claimed invention. Specifically, although the examiner has pointed to a
circuit in Hogan for performing various functions including comparison and a display
capable of providing a readout value in any desirable form [answer, page 5], the circuit
of Hogan does not perform the specific function recited in the claimed invention nor
does the display in Hogan display the specific value recited in the claimed invention.
Each of the claims on appeal recites a step or device for determining if the
impact signal exceeds a threshold value and, if it does, a step or device for measuring
the length of time that the impact signal exceeded that threshold value. Although
Hogan does determine if a threshold value has been exceeded, Hogan does not
measure the duration of time in which the threshold is exceeded. Hogan simply
measures the signal for a predetermined time in which it is known that the signal will
have fallen below the threshold so that all critical data will be stored. Thus, Hogan does
not perform the specific claimed step of measuring the length of time that the impact
signal is above the threshold value. Since Hogan does not determine this elapsed time
value, Hogan also does not display this value.
