and function differs from the claimed invention. We agree
with appellants.
Caiati discloses (column 6, lines 13-17 and 55-61) that:
[w]hen the contents of the shift register 48 have
been read into the memory system 52, . . . the
memory address counter and decoder 51 supplies a
shutdown enable signal SDE to the power supply 32
which is disabled thereby to prevent any further
information from being monitored by the solid state
crash recorder.
. . . .
. . . When the shutdown enable signal SDE is
generated, the SCR 66 is gated on to short the
battery to ground through the fuse 58. The current
through the fuse 58 is sufficient to cause it to
open the circuit from the DC voltage source 54.
Consequently, the solid state crash recorder is
thereafter disabled.
In other words, the grounding element is not directly
connected to a crash sensor nor does it act in response to a
direct signal from a crash sensor, as recited in the claims.
Instead, the grounding element receives an enable signal from
memory and address counter and decoder 51, and the signal is
received only after the contents of the shift register 48 have
been read into memory. Accordingly, Caiati's structure and
