Appeal No. 2000-2207
Application No. 08/968,379
a pull-up resistor coupled to the sensing line,
the pull-up resistor driving the sensing line to a high
voltage level if the external termination device is
disconnected from the SCSI bus,
at least one termination resistor coupled to each
of the plurality of bus signal lines of the SCSI bus to
provide a terminating impedance at the external connector of
the SCSI bus, and
a plurality of switches each including a
transistor having a gate coupled to the sensing line, each
of the plurality of switches coupled to one of the plurality
of termination resistors and terminating a separate bus
signal line of the SCSI bus if the sensing line is pulled to
the high voltage level.
The Examiner relies on the following prior art:
Thrower et al. (Thrower) 5,381,034 Jan. 10, 1995
Hiroyuki JP 03-023706 Jan. 31, 1991
(published Japanese Kokai Patent Application)
Claims 23-27, 30, 37-40, 42, and 43 stand finally rejected
under 35 U.S.C. § 103(a) as being unpatentable over Thrower in
view of Hiroyuki.
Rather than reiterate the arguments of Appellants and the
Examiner, reference is made to the Brief (Paper No. 33) and
Answer (Paper No. 34) for the respective details.
OPINION
We have carefully considered the subject matter on appeal,
the rejection advanced by the Examiner and the evidence of
obviousness relied upon by the Examiner as support for the
