Appeal 2007-1362
Application 09/972,107
FINDINGS OF FACT
The following findings of fact (FF) are relevant to the issue involved
in the appeal and are believed to be supported by a preponderance of the
evidence.
1. Collar relates to switching means for use on-board a spacecraft
(col. 1, ll. 6-7).
2. Collar’s switching means can be used in a satellite having a
receiving antenna and a transponder in which the wideband F.D.M. signal is
amplified and filtered, de-multiplexed into respective channel slots,
amplified in the narrow band slots, and filtered in those slots and
multiplexed for passage to the transmitting antenna (col. 2, ll. 45-50).
3. As depicted in Figure 3, Collar provides for a first row of switches
5 (col. 3, l. 63 through col. 4, l. 2), and a second row of switches 6 (col. 4, ll.
6-17) as the input switching network. Similarly, two rows of switches 7 and
8 form the output switching network, which is connected to the input
network through amplifier sets 9 and 10. The switches in row 5 are shown
connected in a single ring, as are the switches in row 8. The switches in row
6 are connected in two rings, as are the switches in row 7.
4. Collar further discloses different arrangements, including
connecting the switches in each of rows 5 and 8 in two rings and connecting
the switches in each of rows 6 and 7 in a single ring (col. 5, ll. 17-21).
5. Vannatta relates to a portable radio phone and shows in Figure 5
switches 121 and 130 which are selectively coupled to each other while
switch 130 is further coupled to speaker 178 and microphone 182 via the
transmitter and receiver circuitry 190 and 166 (col. 5, ll. 22-43).
