Appeal No. 1999-0419
Application 08/383,483
Bellman adds to the video camera transmitter teachings already in Hurwitz and
Nakajima. In addition to using microwave frequencies as Bellman itself teaches, he
also indicates that it was known in the art to use normal radio frequencies for such
purposes as expressed in the first column of the background of the invention discussion
therein. It is also noted that the discussion at column 3, lines 18-21 indicates that other
radio frequencies may be employed other than the microwave frequencies used.
Compare Hurwitz and Nakajima as well.
The discussion at column 1 of Bellman indicates that it was considered
advantageous to utilize radio frequency transmissions of video signals to avoid the
limitations of cable connections between the video sensing image devices and their
recording devices. The low-power transmitting capability of claim 13 is a relative term.
A relative low power utilized in Bellman is in the context of not only the broadcast
distance but the nature of the modulation scheme at microwave frequencies. Such are
governed by Federal Communications Commission (FCC) regulations for whatever
environment they are to be used in. Because the combination of Kozuki and Citizen
utilizes the ability to receive video signals from normal broadcast television stations of
relatively high power, to utilize a remote video broadcast device in accordance with
Bellman’s teachings, the power requirements would have been significantly lower as
required by FCC regulations. Moreover, the selectability between the plural cameras
recited in the combination of claims 2 and 13 would have been obviously optimally done
by the normal channel selector provided for broadcast TV channels as taught by
