Appeal No. 96-3264
Application No. 08/361,163
Oka . . . discloses an appliance having a
wireless remote control device, where the remote
control device is capable of controlling the
appliance (see Fig. 1). The appliance has a source
of power and the remote control device has a
separate source of power (Fig. 1). The Appliance
includes a transmitter (unit 4) which is actuated by
a manually depressed switch (unit 5). The
transmitter 4 emits a signal which is received by
the receiver 3. The receiver inherently includes a
suitable alarm device which generates an alarm in
response to a received signal. The Oka reference
does not have the remote control device including
means for intermittently connecting the power source
to the receiver.
The Livingstone reference discloses on p. 1,
lines 12-23, the use of a receiver which includes
means for intermittently connecting the power source
to the receiver for the purpose of conserving power
so that the power source (battery) which powers the
receiver has an extended life.
Since Oka and Livingstone are both from the same
field of endeavor, the purpose disclosed by
Livingstone regarding the intermittent application
of power to the receiver would have been recognized
in the pertinent art of Oka.
Appellants and the examiner agree that “[i]t would have
been obvious at the time the invention was made to a person
having ordinary skill in the art to intermittently apply power
to the receiver as taught by Livingstone in the device of Oka
for the purpose of conserving power so that the power source
(battery) which powers the receiver has an extended life”
