wireless receiver, with the switch controlling the receiver so
that pushing the switch toggles the receiver between being
enabled and disabled.
Representative independent claim 6 is reproduced as follows:
6. A radio frequency identification device comprising:
a housing;
a battery supported in the housing and having first and
second terminals of opposite polarity;
transmitter circuitry in the housing configured to provide a
modulated backscatter signal by reflecting or not reflecting a
carrier signal provided by an interrogator to communicate with
the interrogator, to identify the device in response to an
interrogation signal by the interrogator;
receiver circuitry in the housing, coupled to the
transmitter circuitry, and configured to receive the
interrogation signal;
a push-on/push-off switch supported by the housing and
controlling whether the circuitry provides the signal to identify
the device by controlling whether or not the receiver is coupled
to the battery, the switch including a first conductor formed of
printed thick film and having a first end coupled to the first
terminal of the battery and having a second end, a second
conductor formed of printed thick film and having a first end
coupled to the receiver and having a second end spaced apart from
the second end of the first conductor, an insulating ring having
a periphery circumscribing the second end of the first conductor
and the second end of the second conductor, and a diaphragm
having a periphery corresponding to the periphery of the
insulating ring and having a conductive face facing the second
end of the first conductor and the second end of the second
conductor, the conductive face of the diaphragm being biased, by
the insulating ring, away from coupling the first and second
