Application 08/141,412
meter transponder being electrically connected
to a secondary winding;
(d) allowing passage of the utility through the
meter to provide the measurement;
(e) determining the electrical manifestations of
the measurement in the meter transponder;
(f) providing a portable interrogator having a
primary winding;
(g) bringing the portable interrogator to a
position in relation to the meter transponder
whereby the secondary winding and the primary
winding are disposed such that a signal in
either would induce the same signal in the other
by inductive coupling;
(h) actuating the portable interrogator and
transmitting an electrical signal having a clock
pulse component, from the portable interrogator
to the meter transponder, by placing the
electrical signal on the primary winding whereby
it is induced in the secondary winding, thereby
activating the meter transponder and causing the
meter transponder to obtain said electrical
manifestations, and modulate said electrical
signals with respect to said clock pulse
component, thereby generating a signal represen-
tative of the electrical manifestations of the
measurement available to the interrogator and
placing the signal on the secondary winding; and
(i) determining from the signal the measurement
of utility represented thereby.
47. A utility data gathering system comprising:
an interrogator comprising;
