Abstract: A technique for securely clearing the meter after it has been disabled by a security detection scheme without returning the meter to the factory. During this technique, the meter generates a security lock code which is transmitted to a data center computer. The data center computer compares the security lock code with an internally generated security lock code. If the codes agree, the data center computer then generates a security clear code which is transmitted to the meter. The meter then compares this code with an internally generated security clear code. If these codes agree, then the meter clears the security lock flag thereby enabling the meter. As a result, the customer can subsequently remotely set the meter.

Abstract: A relaxation oscillator is disclosed which includes first and second currents for charging and discharging a capacitor (50) wherein the slew rate of the dynamic voltages developed at the terminals of the capacitor (50) remain substantially constant for each frequency of operation which desensitizes the oscillator to the effects of the inherent stray capacitance, and improves the accuracy of the output frequency. A circuit (74,76,78,80) monitors the dynamic voltage across the capacitor (50) and inverts a control signal at opposite polarities of a particular threshold. A bistable circuit (86,88,90,92,94) provides first and second complementary output signals in response to the control signal from the circuit (74,76,78,80). The first and second complementary output signals drive a pair of switching transistors (52,54) which alternate the direction of current flowing through the capacitor (50) so as to provide smooth voltage transitions at the terminals of the capacitor (50).

Abstract: A noise component is extracted either from FM-detected output (1) or from the so-called signal meter in the intermediate frequency amplifier (15). The noise component is amplified (7) and rectified (8) to provide a d-c signal indicative of the noise level. The rectified noise is then shaped (9)to produce a control signal having a predetermined level and a width. The control signal is supplied to the gate circuit(3) to control the opening and closing of the gate through which the FM detected output passes. The gate is closed during a period when the pulse noise is superimposed on the FM detected output, and is opened during a period when the pulse noise is not superimposed to the FM detected output. In the mean time, the rectified d-c signal is smoothed out (11) to be used as a control signal for controlling the stereo separation (17), the attenuation of high frequency component of the MPX-demodulated audio outputs (18), and the overall signal level of the audio outputs (16).
