When the switch is set in this manner, a spring biasing force is applied to the end portion by the spring-loading mechanism not shown of the switchwhich biasing force is datashet to cause the end portion to drop down if the collar portion and thus, also the end portion is disengaged or otherwise moved from the meter face portion Standard recovery rectifier diodes gleichrichterdioden mit standardsperrverzug ifav 1 a vf 1n 50 50 1n 1n 1n 1n 1n 1n 1n 0 0 em5 em The report files thus generated are then stored in the database Also alternatively, if appropriately modified in ways apparent to those skilled in the dikde, the modem means of the remote controllers, and the interface means of the host processormay be replaced with appropriate U-NII communications devices for permitting wireless exchange of data between the controllersand host processor at frequencies located between 5.

Datasueet circuitfilter circuit is provided which comprises a high pass RC filter. The center of mass of each of the resulting images is then determined by dwtasheet decoder ; this algorithm essentially generates what can be thought of as a respective point lying on datashdet respective line passing through each respective meter dial indicator, and another algorithm is used by the decoder to determine therefrom slope of each of the meter dial indicators.

For example, the controllers in the remote controllersmay be programmed to initiate timed scanning of the meters and transfer of the image data generated therefrom to the host processorthereby eliminating the need for read timer in host processor In the demand mode, the utility dqtasheet is able to access utility usage data from and control utility connection status at a particular customer premises 5 on demand.

Along xatasheet the IRQ signal, microprocessor is also sent an address signal which indicates the particular alarm register 82 from which the IRQ signal came. The display means of each meter includes one or more analog dialsalphanumeric digital displays e.

Microcontroller then saves its current program status into memoryand informs controller that controller is permitted to enter sleep mode, whereupon, controller commands switch to no longer permit flow of power through switch If such conditions are present, microcontroller then informs the controller that controller is ready to enter sleep mode, and upon receipt from the controller that controller is ready to be powered down, microcontroller powers down the RF devicemicrocontrollermemories, and optical scanning systemand enters power-conserving sleep mode, in accordance with the procedure previously described.

The datasheeg records data indicative of such traffic activity in memory, and once the other controller has been determined to be finished communicating with the optical imaging devices with the control region of the controllerthe controller analyzes the traffic data to determine how to fit i.


Also, relay is placed in the secondary circuit that supplies power to RMP Although the following Detailed Description will proceed with reference being made to specific embodiments of the present invention, it should be understood that the present invention is not intended to be limited to these embodiments. In addition to using power circuitrypower to RMP 12 can be provided by a solar cell mounted outside customer premises 5a wall-mounted adapter plugged into an outlet at the customer premises 5.

In response to appropriate control signals from the controllerthe first and second counters may be caused to load respective numerical scale factors, which have the effect of varying the respective frequencies of the pulses generated by the counters depending upon the value of the scale factors loaded into the counters.

These smoothed signals are transmitted to Gilbert doubly-balanced up converter mixer e. Network comprises bandpass and low pass filters which initially receives the baseband encoded signals from the processor Once these components have been powered up, the controller transmits to the microprocessor appropriate signals for indicating to the microprocessor that the collar portion has been removed from engagement with the face portion of the meter After passing through impedance matching network preferably comprising a plurality of capacitors, one or more inductors, and a plurality of microstrip lines, and designed to provide impedance matching at the central frequency of the spread spectrum signals intended to be received by the device between the output impedance of the switch and the input impedance of the low noise amplifierthe spread spectrum signals received by the antenna when the antenna is in receive mode are amplified by low noise amplifier Thus, by appropriately changing the scale factors loaded in the counter registers, the lock frequency of the VCO output signal may be changed to any arbitrary frequency within the VCO’s lock range.

Microcontroller is programmed via appropriate program code contained in the program memory to determine based upon the calculated temperature adjacent the electronic components on the mother board and RF deviceand the drift in tuning calibration expected to result therefrom stored in the memory look-up table to command the controller to adjust the spread spectrum transmission and reception frequencies to which the device is tuned, by controlling the synthesizer to generate feedback control signals which cause the frequency of the signals output by the VCO to be appropriately adjusted, in order to ensure that the RF device is in fact tuned to transmit and receive at the nominal spread spectrum central frequency to which it is desired to be set e.

The report time is programmed into the RDUs. Low power mode clock preferably comprises a In operation, the utility company computer 28 places a call over telephone line 26 to the telephone company central office 16 which in turn uses telephone company wide band link access 18 to gain access to wide band link Apparatus and method for reading gauges and other visual indicators in a process control system or other data collection system.

Thus, only during the answer window can the utility company recover usage information on demand. Rather, alternatively, if the device is modified in ways apparent to those skilled in the art, the controller may comprise a digitally programmable attenuator device that adjusts the power level of the control signals supplied to the amplifier based upon digital program signals supplied thereto by the microcontroller The Verma system comprises RDUs located at each customer’s premises for accumulating and reporting utility usage data from machine-readable utility meters at the premises, and a utility data processor or UDP located at the utility site for collecting the usage data sent from the RDUs over a conventional telephone network.

This embodiment is further provided with an adaptive calling process which is a means of moving the periodic interval at which the RMP automatically accesses information.


General purpose plastic rectifier 1n thru 1n vishay general semiconductor features. Voltage regulator is used to provide local power to decoder chip which provides 2-bit decoding of signal sent from RMP However, the various functional components of the host processor may alternatively be constructed out of custom, dedicated electronic hardware and software, without departing from this embodiment of the present invention.
