摘要： A microcomputerized postage meter has a programmable clock for generating an interrupt output to the microcomputer in the event that it times out before it is stopped or reprogrammed. The timer is suitably programmed for the anticipated duration of the routine to enable swift recovery from the postage meter microcomputer being locked into operation in an infinite loop.

摘要： A system for the nonvolatile storage of data, such as a postage meter system, includes a microcomputer coupled to an MNOS type nonvolatile memory and also coupled to an EEPROM type nonvolatile memory, each memory having address lines and data lines. The address lines and data lines of the two nonvolatile memories are coupled to microcomputer ports such that the MNOS memory data lines are always at a high value whenever the EEPROM memory is addressed for the purpose of either writing or reading.The EEPROM nonvolatile memory control terminals and the MNOS nonvolatile memory control terminals are coupled to different ports of the microcomputer. Access to the MNOS nonvolatile memory is achieved by input/output mapping techniques. Access to the EEPROM nonvolatile memory is achieved by memory mapping techniques. In this way, protection is provided against inadvertently accessing the wrong memory or wrong address while executing read/write instructions to a selected memory.

摘要： An electronic postage meter includes a microcomputer with an external timer for providing a periodic interrupt. At each interrupt, a monitor routine examines the sensors and switches for changes in status and a monitor word is formed in correspondence with the detected status. A queue of meter tasks is scheduled in accordance with the meter status, any changes in status, or after a selected time has passed.

摘要： A security system for a postage meter includes two memories, one of which is an electronically programmable READ-ONLY memory having non-volatile storage, while the second memory is a shadow RAM which is a composite memory having a first section composed of a volatile RAM and a second section composed of non-volatile storage. During a power outage, a computer strobes the second memory to transfer data from the volatile section to the non-volatile section. Upon restoration of the power, a transfer circuit which includes a detector of the incoming power directs the transfer of at least a portion of the stored data in each of the memories to the computer for a comparison to determine if any data has been altered by the loss of power.

摘要： An improved input/output channel for linking a computer control unit for an electronic postal meter to input/output units. The invention includes a converter for converting unit-output electrical signals to non-conductive carrier signals and for converting the non-conductive carrier unit-input signals back to electrical signals. Non-conducting means are used to transmit the signals between the meter and the input/output units so that any attempts to interfere with meter operation will, of necessity, involve physical evidence of tampering, observable to an inspector.

摘要： An electronic postal meter system is separated into a meter unit and an input/output control unit. The two units are linked by a communications link which preferably uses light transmitting fibers to transmit data and instructions. The meter unit is used to process and store only that data which pertains to the critical accounting functions of the meter or to the control of the printer driven by the electronics control within the meter unit. Less critical functions, such as zip-to-zone conversions, are restricted to the less secure control unit. By restricting the meter unit to highly critical data and by enclosing only the meter unit in a secure housing, the overall security of the meter system is enhanced. Novel failure detect circuitry for a printer setting detector array and a novel event-indicating signal generator circuit are disclosed. The significant routines employed in the operation of the meter system are described.

摘要： A date printing device, such as a postal meter, includes an electronic calendar clock which generates and stores signals representing different days and months of the year. The electronic calendar clock provides one input to a comparison circuit. Another input to the comparison circuit is provided by an encoder which generates signals representing the current setting of the date printing device. The comparison circuit samples inputs from the calendar clock and the encoder and generates a control signal when a mismatch is detected.
