Abstract

In a data processing system wherein operator entry of data is provided an array of alpha numeric display units is utilized not only for indicating operand entries and operating results, but also as an operator message prompting medium for steering the operator to correct operand entry or system errors. Upon processor recognition of a particular entry or other errors an assigned error signal is generated which blocks the operand or operation result signal from the display units. In one embodiment the error signal is received at a programable logic array associated with each display unit to provide a signal for accessing a memory which in turn provides the appropriate letter pattern signal for the display unit to spell out an error prompt message. An alternate embodiment provides for serial generation of the letter pattern signals for each display unit and rapid sequential actuation of the display units to spell the prompt message.

Claims

1. In a processing system comprising a data processor, operator input means operatively connected to the processor for transmitting data to the processor and display means operatively connected to the processor for visually indicating numeric data, the processor receiving data from the operator input means and processing the received data to provide numeric display signals, the display means receiving the numeric display signals and in response thereto visually indicating corresponding numeric data and with a plurality of possible error conditions existing in conjunction with the processor, the improvement comprising an operator prompting system, the processor including means for detecting an error condition and providing an error signal indicative of the presence of such condition, the prompting system including generating means for receiving the error signal and in response thereto generating a message signal, the display means including means receiving the message signal and in response thereto visually indicating the nature of the error condition as an alphabetically spelled phonetic operator prompt message, the prompting system further including means for receiving the error signal and in response thereto preventing the numeric display data signals from being received by the display means, whereby the operator is apprised of the nature and existence of the particular error condition without distraction of attention from the normal data entry routine.

2. An operator prompting system constructed in accordance with claim 1 further including error emphasis means, the emphasis means receiving the error signal and in response thereto providing a display control signal oscillating at an operator observable rate whereby the operator prompt message is intermittently blinked at the display to emphasize the presence of an error condition.

3. An operator prompting system constructed in accordance with claim 1 wherein the means generating the message signal receives one of a plurality of error signals, each error signal being correlated to a particular error condition, the generating means generating one of a plurality of message signals corresponding to the one error signal, the display means alphabetically spelling a phonetic operator prompt message corresponding to each message signal received.

4. An operator prompting system constructed in accordance with claim 3 wherein the display means comprises a plurality of display units, each message signal comprising a plurality of segment signals corresponding to alphabetic letters, each of the segment signals being received at a different display unit, the display units conjunctively spelling the phonetic prompt message.

5. An operator prompting system constructed in accordance with claim 4 wherein the means generating message signals includes a plurality of means storing the message signals, each storing means generating segment signals associated with a different display unit.

6. An operator prompting system constructed in accordance with claim 5 wherein the storing means further includes a logic array, the logic array receiving a particular error signal and in response thereto providing a corresponding access signal, the memory receiving the access signal and in response thereto generating the message signal.

7. An operator prompting system constructed in accordance with claim 4 wherein the segment signals are transmitted serially, the system further including sequencing means for providing control signals, the generating means receiving the control signals and in response thereto generating the segment signals.

8. An operator prompting system constructed in accordance with claim 7 wherein the generating means includes a logic array for storing the message signals.

9. An operator prompting system constructed in accordance with claim 2 wherein the emphasis means includes oscillating means and gate means, the oscillating means providing a signal oscillating at the operator observable rate, the gate means receiving the oscillating signal and the error signal and in response thereto providing the display control signal.

10. A method of advising an operator of the presence of one of a plurality of possible error conditions in an automated mailing system including input means for entering mailing data signals, processing means receiving the mailing data signals and a display for providing a visual indication of numeric data, the method comprising the steps of

(a) storing a plurality of error identification data,

(b) detecting the presence of a particular error condition,

(c) preventing numeric data from being indicated at the display upon detection of such error condition,

(d) retrieving error identification data corresponding to the error condition detected from the stored identification data, and

(e) utilizing the retrieved error condition identification data, actuating the display to alphabetically spell a phonetic operator informative message for correction of the detected error condition.

whereby the operator is directed to rectify the error condition without any distraction of attention from the display.

11. A method of advising an operator of the presence of an error condition in a data processing system as set forth in claim 10 further including the step of blinking the message at an operator observable rate to thereby emphasize the presence of the error condition.

12. In an automated mailing system including input means for entering mailing data signals requisite for the calculation of postage for an article, display means for providing a visual indication of numeric data and processing means receiving the mailing data signals, the processing means including memory means adapted to store postage rate data, the processing means calculating the requisite postage for the article as a function of the mailing data signals and the postage rate data, the processing means being operatively connected to the display means and transmitting numeric display data signals to the display means, the display means visually indicating numeric values in response to the numeric display data signals and with a plurality of possible error conditions existing in conjunction with the processing of inappropriate mailing data signals, the improvement comprising an operator prompting system, the processing means including means for detecting any of a plurality of possible error conditions and providing an error signal indicative of the presence of the detected error condition, the prompting system including generating means for receiving the error signal correlated to the particular error condition detected, the generating means generating a message signal corresponding to the particular error signal received, the display means receiving the message signal and in response thereto alphabetically spelling a phonetic operator prompt message corresponding to the message signal received, the prompting system further including means for receiving the error signal and in response thereto inhibiting the display of numeric values by the display means, whereby the operator is apprised of the nature and existence of a particular error condition without distraction of attention from the normal mailing system data entry routine.

13. An automated mailing system as constructed in accordance with claim 12 wherein the input means includes means for operator entry of postage rate accessing data.

14. An automated mailing system as constructed in accordance with claim 13 wherein the mailing data includes article weight data, the input means including scale means for weighing the article and generating a weight indicative signal, the mailing data signals including the weight indicative signal.
