Abstract

Sensors are used to detect data representing the current state of at least one monitored phenomena. The time available for a human being to make a judgment concerning the detected phenomena is determined and an appropriate number of messages corresponding to the current state of the monitored phenomena is determined for output. At the same time, the priority of each of the messages to be displayed is determined. The number of messages deemed to be appropriate are output and displayed in the order of priority.

Claims

1. A message display apparatus comprising:

at least one sensor which outputs data representing a current state of at least one monitored phenomenon;

first means, responsive to an output of said at least one sensor, for determining one or more display elements corresponding to a sensed state of said at least one monitored phenomenon and for determining a priority ranking of each display element corresponding to the sensed state of said at least one phenomenon;

second means, responsive to the output of said at least one sensor, for calculating a time allowance within which a human being must make a judgment regarding the sensed state of said at least one monitored phenomenon; and

third means responsive to outputs of said first and second means for establishing a form of a display.

2. A message display apparatus as in claim 1, wherein said third means selects which display elements from said first means are to be displayed based on the priority ranking determined for each display element by said first means.

3. A message display apparatus as in claim 2, wherein said third means further determines the form of display of those selected display elements based on the selected display elements and the time allowance calculated by said second means.

4. A message display apparatus as in claim 1, further comprising a plurality of sensors which output data representing the current state of at least one monitored phenomenon, said first means being responsive to outputs of said plurality of sensors for determining one or more display elements corresponding to the sensed state of said at least one monitored phenomenon and for determining the priority ranking of each display element corresponding to the sensed state of said at least one monitored phenomenon, said second means being responsive to the outputs of said plurality of sensors for calculating the time allowance within which a human must make a judgment regarding the sensed state of said at least one monitored phenomenon.

5. A message display apparatus as in claim 1, further comprising a plurality of sensors which output data representing the current state of a plurality of monitored phenomenon, said first means being responsive to outputs of said plurality of sensors for determining one or more display elements corresponding to the sensed states of said plurality of monitored phenomenon and for determining the priority ranking of each display element corresponding to the sensed states of said plurality of monitored phenomenon and for determining the priority ranking of each display element corresponding to the sensed state of said plurality of monitored phenomenon, said second means being responsive to the outputs of said plurality of sensors for calculating the time allowance within which a human must make a judgment regarding the sensed states of said plurality of monitored phenomenon.

6. A message display apparatus as in claim 1, wherein said second means comprises inference means for calculating said time allowance using fuzzy inferences based on rule membership functions.

7. A message display apparatus as in claim 1, wherein said first means comprises inference means for determining said one or more display elements and said priority ranking using fuzzy inferences based on rule membership functions.

8. A message display apparatus as in claim 7, further comprising a plurality of sensors which output data representing the current state of at least one monitored phenomenon, said first means being responsive to the outputs of said plurality of sensors in determining said time allowance.

9. A message display apparatus as in claim 7, further comprising a plurality of sensors which output data representing the current states of a plurality of monitored phenomenon, said first means being responsive to the outputs of said plurality of sensors in determining said time allowance.

10. A message display apparatus comprising:

at least one sensor which outputs data representing a current state of at least one monitored phenomenon;

first means, responsive to the output of said at least one sensor, for determining a time allowance within which a human being must make a judgment concerning said at least one monitored phenomenon, said first means comprising inference means which makes fuzzy inferences based on said current state to determine said time allowance;

second means, for calculating a number of messages which can be output within the time allowance determined by said first means; and

third means for outputting messages, said third means containing a number of pre-stored messages, said third means including means for outputting a number of said pre-stored messages corresponding to the number of messages calculated by said second means.

11. A message display apparatus as in claim 10, further comprising a plurality of sensors which output data representing the current state of at least one monitored phenomenon, said first means being responsive to the outputs of said plurality of sensors for determining said priority ranking.

12. A message display apparatus as in claim 10, further comprising a plurality of sensors which output data representing the current states of a plurality of monitored phenomenon, said first means being responsive to the outputs of said plurality of sensors for determining said priority ranking.

13. A message display apparatus comprising:

at least one sensor which outputs data representing a current state of at least one monitored phenomenon;

means for storing a plurality of display elements associated with the current state of said at least one monitored phenomenon;

first means, responsive to the output of said at least one sensor, for determining a priority ranking of said display elements, said first means comprising inference means which makes fuzzy inferences based on said current state to decide the ranking of each display element; and

second means for determining which of said display elements to display according to the priority ranking determined by said first means.

14. A message display apparatus as in claim 13, further comprising a plurality of sensors which output data representing the current state of at least one monitored phenomenon, said first means being responsive to the outputs of said plurality of sensors in determining said plurality of possible display elements.

15. A message display apparatus as in claim 13, further a plurality of sensors which output data representing the current states of a plurality of monitored phenomenon, said first means being responsive to the outputs of said plurality of sensors in determining said plurality of possible display elements.

16. A message display apparatus as in claim 13, wherein said second means determines that fewer of said possible display items are to be displayed as the urgency of the current state increases.

17. A message display apparatus comprising:

at least one sensor which outputs a current state of at least one monitored phenomenon;

first means responsive to the outputs of said at least one sensor for determining a plurality of possible display elements corresponding to the current state of said at least one monitored phenomenon;

second means, for calculating a number of said possible display items which are to be displayed, said second means comprising inference means which makes fuzzy inferences based on said current state to determine the number of possible display items based on an urgency of the current state; and

third means for outputting the number of display elements calculated by said second means.
