Abstract

A pager-based alert system includes a monitor center that is in telephonic or data communication with a paging station allowing the command center to send multi-digit code words where selected digits comprise an address for selecting one or more of a plurality of physical units (paging receivers) and to direct the receiver to output visible and/or audible signals indicative of a particular alert condition. By providing the physical unit with graphic icons overlaying the visual indicators, an observer can readily determine the nature of the alert condition so that appropriate remedial action can be taken.

Claims

1. An electronic messaging system comprising:

(a) a plurality of physical units, each comprising;

(i) a microprocessor having a memory associated therewith,

(ii) a plurality of light sources controlled by the microprocessor;

(iii) an icon associated with each of said plurality of light sources; and

(iv) a paging receiver responsive to a predetermined RF carrier frequency transmitted by a paging terminal and adapted to receive encoded messages in accordance with a predetermined protocol from said paging terminal on a non-prioritized basis, said encoded messages including an address code and whereby said physical units can be grouped either on a geographical or logical basis in that only those physical units whose paging receiver is tuned to said predetermined carrier frequency, and having an address matching said address code, can forward the data to said microprocessor for causing the microprocessor to actuate more than one of the plurality of light sources simultaneously in accordance with the received data for illuminating selective ones of said icons, thereby providing notification of multiple alert conditions at a given time.

2. The electronic messaging system as in claim 1 wherein the light sources are selected from a group consisting of light-emitting diodes, liquid crystal displays, plasma displays and electro luminance displays.

3. The electronic messaging system as in claim 2 and wherein the icons are physically associated with predetermined ones of the plurality of light sources for providing a non-lingual indication of the predetermined alert conditions that are the subject of the received data.

4. The electronic messaging system as in claim 3 wherein selected ones of the plurality of light sources provide operational status of the electronic messaging system to a person observing a physical unit.

5. The electronic messaging system as in claim 3 wherein the electronic messaging system or portions thereof may be enabled or disabled from a remotely located monitoring center.

6. The electronic messaging system as in claim 2 and further including an auxiliary jack to enable the use of remote attention getting devices.

7. The electronic messaging system as in claim 6 wherein the microprocessor of the physical units may be remotely programmed from a monitoring center while located remotely from said monitoring center.

8. The electronic messaging system as in claim 2 and further including a alpha/numeric display for receiving text messages.

9. The electronic messaging system as in claim 1 wherein the light sources are liquid crystal displays.

10. The electronic message system as in claim 1 wherein the physical unit retains a historical log in said memory for past notifications received.

11. The electronic messaging system as in claim 1 and further including an audible signaling device controlled by the microprocessor.

12. The electronic messaging system as in claim 11 wherein the microprocessor includes a memory for storing a code list to which a given physical unit will respond when data from the paging terminal matches an entry in said code list.

13. The electronic messaging system as in claim 12 wherein the microprocessor is programmed to respond in a way dependent upon which entry in the code list is matched to selectively activate said visual and audible signaling devices.

14. The electronic messaging system as in claim 13 and further including a manual operable end user interface switch which, when actuated, sends a signal to the microprocessor for deactivating those signaling devices which the microprocessor allows to be end user deactivated.

15. The electronic messaging system as in claim 1 and further including an AC power source and having a DC battery backup in event of an AC power failure.

16. The electronic messaging system as in claim 15 wherein the battery backup is polarity insensitive.

17. An electronic messaging system comprising:

(a) a monitoring center for accepting alerts from authorized agencies;

(b) at least one paging terminal having the ability to broadcast a radio frequency carrier suitably modulated with information including addressing data and message data, said at least one paging terminal adapted to receive paging instructions from said monitoring center pertaining to an alert;

(c) a plurality of physical units grouped on either a geographical or a logical basis using said addressing data, each including

(i) a receiver tuned to said carrier frequency, the receiver including a demodulator for recovering the addressing data and message data,

(ii) a microprocessor coupled to the receiver to receive the addressing data and message data, the microprocessor having a memory for storing a code list,

(iii) a plurality of light sources controlled by the microprocessor, selected ones of the plurality of light sources being activated only when received addressing data matches entries in said code list and whereby multiple light sources can be simultaneously activated to signal multiple alert conditions at a given time; and

(iv) a fixed icon associated with each of said plurality of light sources and which, when illuminated provides a non-lingual notification of one or more predetermined alerts.

18. The electronic messaging system of claim 17 wherein the one(s) of the plurality of light sources activated is determined from said message data.

19. The electronic messaging system of claim 17 wherein the plurality of light sources include an individual array of light sources forming a predetermined pattern to enhance the attraction of attention by an observer that an alert condition is being signaled.

20. The electronic messaging system as in any one of claims 17, 18 and 19 and further including an audible alarm in the physical unit controlled by the microprocessor.

21. The electronic messaging system of claim 20 and further including a manually operated switch coupled to the microprocessor for selectively extinguishing the audible alarm and predetermined ones of the visual indicating devices.

22. The electronic messaging system as in claim 20 wherein the audible alarm can operate in a plurality of modes.

23. The electronic messaging system as in claim 17 wherein the addressing data includes a cap code associated with a carrier frequency to which a physical unit may be tuned.

24. The electronic messaging system of claim 17 wherein selected ones of the plurality of light sources provide an indication of operating status of the electronic messaging system.

25. The electronic messaging system of claim 17 wherein the monitoring center is coupled through one of a public switched telephone network and a data network to the paging terminal.

26. The electronic messaging system of claim 17 wherein message data includes a test code for causing one of the plurality of visual signaling devices of the physical unit to be activated when the paging terminal and the receiver, the microprocessor and the visual signaling devices are operational.

27. The electronic messaging system of claim 17 wherein the end to end system tests and alerts may be performed on an individual, group, or global basis.

28. The electronic messaging system as in claim 17 wherein the plurality of light sources are each capable of operating in at least three distinct modes.

29. The electronic messaging system as in claim 17 wherein status of the plurality of light sources and audible indicating devices may be changed remotely from the monitoring center.
