Abstract

A monitoring and notification system provides for monitoring of people based on a normal activity of a device associated with the monitored people. The monitoring and notification system includes a monitoring and notification device that is coupled to a network. A plurality of terminals are also coupled to the network and the monitoring and notification device monitors any number of the terminals. When an “inactivity event” of the monitored terminal(s) is detected, the monitoring and notification device notifies other ones of the terminals of the inactivity event.

Claims

1. A method for monitoring a person based on a network usage, comprising:

generating an activity record of the person by monitoring at least one device;

comparing the activity record of the person with an expected activity record to determine the existence of an inactivity event associated with the person;

generating an inactivity signal based on a profile and the inactivity event; and

transmitting at least one notification message in the network if the inactivity signal is generated.

2. The method of claim 1, wherein the monitoring step comprises:

detecting whether the terminal generated a first signal; and

generating a terminal active signal if the first signal is not in response to a second signal received by the terminal.

3. The method of claim 2, wherein the terminal is connected to a plurality of communication lines, the terminal active signal being generated after the first signal is generated on one of a portion of the communication lines as specified in a profile.

4. The method of claim 3, wherein the monitoring step monitors a plurality of terminals, the terminal active signal being generated after the first signal is generated on one of a portion of the terminals as specified in the profile.

5. The method of claim 3, wherein the profile includes a time threshold, the generating step generating the inactive signal when a time after an active signal is greater than the time threshold without the detection of another active signal.

6. The method of claim 5, wherein the profile identifies at least one notification terminal, the transmitting step transmitting the notification message to the notification terminal when the inactive signal is generated.

7. The method of claim 5, wherein the profile identifies a plurality of notification terminals, the transmitting step transmitting the notification message to each of the notification terminals.

8. The method of claim 7, wherein the transmitting step transmits the notification message to each of the notification terminals until either each of the notification terminals answers or a limit is reached, the limit being included in the profile.

9. The method of claim 8, wherein the transmitting step transmits the notification message to a default notification terminal after the limit is reached.

10. The method of claim 8, wherein the limit is either a predetermined time interval or a predetermined number of times.

11. The method of claim 1, wherein the at least one terminal includes at least one of a telephone station and a computer.

12. The method of claim 1, wherein the notification message is transmitted by either a monitoring and notification device or an operator.

13. A system that monitors a person'"'"'s usage of a network, comprising:

a controller generating an activity record of the person by monitoring at least one device, coupled to the network, wherein the activity record of the person is compared with an expected activity record to determine the existence of an inactivity event associated with a person, wherein an inactivity signal is generated based on a profile and the inactivity event, and wherein at least one notification message is transmitted in the network if the inactivity signal is generated.

14. The system of claim 13, wherein the monitoring and notification device detects whether the terminal generated a first signal, and generates a terminal active signal if the first signal is not in response to a second signal received by the terminal.

15. The system of claim 14, wherein the terminal is connected to a plurality of communication lines, the terminal active signal being generated after the first signal is generated on one of a portion of the communication lines as specified in a profile.

16. The system of claim 15, wherein the monitoring and notification device monitors a plurality of terminals, the terminal active signal being generated after the first signal is generated on one of a portion of the terminals as specified in the profile.

17. The system of claim 15, wherein the profile includes a time threshold, the monitoring and notification device generating the inactive signal when a time after an active signal is greater than the time threshold without the detection of another active signal.

18. The system of claim 17, wherein the profile identifies at least one notification terminal, the monitoring and notification device transmitting the notification message to the notification terminal when the inactive signal is generated.

19. The system of claim 17, wherein the profile identifies a plurality of notification terminals, the monitoring and notification device transmitting the notification message to each of the notification terminals.

20. The system of claim 19, wherein the monitoring and notification device transmits the notification message to each of the notification terminals until either each of the notification terminals answers or a limit is reached, the limit being included in the profile.

21. The system of claim 20, wherein the monitoring and notification device transmits the notification message to a default notification terminal after the limit is reached.

22. The system of claim 20, wherein the limit is either a predetermined time interval or a predetermined number of times.

23. The system of claim 13, wherein the at least one terminal includes at least one of a telephone station and a computer.

24. The system of claim 13, wherein the notification message is transmitted by either a monitoring and notification device or an operator.

25. The system of claim 13, wherein the monitoring and notification device is incorporated in the terminal being monitored.

26. The system of claim 13, wherein the network includes a wired network or a wireless network or a combination of both, and the terminals are coupled to the network through wired connections or wireless connections.

27. A system that monitors a person'"'"'s usage of a network, comprising:

monitoring means to generate an activity record of the person by monitoring at least one device coupled to the network;

comparison means to compare the activity record of the person with an expected activity record to determine the existence of an inactivity event associated with a person;

generation means for an inactivity signal based on a profile and the inactivity event; and

transmission means for at least one notification message in the network if the inactivity signal is generated.
