AMENDED CLAIMS
[received by the International Bureau on 1 February 1999 (01.02.99);
original claims 1, 12 and 16 amended; remaining claims unchanged (5 pages)]

1 . A monitoring system, comprising:
a monitoring unit having a communications link to a central monitoring station;
a device arranged to be worn by a person, said device including; processor means for calculating a code;
means for converting said code into a format in which said code can be directly communicated to the central monitoring station over an existing communications medium without intervention by the monitoring unit; and
a transmitter in addition to said code converting means for communicating with the monitoring unit.

2. A system as claimed in claim 1 , wherein said transmitter is an RF transmitter arranged to transmit RF signals to the monitoring unit when the transmitter is within range of the monitoring unit, thereby providing for continuous monitoring of the person wearing the device so long as the person is scheduled to be within range of the monitoring unit.

3. A system as claimed in claim 2, wherein said transmitter is arranged to transmit RF signals to the monitoring unit continuously.

4. A system as claimed in claim 2, wherein said transmitter is arranged to transmit RF signals to the monitoring unit at random intervals during scheduled sleep periods of the person wearing the device, and wherein said means for converting said code into a format for direct transmission to the central monitoring station comprises a tone generator arranged to generate a sequence of tones corresponding to said code for transmission to the central monitoring station over the telephone line when the device is held up to a telephone receiver in order to monitor said person wearing the device at times other than said scheduled sleep periods.

5. A system as claimed in claim 2, wherein said means for converting said code into a format for direct transmission to the central monitoring station comprises a tone generator arranged to generate a sequence of tones corresponding to said code, whereby when the device is held up to a telephone receiver, the sequence of tones is transmitted directly to the central monitoring station over the telephone line, and whereby a location of the caller can thereby be determined using automated number identification, to provide random tracking of the person wearing the device in addition to said continuous monitoring.

6. A system as claimed in claim 1 , wherein the monitoring unit further comprises means including a speech synthesizer and speaker for communicating installation instructions to a person installing the monitoring unit.

7. A system as claimed in claim 1 , wherein said monitoring unit is connected to the central monitoring station by an Internet data connection.

8. A system as claimed in claim 1 , wherein said monitoring unit is connected to the central monitoring station by a direct telephone connection.

9. A system as claimed in claim 1 , wherein said monitoring unit is connected to the central monitoring station by both a direct telephone connection and an Internet data connection.

10. A monitoring system, comprising:
a monitoring unit having a communications link to a central monitoring station;
a device arranged to be worn by a person, said device including a transmitter for communicating with the monitoring unit, wherein said communications link is an Internet communications link.

1 1. A system as claimed in claim 10, wherein said transmitter is an RF transmitter arranged to periodically transmit RF signals to the monitoring unit whenever the transmitter is within range of the monitoring unit, thereby providing for effectively monitoring of the person wearing the device so long as the person is within range of the monitoring unit.

12. A system as claimed in claim 1 1 , further comprising means for converting said code into a format for direct transmission to the central monitoring station, said code converting means comprising a tone generator arranged to generate a sequence of tones corresponding to said code, whereby when the device is held up to a telephone receiver, the sequence of tones is transmitted directly to the central monitoring station over the telephone line, and whereby a location of the caller can thereby be determined using Automatic Number Identification (ANI), to provide random tracking of the person wearing the device in addition to said continuous monitoring.

13. A system as claimed in claim 10, wherein the monitoring unit further comprises means including a speech synthesizer and speaker for communicating installation instructions.

14. A method of remotely monitoring a person wearing a device which transmits signals to a home monitoring unit when in range, comprising the steps of a.) periodically reporting a status of the home monitoring unit and whether said signals are being received to a central monitoring station, and b.) reporting on an urgent basis conditions requiring immediately attention, wherein step a.) is carried out by establishing an Internet data connection between the home monitoring unit and the central monitoring station.

15. A method as claimed in claim 14, wherein step b.) is carried out by establishing a direct telephone connection between the central monitoring station and the central monitoring unit.

16. A method as claimed in claim 14, wherein the monitoring unit is programmed with the central monitoring station's direct telephone number, which the monitoring unit uses to make all reports until the central station recognizes, using caller I.D. or automatic number identification (ANI) that the report call had been received from a valid enrolled home telephone number of a person who is being monitored, and further comprising the step of, once the report call has been recognized as originating from a valid enrolled home telephone number, automatically looking up the local Internet access telephone number corresponding to the monitored person's home telephone number and the selected ISP and

27 downloading the local Internet access telephone number into the home monitoring unit for subsequent use in routine reporting and for selected exception reporting.
