Abstract

A remote monitoring system offers both random tracking and scheduled contacts while the monitored person is away from home, and continuous signalling at home, permitting the monitored person to be monitored even while asleep, by providing a remote monitoring system which includes a home monitoring unit for receiving RF transmissions from a wrist device, but which can be self-installed by the wearer of the device. The home monitoring unit transmits periodic status reports concerning the presence of an individual at the location of the monitoring unit, but the direct telephone connection may be replaced by an Internet connection for all but urgent communications.

Claims

1. A monitoring system, comprising:

a monitoring unit having a communications link to a central monitoring station; and

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,

wherein said monitoring unit is arranged to determine, based on receipt of communications from said transmitter, whether a person wearing said device is within range of said monitoring unit, and to automatically report to the central monitoring station via said Internet communications link a result of said determination.

2. A system as claimed in claim 1, 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.

3. A system as claimed in claim 2, further comprising code converting 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.

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

5. 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 immediate attention, wherein step a.) is carried out by establishing an Internet data connection between the home monitoring unit and the central monitoring station, and step b.) is carried out by establishing a telephone link between the home monitoring unit and the central monitoring station.

6. A method as claimed in claim 5, wherein step b.) is carried out by establishing a direct telephone connection between the central monitoring station and the central monitoring unit.

7. A method as claimed in claim 5, 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 a local Internet access telephone number corresponding to the monitored person'"'"'s home telephone number and the selected ISP and downloading the local Internet access telephone number into the home monitoring unit for subsequent use in routine reporting and for selected exception reporting.
