Abstract

A monitor system for monitoring an environment inhabited by an occupant, the system comprises a controller having data storage means, a processor, data processing software, at least one input, and at least one output, wherein one at least one input comprises an output signal from a signal generator associated with a utility meter, the utility meter being arranged to meter a utility entering the monitored environment, wherein the said data processing software records and analyses the or each at least one input, and wherein said at least one output includes an alarm signal generated when the data processing software determines that the utility use pattern is abnormal.

Claims

1. A monitor system for monitoring an environment inhabited by an occupant, the system comprising a controller having data storage means, a processor, data processing software, at least one input, and at least one output, wherein one at least one input comprises an output signal from a signal generator associated with a utility meter, the utility meter being arranged to meter a utility entering the monitored environment, wherein the said data processing software records and analyses the or each at least one input, and wherein said at least one output includes an alarm signal generated when the data processing software determines that a utility use pattern is abnormal.

2. A monitor system according to claim 1, including at least one motion sensor located in the environment, wherein the said at least one input includes an output signal from the at least one motion sensor.

3. A monitor system according to according to claim 1, including at least one switch associated with an exit door of the said environment, and wherein said at least one input includes an output signal from the at least one switch, said switch changing its open/closed status upon opening or closing of its associated exit door.

4. A monitor system according to claim 1, wherein said at least one input includes a signal from a manually operable alarm raise switch, and wherein when the said switch is activated the controller generates an alarm signal.

5. A monitor system according to claim 4, wherein the manually operable alarm raise switch is located on a remote control device, which transmits a signal to a receiver connected to the controller upon activation of said alarm raise switch.

6. A monitor system according to claim 1, wherein said plurality of inputs includes a signal from a monitor system de-activation switch, and wherein upon receipt of such a signal by the controller, the monitor system is switched off.

7. A monitor system according to claim 1, wherein said plurality of inputs includes a signal from an alarm reset switch, and wherein said reset switch is activated when the reset switch is activated upon generation of said alarm signal, and wherein changing the status of said alarm reset switch de-activates the said alarm signal.

8. A monitor system according to claim 1, wherein upon generation of said alarm signal, the data processing software activates an alarm warning.

9. A monitor system according to claim 8, wherein the said alarm warning comprises an assistance summoning tele-transmissible signal.

10. A monitor system according to claim 8, wherein said alarm warning includes a warning device in the environment selected from the group comprising:

an audible warning, a visual warning, or a touch stimulus.

11. A monitor system according to claim 1, wherein the metered utility is selected from the group comprising:

water, gas and electricity.

12. A monitor system according to claim 1, wherein said analysis of the or each input includes the step of identifying signatures of individual utility uses.

13. A monitor system according to claim 12, wherein the data processing software is programmed with signatures of a plurality of specific utility uses, and wherein recorded utility uses are compared with said signatures, and identified as a specific utility uses when a recorded usage is within a predetermined threshold of the signature of that specific utility usage.

14. A monitor system according to claim 12, wherein signature identified utility uses are recorded, and the recorded use is compared with data representing normal utility use, and when said recorded utility use in a period deviates from normal utility use by a threshold value, said deviation above the threshold is identified in the recorded data.

15. A monitor system according to claim 14, wherein changing use of a utility during said period indicates failing health of the occupant of the environment, and upon detection of such changing use, the data processing software generates a signal indicating said changing use for transmission to health professional.

16. A monitor system according to claim 12, wherein signatures are identified as utility uses requiring or not requiring the presence of an occupant in the environment.

17. A monitor according to claim 1, wherein the data processing software receives an input from a motion sensor, wherein detected motion indicates the presence of an occupant in the environment.

18. A monitor system according to claim 17, wherein the data processing software receives an input from a switch associated with an exit door of the environment, wherein the on/off status of the switch represents the open/closed status of the associated exit door, wherein the data processing software analyses signals from the switch and said motion sensor to determine that an occupant has exited the environment.

19. A monitor system according to claim 18, wherein the said motion sensor is located in the vicinity of said exit door, and wherein the data processing software continuously analyses signals from said motion sensor, and by detection of motion after detection of an occupant exiting the environment, detects that the environment nevertheless remains occupied.

20. A monitor system according to claim 1, wherein abnormal utility use is constituted by substantially no use of said utility during a predetermined period.

21. A monitor system according to claim 1, wherein the said data processing software includes a statistical analyses facility, which facility establishes a statistical distribution of utility use in the environment, and wherein abnormal utility use is determined to occur when the time between utility uses approaches a predetermined threshold statistical value.

22. A computer program comprising program instructions for operating a monitor system for monitoring an environment inhabited by an occupant, the system comprising a controller having data storage means, a processor, data processing software, at least one input, and at least one output, wherein one at least one input comprises an output signal from a signal generator associated with a utility meter, the utility meter being arranged to meter a utility entering the monitored environment, wherein the said data processing software records and analyses the or each at least one input, and wherein said at least one output includes an alarm signal generated when the data processing software determines that a utility use pattern is abnormal.
