Abstract

The system and the method of the present invention allows a person in charge (P) to monitor, and to act on, the activity level, physical or cerebral, and the comfort level of one ore more subject (S) simultaneously, from a distance, by the provision of a combination of sensors, at least one processing unit, a communication unit vice and at least one control unit, whereby depending on a specific needs of the subject, complementary sensors are selected to measure complementary parameters of the subject (S) and/or of the subject'"'"'s environment (E) and to process and interpret these measured parameters so as to assess a level of global or localized comfort, in such a way that these parameters are available to the person in charge (P).

Claims

wherein said at least one data acquisition unit further comprises devices selected in the group consisting of a microphone, a loudspeaker, a radio receiver, a radio transmitter, a camera and a video transmitter; and

wherein said at least one control unit comprises modules selected in the group consisting of sound modules and audio/video modules.

2. The system according to claim 1, wherein said set of sensors comprises main sensors selected in the group consisting of movement sensors and cerebral activity sensors, and complementary sensors selected in the group consisting of G sensor, GPS, tilt sensor, infrared sensor, echo sensors, magnetic sensoelectrodes, temperature probe, moisture meter, sound environment sensor and body imaging device.

3. The system according to claim 1, wherein said at least one data acquisition unit further comprises a signal-processor receiving data from said set of sensors, and an activity modulator connected to said signal-processor.

4. The system according to claim 1, wherein said at least one control unit comprises a communication device and a user interface.

5. The system according to claim 4, wherein said communication device comprises a signal processor including a memory and processing means.

6. The system according to claim 4, wherein said communication device is connected to a network.

7. The system according to claim 4, wherein said communication device allows adjusting a transmission power between the data acquisition unit and the control unit.

8. The system according to claim 1, further comprising a transport unit, which allows said at least one data acquisition unit to keep track of the activity of the at least one subject, and an environment unit which allows keeping track of environmental parameters.

13. The system according to claim 4, wherein said user interface allows a person in charge of the at least one subject to be informed of a state thereof, to order a retroaction according to the state of the at least one subject and to request complementary data selected in the group consisting of sound levels and video images.

14. The system according to claims 2 and 9, wherein the temperature probe allows measuring a cutaneous temperature of the subject and comparing it to a reference temperature set as a comfort temperature zone.

15. The system according to claim 14, wherein the comfort temperature zone is updated in relation to characteristics of the at least one subject selected in the group consisting of its age, its size, a proper sensitivity thereof, its state of health.

16. The system according to anyone of claims 2 and 9, wherein the set of sensors is maintained in a close relationship with the at least one subject'"'"'s body.

17. The system according to anyone of claims 1 and 9, wherein said at least one control unit receives signals of a state of the at least one subject at intervals and provides alerts.

18. The system according to claim 17, wherein the alarms are triggered by states selected in the group consisting of awaking of the at least one subject, absence of movement after a predetermined delay and position variations.

19. The system according to anyone of claims 1 and 9, wherein activity comprises activities selected in the group consisting of rest, physical activity, absence of a movement, absence of respiration, a sleeping state, an awaken state, an active state, an intense active state, an intermediate active state and cerebral activity, and monitoring comprises an assessment of an intensity and of a nature of the activity from a distance.

20. The system according to any one of claims 1 and 9, wherein said data acquisition unit is integrated in a portable assembly.
