Abstract

Systems and methods for monitoring child seats and children in child seats through sensors paired with a central processing hub which in turn relays notifications of conditions to caregivers or other users based on a notification hierarchy and the urgency of the conditions detected.

Claims

1. A system for providing notifications of a condition relating to a child in vehicular child seat, the system comprising:

a sensor detecting a condition relating to a vehicular child seat or a child in said vehicular child seat when said vehicular child seat is installed in a vehicle;

a central hub comprising;

a transmitter/receiver receiving from said sensor a first datagram containing information related to said detected condition;

a microprocessor;

a non-transitory computer-readable medium having programming instructions which, when executed by said microprocessor, cause a second datagram to be formed containing notification information, said notification information based at least in part upon at least some of said information related to said detected condition contained in said first datagram;

a notification system receiving from said central hub said second datagram and conveying a notification to a user, said notification based at least in part upon at least some of said notification information in said second datagram.

2. The system of claim 1, wherein said sensor is selected from the group consisting of:

a three-axis accelerometer;

a force transducer; and

a temperature sensor.

3. The system of claim 1, wherein said condition is selected from the group consisting of:

the orientation of said vehicular child seat in said vehicle;

the tension on a safety restraint belt; and

, the air temperature near a child in said vehicular child seat.

4. The system of claim 1, wherein said central hub is a vehicular telematics system.

5. The system of claim 4, wherein said vehicular telematics system comprises a display and said notification system comprises said vehicular telematics system display.

6. The system of claim 5, wherein said notification is a graphical element displayed on said display.

7. The system of claim 1, wherein said notification system comprises a speaker and said notification comprises is a sound emitted by said speaker.

8. The system of claim 1, wherein said notification is a user-defined text message sent to a user-defined mobile telephone number.

9. The system of claim 1, wherein said notification is a user-defined e-mail message sent to a user-defined e-mail address.

10. The system of claim 1, wherein said non-transitory computer-readable medium further comprises notification hierarchy data comprising a plurality of notification addresses having associated notification priority data.

11. The system of claim 10, wherein said non-transitory computer-readable medium further comprises programming instructions which, when executed by said microprocessor, select from said notification hierarchy one or more addresses, said selection based at least in part on said associated notification priority data for said selected one or more addresses.

12. The system of claim 11, wherein each of said selected one or more addresses is a notification system receiving said second datagram and conveying a notification to a user, said notification based at least in part upon at least some of said notification information in said second datagram.

13. A method for notifying a user of a condition related to a child in a child seat comprising the steps of:

providing a child seat installable in a vehicle and comprising one or more sensors capable of detecting a condition related to a child when said child is in said child seat and said child seat is installed in said vehicle;

providing a central hub;

providing a notification system;

one or more of said one or more sensors detecting a condition related to a child in said child seat when said child seat is installed in a vehicle;

forming a first datagram comprising information related to said detected condition;

transmitting said first datagram to said central hub in a first transmission;

said central hub forming a second datagram comprising notification information, said notification information based at least in part upon at least some of said information related to said detected condition in said first datagram received by said central hub;

transmitting said second datagram to said notification system in a second transmission;

said notification system conveying a notification about said detected condition to a user, said notification based at least in part on at least some of said notification information in said second datagram received by said notification system.

14. The method of claim 13, wherein said sensor is selected from the group consisting of:

a three-axis accelerometer;

a force transducer; and

a temperature sensor.

15. The method of claim 13, wherein said condition is selected from the group consisting of:

the orientation of said vehicular child seat in said vehicle;

the tension on a safety restraint belt; and

, the air temperature near a child in said vehicular child seat.

16. The method of claim 13, wherein said central hub is a vehicular telematics system comprising a display and said notification system is said vehicular telematics system display.

17. The method of claim 13, said method further comprising the steps of:

providing a plurality of notification systems comprising said notification system;

providing a notification hierarchy comprising notification addresses and notification priority data for each notification system in said plurality of notification systems;

before transmitting said second datagram to said notification system in said second transmission, selecting said notification system from said plurality of notification systems, said selection based at least in part on said notification priority data associated with said notification system.

18. The method of claim 13, wherein said notification hierarchy comprises notification addresses and notification priority data supplied by a user.
