Abstract

Systems and methods which provide for an alarm or notification that a child is in a car seat. The systems generally determine if a child is in the seat and that the seat, and therefore the vehicle, is not in motion. Upon detecting both situations, the notification or alarm is activated.

Claims (17)

1. A child car seat and notification device, in combination, comprising:

a sensor integral with said child car seat;

an accelerometer;

a notification system; and

a controller;

wherein

if said sensor detects a child in said child car seat and said accelerometer detects repeated acceleration along a fixed axis, then said controller does not activate said notification system; and

if said sensor does not detect a child in said child car seat and said accelerometer detects repeated acceleration along a fixed axis, then said controller activates said notification system to provide a first notification.

2. The combination of claim 1 wherein if said sensor does detect a child in said child car seat and said accelerometer does not detect repeated acceleration along a fixed axis, then said controller activates said notification system to provide a second notification.

3. The combination of claim 2 wherein said first notification and said second notification are the same.

4. The combination of claim 2 wherein said first notification and said second notification are different.

5. The combination of claim 1 wherein said sensor is a pressure sensor.

6. The combination of claim 1 wherein said sensor is an optical sensor.

7. The combination of claim 1 wherein said sensor detects that a buckle has been fastened about said child.

8. The combination of claim 1 wherein said accelerometer is not integral to said car seat.

9. The combination of claim 1 wherein said controller is not integral to said car seat.

10. The combination of claim 1 wherein said notification system is not integral to said car seat.
