Abstract
A child safety seat accident detection system that has a device such as an accelerometer for determining an acceleration of the seat, and a processor, operably connected to the device for determining an acceleration of the seat, and that is configured to judge, based at least on the determined acceleration, if the seat has been in a motor vehicle accident.
Claims19
A child safety seat accident detection system, comprising:
- a device for determining an acceleration of the seat;
- and
- a processor, operably connected to the device for determining an acceleration of the seat, and that is configured to judge, based at least on the determined acceleration, if the seat has been in a motor vehicle accident,
- wherein the device for determining an acceleration of the seat comprises an inertial measurement unit (IMU) that comprises at least one accelerometer and at least one rotation sensor.

A child safety seat accident detection system, comprising:
- an inertial measurement unit (IMU) that comprises at least one accelerometer for detecting acceleration and at least one rotation sensor for detecting rotation, where the IMU is located in or on the child safety seat;
- a processor, operably connected to the IMU, and that is configured to judge, based at least on one of a determined acceleration and a determined rotation, if the seat has been in a motor vehicle accident,
- wherein the processor is configured to judge if the seat has been in a motor vehicle accident based on both the determined acceleration and a time over which an acceleration has occurred,
- wherein the processor judges that the seat has been in a motor vehicle accident if the determined acceleration at least meets a threshold acceleration, and the time is less than a threshold time, and
- wherein the processor judges that the seat has not been in a motor vehicle accident if the determined acceleration is less than the threshold acceleration, or the time is at least as great as the threshold time;
- a global positioning system (GPS) device that is configured to determine a position of the child safety seat and provide the position to the processor, wherein the GPS device comprises a GPS antenna and a GPS sensor operably connected to the GPS antenna, wherein the GPS antenna is configured to receive GPS satellite signals, and the GPS sensor is configured to determine a position based on the satellite signals and input position information to the processor;
- and
- a wireless communication device that is operably coupled to the processor, wherein the wireless communication device is configured to send an accident notification to a third party, wherein the accident notification includes the position of the child safety seat.
