Abstract

A child car seat is provided, comprising a base; a seat coupled to the base; and a sensor device mounted to the base or the seat, the sensor device including a sensor that outputs a measurement signal indicating whether a child is present in the seat, a processor that receives the measurement signal and determines whether a child is present, and a communication circuit that transmits a proximity signal configured for reception by a first mobile device. The proximity signal causes a first alert to be communicated to the first mobile device in response to the first mobile device exceeding a range from the sensor device, and a second alert to be communicated to a second mobile device if, after a threshold amount of time, the measurement signal continues to indicate that a child is present and no response is received in response to the first alert.

Claims

1. A child car seat, comprising:

a base configured to couple to a vehicle seat;

a seat configured to couple to the base; and

a sensor device mounted to one of the base or the seat, the sensor device including a sensor that outputs a measurement signal indicating whether a child is present in the seat, a processor configured to receive the measurement signal and to determine, based on the measurement signal, whether a child is present in the seat, and a communication circuit controlled by the processor, the communication circuit transmitting a proximity signal in response to the processor determining that a child is present in the seat, the proximity signal being configured for reception by a first mobile device;

wherein the proximity signal causes a first alert to be communicated to a user of a first mobile device in response to the first mobile device exceeding a range from the sensor device; and

wherein a second alert is communicated to the user of a second mobile device if, after a threshold amount of time, the measurement signal continues to indicate that a child is present in the seat and no response is received by the sensor device in response to the first alert.

2. The child car seat of claim 1, wherein a third alert is communicated to an emergency service if, after a second threshold amount of time, the measurement signal continues to indicate that a child is present in the seat and no response is received by the sensor device in response to either the first alert or the second alert.

3. The child car seat of claim 1, wherein the sensor device is mounted to the base.

4. The child car seat of claim 1, wherein the seat comprises a harness having a chest clip, the sensor device being housed in the chest clip.

5. The child car seat of claim 4, wherein the chest clip comprises a tongue and a buckle, the sensor device being housed within a housing of the tongue.

6. The child car seat of claim 1, further comprising an indicator on at least one of the base and the seat, the indicator being detectable by the first mobile device, wherein detection of the indicator causes the first mobile device to obtain software that provides for linking the first mobile device to the sensor device.

7. The child car seat of claim 6, wherein linking the first mobile device to the sensor device provides for the first mobile device to receive safety information from a manufacturer of the car seat.

8. The child car seat of claim 1, wherein the sensor device is programmed to transmit an alert to a vehicle alarm system to generate a vehicle alarm.

9. The child car seat of claim 1, wherein the sensor device is configured to receive an environmental measurement and reduce the threshold amount of time in response to the environmental measurement exceeding a maximum value.

10. The child car seat of claim 9, wherein the environmental measurement is at least one of a humidity measurement and a temperature measurement.

11. The child car seat of claim 1, wherein the communication circuit is configured to communicate based on a wireless communication standard.

12. The child car seat of claim 11, wherein the wireless communication standard is based on at least one of a BTLE standard, an IEEE 802.15.1 standard, and an IEEE 802.15.4 standard.

13. A method for child car seat proximity detection executing on a specifically programmed processor coupled to the child car seat, comprising:

generating a proximity indication representative of a proximity of a first mobile device to the child car seat;

determining, based on the proximity indication, that the first mobile device has exceeded a threshold range from the child car seat;

generating a first abandonment alert indicating that the first mobile device has exceeded the threshold range from the child car seat;

communicating the first abandonment alert to the first mobile device;

determining that a first threshold amount of time, during which the first mobile device continues to exceed the threshold range from the child car seat, has passed without a response from the first mobile device; and

responding to a determination that the first threshold amount of time, during which the first mobile device continues to exceed the threshold range from the child car seat, has passed without a response from the first mobile device by communicating a second abandonment alert to a second mobile device.

14. The method of claim 13, further comprising determining that a second threshold amount of time, during which the first mobile device continues to exceed the threshold range from the child car seat, has passed without a response from either the first mobile device or the second mobile device;

and responding to a determination that the second threshold amount of time, during which the first mobile device continues to exceed the threshold range from the child car seat, has passed without a response from either the first mobile device or the second mobile device by communicating a third abandonment alert to an emergency service.

15. The method of claim 13, further comprising responding to a determination that the first threshold amount of time, during which the first mobile device continues to exceed the threshold range from the child car seat, has passed without a response from the first mobile device by generating an alert to a vehicle alarm system to generate a vehicle alarm.

16. The method of claim 13, wherein the proximity indication includes a received signal strength indicator (RSSI).

17. The method of claim 13, further comprising:

generating an environmental measurement representative of an environmental condition via an environmental sensor;

determining that the environmental measurement exceeds a maximum environmental measurement safety threshold; and

responding to a determination that the environmental measurement exceeds the maximum environmental measurement safety threshold by reducing the first threshold amount of time.

18. The method of claim 17, wherein the environmental measurement is at least one of a humidity measurement and a temperature measurement.

19. A system for preventing abandonment of a child in a vehicle car seat, comprising:

a car seat having a harness with a chest clip housing a sensor device, the sensor device being configured to detect the presence of a child in the car seat; and

a mobile device in communication with the sensor device;

wherein the sensor device responds to detecting the presence of a child in the car seat by transmitting a proximity signal to the mobile device; and

wherein the mobile device generates, based on the proximity signal, a first alert when the mobile device exceeds a first range of the sensor device and generates, based on the proximity signal, a second alert when the mobile device exceeds a second range of the sensor device.

20. The system of claim 19, wherein the mobile device generates the first alert and the second alert based on a signal strength of the proximity signal.
