Child abandonment monitor
First Claim
1. A child car seat, comprising:
- a base configured to couple to a vehicle seat;
a seat configured to couple to the base;
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 the 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 the child is present in the seat, the proximity signal being configured for reception by a first mobile device; and
an environmental sensor mounted to one of the base or the seat, the environmental sensor generating an environmental measurement representative of an environmental condition;
wherein the proximity signal causes a first alert to be communicated to a user of the first mobile device in response to the first mobile device exceeding a range from the sensor device;
wherein a second alert is communicated to a user of a second mobile device if, after a first threshold amount of time, the measurement signal continues to indicate that the child is present in the seat and no response is received by the sensor device in response to the first alert;
wherein the seat comprises a harness having a chest clip with a tongue and a buckle, the sensor device being housed within a housing of the tongue;
wherein the processor is configured to receive the environmental measurement and to determine whether the environmental measurement exceeds a maximum environmental measurement safety threshold; and
wherein the processor is configured to respond to a determination that the environmental measurement exceeds the maximum environmental measurement safety threshold by reducing the first threshold amount of time.

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.

9. 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 the 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 the 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 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 in response to an absence of a response to the first alert from the first mobile device for a threshold amount of time; and 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. - View Dependent Claims (10)

11. 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, the child car seat including a harness having a chest clip with a tongue and a buckle; sensing, with a sensor device, whether a child is present in the child car seat, the sensor device being housed within a housing of the tongue; 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; 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; 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. - View Dependent Claims (12, 13, 14, 15)
