Patent attributes
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.
