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.

Abstract: A stroller configured to support a child is provided that includes a frame, a plurality of wheels supporting the frame, a forward facing seat supported by the frame, a rearward facing seat supported by the frame, a seat back positioned to support a child reclining in the forward facing seat, and a platform positioned rearward of the forward facing seat to support a child standing on the platform.
