Systems and methods define a stimulation pattern for a juvenile product utilizing a mobile device that executes a mobile application that is linked to the juvenile product. The method comprises the step of recognizing, by the mobile device when executing the mobile app, the user-defined stimulation pattern for the juvenile product. The stimulation pattern can be a vibration pattern or a motion pattern, and can be detected in a number of different ways by the mobile device. The method further comprises the step of determining control signals for the actuator(s) of the juvenile product based on the user-defined stimulation pattern that is recognized by the mobile device. The method further comprises the step of, in response to receiving a command to execute the user-defined stimulation pattern, controlling the actuator(s) of the juvenile product based on the stored control signals for the user-defined stimulation pattern.

A pivotal joint structure is connected to a front leg and a bottom pipe of a stroller. The pivotal joint structure includes a connecting component disposed in the bottom pipe. A first end of the connecting component is fixedly connected to the front leg. The pivotal joint structure further includes an inner fixing component and an outer fixing component, which are disposed in the bottom pipe and connected to the bottom pipe. The connecting component is disposed between the inner fixing component and the outer fixing component, and the inner fixing component and the outer fixing component are rotatable around the connecting component. The front leg can be further folded relative to the bottom pipe by the pivotal joint structure. Therefore, the occupied space of the folded stroller can be further reduced, so as to facilitate carrying and storage when not in use.

The present invention is a modular stroller platform for carrying multiple small children. The invention enables secure mounting of three seats or carriers in a compact arrangement, giving each child sufficient space without making the stroller unnecessarily difficult to move. Because of its modular design, other accessories, including a wagon body, may be mounted in place of the seats.
