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 stroller frame has a push-pull function consisting of a lower supporting frame and an upper frame connected through a frame joint. The lower supporting frame comprises a front leg connected to a front wheel set and a rear leg connected to a rear wheel set. The lower portion of the front leg is pivotally attached to a pull rod assembly located at the front of the stroller frame. In addition, a push rod assembly is connected to the lower supporting frame and extends diagonally toward the rear of the stroller frame to allow the user to push the stroller frame in a raised position while walking, which facilitates pulling or pushing the stroller frame as desired while also allowing interaction with the child riding on the upper frame. The stroller frame is characterized by its ease of use and versatile functionality.
