US Patent 8256793 Multi-functional stroller and associated method

A multifunctional stroller includes a frame, a user interface, a light assembly, a music playback device, and a timer-actuated switch electrically coupled directly to a power source. Sensors determine a real-time temperature at the multifunctional stroller and are coupled directly to the timer-actuated switch. Such sensors generate and transmit first, second and third input signals to the timer-actuated switch upon detecting first, second and third triggering events respectively. The user interface generates and transmits first and second control signals to the light assembly and the timer-actuated switch respectively upon receiving corresponding user inputs respectively. The timer-actuated switch is toggled to an open position upon receiving at least one of the first, second and third input signals within a first time period after receiving the second control signal so that power is transmitted to the music playback device for a second time period.
