Patent ID: 7407178

Claim:
An apparatus comprising: a stroller having at least a wheel for rolling along a surface and for supporting the stroller during rolling thereof; a generator mounted to the stroller and rotationally coupled to the at least a wheel; a shade rotationally coupled to a frame of the stroller; a sensor for sensing a relative orientation between a light source and the stroller, the sensor for providing a sensor signal in dependence upon the sensed orientation; a controller for receiving the sensor signal from the sensor and for providing a control signal in dependence upon the sensor signal; and, an actuator disposed for changing an angle of the shade relative to the frame in response to the control signal, the actuator electrically coupled to the generator, wherein when the stroller is moved relative to a ground surface in a standard fashion, the generator is actuated thereby producing an electric potential, and wherein the angle of the shade is changed to compensate for movement of the light source relative to the stroller resulting from the movement of the stroller relative to the pound surface in the standard fashion.
