A decorative lawn ornament including a rotatable carrier having a plurality of blades. At least one light-emitting device is arranged on each of the plurality of blades to emit light from the blades. A solar panel is provided to receive and collect sunlight, and a photoswitch is automatically operable between an activated state during instances of insufficient sunlight to thereby activate the light-emitting device, and a deactivated state during instances of sunlight to thereby deactivate the light-emitting device. The decorative lawn ornament is operable such that when a flow of air strikes it, the blades rotate and a decorative member rotates to control an orientation of the blades and the light emitted by the light-emitting devices.

A yo-yo has at least one sensor configured to measure a parameter related to movement of the yo-yo, a transmitter configured to transmit the measured parameter to the computing device. A server is configured to determine a trick performed with the yo-yo based on the measured parameter, and to communicate the determination to one or more computing devices of different players.

A spinning toy is housed within a handle-shaped housing and a string actuated internal spinning mechanism. The internal spinning mechanism is secured to a vertical shaft which projects from the top of the housing. Secured to the distal exterior end of the shaft is a propeller comprising a plurality of blades. An exterior end of the string projects through the housing. When the string is pulled it actuates the spinning mechanism which actuates the vertical shaft which in turn rotates the propeller.

There described a computerized yo-yo toy that uses an acceleration measuring device, a computation and control device, a communication device and entertaining devices to enhance the entertaining experience of playing with the computerized yo-yo toy. The acceleration measuring device measures the acceleration values of the computerized yo-yo toy. The computation and control device uses the measured acceleration values to generate control signals to control entertaining devices such as a light display device, an audio play device and an auxiliary device for an enhanced entertaining experience. The entertaining devices may be latched to the computerized yo-yo toy, which allows using different and new entertaining devices with the computerized yo-yo toy. The control signals are based on the measured acceleration values, the type of entertaining device latched to the computerized yo-yo and setup parameters received by the communication device from an external device, such as smartphone or tablet. The communication device may also send data from the computerized yo-yo toy to the external device, which allows the external device to analyze, store or display the data for an enhanced entertaining experience.

There described a computerized yo-yo toy that uses an acceleration measuring device, a computation and control device, a communication device and an electric clutch device to effect the motion of the computerized yo-yo toy. The acceleration measuring device measures the acceleration values of the computerized yo-yo toy. The computation and control device uses the measured acceleration values to generate control signals to the electric clutch device. The electric clutch device creates or eliminates friction with an outer case of a ball bearing, based on the control signals, to affect the motion of the computerized yo-yo toy. The communication device receives setup parameters from an external device and transmits the setup parameters to the computation and control device. The computation and control device may further generate the control signals to the electric clutch device based on the setup parameters.
