| 20100112896 | Corner Booster For Toy Vehicle Track Set - A corner booster for accelerating toy vehicles includes an entrance to which a toy vehicle enters the booster, and an exit from which the toy vehicle exits the booster. The entrance and exit are orientated so that the toy vehicle turns when traveling from the entrance to the exit. The corner booster further includes a booster member for applying a force to the toy vehicle. The force applied by the booster member increases the speed of the toy vehicle as the toy vehicle travels from the entrance to the exit. The corner booster includes a cocking mechanism that cocks the booster member with preloaded mechanical energy. The preloaded mechanical energy is used to move the booster member to apply the boosting force to the toy vehicle. | 05-06-2010 |

| 20110019844 | MULTI-DIRECTIONAL SOUND EMISSION SYSTEM - A multi-directional sound emission system comprises a speaker body and sound emission devices coupled to both ends of the speaker body. The sound emission devices each include a sound emission means for directionally emitting sound towards multiple directions. The sound emission means includes a plurality of hollow mechanical sound conducting elements. Each hollow mechanical sound conducting element has an inner opening end and an exterior opening end opposite to the inner opening end. The exterior opening ends of the sound conducting elements are directed towards desired multiple directions, respectively. The sound emission means is configured for receiving sound signals from the speaker body and emitting sound along the desired multiple directions through the sound conducting elements. | 01-27-2011 |
| 20110019853 | MULTI-DIRECTIONAL SOUND EMISSION MEANS AND MULTI-DIRECTIONAL SOUND EMISSION SYSTEM - A multi-directional sound emission means and a system having same are disclosed. The system comprises a speaker body and sound emission devices coupled to both ends of the speaker body. The sound emission devices each include a sound emission means for directionally emitting sound towards multiple directions. The sound emission means includes a base, a loudspeaker disposed on the base, and a plurality of hollow mechanical sound conducting elements. The loudspeaker has an opening where the sound is emitted. Each hollow mechanical sound conducting element has an inner opening end and an exterior opening end opposite to the inner opening end. The exterior opening ends are directed towards desired multiple directions, respectively. The inner opening ends are in sound communication with the opening of the loudspeaker such that sound from the loudspeaker is emitted along the desired multiple directions through the sound conducting elements. | 01-27-2011 |

| 20100315958 | METHOD FOR NON-COOPERATIVE MEASUREMENT OF NETWORK DATA-PATH QUALITY - A method and apparatus for measuring network path quality in a non-cooperative manner, which involves sending a probe consisting of a plurality of probe data packets to a remote node and receiving a response consisting of at least one response data packet therefrom. Both the probe and response data packets carry application messages and are exchanged according to normal transmission mechanisms, so that the method can void the reliability problem suffered by methods using non-data probes. The response data packets, at the same time, provide sufficient information for obtaining a rich set of data-path quality metrics in an efficient way. | 12-16-2010 |
