  • Patent number: 8939814
    Abstract: A smart toy driving system for a mobile terminal connected to the mobile terminal such that a reaction generated by an interaction between a certain character and a mobile terminal user upon the execution of an application installed in the mobile terminal is expressed in a motion of the character. The smart toy driving system includes a mobile terminal provided with an audio signal generating part which generates an audio signal having a predetermined pattern and then outputs it through a terminal part for outputting a sound; and a character which is detachably coupled to the terminal part of the mobile terminal so as to receive the audio signal, wherein the character comprises a signal converting part which converts the received audio signal into a driving signal preset according to a predetermined patterned waveform, and a mechanism part which takes a predetermined mechanical action according to the converted driving signal.

  • Patent number: 8878546
    Abstract: An apparatus for quickly determining a fault in an electric power system includes a current transformer, a current determination unit and a fault determination unit. The current transformer detects current supplied to the electric power system and outputs a current detection voltage. The current determination unit respectively compares the current detection voltage, the first-order differential voltage of the current detection voltage and the second-order differential voltage of the current detection voltage with predetermined first, second and third reference voltages. The fault determination unit determines whether a fault occurs based on the compared result of the current determination unit and generates a trip signal when it is determined that the fault has occurred.
