Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing tests on mobile devices. In one aspect, a power distribution system includes a set of mobile devices and a computer that manages the execution of a test using the set of mobile devices. The computer can include one or more data communication ports. The system can also include one or more Universal Serial Bus (USB) hubs connected to the mobile devices using USB cables. Each mobile device can be connected to one of the one or more USB hubs. The system can also include one or more USB charging hubs connected between each data communication port of the computer and at least one of the one or more USB hubs. The system can also include a power supply connected between a power source and each of the one or more USB hubs.

Abstract: The present invention relates to a sensor that uses a sensing mechanism having a combined static charge and a field effect transistor, the sensor including: a substrate; source and drain units formed on the substrate and separated from each other; a channel unit interposed between the source and drain units; a membrane separated from the channel unit, disposed on a top portion and displaced in response to an external signal; and a static charge member formed on a bottom surface of the membrane separately from the channel unit and generating an electric field.

Abstract: A spherical motor rotating in multi degrees of freedom has a reliable capability of determining positioning. The spherical motor includes a hollow spherical-shaped stator installed with a bi-level bobbin wound by coil generating a synthesized magneto-motive force on an inner surface thereof; and a rotor formed inside the stator and rotating around a shaft, wherein a slope of the shaft is adjusted by the synthesized magneto-motive force. Two or more of the bobbins are provided and installed at regular intervals along the inner surface of the stator, and the rotor includes one or more permanent magnets. The spherical motor rotating in multi degrees of freedom, formed with the above mentioned figures, can embody multi degrees of freedom by the interaction between the flowing current in the winding coil around the bobbin and the permanent magnet.

Abstract: A method for skipping advertisement broadcasting is provided. Whether or not it is advertisement broadcasting is determined using an program ID of received broadcasting contents. When it is advertisement broadcasting, the advertisement is skipped. During the advertisement broadcasting skipping, a multi tasking environment other than broadcasting viewing is provided. By skipping advertisement broadcasting during the broadcasting content recording, the recording results not including the advertisement is obtained.
