  • Patent number: 8095714
    Abstract: An electronic device, includes a USB interface, a processing unit, a master-slave select triggering circuit, a controlling unit, a selection circuit and a switching circuit. The master-slave selection triggering circuit including an input port, a first output port and a second output port. The master-slave select triggering circuit is used to detect the type of external electronic devices connected to the USB interface, if the external electronic device is a master device, the first and second output port output a slave triggering signal, the controlling unit switches off the switching circuit t and the selection circuit selects the processing unit into slave mode; if the external electronic device is the slave device, the first and second output port output a master triggering signal, the controlling unit switches on the switching circuit and the selection circuit select the processing unit into master mode.

  • Patent number: 7947501
    Abstract: A method of creating a human pluripotent transgenic stem cell, wherein heterologous DNA is inserted into specific “hot-spots” in the genome where stable and high gene expression may occur, is disclosed. In one embodiment, the method comprises the steps of: (a) selecting a pluripotent stem cell line, and (b) inserting heterologous DNA at an insertion site selected from the group consisting of insertion site one and insertion site two to form a transgenic cell line. In another embodiment, the heterologous DNA is an exchange cassette and the transgenic cell line formed is a master cell line.
