  • Patent number: 11866733
    Abstract: Methods are disclosed herein for efficiently generating human induced pluripotent stem cells (iPSC) containing a nucleic acid including a doxycycline promoter operably linked to a nucleic acid encoding Cas9. These methods include transfecting a human somatic cell with a nucleic acid molecule comprising a doxycycline promoter operably linked to a nucleic acid encoding a Cas9, and constitutive promoter operably linked to a tetracycline responsive element and inducing the somatic cell to form an iPSC, thereby producing an iPSC that can undergo CRISPR/Cas9-mediated recombination at a high efficiency. The human iPSC, or a cell differentiated therefrom, is cultured in the presence of doxycycline to induce expression of the Cas9. These cells can then be used to target in any gene of interest by introducing nucleic acids encoding sgRNAs. Induced pluripotent stem cells produced by these methods are also disclosed.

  • Patent number: 9316738
    Abstract: A mobile wireless system (10) includes a transmitter such as a satellite (18) that broadcasts wireless signals such as boundaries for specific areas to a mobile receiving device (22). Mobile receiving device (22) may include an antenna (26) and a mobile receiving device (28). A locating receiver (50) is used to generate locating signals so that a determination may be made to the location of the mobile receiving device. When the location is outside an area of interest the area of interest may be extended to provide services to the mobile device.

  • Patent number: 8750785
    Abstract: A receiving unit 28 includes a tuner circuit board 104 that receives a satellite signal. The tuner circuit board 104 demodulates and decodes the satellite signal to form a second signal. The second signal is provided to a processor board 112 that is separated from the tuner and formats the second signal to form an audio signal and a video signal. An integrated bus 100 couples the tuner circuit board 104 and the processor circuit board 112. The integrated bus 100 comprises the second signal, the audio signal and the video signal.
