  • Patent number: 8266754
    Abstract: An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

  • Publication number: 20070009991
    Abstract: A recombinant nucleic acid is provided having an avian promoter. One embodiment of the present invention contemplates the use of a gut-specific promoter, wherein a promoter can be the chicken intestinal fatty acid binding protein promoter region. A method for making a transgenic bird is also disclosed by transfecting a bird with a vector comprising a recombinant nucleic acid comprising a chicken intestinal fatty acid binding protein promoter region operably linked to a heterologous nucleic acid expressing a desired polypeptide to be expressed in the gut tissue of an avian.
