  • Publication number: 20180296046
    Abstract: A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

  • Patent number: 9529438
    Abstract: Print objects (38) are captured. In the process of capturing each of the print objects (38) a user input gesture (34) over a region of a document (18) being rendered on a display (16) in accordance with a structured object specification (20) of the document (18) is received; an element of the structured object specification (20) being rendered within an active area of the user input gesture (34) on the display (16) is identified; the user input gesture (34) is interpreted as a print content designation command; and the print object (38) is derived from the structured object specification (20) in accordance with the identified element of the structured object specification (20) and the print content designation command. A print layout (32) of the print objects (38) on one or more pages (50) is determined. The print layout (32) is outputted.
