  • Publication number: 20170284254
    Abstract: A drip-irrigation catalytic reduction exhaust pipe includes an exhaust pipe having a pipe wall in which a plurality of first apertures is formed and a plurality of direct-through ceramic filters arranged in the exhaust pipe in an axial direction from an exhaust gas inlet opening toward the exhaust gas outlet opening, or alternatively, a wall-flow filter being arranged at a location that is closest to the exhaust gas outlet opening. A flow guide tube is arranged outside the exhaust pipe and is connected to a container and includes a plurality of second apertures. The second apertures respectively correspond to the first apertures. An electromagnetic valve controls passage of urea liquid contained in the container through the second apertures and the first apertures to drip into the exhaust pipe and absorbed by a ceramic fiber material for penetration into pores of the direct-through ceramic filters and the wall-flow filter.

  • Patent number: 9715863
    Abstract: Techniques for scale factor based on viewing distance are described. In at least some embodiments, a viewing distance refers to a distance at which a user typically views and/or is viewing a display device. For instance, different displays can be used in different ways and for different purposes, and thus may have different viewing distances. Techniques discussed herein consider the estimated viewing distance of a particular display in determining a scale factor to be applied to visual elements (e.g., graphics) for output via the particular display. A scale factor, for instance, can specify that visual elements are to zoomed-out or zoomed-in prior to be displayed. As detailed herein, this enables a consistent viewing experience to be maintained across different devices with different display sizes and different viewing distances.
