20150352380 | Descent Rescue Device with Double Brake and Back and Forth Controlled - A descent rescue device with double brake and back and forth controlled comprising an outer shell and a tyra mechanism, a double braking mechanism, and a line-guiding mechanism, the tyra mechanism is connected to the double braking mechanism and moving together, while the outer braking component in the state of no pressure or the biggest pressure, the inner braking component is to be in the state of riding the brake and producing damp in order to tighten and lock the steel wire rope wrapping around it. While the outer braking component in the state of half clutch, the lock of the steel wire rope by the inner braking component and the brake hub are in friction state, then the steel wire rope would be leaded from the line-guiding mechanism easily because of the frictional resistance, so as to achieve the purpose of slowing down from the high building. | 12-10-2015 |

20150352874 | MEDIA ALIGNMENT - A media alignment method includes printing a calibration pattern on a media in a print one by a printhead including forming a first corner identification marker at a first corner of a reference edge of the media, a second corner identification marker at a second corner of the reference edge, and a linear identification marker. The method also includes capturing the calibration pattern by an image capturing unit. The method also includes determining a printhead axis based on the linear identification marker, determining a default printhead origin based on the printhead axis and the linear identification marker, and determining a media origin based on the printhead axis, the first corner identification marker, and the second corner identification marker. The method also includes determining an offset compensation parameter by the determination module corresponding to a distance between the default printhead origin and the media origin. | 12-10-2015 |
