Abstract: Methods and devices for aligning a media sheet in a media feed path of an image forming device. One embodiment includes a drive shaft with skew correction rollers spaced apart on the drive shaft. The media sheet contacts a first skew correction roller and then contacts a second skew correction roller. The drive shaft is then rotated, driving the second skew correction roller and aligning the media sheet to the media feed path.

Abstract: A printing system for duplex printing of a banner media is disclosed. The printing system includes a drive roll, a pair of nipping rolls abuttingly coupled to the drive roll forming a first nip and a second nip with the drive roll, a media path including a printing region and a duplex region, and a diverter disposed in the media path and coupled to the drive roll. A first side of the banner media is printed in the printing region and exited partially from the first nip. Further, the partially exited banner media is re-fed into the duplex region and transferred to the printing region to print the second side of the banner media and exited from the second nip. The duplex region is capable of receiving the banner media from the first nip and the printing region is capable of exiting the banner media from the second nip simultaneously.

Abstract: A system and method for predicting structural failure of a wall of a fluid containment vessel, such as a hydraulic hose or other type of pressurized conduit of types used in mobile machinery, automotive, aerospace, manufacturing, and process equipment. The wall of the vessel has an innermost layer for contact with the fluid contained by the vessel, and an outermost layer parallel with the innermost layer. The system includes strain-sensing means between the innermost and outermost layers and comprising at least one conductor parallel to the innermost layer of the wall. The system and method entail sensing changes in an electrical property associated with the at least one conductor resulting from distortion of the wall of the vessel causing distortion of the at least one conductor.

Abstract: The present application is directed to methods and devices for aligning a media sheet in a media feed path of an image forming device. One embodiment includes a drive shaft with skew correction rollers spaced apart on the drive shaft. The media sheet contacts a first skew correction roller and then contacts a second skew correction roller. The drive shaft is then rotated, driving the second skew correction roller and aligning the media sheet to the media feed path.
