| 20110040189 | COLLAPSED MODE OPERABLE CMUT INCLUDING CONTOURED SUBSTRATE - A capacitive ultrasound transducer capable of operation in collapsed mode either with a reduced bias voltage, or with no bias voltage, is provided. The transducer includes a substrate that is contoured so that a middle region of the flexible membrane is collapsed against the substrate in the absence of a bias voltage. A non-collapsible gap may exists between the substrate and peripheral regions of the flexible membrane. The contour of the substrate may be such as to strain the flexible membrane past the point of collapse, or to mechanically interfere with the flexible membrane. The substrate may include a further membrane disposed beneath the flexible membrane, the further membrane being contoured so that the flexible membrane is collapsed against it. The substrate may a support disposed beneath the further membrane to deflect a corresponding portion of the further membrane upward toward the flexible membrane. The support may be a post. The transducer may be operated in collapse mode with an improved efficiency (k | 02-17-2011 |

| 20110280639 | CURVED PRE-FUSER TRANSPORT TO ENABLE LARGER SHEETS THROUGH A XEROGRAPHIC PRINT ENGINE - A media transport that will fit between a xerographic transfer station and a fuser station is provided by this invention. The purpose of this media transport is to increase the distance that media with an unfused image will travel from transfer to fusing stations thus permitting longer media to be used in the xerographic system without the risk of disturbing the unfused image. A vacuum is positioned internally of the transport that will provide a vacuum force to hold a media sheet to belts that are guided by the top surface of the media transport. The media transport has a configuration with an arced top surface where the arc length of the top surface exceeds the overall width of the transport. | 11-17-2011 |

| 20110148026 | SYSTEM FOR GUIDING MEDIA IN AN IMAGING APPARATUS - A guiding system for diverting media from an input media path to an output media path in an imaging system eliminates marking and curling of media. The system employs a drive roll, an idling belt carried on one or more idler rolls, and a release roll. The idling belt presses media onto the drive roll, eliminating the relative motion between media and the drive roll and hence avoiding marking. The penetration of the release roll into the drive roll controls curling of media. | 06-23-2011 |
