20090284431 | INTEGRATED ELECTRONICS MATCHING CIRCUIT AT AN ANTENNA FEED POINT FOR ESTABLISHING WIDE BANDWIDTH, LOW VSWR OPERATION, AND METHOD OF DESIGN - An integrated electronics matching circuit is placed directly at the feed points of an antenna to match a transmission line to the impedance of the antenna that results in preserving the originally-designed wide bandwidth of the antenna, which in one embodiment is 10:1. A methodology is provided for the design of the integrated electronics matching circuit that marries the output of an antenna modeling tool with an integrated circuit design tool, in which the S parameter outputs of the antenna modeling tool for the antenna ports are coupled to the corresponding ports of the integrated circuit designed by the integrated circuit design tool. | 11-19-2009 |

20090121619 | OLED Having A Charge Transport Enhancement Layer - Charge transport enhancement layers and structures are provided that may improve the performance of organic devices, specifically organic light emitting devices. A charge transport enhancement layer may include a layer or an inorganic material, metal oxide, halide, and/or alkali disposed between two organic layers, and separated from the cathode by an intervening organic layer. One or more CTELs may be used, such as in an alternating stack of organic and CTEL layers. Surprisingly, it has been found that the use of one or more CTELs arranged in a stack with intervening organic layers may improve the performance of the device even where the layer is not directly adjacent to the cathode. | 05-14-2009 |

20100059297 | TRACK SUSPENSION - A flexible, non-resilient strap of the tandem wheel suspension interconnects the vehicle frame and one of the rocker arms of an endless track vehicle, limiting the motion of the rocker arm in the direction of the terrain but permitting freedom of motion in an upward direction away from the terrain. The rocker arms share a support axle mounted to the vehicle frame, and each rocker arm is independently movable about the support axle. A shock-absorbing element, located in the vicinity of the strap, is preferably similarly attached between the frame and the same rocker arm to dampen the motion of the rocker arm in the direction of the terrain while permitting freedom of motion in an upward direction away from the terrain. In one embodiment, a small idler roller is positioned slightly above the endless track at a location between the two tandem wheel suspensions supporting the endless track. | 03-11-2010 |

20150231313 | MEDICAL TUBE CLEARANCE DEVICE - A device for clearing obstructions from a medical tube includes an enclosure having an interior and an exterior, the enclosure comprising a distal opening for providing access to the interior of the enclosure. The device further includes a spool provided within the enclosure that is rotatable about an axis and an elongated guide member coupled to the spool such that rotation of the spool causes the guide member to wind or unwind about the spool. The device further includes a drive mechanism that is operable to rotate the spool within the enclosure without compromising a sterile field within the enclosure. | 08-20-2015 |

20090087330 | FLUID PUMP - A pump is disclosed, having a pumping chamber in the rotor. The rotor is rotatable between first, second, third and fourth positions. When the rotor is in the first position, an inlet cam assembly displaces a piston to draw fluid into the pumping chamber via a first housing inlet. When the rotor is in the second position, an outlet cam assembly displaces the piston to expel fluid out of the pumping chamber via a first housing outlet. When the rotor is in the third position, the inlet cam lobe assembly displaces the piston to draw fluid into the pumping chamber via a second housing inlet. When the rotor is in the fourth position, the outlet cam assembly displaces the piston to expel fluid out of the pumping chamber via a second housing outlet. A method of pumping fluid is also disclosed. | 04-02-2009 |
