20120170820 | METHODS AND APPARATUS FOR COMPARING 3D AND 2D IMAGE DATA - In a method or apparatus of comparing two image data sets from medical imaging data of a subject, a first, three-dimensional image data set of the subject is obtained. A second, two-dimensional image data set of the subject is also obtained. The first data set is registered with the second data set. Data from the first, three-dimensional image data set is processed to determine a voxel in the first data set which corresponds to a given pixel in the second, two-dimensional image data set. | 07-05-2012 |
20120177258 | METHODS AND APPARATUS FOR GENERATING A MODIFIED INTENSITY PROJECTION IMAGE - In a method or apparatus for generating, from medical image data of a subject from a functional imaging modality, a modified intensity projection image for display. An intensity projection image data set is obtained from the image data. A segmentation for the image data is obtained. Based on information from the segmentation, a modified display property is calculated for at least one voxel of the intensity projection image data set. | 07-12-2012 |

20080247620 | Apparatus and Method for Augmenting Sight - A method of augmenting sight in an individual. The method comprises obtaining an image of a scene using a camera carried by the individual; transmitting the obtained image to a processor carried by the individual; selecting an image modification to be applied to the image by the processor; operating upon the image to create a modified image using either analog or digital imaging techniques, and displaying the modified image on a display device worn by the individual. The invention also relates to an apparatus augmenting sight in an individual. The apparatus comprises a camera, carried by the individual, for obtaining an image of a scene viewed by the individual; a display carried by the individual; an image modification input device carried by the individual; and a processor, carried by the individual. The processor modifies the image and displays the modified image on the display carried by the individual. | 10-09-2008 |

20130067899 | HYDROSTATIC TORQUE CONVERTER AND TORQUE AMPLIFIER - An example includes a hydraulically controllable coupling to couple a rotating input and to an output to rotate, or to decouple the input and the output, with coupling and decoupling modes selected by switching a hydraulic device such as a vane pump between a pumping mode and a mode in which it does not pump. In an example, the system cooperates with a transmission to increase the number of possible gear ratios in some examples. | 03-21-2013 |

20140328709 | HYDRAULIC MACHINE WITH VANE RETAINING MECHANISM - A hydraulic pump or motor includes a body having a chamber and a rotor rotatably mounted within the chamber. The chamber and rotor are shaped to define one or more rise regions, fall regions, major dwell regions and minor dwell regions between walls of the chamber and the rotor. The rotor has a plurality of slots and vanes located in each slot. Each vane is movable between a retracted position and an extended position. In the retracted position, the vanes are unable to work the hydraulic fluid introduced into the chamber whereas they are able to work the hydraulic fluid introduced into the chamber in the extended position. A vane retaining member that is selectively actuable enables the vanes to be retained in the retracted position. | 11-06-2014 |

20080310988 | Vane Pump - A vane pump for pumping hydraulic fluid wherein fluid at a pressure intermediate the inlet pressure and the outlet pressure of the pump is supplied to under vane passages of the vanes located in and passing through the rise region of the pump. This assists in preventing damage to the vanes caused by driving the vanes through the protective coating of oil on the wall of the pump chamber when the vanes are travelling through an inlet region of the pump. | 12-18-2008 |
20090280021 | HYDRAULIC MACHINE - A hydraulic pump or motor includes a body having a chamber and a rotor rotatably mounted within the chamber.

20100028181 | VANE PUMP FOR PUMPING HYDRAULIC FLUID - A vane pump of the intravane type for pumping hydraulic fluid, wherein each vane of the pump has two intravanes and that pressurized oil is provided to one or both intravane regions when the vane is in a rise region of the pump. The pump is operated such that the pressurized oil is provided to both undervane regions when the pump is running at low speed but the pressurized oil is provided to only one of the undervane regions when of the pump is running at high speed. | 02-04-2010 |

20120039020 | Switch panel - There is disclosed an improved switch panel (SP), e.g. for use in automotive vehicles or electronic/electrical apparatus such as white goods or keypads. Modern switch panels, particularly in cars/automobiles, are provided with an increasing number of electronic controls and equipment. A problem has therefore arisen in that a driver/passenger/user can easily become confused when presented with an array of control switches. The invention therefore provides a switch panel (SP) having a panel member (P) and at least one switch member (S), wherein the panel member (P) has a first appearance when front lit, and at least one second appearance when at least a portion thereof is back lit. The back lighting is provided by illumination means controlled by the at least one switch member (S). The at least one switch member (S) is provided on a reverse (rear) side ( | 02-16-2012 |
