Title: Method and system for constructing and displaying three-dimensional images
Inventor: CHAN THOMAS K C
IPC: G06T15/20
Filed: 1995-06-23
Granted: 1999-09-14
Abstract: A three-dimensional ultrasound imaging system includes an ultrasound probe to direct ultrasound waves and to receive reflected ultrasound waves from a target volume of a subject under examination. The ultrasound probe is swept over the target volume and the reflected ultrasound waves are conveyed to a computer wherein successive two-dimensional images of the target volume are reconstructed fo form a three-dimensional image of the target volume. The three-dimensional image is displayed on the monitor of the computer. A user interface allows a user to manipulate the displayed image. Specifically, the entire displayed image may be rotated about an arbitrary axis, a surface of the displayed image may be translated to provide different cross-sectional views of the image and a selected surface of the displayed image may be rotated about an arbitrary axis. All of these manipulations can be achieved via a single graphical input device such as a mouse connected to the computer.

The first and second walls have differential thicknesses so as to accommodate the draft angle of the ring.  A plurality of fins are formed integrally on the exterior of the gasket for creating an interference fit with the end grooves.          In the preferred embodiment, the first wall is substantially thicker than the second wall and the fins exterior to the first wall are thicker than the fins on the second wall.  Also, the thicknesses of the first and second walls are preferably tapered so as to define an interior cavity having a draft angle equal to that of the ring.

Abstract: An improved method and apparatus for determining the amount of turn coordination gain in an aircraft yaw damper during a turn maneuver is disclosed. The yaw damper includes inputs from the inertial reference units of the aircraft and also from the flight management computer of the aircraft. The flight management computer provides to the yaw damper a signal indicative of the position of the flaps of the aircraft. The yaw damper includes a turn coordination gain box that receives the flap position signal and outputs a turn coordination gain value, dependent upon the flap position. Generally, the turn coordination gain value increases as the flap position is more extended. The precise turn coordination gain value for each flap position is dependent upon the particular aerodynamic characteristics of the aircraft.

Title: Metal halide high pressure discharge lamp
Inventor: GENZ ANDREAS
IPC: H01J61/82
Filed: 1997-10-20
Granted: 2005-05-17
Abstract: A metal-halide high-pressure discharge lamp (1) with a discharge vessel (2) and two electrodes (4, 5) has inside discharge vessel (2) an ionizable filling, which contains yttrium (Y) in addition to inert gas, mercury, halogen, thallium (T1), hafnium (Hf), whereby hafnium can be replaced wholly or partially by zirconium (Zr), dysprosium (Dy) and/or gadolinium (Gd) as well as, optionally, cesium (Cs). Preferably, the previously conventional quantity of the rare-earth metal is partially replaced by a molar equivalent quantity of yttrium. With this filling system, a relatively small tendency toward devitrification is obtained even with high specific arc powers of more than 120 W per mm of arc length or with high wall loads.  Thus, the filling quantity of cesium can be clearly reduced relative to a comparable filling without yttrium, whereby an increase in the light flux and particularly in the brightness can be achieved.

Abstract: A hilling spade according to the present invention has a pair of moldboards or wings defining a plowing angle having a pointed forward end. Each wing has a central planar surface, a cutting edge, and a lower curved surface between the cutting edge and the central planar surface. The lower curved surface has a curvature oriented vertically inwardly relative to the plowing angle. Each wing also has an upper curved surface having a curvature oriented vertically outwardly relative to the plowing angle. When the hilling spade is used for hilling ridges along rows of plants, the lower curved surfaces are usable for lapping lower portions of the ridges for compacting the lower portions and for reducing erosion of these ridges. The upper curved surfaces are usable for pushing soil over the ridges and under the foliage of the plants on those ridges without damaging the foliage.

Title: System and method for manipulating data fields in a call structure for synchronizing billing information and retaining original calling party information
Inventor: MALIK DALE W
IPC: H04Q3/00
Filed: 1998-08-05
Granted: 2002-01-08
Abstract: A system and method for synchronizing billing information and maintaining original calling party information when providing an enhanced communication service. A communication is received from a first network element and directed to a feature access code. In connection with the communication, a string of data is received containing call information for correction of parameters of a call structure. In response to receiving the communication directed to the feature access code, the string of data is manipulated within the parameters of the call structure based on instructions provided by a database, whereby original calling party information located in the call structure is retained and billing information is ultimately synchronized with an associated subscriber. Advantageously, the tasks of synchronizing billing information and maintaining call origination are accomplished by providing a standard format for processing long strings of data representing information on how a call is to be configured and by reformatting the data fields based on this information so that the final call structure resembles that of the original call structure.

Abstract: Après un séchage par de l'air traversant, on soumet à un calandrage des bandes basse densité constituées de fibres de pâte thermomécanique chimique blanchies et de résine incorporée pour améliorer la résistance au déchirement à l'état humide, ce calandrage ayant pour effet d'augmenter, d'une manière considérable, la densité et de diminuer l'épaisseur. Lorsque ces bandes sont mouillées, elles reviennent sensiblement à leur épaisseur initiale et à leur densité initiale, pour retrouver leur aptitude initiale à absorber les fluides. Par conséquent, ces bandes sont très minces quand elles sont sèches et épaisses quand elles sont mouillées. Elles peuvent être utilisées dans une variété d'applications, en particulier pour des serviettes en papier, des essuie-mains et des éléments absorbants dans les articles pour bébés et les articles d'hygiène personnelle.
