20080249535 | Vaginal Spring Loaded Delineator - A gynecological instrument for delineating the formix of the vagina during laparoscopic surgeries having a spring, which proximal end is affixed to a solid ring and the distal end is affixed to a base. The extension of the base can be inserted into the head of the Valtchev® Uterine Mobilizer and locked in place. The solid ring can be tilted in any direction, and can come closer to the base, allowing automatic adjustment for the angles of the formix of the vagina and the cervical length. An elastic plastic ring is provided, for placing on the solid ring, in order to protect the ring and instrument which is used to open the vagina laparoscopically. | 10-09-2008 |
20100180422 | Vaginal delineating device - A gynaecological instrument for delineating the fornix of the vagina during laparoscopic surgeries having a spring, which proximal end is affixed to a solid ring and the distal end is affixed to a base. The extension of the base can be inserted into the head of the Valtchev® Uterine Mobilizer and locked in place. The solid ring can be tilted in any direction, and can come closer to the base, allowing automatic adjustment for the angles of the fornix of the vagina and the cervical length. | 07-22-2010 |

20140032736 | Lattice Based Traffic Measurement - A lattice of interconnected concepts is constructed from flow entries. Each concept describes a subset of flows and a subset of the flow attributes. Based on user queries, the lattice is used to build disjoint sets of flows referred to as flowsets. Each user query specifies one or more of the flow attributes to be measured. Each flowset includes one or more of the flows to thereby enable sharing of the hardware counters among the flows. One hardware counter is then assigned to each flowset. | 01-30-2014 |

20080222618 | Methods for User Interface Generation and Application Modification - A method of generating a user interface for presentation to a user. The method comprises executing a first application computer program to provide a user interface, executing agent computer program code to interrogate and modify said user interface during execution of said first application computer program, and presenting said modified user interface. The first application computer program may be run on a server, while the modified user interface may be presented to a user at a client connected to said server. | 09-11-2008 |
20100064208 | METHOD AND APPARATUS FOR USER INTERFACE MODIFICATION - A method and apparatus for modifying a user interface. The method comprises receiving user interface data at a client from a first server, receiving modification computer program code at said client, and executing said modification computer program code at said client to modify said user interface data to generate modified user interface data. The modification computer program code can be received from said first server or from a further server. | 03-11-2010 |
20130283292 | Method and Apparatus for Composite User Interface Generation - A method for directing messages between a composite user interface and at least one source application. A message is to be directed to a predetermined set of services, each service executes a command specified by the message and the message comprises details of the predetermined set of services. Each service in the predetermined set of services uses said details to determine whether the message should be sent to another service, and if it is determined that the message should be sent to another service transmits the message to an appropriate service. | 10-24-2013 |

20140029781 | Spherical Sound Source for Acoustic Measurements - Spherical sound source comprising two coaxial loudspeakers and two mid-high frequency compression drivers. Low frequencies are radiated by the two low-frequency sections of the coaxial loudspeakers. Mid-frequencies 500 Hz-2000 Hz are radiated by the two mid-high frequency compression drivers. High-frequencies 2 kHz-10 kHz are radiated in the horizontal plane by the same mid-high frequency arrangement together with two compression drivers of the coaxial loudspeakers in each vertical direction. Identical drivers form three pairs. One driver from each pair is enclosed in one of two symmetrically opposite half-embodiments, spaced at predetermined distance to create a common radially expanding horn for the two mid-high frequency compression drivers. All loudspeakers share the same vertical axis of rotational symmetry. The two half-embodiments might be used as separate standalone spherically radiating sources when installed on hard surface. The invention is appropriate for sine-swept acoustic measurements and sound isolation measurements in high sound transmission class buildings. | 01-30-2014 |

20090172651 | CREATING AND USING DELTAS TO MODIFY EXISTING COMPUTER CODE - Aspects of the subject matter described herein relate to creating and using deltas to modify existing computer code. In aspects, computer code may be translated into a higher level language to make it easier for a software developer to modify the computer code. The translated computer code may be presented by an editing tool that presents a user interface that allows changes to be made to the translated computer code. A delta engine may then determine a delta that indicates the changes to perform on the existing computer code to create computer code that would result from compiling the translated computer code as changed via the editing tool. Later, this delta may be used to change the existing computer code after it has been loaded to add or change debugging hooks or other features of the computer code. | 07-02-2009 |

20090029845 | FAU-structural-type supported zeolite membranes, their process for preparation and their applications - The invention relates to a FAU-type zeolite membrane that comprises a FAU-type zeolite crystal layer incorporated in the surface porosity of at least one selected face of a porous substrate, in which the ratio between the thickness of said zeolite layer incorporated in the surface porosity of said selected face of the substrate and the total thickness of said zeolite layer is at least 70%. It also relates to processes for preparation and application of these membranes. | 01-29-2009 |
20090036294 | CATALYST IN THE FORM OF GRAINS COMPRISING AN ACIDIC POROUS CORE SURROUNDED BY A UNIFORM OUTER LAYER - The invention relates to a catalyst that comes in the form of grains, each grain consisting of a core covered by at least one external layer, the core consisting of an acidic porous solid and having a size of between 0.1 micron and 0.4 millimeter, in which the external layer has a uniform thickness with a uniformity criterion C, which is less than 0.30, whereby said uniformity criterion C is defined as being equal to an average, on a number N of catalyst grain samples, of the ratio of the difference between the maximum thickness, Ei | 02-05-2009 |
