Abstract:
An improved Vivaldi antenna enhances the performance over a 2:1 frequency band while occupying a compact format. Taking advantage of a common FR4 material printed circuit board construction, considered features are added which improve the operating bandwidth without adding additional cost. One such embodiment operates over an approximate frequency range of 400 to 900 MHz.
Abstract:
According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes receiving a telephone number (TN) to test for its porting activity as part of a local number portability (LNP) order, accessing a LNP call tester (LCT) to determine a current local routing number (LRN) for the TN, and determining, based on the TN and current LRN, whether the porting activity is completed for the TN in relation to a core telecommunications carrier servicing an owner of the TN. The porting activity may include at least one of port in, port out, and migration of the TN. In one embodiment, the planned porting activity for the TN associated with the LNP order is known prior to determining whether the porting activity has been completed. Other embodiments are also disclosed.
Abstract:
According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes submitting a local number portability (LNP) order for the TN directly to a first telecommunications carrier that the TN is to be transferred from, triggering a port of the TN in accordance with the LNP order, and porting the TN from the first telecommunications carrier to the second telecommunications carrier, wherein the second telecommunications carrier is bypassed by the customer during the submitting and the triggering of the LNP order. Other embodiments are also disclosed.
Abstract:
The present invention relates to X-ray generating technology in general, in particular, it relates to an anode disk element (1) for an X-ray generating device (21). The generation of electromagnetic radiation may be considered to be quite inefficient, since a substantial part of energy applied to a focal track is converted to heat rather than X-radiation. Thus, a limiting factor in the operation of X-ray tubes is the cooling of the anode element and more specifically the focal track. In the present invention, an anode disk element is provided, with an improved dissipation of heat from the focal track. Thus, the anode disk element may sustain increased heat while maintaining structural integrity. The anode disk element (1) comprises at least a first surface (2) and a second surface (3), with the first surface (2) comprising a focal track (4) and the second surface (3) comprising a conductive coating (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The first surface (2) comprising the focal track (4) and the second surface (3) comprising the conductive coating (5) are adjacently arranged.
Abstract:
A system and method for cross-authoritative, user-based network configuration management is provided. Users log-in to a network using any device coupled to the network, and an identity manager may provide the user with a custom computing environment by verifying the user's identity and identifying content, assignments, and other configuration information associated with the user. For instance, the identity manager may retrieve a unique identifier assigned to the user, query one or more authoritative source domains based on the unique identifier, and deliver a computing environment assigned to the user. By seamlessly integrating multiple authoritative sources, administrators can make assignments to users across multiple authoritative source domains, and queries to the sources will always be up-to-date without having to perform synchronization processes.
Abstract:
According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes placing a local number portability (LNP) order for the TN to be serviced by a core telecommunications carrier; and triggering the port of the TN via the core telecommunications carrier to occur prior to a time during which a typical port of the TN would have automatically occurred. A customer-initiated triggering may occur on a firm order commitment date associated with the LNP order. Other embodiments are also disclosed.

Abstract:
Medical devices are made visible under ultrasonic or magnetic imaging techniques by adding a series of features on their surfaces. The features are desirably placed at more than one angle to the surface in order to enhance the visibility of the surface. Laser-machining can make a series of depressions or voids that are symmetric with respect to the surface and another series of depressions or voids that are non-symmetric. The pattern of voids is also varied by using more than one size of void, the depth of the voids, and the distribution of voids, i.e. more voids in some areas than others.
Abstract:
A process that assists with the identification of potential hydrocarbon deposits that includes performing a structural interpretation of a three-dimensional seismic volume, transforming the three-dimensional seismic volume into a stratal-slice volume, performing a stratigraphic interpretation of the stratal-slice volume which includes the extracting of bounding surfaces and faults and transforming the stratal-slice volume into the spatial domain. As illustrated in FIGS. 24a, b and c, an exemplary seismic volume before Domain Transformation is presented in FIG. 24a, interpreted horizons and faults used in the transformation are presented in FIG. 24b, and the Domain Transformed stratal-slice volume is presented in FIG. 24c. The input seismic volume in FIG. 24a has deformations associated with syn- and post-depositional faulting. The output Domain Transformed volume (FIG. 24c) is substantially free of deformations.
