    Abstract: Method of identification and quantitative analysis of primary and/or secondary amine(s) in a sample by mass spectrometry using stable isotope labeled internal standard is provided. Said internal standard is prepared by reaction of an authentic sample of said amine with a stable isotope labeled reagent, and is added to a sample containing said amine. Said amine in said sample is then quantitatively converted to a chemical compound of identical structure, except the stable isotope atoms, as that of said internal standard using a non-labeled reagent. Said sample is then extracted and the extract is analyzed by mass spectrometry. Identification and quantification of said amine are made from a plot of ion ratio of said converted amine to said internal standard versus amine concentration.

    Abstract: The present invention provides for giving preference to a specific media gateway in the selection of the next circuit so that in a multi-media-gateway soft-switch where a call may take any of many possible paths, an outgoing circuit on the same media-gateway as the incoming circuit is preferably selected, so if one is available, the need for using more bearer ports on media gateways to bridge the two sides is eliminated. Instead of interconnection, the same facilities can be provisioned to the bearer interface between the soft-switch and the rest of the network. This invention maximizes the bearer capacity of a distributed media gateway for external network access.

    Abstract: Apparatus and methods for managing, manipulating and presenting data objects within a graphical user interface with variable dimensions, shapes, locations and interactions. The apparatus and methods allow for variable data objects to be both pinned and liquid depending on a larger management and manipulation apparatus. The apparatus consists of databases that store the data objects to be displayed within the user interface and the layout coordinates, variable potential object size, and whether the object can move or not based on the graphical user interface dimensions. The object manipulations include the representation of such objects on the graphical user interface in a defined sequence.

    Abstract: A data processor includes a first bit field of a first plurality of bits representing a mantissa of a floating point number and a second bit field of a second plurality of bits representing an exponent of the floating point number. The first plurality of bits is partitioned into a plurality of regions, each of the plurality of regions comprises more than one bit of the first plurality of bits. A leading zero anticipator or other type of leading bit indication circuit is coupled to each region and determines a position of a leading bit of the first plurality of bits. A normalizer is coupled to receive a region of the plurality of regions that contains the leading bit, the normalizer may normalize or denormalize the region to produce a normalized or denormalized floating point number.
