Abstract: The architecture of the present invention is premised upon an algorithm involving integration of oblique correlators and RAKE filtering to null interference from other spread spectrum signals. The oblique correlator is based on the non-orthogonal projections that are optimum for nulling structured signals such as spread spectrum signals. In one configuration, space spanned by a first signal associated with a first emitter is orthogonal to an interference space associated with one or more signals of one or more other emitters. RAKE filtering is used to rapidly steer the beam of the multi-antenna system and to mitigate the effects of multipath.

Abstract: Methods and compositions are described for the treatment of type I insulin-dependent diabetes mellitus and other conditions using newly identified stem cells that are capable of differentiation into a variety of pancreatic islet cells, including insulin-producing beta cells, as well as hepatocytes. Nestin has been identified as a molecular marker for pancreatic stem cells, while cytokeratin-19 serves as a marker for a distinct class of islet ductal cells. Methods are described whereby nestin-positive stem cells can be isolated from pancreatic islets and cultured to obtain further stem cells or pseudo-islet like structures. Methods for ex vivo differentiation of the pancreatic stem cells are disclosed. Methods are described whereby pancreatic stem cells can be isolated, expanded, and transplanted into a patient in need thereof, either allogeneically, isogeneically or xenogenically, to provide replacement for lost or damaged insulin-secreting cells or other cells.

Abstract: A composite tension rod is received in the sleeve portion of a shank that forms part of a terminal fitting, and is spaced from the shank sleeve and connected thereto by a potting resin. The shank sleeve wall tapers out from thin at its distal end to thick at the bury depth of the rod. The rod is tapered outwardly from a point of minimum diameter at its inner end to its full diameter a given distance from the end. The shank sleeve and rod have complementary dual tapering along said length such that as the diameter of the rod along said distance increases, the wall thickness of the shank sleeve decreases. The resin layer and the rod are secured to each other against relative longitudinal movement, as are the resin layer and the shank sleeve. In another aspect of the invention, a tension rod sleeve is fixed to the tension rod and extends over the distal end of the shank sleeve and along all or a majority of the length of the shank sleeve.

Abstract: The present invention is an orally administered pharmaceutical composition that provides for the controlled release of magnesium. The composition has an interactive agent component and a magnesium component which has an enteric coating that controls the release of the magnesium until the composition is in the small intestine or colon. The other component is released in the stomach and is substantially absorbed prior to the release of the magnesium component. Normally, the interactive agent component decreases the absorption of magnesium when the two components are released simultaneously in the gastrointestinal tract.

Abstract: An update process is used to update root certificates in a root certificate store of a client computer, maintaining the integrity of the existing root certificates as well as any new root certificates. In one embodiment, the root certificate store is updated by adding root certificates to the store, removing root certificates from the store, or modifying usage restrictions of root certificates in the store. A cryptographically signed message including a certificate trust list, as well as any new root certificates to be added to the root certificate store, is accessed by an update root control to update the root certificates in the root certificate store. The update root control verifies the integrity of the message, and thus the integrity of the certificate trust list contained therein. Once such integrity is verified, the update root control proceeds to update the root certificate store in accordance with the information in the certificate trust list.

Abstract: Systems and methods for assisting in location estimation are presented. In one embodiment of the invention, a system improves performance of known location determination algorithms through the use of interference cancellation. In general, the system selectively cancels certain signals to improve Signal to Noise Ratios (SNRs) of certain other signals in a spread spectrum system. These improved SNRs enhance processing, which assists in ascertaining a location of a mobile handset. For example, with improved SNR, the handset may be more able to process signals from more base stations. This processing of additional signals can improve location estimation because certain known location determination algorithms can be used (e.g., TOA and AOA) and location ambiguities and can be resolved.

Abstract: The present invention provides systems and methods for decreasing interference in a selected coded signal. The system includes a matrix generator for generating a matrix. The matrix may comprise vectors the elements of which are formed from components of the interference. The interference may exist in the form of co-channel and/or cross channel interference, such as that found in CDMA telephony. The components of this interference may, therefore, be code components of the interference that are used to fill elements of the vectors. Each element of a vector may represent a code component of an interfering coded signal. A processor uses the matrix to substantially remove the interference from the selected coded signal. For example, the processor may generate a projection operator that projects the coded signal substantially orthogonal to the interference such that the impact of interference on the selected coded signal is substantially reduced.

Abstract: A method and receiver are disclosed for mitigating or substantially canceling signal interference between signals detected at the receiver. Once a presumed interfering signal(s) is acquired, parameters are determined that allow the interferer(s) to be modeled. An orthogonal projection (for projecting onto a subspace orthogonal to that spanned by the interferer(s)) is applied to the composite of all signals (y) for thereby projecting y onto this subspace, wherein the subspace is non-orthogonal to a representation of desired (but interfered) signal of the composite signals. With the receiver properly equipped to perform this projection operation, interfering signals, multipath, spoofing and/or meaconing can be effectively diminished.
