Title: Securely processing client credentials used for web-based access to resources
Inventor: BRACEWELL SHAWN DEREK
IPC: G06F21/31
Filed: 2003-11-18
Abstract: The present invention provides for securely processing client credentials us ed for Web-based access to resources. A login page with an interface for entering user credentials is presented at a client and entered user credentials are sent to the server . In response to receiving user credentials, the server generates a unique session identifier for the client. The server also derives a digital signature for the user credentials based on a current key in a rotating key store and the unique session identifier. The server then encryp ts the digital signature and the user credentials based on an encryption key derived from t he current key and the unique session identifier. When encrypted credentials are received back at the client, keys from the rotating key store are used to attempt to validate the credentials. If user credentials can not be validated, a user is again presented with the login page.

Abstract: A stent or other intraluminal medical device may be constructed utilizi ng a series of split-bridges interposed between a series of fixed bridges to reduce the likelihood of deformation during stent loading and stent deployment without sacrificing overall stent flexibility. The stent comprises a plurality of hoops interconnected by a plurality of fixed bridges. The stent also comprises a plurality of split-bridges, which only make contact when the stent is subjected to compressive axial loading. The stent may also comprise markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent. This design provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stem under X-ray fluoroscopy. The housings are formed integral to the stem and the marker inserts are made from a material close in the galvanic series to the stent material and sized to substantially minimize the effect of galvanic corrosion. The housings are also shaped to minimize their impact on the overall profile of the stent.

IPC: G01N22/02

Abstract: A method for lost speech samples recovery in speech transmission systems is disclosed. The method employs a waveform coder operating on digital speech samples. It exploits the composite model of speech, wherein each speech segment contains both periodic and colored noise components, and separately estimates these two components of the unreliable samples. First, adaptive FIR filters computed from received signal statistics are used to interpolate estimates of the periodic component for the unreliable samples. These FIR  filters are inherently stable and typically short, since only strongly correlated elements of the signal corresponding to pitch offset samples are used to compute the estimate. These periodic estimates are also computed for sample times corresponding to reliable samples adjacent to the unreliable sample interval. The differences between these reliable samples and the corresponding periodic estimates are considered as samples of the noise component. These samples, computed both before and after the unreliable sample interval, are extrapolated into the time slot of the unreliable samples with linear prediction techniques.  Corresponding periodic and colored noise estimates are then summed. All required statistics and quantities are computed at the receiver, eliminating any need for special processing at the transmitter. Gaps of significant duration, e.g., in the tens of milliseconds, can be effectively compensated.
